"Paralisis diafragma pasca operasi penyakit jantung bawaan dapat meningkatkan mortalitas dan morbitas pasien. Penegakkan diagnosa kelainan ini menjadi kunci untuk pengambilan keputusan tindak lanjut seperti plikasi diafragma. Fluoroskopi sebagai baku emas memiliki keterbatasan untuk dilakukan pada pasien pasca operasi penyakit jantung bawaan. Dari 2.287 operasi penyakit jantung yang dilakukan di RSJPDHK terdapat 41 pasien yang memenuhi kriteria inklusi dan eksklusi. Median usia pasien 10 (1-119) bulan dan 43,9% berjenis kelamin laki-laki. Terdapat perbedaan bermakna pada jenis operasi yang dijalani. Dari hasil perhitungan didapatkan sensitivitas dan spesifisitas USG diafragma dibandingkan fluoroskopi pada subjek penelitian sebesar 100%(95%CI 82,35%-100%) untuk sensitivitas, dan 95.5%(95% CI 77,16%-99,88%) untuk spesifisitas. Lebih lanjut dilakukan perhitungan nilai prediksi positif dengan hasil 95%(95%CI 73,68%-99,27%) dan nilai prediksi negatif 100% (95% CI 83,89%-100%). Ultrasonografi memiliki sensitivitas dan spesifisitas yang baik dibandingkan fluoroskopi sebagai metode diagnostik pada populasi dengan kecurigaan paralisis diafragma pasca operasi penyakit jantung bawaan dengan sensitivitas 100% dan spesifisitas 95.5%.

Diaphragmatic paralysis after congenital heart disease surgery can increase patient mortality and morbidity. Establishing a diagnosis of this disorder is key for making follow-up decisions such as diaphragm plication. Fluoroscopy as the gold standard has limitations for performing post-surgical patients with congenital heart disease.This study is a comparative diagnostic study that evaluates the ability of diaphragmatic ultrasound to diagnose diaphragmatic paralysis in patients with suspected diaphragmatic paralysis after surgery for congenital heart disease at RSJPDHK from June 2022 to May 2024. Each diaphragmatic ultrasound result was recorded and compared with the findings on fluoroscopy examination. Of the 2,287 heart surgery performed at RSJPDHK, there were 41 patients who met the inclusion and exclusion criteria. The median patient age was 10 (1-119) months and 43.9% were male. There are significant differences in the type of surgery undertaken. From the calculation results, it was found that the sensitivity and specificity of diaphragm ultrasound compared to fluoroscopy in research subjects was 100% (95% CI 82.35% - 100%) for sensitivity, and 95.5% (95% CI 77.16% - 99.88%) for specificity. Furthermore, the positive predictive value was calculated with results of 95% (95% CI 73.68%-99.27%) and negative predictive value of 100% (95% CI 83.89%-100%). Ultrasonography has good sensitivity and specificity compared to fluoroscopy as a diagnostic method in the population with suspected diaphragmatic paralysis after surgery for congenital heart disease with a sensitivity of 100% and a specificity of 95.5%."

"Latar belakang: EuroSCORE II (European System for Cardiac Operative Risk Evaluation) banyak digunakan sebagai model prediksi resiko mortalitas intrahospital dan juga mulai diteliti sebagai prediktor kesintasan jangka panjang untuk operasi jantung. Namun penggunaannya pada pembedahan katup jantung memilki nilai uji validasi yang buruk. TAPSE (Tricuspid Annular Plane Systolic Excursion), sebagai salah satu parameter fungsi ventrikel kanan diketahui menjadi salah satu prediktor pasien yang menjalani pembedahan jantung.Tujuan: Mengetahui perbandingan kemampuan prediksi mortalitas intrahospital dan kesintasan jangka panjang antara EuroSCORE II dengan kombinasi EuroSCORE II dan TAPSE (EuroSCOREII+TAPSE) dan kombinasi modifikasi variabel EuroSCORE II+TAPSE (Modified Euro-TAPSE-Score) pasien yang menjalani pembedahan katup jantung.Metode: Dilakukan studi kohort retrospektif terhadap 1842 pasien yang menjalani pembedahan katup jantung pada periode 2018-2021. Analisis bivariat dan multivariat antara nilai EuroSCORE II, variabel EuroSCORE II, dan TAPSE untuk mortalitas intrahospital dan kesintasan 4,5 tahun. Uji validasi dilakukan terhadap semua model prediksi resiko.Hasil: Mortalitas intrahospital yang diobservasi adalah 9,0 % dan untuk mortalitas jangka panjang adalah 18,8%. Sebagai prediktor mortalitas intrahospital, Modified Euro-TAPSE Score dan EuroSCOREII+TAPSE memilki nilai uji validasi yang lebih baik [(AUC 0,730; uji H-L p:0,988) vs (AUC 0,681; uji H-L p:0,065)] dibandingkan EuroSCORE II saja (AUC 0,686; uji H-L p:0,028). EuroSCORE II secara signifikan berhubungan dengan kesintasan jangka panjang (p<0,0001), namun TAPSE tidak dapat digunakan sebagai prediktor (p: 0,643) sehingga modifikasi EuroSCORE II dengan TAPSE tidak dapat dilakukan.Kesimpulan: Modified Euro-TAPSE-Score dan EuroSCOREII+TAPSE memiliki nilai prognostik yang lebih baik dibandingkan EuroSCORE II untuk mortalitas intrahospital pasien yang menjalani pembedahan katup jantung.

Background: EuroSCORE II (European System for Cardiac Operative Risk Evaluation) is widely used as a risk predictive model for intrahospital mortality and has been studied as a predictor of long-term survival for cardiac surgery. However, its use in valvular heart surgery (VHS) has poor validation test values. TAPSE (Tricuspid Annular Plane Systolic Excursion), as a parameter of right ventricular function is known to be one of the predictors of patients undergoing cardiac surgery

Objective: To compare the predictive ability of intrahospital mortality and long-term survival between EuroSCORE II with EuroSCORE II and TAPSE combination (EuroSCOREII+TAPSE) and EuroSCORE II variable modification with TAPSE (Modified Euro-TAPSE-Score) in patients undergoing VHS.

Metds: A retrospective cohort study was conducted on 1842 patients undergoing VHS in 2018-2021 period. Bivariate and multivariate analyzes of EuroSCORE II, EuroSCORE II variables, and TAPSE for intrahospital mortality and 4,5 year survival. Validation tests were carried out on all risk prediction models.

Results: The observed intrahospital mortality was 9,0% and long-term mortality was 18,8%. As predictors of intrahospital mortality, Modified Euro-TAPSE Score and EuroSCOREII+TAPSE have better validation test values [(AUC 0,,730; H-L test p:0,988) vs (AUC 0,681; H-L test p:0,065)] compared to EuroSCORE II (AUC 0,686; H-L test p:0,028). EuroSCORE II was significantly associated with long-term survival (p<0.0001), but TAPSE could not be used as a predictor (p:0,643) so EuroSCORE II modification with TAPSE could not be performed.

Conclusion: Modified Euro-TAPSE-Score and EuroSCOREII+TAPSE have a better prognostic value than EuroSCORE II for intrahospital mortality in patients undergoing VHS."

"Latar Belakang: Fibrosis ventrikel kanan merupakan respons adaptif sekaligus maladaptif terhadap kelebihan beban di ventrikel kanan. Peranan fibrosis ventrikel kanan pada populasi hipertensi pulmonal (HP) akibat defek septum atrial (DSA) sekundum belum banyak diketahui.Tujuan: Membandingkan derajat fibrosis ventrikel kanan pada pasien DSA sekundum yang sudah dan belum terjadi penyakit vaskular paru (PVP) serta menilai korelasi parameter fibrosis berdasarkan magnetic resonance imaging (MRI) dengan nilai pulmonary arterial resistance index (PARi), flow ratio (FR) dan rasio pulmonary vascular resistance/systemic vascular resistance (PVR/SVR) dari kateterisasi jantung.Metode: Penelitian ini merupakan studi potong lintang pada pasien DSA sekundum dengan HP berusia 318 tahun yang menjalani kateterisasi jantung kanan dan pemeriksaan MRI untuk menilai fibrosis ventrikel kanan.Hasil: Terdapat total 63 pasien yang ikut serta dalam penelitian. Sebanyak 92.1% pasien memiliki gambaran late gadolinium enhancement (LGE) di regio right ventricular insertion point dan 66.7 % di septum interventrikular. Kelompok yang sudah mengalami PVP memiliki skor LGE, nilai native T1 dan extracellular volume (ECV) yang lebih tinggi dibanding kelompok yang belum (berturut-turut, 3 [1-4] vs. 2 [0-4]; p = 0.001, 1192 [1043-1407] ms vs. 1118 [1019-1191] ms; p <0.001, 43.7 ± 5.5% vs. 38.1 ± 4.6%; p <0.001). Skor LGE memiliki korelasi sedang terhadap PARi (r = 0.581, p <0.001), PVR/SVR (r = 0.561, p <0.001) dan FR (r = -0.490, p <0.001). Nilai native T1 memiliki korelasi kuat terhadap PARi (r = 0.679, p <0.001) dan PVR/SVR (r = 0.627, p <0.001) serta korelasi sedang terhadap FR (r = -0.589, p <0.001). Nilai ECV memiliki korelasi sedang terhadap FR (r = -0.440, p <0.001), serta korelasi lemah terhadap PARi (r = 0.398, p = 0.001) dan PVR/SVR (r = 0.382, p = 0.001).Kesimpulan: Pasien DSA sekundum yang sudah mengalami PVP memiliki derajat fibrosis ventrikel kanan yang lebih berat serta terdapat korelasi bermakna antara fibrosis ventrikel kanan dengan parameter kateterisasi jantung.

Background : Right ventricular (RV) fibrosis is both adaptive and maladaptive response to the overloaded RV. Its role in pulmonary hypertension (PH) caused by secundum atrial septal defect (ASD) is not well known.

Aim(s): This study aims to compare RV fibrosis in patients with secundum ASD who have and have not experienced pulmonary vascular disease (PVD) and to determine the correlation of RV fibrosis with pulmonary arterial resistance index (PARi), flow ratio (FR), and pulmonary vascular resistance/systemic vascular resistance (PVR/SVR) ratio.

Method(s): This is a cross-sectional study on patients aged ≥18 years with secundum ASD and PH, who underwent right heart catheterization (RHC) and cardiac magnetic resonance imaging (MRI) to assess RV fibrosis.

Result(s): There were a total of 63 patients participating in this study. The majority of patients showed late gadolinium enhancement (LGE) in the region of RV insertion point (92.1%) and interventricular septum (66.7%). The PVD group had higher LGE scores, native T1, and extracellular volume (ECV) (3 [1-4] vs. 2 [0-4]; p = 0.001, 1192 [1043- 1407] ms vs. 1118 [1019-1191] ms; p <0.001, 43.7 ± 5.5% vs. 38.1 ± 4.6%; p <0.001, respectively). LGE scores had a moderate correlation with PARi (r = 0.581, p <0.001), PVR/SVR ratio (r = 0.561, p <0.001), and FR (r = -0.490, p <0.001). RV native T1 showed a strong correlation with PARi (r = 0.679, p <0.001) and PVR/SVR (r = 0.627, p <0.001), and a moderate correlation with FR (r = -0.589, p <0.001). RV ECV had a moderate correlation with FR (r = -0.440, p <0.001), and weak correlations with PARi (r = 0.398, p = 0.001) and PVR/SVR (r = 0.382, p = 0.001).

Conclusion: Secundum ASD patients with PVD showed significantly higher degree of RV fibrosis. There is a significant correlation between RV fibrosis and hemodynamic parameters obtained from RHC."

"Latar belakang: Aritmia ventrikular idiopatik, baik kompleks ventrikel prematur (KVP) maupun takikardia ventrikel (TV), dapat menyebabkan terjadinya penurunan fungsi sistolik ventrikel kiri (VKi) yang akan menimbulkan kardiomiopati dan meningkatkan mortalitas. Banyak faktor yang berkontribusi menyebabkan terjadinya kardiomiopati akibat KVP (KA-KVP) meskipun mekanisme terjadinya belum sepenuhnya dipahami. Variasi sirkadian KVP dilaporkan berhubungan dengan terjadinya penurunan fraksi ejeksi VKi. Deteksi dini adanya disfungsi sistolik intrinsik Vki dapat dilakukan melalui pemeriksaan speckle tracking ekokardiografi dengan mengukur nilai global longitudinal strain (GLS). Sampai saat ini belum diketahui apakah variasi sirkadian KVP berhubungan dengan penurunan fungsi sistolik intrinsik ventrikel kiri.Tujuan: Penelitian ini bertujuan untuk mengetahui hubungan antara variasi sirkadian aritmia ventrikular idiopatik dengan fungsi sistolik intrinsik ventrikel kiri melalui speckle tracking ekokardiografi.Metode: Penelitian ini adalah studi potong lintang dengan total subjek 67 pasien (17 laki-laki [25,4%]; usia rata-rata 46.5 + 9.8 tahun; fraksi ejeksi ventrikel kiri 63,2% + 7,5%) dengan KVP yang berasal dari jalur keluar ventrikel dari pemeriksaan elektrokardiogram 12 sadapan. Semua pasien menjalani pemeriksaan Holter monitoring 24 jam dan speckle tracking ekokardiografi. Dilakukan perhitungan variasi sirkadian beban KVP dan nilai global longitudinal global (GLS) kemudian dilakukan analisis statistik untuk menilai hubungan kedua variabel tersebut.Hasil: Sebanyak 31 pasien (46.3%) mengalami gangguan fungsi sistolik Vki (GLS lebih buruk dari -18%). Pasien dengan gangguan fungsi sistolik VKi memiliki GLS yang kurang negatif (-15.1% + 1.8% vs -21.3% + 2.0%; p=<0,001), beban KVP yang lebih tinggi (22.2% + 11.1% vs 13.9% + 8.3; p=0,001), variasi sirkadian beban KVP yang rendah (koefisien variasi beban KVP per 6 jam 26.8% + 15.6 vs 52.0 % + 28.2%; p=<0,001), dan episode TV non-sustained yang lebih sering (10 pasien [76.9%] vs 3 pasien [23.1%]; p=0,019). Sebanyak 70.6% pasien dengan jenis kelamin laki-laki mengalami gangguan disfungsi sistolik VKi (p=0,002). Pada analisis multivariat didapatkan beberapa prediktor terhadap gangguan fungsi sistolik Vki antara lain variasi sirkadian beban KVP yang rendah dengan [(koefisien variasi beban KVP per 6 jam < 35%), odds ratio (OR)=3.89 interal kepercayaan (IK)95%=1.09-13.80 p=0.036], episode TV non-sustained (OR=14.4, IK 95%=2.36-88.55, p=0.008), beban KVP > 9% (OR=6.81, IK 95%=1.35-34. Kesimpulan: Variasi sirkadian aritmia ventrikular idiopatik yang rendah berhubungan dengan penurunan fungsi sistolik intrinsik ventrikel kiri melalui speckle tracking ekokardiografi. Variasi sirkadian beban KVP per 6 jam < 35% memiliki risiko 3.89 kali lebih tinggi untuk terjadinya disfungsi sistolik ventrikel kiri

Background: Idiopathic ventricular arrhythmias (AVI) including premature ventricular complex (PVC) or ventricular tachycardia (VT) can cause left ventricular (LV) dysfunction which may lead to cardiomiopathy. The mechanisms of this cardiomyopathy remain elusive, many factors are believed to contribute. PVC burden is influenced by circadian rhythmicity and lack of PVC circadian variability was proposed as one mechanism of LV dysfunction. Since early detection of LV systolic dysfunction can be done by speckle tracking echocardiography examination, further studies are needed to assess intrinsic left ventricular systolic function and its correlation with PVC circadian variation in patients with idiopathic ventricular arrhythmias.

Objective: This study aimed to investigate the correlation between circadian variation of IVA and left ventricular intrinsic systolic function assessed by speckle tracking echocardiography.

Methods: The subjects of this cross sectional study were 67 consecutive patients (17 men [25.4%]; mean age 46.5 + 9.8 years; left ventricular ejection fraction 63.2% + 7.5%) with PVC originated from ventricular outflow tract based on 12 lead electrocardiogram. All patients underwent 24-hour Holter monitoring and speckle tracking echocardiography examinations. The circadian variation of PVC burden and global longitudinal strain (GLS) were determined and statistical analysis was conducted to evaluate their correlation. Results: A total 31 patients (46.3%) had impaired LV systolic function by GLS ( worse than -18%). Patients with impaired LV systolic function had a less negative GLS (-15.1% + 1.8% vs -21.3% + 2.0%; p=<0.001), a higher PVC burden ((22.2% + 11.1% vs 13.9% + 8.3; p=0,001), less variation in circadian PVC distribution (coefficient of variation 6 hourly 26.8% + 15.6 vs 52.0 % + 28.2%; p=<0.001), and more frequent episode of non-sustained VT (10 patients [76.9%] vs 3 patients [23.1%]; p=0.019). Total 70.6% patient with male gender experienced impaired LV systolic function (p=0.002). Independent predictors for impaired systolic LV function were less variation in circadian PVC distribution [(coeficient of variation < 35%), odds ratio (OR)=3.89, 95% confidence interval (CI)= 1.09-13.80, p=0.036)], episode of non-sustained VT (OR=14.4, 95%CI=2.36-88.55, p=0.008), PVC burden > 9% (OR=6.81, CI 95%=1.35-34.41, p=0.020), and male gender (OR=14.4, CI 95%=2.02-101.1, p=0.004).

Conclusion: Lack of circadian variation of IVA is associated with impaired LV systolic function by GLS. Coefficient of variation PVC burden < 35% has 3.89 times higher risk for development of left ventricular systolic dysfunction."

"ABSTRAKLatar belakang: Studi sebelumnya menyimpulkan bahwa mitral valve gradient (MVG) merupakan parameter selain area katup mitral (AKM) yang berhubungan dengan perbaikan gejala pasca komisurotomi mitral transkateter perkutan (KMTP). Oleh karena itu, studi diperlukan untuk menjelaskan hubungan MVG terhadap perbaikan gejala secara objektif, dalam bentuk kapasitas fungsional.Tujuan: Studi ini bertujuan untuk mengevaluasi hubungan MVG terhadap perubahan kapasitas fungsional pasca KMTP.Bahan dan Metode: Studi quasi experimental dengan one group pre-post design terhadap 78 subjek. Pemeriksaan ekokardiografi dan treadmill Bruce termodifikasi dilakukan 1-2 hari sebelum dan 1-2 minggu setelah KMTP. Data sebelum dan setelah KMTP dianalisis untuk mencari hubungan variabel terhadap perbaikan kapasitas fungsional pasca KMTP. Perbaikan kapasitas fungsional didefinisikan sebagai perubahan lama latihan > 180 detik pasca KMTP.Hasil: Rerata usia adalah 42 tahun, mayoritas perempuan (3,6:1) dengan rerata IMT 22,27 kg/m2. Sebesar 5,1% pasien merokok dengan komorbid stroke sebesar 14,1%. Sebelum KMTP, 53% memiliki irama sinus dengan mayoritas memiliki fungsi ventrikel kiri yang baik (rerata ejeksi fraksi 62%) dan fungsi ventrikal kanan yang baik (median tricuspid annular plane systolic excursion (TAPSE) 20 mm). Sebesar 97% pasien datang dengan kelas NYHA II sebelum KMTP dan mengalami perbaikan signifikan kapasitas fungsional pasca KMTP berupa perbaikan median lama latihan (241(18-1080) ke 603(30-1900) detik, p < 0,001) dan perbaikan median nilai VO2max estimasi (18,8(10,2-51,4) ke 32,8(10,6-83,2) mlO2/kg/menit, p<0,001). Dari uji korelasi, didapatkan variabel usia (r -0,23, adjusted R2=4,1%), pre-MVG (r 0,23, adjusted R2=4,2%), Δ MVG (r 0,31, adjusted R2= 9,0%) , dan pre-TR Vmax (r 0,3, adjusted R2=1,3%) berkorelasi terhadap perubahan kapasitas fungsional. Perbaikan kapasitas fungsional segera pasca KMTP tidak berhubungan dengan AKM pasca KMTP ≥ 1,5 cm2 (p= 0,14) dan perubahan AKM ≥ 200% pasca KMTP (p= 0,18). Penurunan MVG > 50 % pasca KMTP (OR 2,89, IK 95% 1,06-7,92; p = 0,038) dan TR Vmax sebelum KMTP > 3,4 m/s (OR 3,42, IK 95% 1,19-9,83; p = 0,023) merupakan prediktor perbaikan kapasitas fungsional segera pasca KMTP.Kesimpulan: Penurunan MVG lebih dari 50% pasca KMTP berhubungan dengan perbaikan kapasitas fungsional segera pasca KMTP.

ABSTRACTIntroduction: Previous studies had shown that mitral valve gradient (MVG) was other parameter than mitral valve area (MVA) which had correlation with symptom improvement post baloon mitral valvuloplasty (BMV). However, further study is needed to illuminate the assocation of MVG with clinical improvement objectively, in term of functional capacity.Objective: This study aimed to determine the association between MVG and functional capacity alteration after BMV.Material and Methods: Quasi exsperimental study with one group pre-post design was applied in 78 subjects. Echocardiography and Modified Bruce Protocol assessment were done 1-2 days before and 1-2 weeks after BMV. Pre and post data were analized to obtain association of variables with functional capacity alteration immediately after BMV. Improvement of functional capacity was defined as alteration of exercise time more than 180 seconds after KMTP.Results: The mean age was 42 y.o, female dominant (3,6:1), mean BMI was 22,27 kg/m2. Of 5,1% patient were smoker with most commonly observed comorbidities include stroke (14,1%). Majority 53% had sinus rhythm with dominant good left ventricular function (mean ejection fraction 62%) and good right ventricular function (median tricuspid annular plane systolic excursion (TAPSE) 20 mm). Of 97% patients presented with NYHA class II before BMV with significant improvement of functional capacity after BMV such as median exercise time alteration (241(18-1080) to 603(30-1900) s, p < 0,001) and median estimate VO2 max value alteration (18,8(10,2-51,4) to 32,8(10,6-83,2) mlO2/kg/minute, p<0,001). From correlation test, age (r -0,23, adjusted R2=4,1%), pre-MVG (r 0,23, adjusted R2=4,2%), Δ MVG (r 0,31, adjusted R2= 9,0%), and pre-TR Vmax (r 0,3, adjusted R2=1,3%) were corelated with functional capacity alteration. Improvement of functional capacity did not significantly associate with post MVA>1,5 cm2 (p= 0,14) and AKM alteration after BMV ≥ 200% (p= 0,18). Reduction of MVG > 50 % after BMV (OR 2,89, 95% CI 1,06-7,92; p = 0,038) and TR Vmax before BMV > 3,4 m/s (OR 3,42, 95% CI 1,19-9,83; p = 0,023) were predictor of functional capacity improvement immediately after BMV.Conclusions: Reduction of MVG more than 50% had association with immediate improvement of functional capacity post BMV."

"Latar Belakang: Isolasi vena pulmonalis merupakan strategi utama dalam tindakan ablasi fibrilasi atrium (FA). Namun, angka kekambuhan pasca ablasi FA masih signifikan. Substrat atrial seperti low voltage zone (LVZ) menggambarkan perubahan struktur dari atrium kiri. Low voltage zone berhubungan erat dengan kekambuhan pasca ablasi FA. Terdapat beberapa sistem skoring yang dapat memprediksi kekambuhan FA pasca ablasi FA yang menggunakan diameter atrium kiri, namun belum ada sistem skoring yang menggunakan indeks volume atrium kiri sebagai prediktor kekambuhan FA pasca ablasi. Skor ZAQ menggunakan IVAK MSCT, jenis kelamin perempuan dan usia ≥ 65 tahun untuk mempredikisi adanya LVZ.Tujuan: Penelitian ini bertujuan untuk mengetahui apakah terdapat perbedaan kekambuhan lambat pasca ablasi FA antara kelompok skor ZAQ < 2 dibandingkan dengan ≥2.Metode: Penelitian ini merupakan studi kohor retrospektif dengan menggunakan data sekunder dari pasien FA yang dilakukan isolasi vena pulmonalis pertama kali di RSJPDHK pada periode Januari 2015 sampai Agustus 2020. Dilakukan rekonstruksi IVAK dengan MSCT untuk menghitung skor ZAQ masing – masing pasien dan dilakukan evaluasi elektrokardiogram (EKG) 12 lead atau holter dalam waktu 3 sampai dengan 12 bulan pasca tindakan ablasi untuk melihat kekambuhan lambat.Hasil: Terdapat 77 pasien ablasi FA yang memenuhi kriteria inklusi dan eksklusi. Selama periode observasi, didapatkan 23 pasien (30%) yang mengalami kekambuhan lambat pasca ablasi. Dari hasil analisis regresi logistik multivariat, skor ZAQ bukan merupakan prediktor kekambuhan lambat pasca ablasi FA (OR 3.31; IK 95% 0.065 – 17.011; p=0.551). Yang menarik adalah kami menemukan dua variabel yang merupakan prediktor independen kekambuhan lambat pasca ablasi FA, yaitu IVAK MSCT ≥65.5 ml/m2 (OR 3.91; IK 95% 1.140-13.393; p=0.030) dan tipe FA non paroksismal (OR 5.00; IK 95% 1.552-16.150; p=0.007), sedangkan pemberian amiodarone pasca tindakan dapat memberikan efek protektif (OR 0.13; IK 95% 0.024-0.719, p=0.019).Kesimpulan: Tidak terdapat perbedaan kekambuhan lambat pasca ablasi FA antara kelompok skor ZAQ <2 dengan ≥2.

Background: Pulmonary vein isolation (PVI) is the main target for AF ablation. Unfortunately, the recurrence rate remains significant. Atrial substrate such as low voltage zones reflect the structural change of the left atrium. This LVZ is strongly associated with recurrence. There have been some scoring systems that predict AF reccurence after ablation using left atrial diameter, however there is no scoring system using left atrial volume index (LAVI) as a predictor for AF recurrence. ZAQ score employed MSCT LAVI, female sex, and age ≥ 65 years to predict the presence of LVZ.

Objective: This study aims to investigate the difference of late recurrence after AF ablation between ZAQ score <2 and ≥2.

Method: This study was a retrospective cohort study using secondary data collected from AF patients who underwent their first PVI during the period of January 2015 to August 2020 in National Cardiovascular Center Harapan Kita Hospital. LAVI reconstruction with MSCT was conducted to calculate ZAQ score of each patients. Twelve leads electrocardiogram (ECG) evaluation or Holter monitor within 3 to 12 months after ablation was conducted to evaluate late reccurence.

Result: There were 77 patients who met the inclusion and exclusion criteria. During the observation period, 23 patients (30%) experienced late recurrence post ablation. From multivariate logistic regression analysis, ZAQ score is not a predictor of late recurrence after AF ablation (OR 3.31; CI 95% 0.065 – 17.011; p=0.551). Interestingly, we found two variables which were independent predictors of late recurrence after AF ablation, i.e. MSCT LAVI ≥ 65.5 ml/m2 (OR 3.91; CI 95% 1.140-13.393; p=0.030) and non paroxysmal AF (OR 5.00; CI 95% 1.552-16.150; p=0.007), while amiodarone administration post-ablation had protective effect toward late recurrence (OR 0.13; CI 95% 0.024-0.719; p=0.019).

Conclusion: There was no difference in late recurrence after AF ablation between the ZAQ score group <2 and ≥2."

Infective endocarditis (IE) is a serious health problem with high incidence, morbidity, and mortality rates. Intrahospital antibiotic-related worsening of renal function occurs quite frequently and is associated with worse clinical outcomes. The objective of this study was to determine the relationship between antibiotic-related worsening of kidney function and intrahospital mortality in left-sided IE patients. A retrospective cohort study was conducted on 315 patients with active IE on the left side of the heart from January 1, 2013 to May 31, 2023. Bivariate and multivariate analyses were conducted to determine predictors of intrahospital mortality, long-term mortality, length of stay, and the need for renal replacement therapy. There were 315 patients with active IE on the left side of the heart, of whom 169 had antibiotic-related worsening of kidney function, and 146 did not. The intrahospital mortality rate was 20.3%, whereas the intrahospital mortality rate was 34.9% in patients with worsening kidney function due to antibiotics. According to multivariate analysis, factors associated with intra-treatment mortality were antibiotic-related worsening of kidney function (OR 8.6, p=0.001), incidence of sepsis (OR 11.16, p=<0.001), incomplete use of antibiotics (OR 10.49, p=<0.001), length of stay <21 days (OR 5.16, p=0.003), vegetation size >10 mm (OR 5.04, p=0.006), and use of renal replacement therapy (OR 4.74, p=0.008). We obtained the predictor score for intrahospital mortality. The results of the ROC curve analysis for calculating intrahospital mortality predictor scores showed an AUC of 0.927 (95% CI 0.886–0.968; p < 0.001; H-L 0.610) with a sensitivity of 89.1% and a specificity of 84.5%. Worsening kidney function related to antibiotics was associated with intrahospital mortality."
