"A reduction in lung capacity to oxygenize blood as well as in cardiovascular capacity to distribute blood may cause hypoxemia, which could then lead to tissue hypoxia and cellular death. The aim of oxygen treatment is to supply the minimum oxygen concentration needed to achieve adequate tissue oxygenation. There are various methods that can be used to supply oxygen, and the amount of oxygen requirement could also be calculated. Treatment methods are classified into STOT and LTOT. The benefit of oxygen treatment is increased survival, influence on the blood vessels, improved exercise capacity, and positive influence on the respiratory and neuropsychological systems. As with the case with pharmacological treatment, oxygen should be administered at certain doses to achieve greatest efficacy with the least toxicity."

"Tujuan : Menilai korelasi antara kelentutan atrioventrikular (Cn) dengan tekanan sistolik arteri pulmonal dan besarnya penurunan tekanan arteri pulmonal segera setelah dilakukan komisurotomi mitral transvena perkutan (KMTP). Latar Belakang : Pada pasien stenosis mitral (SM) terjadinya peningkatan tekanan arteri pulmonal dan beratnya gambaran klinis tidak selalu berkaitan dengan area efektif katup mitral (MVA) serta perbedaan tekanan transmitral (MVG) karena beberapa penelitian menunjukkan bahwa kelenturan atrioventrikular (Cn) juga mempengaruhi. Metode : Merupakan studi potong lintang yang dilakukan pada 30 pasien SM berat yang menjalani KMTP di PJNHK dari bulan Januari 2008 s/d oktober 2010. Pasien dibagi 2 kelompok, yakni kelompok I dengan Cn ::; 4 ml/mmHg dan kelompok II dengan Cn > 4 ml/mmHg. Pemeriksaan ekokardiografi dengan Vivid 7 dilakukan sebelum KMTP dan dalam 24 sampai 72 jam setelah KMTP. Cn ditentukan dengan persamaan : Cn = 1,270 (MV A I E-wave downslope), dan tekanan sistolik arteri pulmonal (sPAP) =Tricuspid valve gradient (TVG) + 10 mmHg. Hasil : Dari 194 subjek yang menjalani KMTP didapatkan sampel 30 orang yang memenuhi kriteria inklusi dan eksklusi. Proporsi kasus SM pada penelitian ini lebih banyak pada perempuan yaitu 70% dan usia rata- rata 36 tahun. Perbandingan sPAP pada kedua kelompok, baik sebelum ( 66,8 ± 21,7 mmHg V s 71,5 ± 31,5 mmHg, P = 0,64) maupun setelah KMTP ( 49,3 ± 10,8 mmHg Vs 56,4 ± 19,9 mmHg, P = 0,31) tidak berbeda bermakna, demikian pula besamya penurunan sPAP setelah KMTP pada kedua kelompok tidak berbeda bermakna ( 17,7 ± 15 mmHg Vs 15,7 ± 15,8 mmHg, P = 0,60). Kesimpulan : Kelenturan atrioventrikular (Cn) tidak mempengaruhi tekanan arteri pulmonal dan besamya perubahan tekanan arteri pulmonal segera setelah KMTP.......Objectives : The purpose of this study is to evaluate the correlation beetwen Cn with systolic artery pulmonal and the magnitude of decreasing systolic pulmonary pressure after balloon mitral valvuloplasty. Background : In patients with mitral stenosis (MS), the increase in pulmonary arterial pressure and severity of the clinical symptom are not only related to the mitral valve area and mitral vave gradient, but also related to the atrioventricular compliance (Cn). Methods : This is a cross sectional study in Thirty patients with severe mitral stenosis underwent Balloon Mitral Valvuloplasthy (BMV) procedure in NCCHKfrom January 2008 until October 20 I I. The patients were divided into two group, group I with Cn ~ 4 ml/mmHg and group II with Cn > 4 ml/mmHg. Echocardiograpy was done before BMV and 24 unti/72 hours after BMVwith vivid 7. Cn was derivedfrom the equation that has been previously validated (ie, Cn = I270 x [MV area by PHT I mitral Ewave downslope] and systolic pulmonary artery pressure(sPAP) = Tricuspid valve gradient (TV G) + I 0 mmHg. Results : There were I94 patients underwent BMV, but only 30 patients meet the inclusion and exclusion criteria. The women proportion were 70% and average of ages were 36 years old. The systolic pulmonary artery pressure in both group were not difference before ( 66,8 ± 2I, 7 mmHg Vs 7I,5 ± 3I,5 mmHg, P = 0,64) and after BMV ( 49,3 ± I0,8 mmHg Vs 56,4 ± I9,9 mmHg, P = 0,3I) and also the magnitude of decreasing systolic pulmonary artery pressure after BMV not difference between the groups. Conclusion: In patients with severe mitral stenosis, atrioventricular compliance was not affected systolic pulmonary artery pressure before and after BMV nor the magnitude of systolic pulmonaty artery pressure after BMV."

"Latar belakang: Defek septum ventrikel (DSV) merupakan salah satu PJB dengan jumlah kasus terbanyak. Hipertensi pulmonal merupakan salah satu komplikasi yang dapat terjadi dengan prevalensi antara 2-10% dari seluruh kasus DSV. Pasien yang datang ke Rumah Sakit Pusat Jantung Nasional Harapan Kita (RSPJNHK) sudah dengan kondisi hipertensi pulmonal dan usia dewasa. Adanya perubahan pedoman internasional AHA/ESC dalam menentukan kelayakan operasi pada pasien DSV. Perlu dilakukan penelitian mengenai hubungan nilai pulmonary artery resistance index (PARI) yang menjadi prediktor keluaran pada pasien yang dilakukan operasi penutupan DSV.Metode: Penelitian ini adalah studi kohort retrospektif berdasarkan data sekunder dari bagian rekam medis RSPJNHK Indonesia pada dewasa yang telah menjalani operasi tutup defek ventrikel pada periode 2015-2022. Variabel yang dinilai antara lain nilai pulmonary artery resistance index (PARI), lama penggunaan mesin jantung paru, lama penggunaan klem silang aorta, terhadap lama rawat, komplikasi pascaoperasi, dan kematian dini.Hasil: Terdapat 66 subjek pada penelitian ini. Usia rerata subjek studi ini 22,5 tahun. Pada penelitian ini terdapat peningkatan yang bermakna pada durasi ventilator (p = 0,012) dan lama rawat ICU (p = 0,031) pada kelompok nilai PARI >5 WU dibandingkan dengan kelompok PARI < 5 WU. Keluaran kelompok nilai PARI <5 WU lebih baik dibandingkan kelompok PARI >5 WU dengan mortalitas (0% vs 15,6%, p = 0,02), kejadian aritmia (14,7% vs 15,6 %; p = 0,59), dan krisis hipertensi pulmonal (0% vs 9,4%, p = 0,1)Simpulan: Terdapat hubungan antara nilai PARI dengan durasi ventilator mekanis dan lama rawat di ICU, namun tidak terdapat hubungan dengan aritmia dan kejadian krisis hipertensi pulmonal pascaoperasi. Terdapat hubungan yang bermakna antara nilai PARI dan mortalitas dini pascaoperasi penutupan defek septum ventrikel pada dewasa.......Background: Ventricular septal defect (DSV) is one of the most common CHDs. Pulmonary hypertension is one of the complications that can occur with a prevalence of between 2-10% of all DSV cases. Patients who come to Harapan Kita National Heart Center Hospital (RSPJNHK) already have pulmonary hypertension and are adults. There are changes in AHA/ESC international guidelines in determining the feasibility of surgery in DSV patients. It is necessary to conduct research on the relationship between the value of the pulmonary artery resistance index (PARI) which is a predictor of outcome in patients undergoing DSV closure surgery.Method: This study is a retrospective cohort study based on secondary data from the medical record section of the Harapan Kita National Cardiovascular Center Hospital in adult patients who had undergone ventricular septal defect closure surgery in the 2015-2022 period. The variable assessed included pulmonary artery resistance index (PARI), duration of cardiopulmonary bypass, duration of aortic cross clamp, on length of stay, postoperative complications, and mortality.Result: There were 66 subjects in this study. The mean age of the subjects was 22.5 years. In this study, there was a significant increase in ventilator duration (p = 0,012) and ICU length of stay (p = 0,031) in the PARI value >5 WU group compared to the PARI <5 WU group. The outcome of the PARI <5 WU group was better than the PARI >5 WU group with mortality (0% vs 15,6%, p = 0,02), arrhythmic events (14,7% vs 15,6 %; p = 0,59), and pulmonary hyperetension crisis (0% vs 9,4%, p = 0,1).Conclusion: There is an association between PARI and duration of mechanical ventilation and length of ICU stay, but no association with arrhythmias and the incidence of postoperative pulmonary hypertensive crisis. There is a significant association between PARI and early mortality after ventricular septal defect closure surgery in adults."

"Latar Belakang: Hipertensi arterial paru (HAP) memiliki mortalitas yang tinggi. HAP dapat disebabkan oleh defek septum atrium sekundum (DSAS). DSAS dengan HAP perlu diperiksa dengan kateterisasi jantung kanan (KJK) untuk menilai resistensi vaskular paru (RVP). Pengukuran pulmonary artery compliance (Cp) dengan cara invasif merupakan prediktor miliki nilai prognostik untuk meramalkan penyakit vaskular paru (PVP) dan mortalitas dibanding RVP. Fasilitas KJK belum tersedia merata di Indonesia. Gambaran notch pada kurva PW Doppler alur keluar ventrikel kanan (AKVKa) ditemukan pada pasien dengan Cp rendah. Karena itu, kami mencoba mencari korelasi antara time-tonotch dengan Cp yang didapat secara invasif. Tujuan: Penelitian ini bertujuan untuk mengetahui apakah terdapat korelasi antara time-to-notch dengan Cp pada pasien DSAS. Metode: Penelitian ini merupakan studi potong lintang dengan consecutive sampling pada pasien DSA sekundum dewasa (≥ 18 tahun) yang menjalani kateterisasi jantung kanan (KJK) di Rumah Sakit Jantung dan Pembuluh Darah Harapan Kita sejak Maret 2019 sampai Juni 2022. Parameter time-tonotch dari ekokardiografi akan diuji korelasinya dengan Cp yang didapat dari KJK. Hasil: Terdapat 84 pasien DSAS yang dilakukan analisis. Dari korelasi bivariat didapatkan bahwa time-to-notch memiliki korelasi positif sedang dengan Cp (r = 0,575, p < 0.0001). Variabel lain yang bermakna dalam uji bivariat adalah TRVmax, AKVKa VTI, PVAccT, TAPSE dan hemoglobin. Melalui regresi linier didapatkan bahwa variabel time-to-notch, TRVmax dan TAPSE dapat memprediksi Cp (R2 =0,49). Kesimpulan: Terdapat korelasi positif dengan kekuatan sedang antara time-to-notch dan Cp pada pasien DSAS. Kombinasi time-to-notch, TRVmax dan TAPSE dapat memprediksi Cp........Background: Pulmonary arterial hypertension (PAH) is a devastating condition with a high mortality rate. Secundum atrial septal defect (ASD) may cause PAH. It needs right heart catheterization (RHC) to assess pulmonary vascular resistance (PVR) in such patients. Pulmonary artery compliance (Cp) is another parameter gained from RHC that has better diagnostic and prognostic value to assess PAH compared to RVP. RHC facility is still not widely available in Indonesia. Low Cp is one of the factors influencing the notching in the right ventricular outflow tract (RVOT) PW Doppler curve. Therefor we try to find the correlation between time-to-notch and Cp. Objective: The study aims to evaluate correlation between time-to-notch and Cp in patients with secundum ASD. Methods: This is a cross sectional study with consecutive sampling in grown-up secundum ASD patients (≥ 18 years old) undergoing right heart catheterization (RHC) in National Cardiac Centre Harapan Kita from March 2019 to June 2022. The correlation between time-to-notch gained from echocardiography and Cp gained from RHC are then assessed. Results: There are 84 patients with secundum ASD included for analysis. From bivariat correlation time-to-notch and Cp have positive moderate correlation (r = 0.575, p < 0.0001). Other variables that also have significant correlation with Cp include TRVmax, RVOT VTI, PVAccT, TAPSE, and haemoglobin. However, multivariate analysis shows that only time-to-notch, TRVmax and TAPSE can predict Cp (R2= 0.49). Conclusions: There is moderate positive correlation between time-to-notch and Cp in secundum ASD. Combination time-to-notch, TRVmax and TAPSE can predict Cp."
