"Penggantian katup aorta dengan katup mekanik memerlukan biaya mahal, meningkatkan risiko endokarditis dan tromboemboli, serta memerlukan antikoagulan seumur hidup. Perikardium autolog merupakan alternatif untuk penggantian katup aorta. Tujuan penelitian ini adalah membandingkan luaran penggantian katup aorta antara katup mekanik dan perikardium autolog dengan teknik strip tunggal perikardium. Penelitian ini merupakan uji klinis terandomisasi di Pelayanan Jantung Terpadu Rumah Sakit Cipto Mangunkusumo (PJT-RSCM). Subjek dibagi ke dalam 2 kelompok berdasarkan jenis katup yang diterima, yaitu katup mekanik (kelompok mekanik) dan strip perikardium (kelompok strip). Luaran left ventricular reverse remodeling (LVRR), 6 minute walking test (6MWT), dan kadar soluble suppression of tumorigenicity-2 (sST-2) diperiksa preoperasi, 3 bulan, dan 6 bulan pascabedah. Terdapat 34 subjek yang ikut serta dari Juli 2016-Februari 2022, 17 subjek pada masing-masing kelompok. Tidak terdapat beda kejadian LVRR pada kedua kelompok, yaitu 26,7% pada kelompok mekanik dan 29,4% pada kelompok strip (p = 0,703). Pada pemeriksaan jarak 6 minute walking test (6MWT) tidak terdapat perbedaan bermakna jarak 6MWT antara kelompok strip perikardium dan kelompok mekanik pada 6 bulan pascabedah, yaitu 431,93 (SB 93,41) m vs. 404,28 (SB 79,25) m, p = 0,427 pascabedah. Kadar sST-2 kelompok mekanik 16,12 (SB 5,92) pg/mL secara bermakna lebih tinggi dibandingkan kelompok strip 11,52 (SB 6,96) pg/mL, p = 0,023) pada 6 bulan pascabedah. Disimpulkan teknik strip tunggal perikardium memiliki luaran yang sebanding dengan katup mekanik sehingga dapat digunakan sebagai alternatif penggantian katup aorta.

Aortic valve replacement with mechanical valves are quite expensive, increased the risk of adverse events such as endocarditis and thromboembolism, and requires patients to take anticoagulants for the rest of their life. Autologous pericardium is an alternative for aortic valve replacement. This study aims to compare outcomes of aortic valve replacement using mechanical valve and prosthetic valve with single-strip pericardium technique. This was a randomized clinical trial conducted at the Cipto Mangunkusumo Hospital (PJT-RSCM). Eligible subjects were randomized to either receive mechanical valve (mechanical group) or single-strip pericardium (single-strip group). Outcome assessments of left ventricular reverse remodeling (LVRR), 6 minute walking test (6MWT), and soluble suppression of tumorogenicity-2 (sST-2) were carried out at preoperation, 3 months, and 6 months postoperation. There were 34 subjects recruited from July 2016 to February 2022, 17 subjects in each groups. There was no difference in postoperative LVRR incidence between both groups, 26.7% in mechanical group vs. 29.4% in single strip group (p = 0.703). There was no significant difference of 6MWT between the mechanical and pericardial strip at six months post-operation, 404.28 (SD 79.25) m vs. 431.93 (SD 93.41) m, p = 0.427. The sST-2 level is significantly higher in mechanical group 16.12 (SD 5.92) pg/mL compared to single strip group 11.52 (SD 6.96) pg/mL, p = 0.023 at six months post-operation. We concluded that single strip pericardium technique showed comparable outcomes to mechanical valve and is considered a feasible alternative for aortic valve replacement."

Background: Rheumatic mitral valve diseases caused structural and electrical remodeling in the left atrium, resulting rhythm change from sinus to atrial fibrillation (AF). Left atrial surgical interventions (LASI) which consist of reduction of LA posterior wall to modify AF substrate and/or left atrial appendage (LAA) exclusion to isolate AF triggers may have beneficial effects on rhythm conversion during rheumatic mitral valve surgery. This study aimed to evaluate the short term effects of combined rheumatic mitral valve surgery and LASI for sinus rhythm conversion in patients with valvular AF. Methods: The subjects are AF patients with rheumatic mitral valve diseases undergoing mitral valve surgery from the period of January 2012-March 2018. Basic characteristics, preoperative and postoperative echocardiography parameters, surgical types, and ECG post-surgery were collected retrospectively from the patient's medical record. Statistical analysis were done using SPSS software.Results: There were 307 subjects who met the inclusion and exclusion criteria. They were divided into two groups: treatment group (combined mitral valve surgery plus LASI) consist of 180 patients, while control group (isolated mitral valve surgery) consist of 127 patients. In the control group, 25 (19.7%) subjects experienced sinus rhythm conversion immediately post-surgery, but no subjects maintained sinus rhythm conversion in the subsequent observation period (1-, 2-and 4-weeks post-surgery). While in the treatment group, there were 74 (41.1%), 10 (5.6%), 6 (3.3%), 4 (0.02%) subjects who experienced sinus rhythm conversion in the immediate (p<0.001 vs. control group), 1-week (p<0.01), 2-weeks (p<0.05) and 4-weeks (p=0.142) postoperative period, respectively. Multivariate analysis showed that LASI was an independent predictor of sinus rhythm conversion immediately post-surgery (RR: 2.84 95%CI 1.68-4.83; p<0.001), but not during the subsequent observations. Conclusions: The effects of combined rheumatic mitral valve surgery with LASI on rhythm conversion of valvular AF was observed during immediate postoperative period, but it had no significant effects during 1-week, 2-weeks and 4-weeks postoperative observations."

Background. Pulmonary hypertension is one of the long-term complication of mitral stenosis, resulting increase of morbidity and mortality. Pulmonary vascular resistance (PVR) is increase in reactive phase of pulmonary hypertension due to mitral stenosis. There is impaired autonom regulation following pulmonary hypertension, affecting heart rate changes during exercise test. Heart rate recovery (HRR) is defined as the difference between heart rate at peak exercise and 1 minute of recovery phase. It is affected by reactivation of parasympathetic system after cessation of exercise, and has been known as a long-term mortality predictor.

Method. A study of 20 patients with significant mitral stenosis with pulmonary hypertension who underwent mitral valve surgery in National Cardiovascular Center Harapan Kita was done from August to November 2014. PVR data from echocardiography was measured before surgery and before the patients were discharged. HRR data was taken from the treadmill test at the end of phase 2 cardiac rehabilitation program. Statistical analysis is done to explore the correlation between pulmonary vascular resistance and heart rate recovery after exercise test.

Result. Mean heart rate recovery after exercise test is 11,5 + 5,9 beat perminute, and changes of pulmonary vascular resistance after surgery is 1,55+2,1 WU. There was a correlation between change of PVR and heart rate recovery (r 0,537; p 0,015). Linear regression analysis of the change of PVR and heart rate recovery (unadjusted analysis) showed β coefficient 1,52 with 95% confidence interval 0,338-2,706 and p 0,015. Adjusted analysis to confounding variabel showed β coefficient 1,244 with 95% CI 0,032-2,457 and p 0,045.

Conclusion. Changes of pulmonary vascular resistance after mitral valve surgery in mitral stenosis pastient is positively correlated with heart rate recovery during exercise test."

"Latar Belakang : Stenosis mitral (SM) merupakan suatu lesi obstruksi katup mitral yang memerlukan terapi definitif suatu tindakan mekanik. Di Indonesia, prevalensinya masih cukup tinggi dengan penyebab yang multifaktorial; di antaranya waktu tunggu untuk antrian dari penjadwalan intervensi di era Jaminan Kesehatan Nasional. Kondisi pasien yang hadir terlambat dan waktu tunggu yang lama dapat memperburuk keadaan pasien. Pada SM, serangkaian neurohormonal teraktivasi. Penyekat enzim konversi angiotensin (EKA) dapat menghambat aktivasi renin-angiotensi-aldosteron (RAA), memperbaiki kondisi pasien selama menunggu jadwal operasi. Namun, pemberian penyekat EKA masih kontroversial. Tujuan : Untuk menilai keamanan dan pengaruh pemberian penyekat EKA dosis kecil pada pasien SM tanpa hipotensi terhadap six minute walk test (6MWT) dan N-Terminal pro B type natriuretic peptide (NT-proBNP). Metode : Penelitian ini merupakan studi eksperimental acak yang tersamar ganda. Sampel diambil secara konsekutif dan dilakukan randomisasi blok, untuk pemberian lisinopril 2,5 mg atau plasebo. Setiap subyek dilakukan ekokardiografi, 6MWT dan pemeriksaan laboratorium sebelum diberikan perlakuan. Evaluasi serupa dilakukan pada setiap subyek setelah 4 minggu. Hasil Penelitian : Terdapat 37 subyek yang berhasil dilakukan analisis; 19 pasien pada kelompok perlakuan dan 18 pasien pada kelompok kontrol. Tidak didapatkan perbedaan yang bermakna pada perubahan NT-proBNP dan 6MWT pada kedua kelompok (∆ NT proBNP 59 (-6747) - 2145) vs (-166) (-1495 - 1664) pg/mL; p = 0.443) dan (∆ 6 MWT 11.66 + 73 vs 21.37 + 47; p = 0.638). Tidak didapatkan pula perbedaan tekanan darah serta isi sekuncup yang bermakna antara kedua kelompok paska perlakukan, median isi sekuncup pada kelompok perlakuan 54 (34 - 74) vs 45 (34 - 94), p = 0.126.Kesimpulan : Pemberian penyekat EKA dosis kecil pada pasien SM tanpa keadaan hipotensi aman, namun tidak meningkatkan pencapaian 6MWT dan tidak meurunkan kadar NT-proBNP.

Background : Mitral stenosis (MS) is an obstructive lesion in which the definitive therapy is mechanical intervention. The prevalence of MS in developed countries has been decreasing due to the development of mechanical intervention. In Indonesia the prevalence remains high especially in the era of national health coverage, there are too many patients queuing for mitral valve operation. By this situation, we want to know if the angiotensin converting enzyme (ACE) inhibitor could reduce the burden of symptoms and other neurohormonal activation such as NT-proBNP in MS patients. There are many controversies to the use of ace inhibitor in MS patients, questioning the benefit and safety of ace inhibitor to these patients.

Objective : To study the safety and efficacy of low dose ACE inhibitor towards six minute walk test (6MWT) and N-Terminal pro B type natriuretic peptide (NT-proBNP) in Mitral Stenosis Patients without Hypotension.

Methods : This study is a double blind randomized control trial. Sample was taken consecutively, and randomized to be given lisinopril 2.5mg or placebo. Every patient was assigned for echocardiography evaluation, 6MWT, and laboratory examination before and after intervention.

Result : 37 patients were included in the analysis; 19 was in the intervention group, 18 patient was in the placebo group. No significant difference were found between the two groups in terms of NT-proBNP and 6MWT, (∆ NT proBNP 59 (-6747) - 2145) vs (166) (-1495 - 1664) pg/mL; p=0.443) dan (∆ 6 MWT 11.66 + 73 vs 21.37 + 47; p = 0.638). In terms of blood pressure and stroke volume, there was also no significant difference between the two groups after intervention, median for stroke volume in intervention group and control group were 54 (34 - 74) vs45 (34 - 94), p = 0.126.

Conclusion : Low dose ACE inhibitor is safe to be given in MS patient without hypotension, however, it did not increase functional capacity measured by 6MWT, neither improve NT-proBNP. "

"Latar Belakang: Pasien yang menjalani bedah katup mitral cenderung mengalami penurunan fungsi ventrikel kanan Vka pasca pembedahan katup. Disfungsi Vka pasca pembedahan katup dapat menetap ataupun mengalami perbaikan di kemudian hari. Banyak faktor yang dapat mempengaruhi perbaikan fungsi Vka pasca operasi. Namun, belum ada studi yang menilai faktor-faktor yang dapat menjadi prediktor perbaikan fungsi Vka pasca operasi katup mitral dalam suatu studi multivariat.Tujuan: Mengidentifikasi faktor-faktor apa saja yang dapat menjadi prediktor perbaikan fungsi Vka pada pasien dengan penyakit katup mitral yang mengalami disfungsi Vka segera setelah pembedahan katup mitral.Metode: Penelitian ini merupakan studi kohort retrospektif yang dilakukan di Rumah Sakit Jantung dan Pembuluh Darah Harapan Kita RSJPDHK . Subjek penelitian adalah pasien yang menjalani operasi katup mitral di RSJPDHK sejak Januari 2016 sampai dengan Februari 2017. Data yang diambil yakni karakteristik dasar, data operasi, data obat-obatan pasca operasi, pemeriksaan ekokardiografi sebelum, segera sebelum lepas rawat, dan enam bulan pasca operasi.Hasil penelitian: Sebanyak 100 subjek yang dinilai pada penelitian ini. Terdapat 68 68 subjek yang mengalami kenaikan fungsi Vka, dan 32 subjek 32 yang tidak. Median TAPSE sebelum lepas rawat meningkat secara signifikan enam bulan pasca operasi dari 1,1 0,6-1,5 menjadi 1,4 0,7-2,8 dengan nilai p

Background In patients undergoing mitral valve surgery, right ventricular function may decline immediately after the surgical procedure. This condition may sometimes remain, but may also improve later on. Many factors have been proposed to account for this phenomenon. As of yet, there are no studies using multivariate analysis to investigate factors that may be predictors of right ventricular function improvement after mitral surgery.

Objective This study aims to identify factors that may be predictors of right ventricular function improvement in patients with right ventricular dysfunction following mitral valve surgery.

Methods This is a retrospective cohort study, taking place at National Cardiovascular Center Harapan Kita NCCHK , Jakarta, Indonesia. Subjects are patients who underwent mitral valve surgery between January 2016 until February 2017. Data taken include basic characteristics, surgical data, drugs prescribed after surgery, and echocardiography data before surgery, predischarge, and six months after surgery.

Results There are 100 subjects who fulfilled the criteria to participate in this study. There are 68 68 cases of right ventricular function improvement and 32 32 cases without improvement. The median of predischarge TAPSE increases significantly six months after surgery, from 1,1 0,6 1,5 to 1,4 0,7 2,8 with p value."
