Clinical Presentation and 6-Month Outcomes of Patients with Peripartum Cardiomyopathy in Indonesia.

Background: Due to the rarity of peripartum cardiomyopathy (PPCM) globally, baseline characteristic data for PPCM patients are still scarce. Therefore, this study aims to determine the baseline characteristics and 6-month outcomes of PPCM patients in Indonesia. Methods: From January 2014 to December 2021, all PPCM patients aged ≥18 years who were admitted to Dr. Hasan Sadikin General Hospital in Bandung, Indonesia, participated in this single-center, prospective cohort study. All patients were re-evaluated within 6 months of PPCM diagnosis. Results: A total of 138 patients with PPCM were admitted to Dr. Hasan Sadikin General Hospital in Bandung. The mean age of all patients was 30.4 ± 6.4 years old. Approximately 60% patients were multipara and had preeclampsia. All guideline-directed medical therapy for heart failure was received by most patients, excluding mineralocorticoid receptor antagonists (25.2%) and bromocriptine (14.1%). The neonatal mortality rate was 5.1%. Among those who survived, 61.2% had normal weight, 31.8% had low birth weight, and 7% had very low birth weight. At the 6-month follow-up, 6.7% of the patients died, 63.3% recovered, and 1.9% were rehospitalized. Conclusion: The present study found a high incidence of PPCM in Indonesia. Our patients frequently had preeclampsia, which contributed to the higher rate of miscarriage and low birth weight. Our liberal use of beta-blockers and ACEi/ARB may have contributed to the higher 6-month recovery rate than that in other countries.

A multidisciplinary approach of a patient with pheochromocytoma presenting as recurrent acute fulminant myocarditis: A rare case report and comprehensive review of literature.

Fulminant myocarditis (FM) is a rare illness characterized by abrupt and severe widespread cardiac inflammation, which frequently results in mortality due to cardiogenic shock, ventricular arrhythmias, or multiorgan system failure. Pheochromocytoma is an uncommon and difficult-to-diagnose cause of FM, and it is associated with a significant risk of recurrent acute myocarditis. There is, however, little information on reoccurring acute FM. Herein, we report a rare case of recurrent acute FM due to pheochromocytoma. We present the case of a 22-year-old woman who was admitted to our hospital three days previously with acute dyspnea. Five months prior, the patient was diagnosed with post-acute myocarditis, and a massive tumor on the right adrenal gland was discovered, which lead to pheochromocytoma diagnosis. In this present admission, following the exclusion of infection, autoimmune, and metabolic derangements, pheochromocytoma was presumed to be the reason for the recurrence and more severe acute FM during the current hospitalization. The patient responded favorably to high-dose steroids combined with heart failure therapy regimens. To detect recurrent acute myocarditis related to pheochromocytoma, a multidisciplinary approach was used, including several laboratory biomarkers and imaging findings. Following pheochromocytoma removal and biopsy, the patient recovered satisfactorily. Our findings may provide beneficial contributions to the literature as pheochromocytoma is an uncommon but important cause of recurrent acute myocarditis. A multidisciplinary approach is essential in identifying acute FM and determining the underlying causes of this malady.

Predicting poor left ventricular function recovery in Peripartum cardiomyopathy.

INTRODUCTION: Peripartum cardiomyopathy (PPCM) is a rare type of cardiomyopathy that manifests as acute heart failure associated with pregnancy. Delays in early identification result in poor recovery of left ventricular (LV) function; however, no risk prediction model exists. We sought to yield a scoring system known as the Padjadjaran Peripartum CardioMyopathy Recovery (PPCM recovery) score to predict the probability of poor LV function recovery in PPCM patients. METHODS: All baseline and clinical parameters were prospectively collected from a cohort of patients with PPCM admitted to Dr. Hasan Sadikin General Hospital in Bandung, Indonesia between January 2014 and December 2021. Logistic regression analyses were performed to investigate the relationship between each variable and the risk of poor LV function recovery in PPCM patients. RESULTS: This prospective cohort study included 113 patients with PPCM (84 recovered and 29 non-recovered patients). Significant mitral regurgitation (MR), left ventricular ejection fraction (LVEF) <30%, left ventricular end-diastolic diameter (LVEDD) ≥56 mm, and New York Heart Association functional class (NYHA FC) IV were all strong predictors of poor LV function recovery. These variables were integrated into the PPCM recovery score (AUC of 0.85). Patients with a score of ≥8 were nearly 18 times more likely to have poor LV function recovery (sensitivity 57%, specificity 93%). CONCLUSION: PPCM recovery score is a convenient scoring system based on clinical and echocardiography assessment that may assist in distinguishing which patients are more likely to develop poor LV function recovery; therefore, these patients should be immediately referred to a tertiary referral hospital.

Case Series: Extracorporeal Shockwave Myocardial Revascularization Therapy Improves Ischemic Response, Functional Capacity, and Quality of Life in Indicated CABG-Stable Angina Pectoris Patients.

INTRODUCTION: Extracorporeal shockwave myocardial revascularization (ESMR) is included in the guidelines only for patients with refractory angina pectoris having no option for invasive revascularization. We intend to report a case series with ESMR therapy is indicated patients with coronary artery bypass grafting-stable angina pectoris (CABG-SAP) who refuse the surgery, irrespective of angina symptoms. METHODS: We review medical records of patients with SAP admitted to ESMR therapy in Dr. Hasan Sadikin General Hospital, Bandung, Indonesia from January 2018 to December 2019. Recorded variables at baseline and after therapy extracted, namely, (1) ischemic response, double product, and (2) functional capacity measured as metabolic equivalent (MET) using treadmill test; (3) six-minute walking test distance achieved; and (4) quality of life using SF-36 Questionnaire. RESULTS: A total of four indicated patients with CABG-SAP from 50 to 75 years old were included in this study. At baseline, one patient is CCS class I and two patients are CCS class II with SDS ranging from 3 to 17. Ischemic response improved in all the patients. The double product improved in patient 1 9,600-14,872 mm Hg × bpm, patient 2 9,460-10,640 mm Hg × bpm, and patient 4 17,220-20,480 mm Hg × bpm. The functional capacity improved in Patient 1 8.07-8.91 METs, patient 2 1.91-4.01 METs, patient 3 3.45-6.39 METs, and patient 4 3.9-4.43 METs. The 6-min walking distance improved in patient 1 540-570 m and patient 2 345-405 m. The CCS class, bodily pain, and general health domain scores improved in all patients. CONCLUSION: ESMR therapy might be beneficial for indicated patients with CABG-SAP to improve ischemic response, functional capacity, and physical component of quality of life.

Superior Vena Cava Syndrome due to pericardial hematoma: A case report and mini-review of literature.

Superior vena cava syndrome is a life-threatening condition. Typically, the clinical presentations are gradual; hence, the diagnosis is often delayed until critical compression or obstruction has occurred. Pericardial hematoma is a rare condition that could occur after cardiac surgery. An asymptomatic, 25-year-old female, who underwent surgical atrial septal defect closure 5 days ago, was sent for routine echocardiography examination before discharge. An intrapericardiac hematoma was detected at the right atrium's free wall without any intracardiac hemodynamic consequences. The patient was discharged and planned for monthly evaluation. During follow-up, the intrapericardiac hematoma was expanding. In the third month's follow-up, the patient complained of shortness of breath, headaches, and coughs. Echocardiography evaluation revealed enlarged pericardial hematoma, which compressed the right atrium and superior vena cava orifice, without echo' sign of cardiac tamponade. Computed tomography scan revealed superior vena cava compression by the pericardial hematoma and appearance of the collateral vessel. The patient was diagnosed with superior vena cava syndrome and sent for surgical evacuation. Pericardial hematoma after cardiac surgery should be evaluated meticulously. Chronic expanding hematoma could cause superior vena cava syndrome, which is fatal. Early diagnosis and appropriate treatment are essential in managing this condition.

A case of endocarditis and spondylodiscitis associated with Mycobacterium tuberculosis.

Tuberculosis (TB) is a global health problem, in which the majority of cases occur in population-dense developing countries. Despite advances in various diagnostic TB modalities, extrapulmonary TB remains a challenge due to complexities related to its diagnostic approach. Hereby, we present a rare case of endocarditis and spondylodiscitis associated with Mycobacterium tuberculosis (MTB). This case report highlighted the challenges faced in diagnosing blood culture-negative infective endocarditis (BCNIE). We also emphasized the importance of considering MTB as etiology of BCNIE, particularly in endemic TB areas.

The Influence of Right Ventricular Pacing Location, Pacing Burden and Paced QRS Duration to Subclinical Left Ventricular Systolic Dysfunction as Shown by Global Longitudinal Strain Echocardiography.

BACKGROUND: Prolonged pacing of the right ventricle (RV) is associated with left ventricular (LV) systolic dysfunction. Several studies have shown that the RV pacing location, pacing burden (percentage), and paced QRS duration may affect LV systolic function. Subclinical LV dysfunction may occur early after implantation of a permanent pacemaker (PPM). Therefore, this study aims to detect early subclinical LV systolic dysfunction measured by global longitudinal strain (GLS) using speckle tracking echocardiography (STE) at one month after PPM implantation. METHODS: A single-center, prospective cohort study was conducted, and all patients indicated for PPM implantation with preserved LV systolic function were included. Data of RV pacing location (RV apical vs right ventricular outflow tract (RVOT), pacing burden (percentage) (≤40% vs >40%), and paced QRS duration (≤150 ms and >150 ms) were obtained. The change of GLS was also measured before and one month after PPM implantation (delta GLS). RESULTS: 37 patients were enrolled in this study, which demonstrated significant difference between GLS before (-20.30 SD 3.38) and after (-16.93 SD 3.47) PPM implantation (p=<0.001). There were no significant difference in delta GLS either between patients with RV pacing location on RV apical vs RVOT ((2.30 (0.00-10.50) vs 2.95(0.10-8.30), p=0.648) or between patient with paced QRS duration ≤150ms vs >150ms ((1.70 (0.30-8.30) vs 3.45 (0.0-10.5)), p=0.266). Meanwhile, there was a significant difference of delta GLS between patients with pacing burden ≤40% vs >40% (Mean 1.92 SD 1.37 vs 3.98 SD 3.04), p=0.007). Further analysis found that pacing burden only affected the delta GLS in group with apical RV pacing (≤40% (1.58 SD 0.59) vs > 40% (4.67 SD 3.47), p = 0.008) and did not affect the delta GLS in group with RVOT pacing (≤40% (2.32 SD 1.98) vs > 40% (3.29 SD 2.48), p = 0.446). CONCLUSION: The pacing parameter, particularly pacing burden > 40% may induce the subclinical LV systolic dysfunction after one month of pacemaker implantation as shown by decline of GLS,  especially when the RV pacing location was placed on apical.

Myocardial dissection complicating left sinus of Valsalva aneurysm in silent takayasu arteritis.

BACKGROUND: Myocardial dissection (MD) in a left sinus of Valsalva aneurysm (LSVA) is a rare condition that may lead to a fatal complication. Determining the MD etiology is challenging because of various possibilities ranging from congenital to acquired diseases. Here, we discuss an approach for determining the etiology of MD complicating LSVA in Takayasu arteritis (TA) and its treatment. CASE PRESENTATION: A 41-year-old man presented with dyspnea on heavy activities and a history of consciousness loss at the age of 24 years. He was diagnosed with dilated cardiomyopathy and MD complicating LSVA in TA based on combined clinical and pathognomonic diagnostic criteria of TA evaluated using vascular Doppler and computed tomography angiography of the aorta. The patient refused to undergo surgery and received an optimal dose of chronic heart failure therapy, a high-dose steroid, and azathioprine. The patient experienced some improvements in clinical condition, functional outcome, and inflammatory markers at 1-year follow-up. CONCLUSIONS: Clinical criteria and various imaging modalities may be used to determine the etiology of MD complicating LSVA in silent TA. As an alternative to surgery, the optimal medical treatment might result in a satisfactory outcome.

A fatal case of early prosthetic valve endocarditis caused by multidrug-resistant (MDR) - Sphingomonas paucimobilis.

Sphyngomonas paucimobilis (S. paucimobilis) is a low-pathogenicity, gram-negative bacilli (GNB) that are previously known as an opportunist microorganism. Recent studies have shown that S. paucimobilis is an emerging pathogen causing various infections. Multidrug-resistant GNB has emerged as a major clinical and therapeutic dilemma in various hospital-associated infections. Although rare, S. paucimobilis could be associated with infective endocarditis (IE). Prosthetic valve endocarditis (PVE) is the most severe type of IE, which has high mortality rates despite diagnostic and treatment advances. We report a fatal case of early PVE associated with multidrug-resistant (MDR) - S. paucimobilis complicated with perivalvular abscess, complete heart block, valve detachment, and septic arthritis.
