R Rheumatic mitral stenosis in Children: more accelerated course in sub-Saharan Patients
Background: Mitral stenosis, one of the grave consequences of rheumatic heart disease, was generally considered to take decades to evolve. However, several studies from the developing countries have shown that mitral stenosis follows a different course from that seen in the developed countries. This study reports the prevalence, severity and common complications of mitral stenosis in the first and early second decades of life among children referred to a tertiary center for intervention. Methods: Medical records of 365 patients aged less than 16 and diagnosed with rheumatic heart disease were reviewed. Mitral stenosis was graded as severe (mitral valve area < 1.0 cm 2 ), moderate (mitral valve area 1.0-1.5 cm 2 ) and mild (mitral valve area > 1.5 cm 2 ). Results: Mean age at diagnosis was 10.1 ± 2.5 (range 3-15) years. Of the 365 patients, 126 (34.5%) were found to have mitral stenosis by echocardiographic criteria. Among children between 6-10 years, the prevalence of mitral stenosis was 26.5%. Mean mitral valve area (n = 126) was 1.1 ± 0.5 cm 2 (range 0.4-2.0 cm 2 ). Pure mitral stenosis was present in 35 children. Overall, multi-valvular involvement was present in 330 (90.4%). NYHA functional class was II in 76% and class III or IV in 22%. Only 25% of patients remember having symptoms of acute rheumatic fever. Complications at the time of referral include 16 cases of atrial fibrillation, 8 cases of spontaneous echo contrast in the left atrium, 2 cases of left atrial thrombus, 4 cases of thrombo-embolic events, 2 cases of septic emboli and 3 cases of airway compression by a giant left atrium. Conclusion: Rheumatic mitral stenosis is common in the first and early second decades of life in Ethiopia. The course appeared to be accelerated resulting in complications and disability early in life. Echocardiography-based screening programs are needed to estimate the prevalence and to provide support for strengthening primary and secondary prevention programs.

Risk Stratification and Mortality in Mitral Stenosis Patients
ACI (Acta Cardiologia Indonesiana)
Background: Rheumatic mitral stenosis is the most common valvular abnormalities found in developing countries. Mortality risk in those populations was poorly investigated. In addition, hemodynamic, morphological, and mechanical factors that influence or predict outcome of rheumatic mitral stenosis have not been identified. Aims: To determine predictive factors affecting outcome in rheumatic mitral stenosis patients. Method: This retrospective cohort study was conducted at the National General Hospital Dr. Sardjito, Yogyakarta, Indonesia. The study recruited patients from the Valvular Heart Disease Registry from May 2014 to November 2020. New York Heart Association (NYHA) functional classification, invasive or surgical treatment, and incidence of death were recorded. The baseline rhythm from electrocardiography (ECG) was categorized as sinus rhythm and atrial fibrillation or atrial flutter. Based on the findings of trans thoracal echocardiography (TTE), subjects who had moderate to s...

Background and aims: Rheumatic heart disease is one of the most common cause for heart failure and associated mortalities/morbidities in the young population in developing countries like Nepal imparting huge familial, social and manpower burden. Materials and methods: This is a hospital based descriptive cross-sectional study during June 2014 to April 2016 over a period of 22 months at College of Medical Sciences-Bharatpur including 235 patients with clinical and/ or echocardiographic evidence of definite rheumatic heart disease. Results: The age of the patients ranged from 7 to 76 years with mean age 39.82 ± 4.2 years with female preponderance (F:M = 2.1:1) (p b 0.01). Majority of the rheumatic heart disease patients belonged to 30-44 years (28.78%) followed by 15-29 years (25.75%) and 45-59 years (25.00%). Majority belonged to the low socioeconomic status (60.60%) (p b 0.05). The predominantly involved isolated valve was mitral in 110 patients (46.80%) followed by isolated aortic valve in 22 patients (9.36%) and 79 (33.62%) had dual valvular involvement. The common rheumatic valvular lesions were pure mitral stenosis in 32 (13.61%), isolated mitral regurgitation in 58 (24.68%), combined mitral stenosis/regurgitation in 36 (15.32%), combined mitral/aortic regurgitation in 23 (9.78%) and combined aortic stenosis/regurgitation in 18 (7.66%) patients with few overlappings. The common complications encountered were heart failure in 90 (38.30%) and arrhythmias in 124 (51.00%) patients.130 patients (55.32%) received injectable benzathine penicillin whereas 45 patients (19.15%) preferred oral penicillin V. Surgical intervention was done in 54 (22.97%) patients. 12 (5.10%) expired in the CCU during the course of treatment. Conclusion: RHD is a leading cause of heart failure among young populations with requirement of prolonged duration of medical treatment and many of them requiring surgery.

Background: Rheumatic mitral stenosis (RMS) is the cause of mitral valve disease commonly found in developing countries. Determining severity of RMS is very important, related with prognosis and management of the disease. Current echocardiography methods have advantages and disadvantages in determining the severity of RMS. Posterior to anterior mitral valve leaflets length ratio (PMVL/ AMVL ratio) was proposed to be one of the semi-quantitative measurement which offered a simple, easy and accurate method in determining the severity of RMS. The aim of this study was to see the association of posterior to anterior mitral valve leaflets length ratio with severity of rheumatic mitral stenosis. Methods: This was a cross-sectional descriptive analytic study. The subjects were all patients with rheumatic mitral stenosis who underwent echocardiography examination to measure the PMVL/AMVL ratio as well as determining the severity based on mitral valve area (MVA) planimetry. One-way ANOVA analytic test was used to assess the association of ratio PMVL/AMVL and severity of the RMS. Results: Of 71 patients included in this study, there were 19 mild RMS, 19 moderate RMS and 33 severe RMS patients. Majority of the subjects were female with age range from 38 to 43 years and have atrial fibrillation. From echocardiography examination, the mean EF +/-55% with increased LAVI and SPAP according to the severity of the RMS (LAVI; 44±1.3 vs. 55±1.5 vs. 74±1.7 ml/m 2 SPAP; 29±1.2 vs. 46±9.0 vs. 68±1.4 mmHg). There was a significant difference in the length of PMVL in mild, moderate and severe RMS (28±5.6 vs. 22±4.0 vs. 17±5.2 mm; p<0.001), but no significant difference in the length of AMVL (33±5.5 vs 33±5.4 vs 32±5.1mm; p=0.93) respectively. The PMVL/AMVL ratio had statistically significant association with severity of RMS (p<0.001). Conclusion: The PMVL/AMVL ratio is significantly associated with severity of RMS.

Anatomical and Hemodynamic Evaluation of Mitral Stenosis Patients with Echocardiography
Bioscientia Medicina : Journal of Biomedicine and Translational Research
Mitral stenosis (MS) is the most common valvular heart disease encountered in developing countries. The cause of MS is almost always chronic rheumatic heart disease. Echocardiography is the single most important diagnostic tool in the evaluation of MS. The objectives are to confirm the etiology, to assess the severity of stenosis, to recommend the type and timing of intervention, to assess other valvular lesions, presence of thrombus, and vegetation. According to current guidelines and recommendations for clinical practice, the severity of MS should not be defined by a single value but rather be assessed by a multimodality approach that determines valve areas, mean Doppler gradients, and pulmonary arterial pressures. The European Society of Echocardiography/American Society of Echocardiography (EAE/ASE) recommendations of measurement method for clinical practice were categorized into three level of recommendations. Mitral valve area (MVA) can be assessed by planimetry using either 2...

Introduction: Rheumatic heart disease (RHD) remains a major public health issue affecting children and young adults in developing countries. This study aimed to evaluate the clinical characteristics, management, and reactivation of RHD among children and young adults. Patients and Methods: This was a hospital-based retrospective study conducted at the National Cardiovascular Center Harapan Kita, Indonesia; we retrieved relevant data from patients diagnosed with RHD between 2012 and 2018. Results: Two hundred and seventy-nine patients were diagnosed with rheumatic heart disease, of whom 108 were children (mean age of 12.02 ± 3.36 years) and 171 were young adults (mean age was 24.9 ± 3.84). RHD was more common in female than in male young adults (1.5:1). Hospitalization due to RHD complications such as congestive heart failure was seen in 11.11% of cases in children, while pulmonary hypertension was present in 19.95% young adult cases. Reactivation of RHD occurred in 17.2% (48/279) cases, significantly in children (p < 0.001). Overall, the mitral valve (either isolated or combined) was the organ most affected in children (39.13%) and young adults (44.81%). Isolated mitral regurgitation was more common in children (13/21, 61.9%), while isolated mitral stenosis was more common in young adults (19/47, 40.42%). There was a high rate of rheumatic tricuspid valve disease in all populations (193/279, 69.17%) and reported involvement of pulmonary regurgitation (46/279, 16.48%). Multivalve lesions were more common than single lesions in both groups, with a combination of mitral and tricuspid regurgitation the predominant type in children (32/43, 74.41%) and mixed mitral lesion and tricuspid regurgitation in young adults (22/72, 30.56%). We observed a significant occurrence of quadrivalve lesions in children (p = 0.039). Valve repair was more common in children (49.07%) and replacement in young adults (32.16%), with low in-hospital mortality. Compliance with secondary prophylaxis was a significant challenge. Conclusion: Chronic RHD often presented with complications of the disease or reactivation of rheumatic fever (RF). Inadequate treatment of RF/RHD leads to extensive valvular damage and consequent disabilities. Efforts toward active early diagnosis and prompt treatment of RF/RHD and effective preventive measures are essential.
