Abstract : Background Percutaneous transvenous mitral commissurotomy (PTMC) is a valid alternative to surgical therapy in selected patients with mitral stenosis. Juvenile mitral stenosis (JMS) varies uniquely from adult rheumatic heart disease (RHD). We aimed to evaluate the efficacy of PTMC in JMS patients. Methods It was a single centre, retrospective study conducted between July 2013 to June 2015 in Shahid Gangalal National Heart Centre, Kathmandu, Nepal. Medical records of all consecutive patients aged less than 21 years who underwent PTMC were included. Mitral valve area (MVA), left atrial pressure and mitral regurgitation (MR) were compared pre and post procedure. Results During the study period 131 JMS patients underwent PTMC. Seventy (53.4%) were female and 61 (46.6%) were male. Among the 131 patients, 40 (30.5%) patients were below the age of 15 years. Patient age ranged between 9 to 20 years with the mean of 16.3±2.9 years. Electrocardiography (ECG) findings were normal sinus rhythm in 115 (87.7%) patients and atrial fibrillation in 16 (12.3%) patients. Left atrial size ranged from 2.9 to 6.1 cm with the mean of 4.5±0.6 cm. The mean MVA increased from 0.8±0.1 cm2 to 1.6±0.2 following PTMC. Mean left atrial pressure decreased from their pre-PTMC state of 27.5±8.6 to 14.1±5.8 mmHg. Successful results were observed in 115 (87.7%) patients. Suboptimal MVA <1.5 cm2 in 11 (8.4%) patients and post-procedure MR of more than moderate MR in 5 (3.8%) patients was the reason for unsuccessful PTMC. Conclusions PTMC in JMS is safe and effective.
