IMMEDIATE OUTCOMES OF PERCUTANEOUS TRANSLUMINAL MITRAL COMMISSUROTOMY IN PATIENTS OF MITRAL STENOSIS

BACKGROUND: Percutaneous Transluminal Mitral Commissurotomy (PTMC) is the treatment ofchoice for mitral stenosis. Patients with valvular calcification, thickened fibrotic leaflets and subvalvularfusion have adverse immediate outcomes of PTMC.OBJECTIVE: To determine the frequency of immediate outcomes of percutaneous transluminal mitralcommissurotomy in patients of mitral stenosis.This is descriptive cross sectional study conducted in the Cardiology Unit Govt. Lady Reading HospitalPeshawar from Jan, 2008- Feb, 2012, five hundreds and seventy seven patients of mitral stenosis.METHODS: Mitral patients with or without pre existing mild mitral regurgitation admitted inCardiology Unit, Lady Reading Hospital, Khyber Teaching Hospital and Hayat Abad Medical ComplexPeshawar were included in the study. After performing PTMC according to the standard protocol, dataregarding failure of the procedure, severe mitral regurgitation, cardiac tamponade, thromboembolismand in-hospital death was recorded.RESULTS: Out of 577 patients, 220 (38.13%) were males and 357 (61.87%) were females. The meanage of the patients was 31.96±10.01 years. Failure of the procedure of PTMC was found in 38 (7%)patients, severe mitral regurgitation in 27 (5%) patients, cardiac tamponade in 1 (0.17%) patients,thromboembolism in 3 (0.52%) patients and In-hospital death occurred in 5 (0.867%) patients.CONCLUSION: PTMC is a safe and effective procedure with good immediate outcomes in patients ofmitral stenosis with favorable mitral valve morphology.KEY WORDS: Mitral stenosis, PTMC, BMV, Outcomes of PTMC.
