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

Abstract

BACKGROUND: Percutaneous Transluminal Mitral Commissurotomy (PTMC) is the treatment of
choice for mitral stenosis. Patients with valvular calcification, thickened fibrotic leaflets and subvalvular
fusion have adverse immediate outcomes of PTMC.
OBJECTIVE: To determine the frequency of immediate outcomes of percutaneous transluminal mitral
commissurotomy in patients of mitral stenosis.
This is descriptive cross sectional study conducted in the Cardiology Unit Govt. Lady Reading Hospital
Peshawar 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 in
Cardiology Unit, Lady Reading Hospital, Khyber Teaching Hospital and Hayat Abad Medical Complex
Peshawar were included in the study. After performing PTMC according to the standard protocol, data
regarding failure of the procedure, severe mitral regurgitation, cardiac tamponade, thromboembolism
and in-hospital death was recorded.
RESULTS: Out of 577 patients, 220 (38.13%) were males and 357 (61.87%) were females. The mean
age 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 of
mitral stenosis with favorable mitral valve morphology.
