IMMEDIATE OUTCOMES OF PERCUTANEOUS TRANSVENOUS MITRAL COMMISUROTOMY IN PATIENTS OF RHEUMATIC MITRAL STENOSIS

Abstract

Objective: To determine the immediate outcome of PTMC in patients ofRheumatic Mitral stenosis.

Methodology: This cross sectional study was conducted from 1st January 2011to 31st December 2016, at Department of Cardiology, Lady Reading Hospital,Peshawar. Patients with severe MS fulfilling the inclusion and exclusion criteriawere enrolled in the study. Detailed history and examination was done followedby transthoracic and transesophageal echocardiography. PTMC was performed.Pre and post-PTMC echocardiographic parameters were recorded. Post PTMCcomplications like moderate to severe mitral regurgitation, stroke, pericardialeffusion, new onset arrhythmias and death within 24 hours were also recorded .P<0.05 was taken as significant.

Results: Total of 300 patients with mean age of 26.26 ± 11.54 years wereenrolled, of which 78 (26%) were males. Mean MVA pre-PTMC was 0.96 ± 0.902 2 cm , dilated successfully to 1.81 ± 0.48 cm (p = 0.000). Immediatecomplications like moderate MR (30%), severe MR (2%) , CVA (6%), pericardialeffusion (0.33%), new onset arrhythmias (8% ) and death (4% ) were observed.

Conclusion: Although complications are observed during PTMC but it is a safeand effective procedure in patients of rheumatic mitral stenosis with suitablevalve morphology.
