Comparison and outcome of commissurotomy by metallic valvotome and balloon commissurotomy.

ABSTRACT

The purpose of this study was to compare the echocardiographic outcome of percutaneous transvenous metallic mitral commissurotomy (PMMC) and Percutaneous transvenous balloon mitral commissurotomy (PTMC). This prospective comparative study was carried out during the period of January 1999 to June 2000 in the department of Cardiology, National Institute of cardiovascular diseases (NICVD) and national heart foundation hospital, Dhaka Bangladesh. Two dimension, M-mode, spectral and colour Doppler studies were done to all patient of mitral stenosis both before and after PMMC and PTMC. The increased in mitral valve area in PMMC was statistically significant than PTMC. (P<0.047).
