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

: 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.
