210 Echocardiographic factors determining immediate results of percutaneous mitral balloon commissurotomy

Percutaneous mitral valvuloplasty: the debate is there

“…The most widely acknowledged of these was the Massachusetts General Hospital (MGH) scoring system that includes scoring values for mitral valve leaflet thickness, mobility restriction, calcification and subvalvular affection (16). Although revered and time-honored, this scoring system has recently come under intense scrutiny, chiefly after an emerging body of literature emphasized the key role of commissural calcification and subvalvular affection in determining a 'poor' procedural outcome (17,18). More recently, a novel scoring system was suggested based only on these two parameters, and better predicted immediate outcome following the procedure, as compared with the standard MGH score, in a late-breaking small randomized study (19).…”
