Implication
Supports multifactorial risk stratification for immediate outcomes after percutaneous mitral commissurotomy; hypothesis-generating and should not yet change practice.
Structured PICO
What are the predictive factors for good immediate results following percutaneous mitral commissurotomy?
P
Population
1,514 patients undergoing percutaneous mitral commissurotomy, mean age 45 +/- 15 years. Echocardiographic characteristics: 16% pliable valves and mild chordal thickening, 59% extensive subvalvular disease, 25% calcified valves.
I
Intervention
Percutaneous mitral commissurotomy (performed with a single balloon in 30 patients, a double balloon in 586, and the Inoue balloon in 876)
O
Outcome
Good immediate results defined as a valve area >= 1.5 cm2 with mitral regurgitation Sellers' grade <= 2surrogate
A multifactorial predictive model incorporating age, echocardiographic characteristics, valve area, and balloon dilating area can help predict the immediate success of percutaneous mitral commissurotomy to improve patient selection.
