What are the complication rates and predictors of early mortality associated with percutaneous balloon mitral commissurotomy in patients with rheumatic mitral stenosis?
Percutaneous balloon mitral commissurotomy is effective but carries a 12% serious complication rate and 3.3% 30-day mortality, with outcomes strongly influenced by baseline valve morphology and center volume.
A 1992 study studied this question.
