Abstract

Background-Percutaneous balloon mitral valvotomy (BMV) has been accepted as an alternative to surgical mitral commissurotomy in the treatment of patients with symptomatic rheumatic mitral stenosis. Despite the worldwide use of the BMV technique, no studies have been hitherto designed to assess the outcome of the patients undergoing BMV in Iran. The present study reports the outcome of 3138 BMV procedures at Shaheed Rajaei Cardiovascular, Medical and Research Center during a 15-year time period.
Methods-A total of 2531 patients underwent 3138 BMV procedures at Shaheed Rajaei Cardiovascular, Medical and Research Center between 1992 and 2006. Seventy-three percent (2278) of the cases were followed for 48±41 months.
Results-Recurrent stenosis in 802 (25.8%), mitral valve replacement (MVR) in 213 (6.9%), immediate good result in 3110 (99.1%), and successful outcome in 2000 (72.9%) cases were the outcome of the BMV procedures in the current study.
Conclusion-Concordant to the similar studies, we concluded that BMV produces a good clinical outcome in a high percentage of patients.
The recent study demonstrated that the successful outcome of BMV was multi factorial and the selection ofpatients with rheumatic mitral stenosis is recommended to be based on both anatomic and clinical characteristics of the individuals. The procedure-related variables must also be considered in order to predict the outcome.
