ABSTRACT
BACKGROUND AND OBJECTIVES:
Percutaneous mitral balloon valvuloplotomy (PMV) is a safe and effective procedure for the treatment of mitral stenosis (MS); however, its long-term results according to the severity of MS remain unknown. The aim of this study was to compare the long-term results of PMV between moderate and severe MS. SUBJECTS ANDMETHODS:
The immediate and long-term outcomes of 786 patients (198 male, mean age; 43 years) who underwent PMV at a single referral center, between 1988 and 2000, were analyzed. The clinical and echocardiographic data were compared between moderate (n=357) and severe MS (n=429).RESULTS:
Optimal results were gained in 618 (79%) patients, including 80 and 76% moderate and severe MS cases, respectively (p=0.13). Acute complications occurred in 85 patients (11%), but without significant difference between the two groups. After a mean follow-up period of 94 months (range, 6 to 210 month), the 5 year event-free survival rate was better in moderate (88%) than in severe MS (79%), but the 10 year event-free survival rates were no different (65% vs. 65%). Independent predictors for better prognosis were a lower echo score ( or =1.7 cm2)(p=0.002, HR=0.65), less mitral regurgitation (CONCLUSION:
The immediate and long-term outcomes of PMV for moderate MS were no better after 9 years than those for severe MS. Therefore, PMV for moderate MS should be considered in selected cases with a favorable MV morphology.
