Aims and Methods: Clinical and echocardiographic data of 547 consecutive patients (mean age, 31.5 years) undergoing mitral balloon valvuloplasty with follow-up of 1.5-19 years, were analyzed. Immediately after valvuloplasty, mitral valve area increased significantly from 0.92 ± 0.17 to 1.95 ± 0.29 cm2. Restenosis occurred in 169 (31%) patients; it was less common (20%) in those with a mitral echocardiographic score<= 8. Actuarial freedom from restenosis at 10, 15, and 19 years was 78% ± 2%, 52% ± 3%, and 26 ± 4%, respectively, and significantly higher in patients with echocardiographic scores<= 8: 88% ± 2%, 67% ± 4%, and 40% ± 6%, respectively. Event-free survival at 10, 15, and 19 years was 88% ± 2%, 60% ± 4%, and 28% ± 7%, respectively, and significantly higher in patients with echocardiographic scores 8 and post-procedure valve area<= 1.8 as predictors of restenosis, and echocardiographic score>8 and preexisting atrial fibrillation as predictors of combined events. Comparison with surgical series will be discussed. Conclusion MBV provides excellent long-term results for up to 19 years, the long-term outcome following MBV can be predicted from baseline clinical and valvular characteristics
