Recent developments in balloon valvuloplasty techniques.

The long-term outcome after mitral valvuloplasty is excellent and compares well with surgical treatment of mitral stenosis. Compared with the double balloon technique, the Inoue method is technically easier and may reduce acute complications without any adverse effect on long-term outcomes. Excellent long-term outcome is also seen after balloon valvuloplasty of aortic stenosis in the young and in pulmonary stenosis at all ages. Finally, although balloon aortic valvuloplasty in the elderly may not change the terrible prognosis of such patients, it does improve functional status and is a useful bridge to surgery in selected patients.
