Abstract
Restenosis of the mitral valve after surgical commissurotomy is a recognized event that ocours over a varing period of time. time. Closed and open commissurotomy has been suggested to treat this recurrent pathology although the increasing risk of a second thoracotomy. Recently, balloon mitral valvuloplasty, a technique introduced in the eighties, has gained progressive acceptance because of its good ciinical and hemodynamic results. It carries less hazards and complications in ccmparison with the surgical techniques. To evaluate the efficacy and safety of balloon mitral valvuloplasty inpatients with mitral valve restenosis, sixty-three patients were studied. They were divided into two groups twenty patients had mitral valve restenosis after surgical commissurotomy or balloon valvuloplasty group I, and forty-three patients had mitral stenosis without prior interventions group II. Each patienl was subjected to clinical examination, twelve leads resting electrocadriography, transthoracic and transesophageal echocardiographic study and percutaneous transvenous balloon mitral - valvuloplasty using lnoue technique.
