Abstract
Background: Mitral stenosis (MS) is the most common valve disease in developing countries and there
are many ways to deal with this condition. The aim of this study was to evaluate the immediate results of
percutaneous transvenous mitral commissurotomy (PTMC) in patients with severe symptomatic
rheumatic mitral stenosis.
Patients and Methods: From May 2006 to August 2007, 58 patients (17 male, 41 female) with age range
(16-57) years, underwent PTMC in Ibn AL- Bitar Hospital for Cardiac Surgery. All the patients were
symptomatic, their MVA 1.5 cm2 with NYHA class II-IV. Clinical evaluation and echocardiographic
examination were carried out before and after PTMC, mitral valve structures were assessed using Wilkins
score. The procedure was performed under local anesthesia, using the step-wise Inoue balloon technique
with the antegrade transvenous approach.
Results: The procedure was successful in 51(88%) of the patients and unsuccessful in the remaining
7(12%) patients. Successful result was defined as post procedure mitral valve area ( MVA) 1.5 cm² as
assessed by echocardiography and no mitral regurgitation (MR)>2 according to sellers classification.
Mitral valve area increased from 0.93 ±0.2 to 1.84±0.2 cm² after the procedure (P<0.001) as measured by
echocardiography. Severe MR was observed in 1(1.7%) patients, while new mild - moderate MR have
been detected in 9(17.6%) patients. Symptomatic improvement was seen in all patients who underwent
successful PTMC .There where no procedure related deaths, temponade or the need for emergent mitral
valve replacement.
Conclusion: percutaneous transvenous mitral commissurotomy by Inoue balloon technique is safe and
effective procedure for patients with severe and symptomatic rheumatic MS. The ideal candidate are
those patients with pliable valve ,but still most of patients with relatively high Wilkins echo score can get
considerable benefit.
