Abstract
Rheumatic mitral stenosis is one of the commonest valvular disease in Egypt and other developed countries.
Mitral commissurotomy has been used successfully for many years to treat patients with mitral stenosis.
This study aimed to compare and evaluate the results and the effects of two techniques through analysis of two groups of patients who underwent balloon mitral commissurotomy (BMC), and open mitral commissurotomy (OMC) respectively.
These patients were, from the clinical and morphological point of view, optimal for both balloon and open commissurotomy procedures as demonstrated by a mean age of < 30 years, absence of mitral valve calcification on 2D echo-cardiography and an echo-cardiographic score
< 8 in all patients.
The reliability of the echo-cardiographic score of predicting results of commissurotomy is not optimal because results of commissurotomy are also related to other factors, such as the age and sex of the patients ,the presence of atrial fibrillation, mitral regurgitation and pulmonary hypertension,a history of previous surgical commissurotomy and the severity of mitral stenosis.
Included 30 patients with rheumatic mitral stenosis who underwent percutaneous balloon mitral commissurotomy. This technique offered excellent results in 83.3% and good results in 13.3%of the patients with symptomatic and haemodynamic improvements including increase of mitral valve area , decrease in diastolic pressure gradient across the mitral valve and decrease of pulmonary artery pressure. Poor results in one patient and there was no mortality.
