ABSTRACT
Assessment of value of exercise echocardiography using in patients with rheumatic moderate mitral valve stenosis in interventional decision making [percutenous balloon mitral valvuloplasty]. 30 patients with moderate mitral stenosis were participated in the study. All patients were subjected to exercise echocardiography and were divided into two groups. Group I: 20 patients with good exercise tolerance and group II: 10 patients with poor exercise tolerance and mitral valvuloplasty was done, and then reevaluated with exercise echocardiography one month after valvuloplasty. In group [I] mean pressure gradient across mitral valve at peak of exercise was ranged between 12 and 16 mmHg with mean of 134.78 +/- 1.33 mmHg, while in group[II] mean pressure gradient across mitral valve at peak of exercise was ranged between 17 and 20 mmHg with mean of 18.30 +/- 1.25 mmHg. In group [I] pulmonary artery pressure at peak of exercise ranged between 25 and 40 mmHg with mean of 30.00 +/- 5.38 mmHg, while in group [II] it was ranged between 35 and 40 mmHg with mean of 39.00 +/- mmHg at peak of exercise. All members of group II had subvalvular affection [high score] and 50% of them had high score for calcification with poor exercise tolerance while non of group I had subvalvular affection and only 10% of them had law calcific score]. Exercise echocardiography plays an important role in evaluating true symptomatic patients and assesses the hemodynamic severity in patients with moderate mitral stenosis
