This study is designed to test whether percutaneous balloon mitral valvuloplasty (PBMV) is effective for rheumatic mitral stenosis in Chinese patients with moderate to severe mitral regurgitation. Fifty-six patients with rheumatic mitral valve stenosis were divided into the mild, moderate, and severe regurgitation groups. Cardiac ultrasonography was measured before and 1 to 2 days after PBMV. Following PBMV, the mitral orifice was enlarged, and the left atrial diameter was reduced in the 3 patient groups. The enlargement of the mitral orifice in the mild regurgitation group was greater than that observed in the moderate and severe regurgitation groups. The size of the regurgitation area increased in the mild regurgitation group and decreased in the moderate and severe regurgitation groups, with the decrease in the severe regurgitation group being greater than that in the moderate regurgitation group. Therefore, PBMV is effective for treating rheumatic mitral stenosis in Chinese patients with mild to severe mitral regurgitation.
