ABSTRACT
Out of 1184 consecutive cases of rheumatic mitral stenosis treated surgically by closed mitral commissurotomy (CMC) at NRS Medical College and Hospital, Calcutta, 20 (1.68%) were mitral valve restenosis. Twelve cases (60%) were females, The median age was 32 years. Duration between the first operation and reappearance of symptoms varied with a mean of 8 years. The previous operations were digital dilatation and instrumental dilatation in 6 and 14 cases respectively. History of thromboembolism was present in 4 cases. On echocardiography, calcification of the mitral valve was present in 2 cases, left atrial clot in 4 cases, associated mild to moderate mitral regurgitation in 6 cases and mild aortic regurgitation in 4 cases. All cases presented with New York Heart Association (NYHA) III and IV symptoms. Critical stenosis (mitral valve orifice less than 0.5 cm2) was present in 12 cases. Re-do CMC was undertaken in all cases with Tubb's dilator. Median operating time was 2.5 hours. Satisfactory split was achieved in 13 cases. One patient died during surgery. Four cases having less than satisfactory split were asymptomatic on follow-up. In one case no split was possible and in another, gross mitral regurgitation was noted postoperatively. These 2 cases had to undergo open heart surgery. It is concluded that re-do CMC is a feasible and suitable alternative in mitral restenosis even in the presence of complications.
