Аннотация
Kay's mitral valve repair was performed in six consecutive patients with symptomatic mitral regurgitation due to ruptured chordae tendineae of the posterior leaflet. All patients including one with mild residual murmur showed a marked decrease in the heart size and significant clinical improvement. Postoperative hemodynamic studies, performed in four patients, showed restoration of normal or near-normal dynamics. The medium-term follow-up, 15 to 30 months after the operation, revealed continuing asymptomatic states in all. The function of the repaired valves was significantly better than that of the Hancock mitral bioprostheses. The advantages of this procedure compared with mitral valve replacement for the same condition were stressed.
