 note = {DeVega's tricuspid annuloplasty has become known as a useful surgical procedure for secondary tricuspid regurgitation. However, reportedly mild to moderate tricuspid regurgitation was observed late after surgery in some patients with left ventricular dysfuction or pulmonary hypertension. Semicircular annuloplastic sutures torn from the tricuspid annular ring are considered to be one of the probable causes in such cases. Therefore, we propose a modification of DeVega's tricuspid annuloplasty, in which we add buttressed sutures around semicircular buried sutures. Among 26 patients who showed moderate or severe tricuspid regurgitation associated with mitral valve diseases between July 1992 and September 1994, this technique was applied successfully in six. All patients had a +3 or +4 tricuspid regurgitation associated with severe mitral valve lesion, chronic atrial fibrillation and moderate cardiomegaly. Late postoperative echocardiographic examination revealed 0 or +1 regurgitation in all patients. This procedure is simple, safe and may be useful for preventing semicircular sutures torn from the tricuspid annular ring in the late postoperative stage.},
