Technical considerations and intermediate-term results with modified DeVega tricuspid annuloplasty.
Because of unsatisfactory long-term results with current DeVega tricuspid annuloplasty, 43 patients with secondary tricuspid regurgitation associated with mitral disease were treated with a modified DeVega operation. This procedure continues the suture line to the tendon of Todaro, resulting in almost circumferential traction of the tricuspid annulus. The suture is tied securely around a 29-mm or 31-mm (for women and men, respectively) ball-shaped obturator. Atrioventricular block was not observed. One patient died during the early postoperative period. During a mean(s.d.) follow-up of 5.0(2.0) years, one patient died from causes unrelated to tricuspid regurgitation 2 years after surgery. The mean(s.d.) functional class (New York Heart Association) was 3.1(0.5) on admission and improved to 1.2(0.4) at the end of follow-up. The mean(s.d.) cardiothoracic ratio improved from 67(6) to 60(5)% at 1 month after operation and was 59(5)% at the final examination. Preoperative Doppler echocardiography revealed a mean(s.d.) regurgitation grade of 2.7(0.7). (Grades 1-4 are equivalent to mild, moderate, severe and massive regurgitation, respectively.) At 1 month, regurgitation was corrected almost completely in all patients (grade 0.2(0.4)) and remained significantly improved at follow-up (grade 0.5(0.6)). The actuarial freedom rate at 5 years for moderate or severe regurgitation (> grade 2) was 93%. This modification of the DeVega technique substantially improved early and late tricuspid valve competence.
