Background and aim of the study: Residual or recurrent tricuspid regurgitat
ion (TR) has been reported after several types of surgical repair. The deve
lopment of late TR is an important complication of left heart surgery. The
results of De Vega annuloplasty were compared with those obtained after Car
pentier-Edwards ring (CE ring) annuloplasty in patients with secondary TR.
Methods: The records of 45 patients who underwent surgery for secondary TR
between January 1995 and July 2000 were reviewed retrospectively. Twenty-ei
ght patients underwent De Vega annuloplasty, and 17 had a CE ring annulopla
sty. The groups were similar with respect to associated cardiac lesions. No
significant preoperative differences were observed in NYHA functional clas
s, TR grade, and pulmonary artery pressure between the two groups.
Results: One CE patient died of left ventricular dysfunction after postoper
ative bleeding. The 28 De Vega patients and remaining 16 CE patients had an
uneventful recovery, and were discharged. Tricuspid ring size after repair
was similar between groups. Mean (+/- SD) follow up in the entire patient
cohort was 39 +/- 23 months (range: 6 to 75 months). TR recurrence was rate
d as grade II or III in 13 patients (45%) after De Vega annuloplasty, but w
as grade II or III in only one patient (6%) patient after CE ring annulopla
sty. There was a significant difference in TR recurrence between the groups
(p = 0.027), but no significant difference in NYHA class.
Conclusion: CE ring annuloplasty significantly decreased the recurrence of
TR; thus, CE ring annuloplasty is superior to De Vega annuloplasty in patie
nts with secondary TR.
