Correction of significant tricuspid regurgitation (TR) at the time of continuous-flow (CF) left ventricular assist device (LVAD) implantation has been shown to be beneficial in several recently published studies. The most common technique is ring annuloplasty followed by valve replacement. Our center has primarily used the De Vega annuloplasty, and the durability of this repair is the focus of this study.Methods
This was a retrospective review of 35 consecutive patients who underwent CF LVAD implantation and De Vega tricuspid valve annuloplasty (TVA) for severe TR and were alive at 1 year. Echocardiograms were obtained preoperatively, intraoperatively, at discharge, and at 1 year after operation.Results
The TR in 32 of 35 patients (91.4%, group A) improved from severe preoperatively to insignificant at the time of discharge after De Vega TVA, and 3 patients (8.6%, group B) had moderate residual TR. At 1-year follow-up, 29 of 32 (90.6%) patients in group A had insignificant TR, 2 (6.3%) had moderate TR, and 1 (3.1%) had severe TR. In group B, 2 of 3 patients had no progression of their moderate TR at 1 year and 1 had severe TR. Overall, 2 of 35 (5.7%) patients had severe TR at 1 year after De Vega TVA and LVAD implantation.Conclusions
We conclude from this consecutive cohort of patients undergoing CF LVAD implantation and De Vega TVA that this technique is very durable at 1 year and has the advantages of a shorter operative time relative to ring annuloplasty and decreased cost because a prosthetic implant is not used.
