Impact of Preimplantation Tricuspid Regurgitation on Long Term Outcome in Patients Undergoing LVAD Implantation in the Era of Rotary Blood Pumps

Outcomes in patients who underwent a concomitant tricuspid valve procedure during left ventricular assist device implantation

BACKGROUND

Study findings have been inconsistent regarding whether a concomitant tricuspid valve replacement or repair performed concurrently with continuous-flow left ventricular assist device (CF-LVAD) implantation has additive clinical benefit in patients with severe tricuspid valve regurgitation (TR).

AIM OF STUDY

To determine the effect of performing a concomitant tricuspid valve procedure (TVP) at the time of CF-LVAD implantation on patient outcomes.

METHODS

We retrospectively reviewed our single-institution experience in 526 patients who underwent primary implantation of a CF-LVAD between November 2003 and March 2016. We identified 59 (11.2%) patients who had severe TR at the time of implantation and analyzed the effect of performing a concomitant TVP at the time of CF-LVAD implantation on the rate of survival, incidence of postoperative right heart failure (RHF), recurrence of TR, and incidence of 30-day readmission.

RESULTS

We did not observe a significant difference in the overall survival rate (P = .51), incidence of postoperative RHF (P = .26), or recurrence of TR (P = .73) between patients with severe TR who underwent a TVP and those who did not at the time of CF-LVAD implantation. However, the incidence of 30-day readmission was significantly lower in patients who underwent a TVP than in those who did not (P = .002).

CONCLUSIONS

Performing a concomitant TVP at the time of CF-LVAD implantation did not improve patient outcomes but reduced the incidence of 30-day readmission.
