Slide3Background The latest generation Trifecta valves, Trifecta GT (St. Jude Medical Inc., St. Paul, MN), are designed to have improved hemodynamics: Incorporate several unique design features Objective:
Evaluate early and intermediate outcomes and hemodynamics of the latest generation Trifecta valve, implanted using right anterior mini-thoracotomy.
Slide4Methods Single center, retrospective study:January 2016 to January 2019175 patients undergoing isolated mini-AVR with Trifecta GT valves through right anterior mini-thoracotomyExclusions:
Conversion to full median sternotomy Any concomitant procedure Non-survival during the index admission Analyses addressed implantation safety, 30 day and intermediate-term survival and hemodynamic performance of the valves
Slide5ResultsFollow up duration: 6 months to 3 yearsEarly (<30 day) and late mortality rate of 1.1% (n=2) and 5.1% (n=9), respectivelyEarly thromboembolic events:
7 (4%) patientsReoperations due to bleeding: 11 (6.2%) patientsNo valve explants5Table 1. Preoperative and postoperative echocardiographic data
Slide6Conclusions
This is the largest series reporting on outcomes of the latest generation Trifecta valve implanted using right anterior mini-thoracotomy. Our results demonstrate that this valve can be safely implanted via a minimally invasive approach with excellent early and intermediate outcomes and hemodynamic performance.
