Background: Trifecta™ is an externally wrapped bovine pericardial aortic valve with a favorable hemodynamic performance and acceptable rate of freedom from structural valve degeneration. However, recent reports of early Trifecta valve failure question its durability. Rheumatic valve disease in middle age population is predominant, there is no data on the Trifecta performance, durability or safety available worldwide over the middle age population, as well as there is no previous reports from Middle East region. We report on mid-term clinical and hemodynamic performance of Trifecta valve in middle age population with small aortic annuls, a single centre report. Methods: A retrospective study of all patients who underwent Trifecta™ SAVR between June 2014 and December 2019 at cardiac center in Riyadh, Saudi Arabia. Haemodynamic performance was analysed by longitudinal Doppler echocardiography. Results: During a 5.5-year period, a total of 24 patients underwent SAVR with Trifecta™ valves at our heart centre. Patients had a median age of 47.1 years (IQR=37) and male:female ratio of 1:1. Patients had a median EuroScoreII of 2 (IQR=1). The 19 mm valve was the most frequently used (29.2%) followed by the 21 mm and 23 mm (both 25.0%). Concomitant procedure was (54.2%). All patients survived their operations and most (87.0%) had their symptoms relieved. A 30-day mortality rate of 4.2%. Patients were followed up for a median of 58.5 months (IQR= 38), during which 8.3% required re interventions, giving an overall freedom from re-intervention of 91.7%. The re-intervention after valve implantation was recorded in two (8.3%). These re-interventions were performed 3 years post initial surgery and were due to structural valve deterioration (SVD). The mean gradient reduced significantly from 43.6 ±23.9 mmHg (median= 41, IQR=21) at baseline to 13.0 ±7.4 mmHg (median= 11, IQR=5) one-week post intervention (pConclusion: Our study confirms acceptable mid-term durability, clinical and hemodynamic performance of the Trifecta™ valve in middle age population, despite the fact of non- statically significant trend-up of transvalvular gradient over the follow up period. Further long-term studies with larger sample-size are warranted to confirm these results in our population.
