Abstract
<p>OBJECTIVE:</p> <p>Comparing the hemodynamic profiles of the Trifecta™ aortic bioprosthesis with glide technology (Trifecta GT™) sizes 19 and 21 with the Perceval™ aortic bio prosthesis (Perceval™) sizes S and M in their hemodynamic performance in patients who underwent surgical aortic valve replacement.</p> <p> </p> <p>METHODS:</p> <p>Data of patients that underwent aortic valve substitution using Perceval™ #S, Perceval™ #M, Trifecta GT™ #19 and Trifecta GT™ #21 between July 2016 and July 2018 in our surgical department where retrospectively compared in regard to their hemodynamic performance variables: peak transvalvular gradient and indexed aortic valve area. We excluded many patients using only echocardiographic data from our institution to guarantee for more precision of the hemodynamic data, and choose a 1 Perceval™ to 2 Trifecta GT™ analysis approach. The independent variables T test was used to search for statistical significance.</p> <p>RESULTS:</p> <p>Data of 54 patients were analyzed: 18 Perceval™ (13 size M and 5 size S) and 36 Trifecta GT™ (7 size 19 and 19 size 21). The hemodynamic data and post-operative clinical status were evaluated by transthoracic echocardiography and follow up visit respectively, in the frame of 3 to 12 months post-surgery. The mean peak transvalvular gradient and the indexed aortic valve area were 33.80 mmHg and 0.92 cm2/m2 for Perceval™ #S, 25.71 mmHg and 1.00 cm2/m2for Perceval™ #M, 20.40 mmHg and 0.92 cm2/m2 for Trifecta GT™ #19 ,21.90 mmHg and 1.00 cm2/m2 for Trifecta GT™ #21. There was no statistically significant difference in body surface area and left ventricular ejection fraction between groups. The difference in the peak transvalvular gradient was statistically significant for comparison of Perceval™ #S and Trifecta GT™ #19 (p < 0.01). No statistic significant differences were found in the peak transvalvular gradients between Perceval™ #M and Trifecta GT™ #21. No statistically significant differences were found concerning the indexed aortic valve area.</p> <p> </p> <p>CONCLUSIONS:</p> <p>The hemodynamic performance of the Trifecta GT™ #19 seems superior to that of Perceval™ #S in this small population. The clinical relevance of this finding should be confirmed in a study with a bigger population, ideally randomized and prospective.</p> <p> </p>
