- W4236873863 abstract "Some important studies have shown that patient-prosthesis mismatch is a frequent occurrence after surgical aortic valve replacement that impairs survival. The Trifecta valve (St. Jude Medical Inc, St. Paul, MN) has special architecture designed to achieve the best hemodynamic profile. The aim of this study was to determine the prevalence of mismatch when using this prosthesis.This study included 1,302 patients at 3 months postoperatively, 339 patients with a Trifecta prosthesis and 963 patients (the control group) with a Mitroflow aortic valve (Sorin Group Inc, Mitroflow Division, Vancouver, Canada). Multinomial multivariate logistic regression was calculated to estimate the association between the Trifecta prosthesis and moderate or severe patient-prosthesis mismatch.Any degree of mismatch was present in 5.9% of the Trifecta group and in 42.4% in the Mitroflow group. Moderate patient-prosthesis mismatch was present in 3.8% of the patients with a Trifecta valve and in 32.6% in the Mitroflow group. Severe mismatch was present in 2.1% of the patients with a Trifecta prosthesis and in 9.8% of the patients with a Mitroflow valve. All differences were statistically significant (p < 0.001). The odds ratio of the Trifecta prosthesis as protector against mismatch was 16.9 (95% confidence interval, 9.5 to 30.4) and 11.9 (95% confidence interval, 5.3 to 26.7) for moderate or severe mismatch, respectively.The prevalence of patient-prosthesis mismatch using the Trifecta aortic prosthesis is extraordinary low. This finding may have great clinical repercussions in patients undergoing surgical aortic valve replacement." @default.
