Abstract
ABSTRACT: BACKGROUND: Use of new generation small prostheses for aortic valve replacement has decreased the need for annular enlargement and rarely increased the incidence of severe patient-prosthesis mismatch; OBJECTIVE: Of this study is to evaluate the impact of using this type of prosthesis (St.Jude. HP, Regent) on operative mortality. PATINETS & METHODS: We reviewed our experience (59) consecutive patients who had isolated and combined aortic valve replacement in our hospital between February 2001 and February 2007. RESULTS: The mean age was 36, and 60 % of patients were female.valvular disease was primarily pure aortic regurgitation 47%, combined aortic disease 29% and pure aortic stenosis was present in 24%. CONCLUSION: Evaluation of the impact of newly designed small prosthesis on thirty-day mortality revealed: thirty-day mortality was 8% and the strongest independent predictors in multivariate analysis in decreasing order of statistical power were functional class IV, patient-prosthesis mismatch, advanced age (65 year), very small valve size (labeled valve size 17-mm), isolated aortic valve replacement surgery without other concomitant procedure (P=0.022) and obese patients (body mass index >33 kg/ m²).
