英文摘要: Abstract(#br)Objective(#br)This study aimed to assess the predictors of patient–prosthesis mismatch (PPM) after surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR) using preoperative computed tomography.(#br)Methods(#br)We enrolled 323 patients undergoing SAVR (n = 85) or TAVR (n = 238) for aortic stenosis. The end point was any degree of PPM (effective orifice area index <0.85 cm 2 /m 2 ). We assessed the predictors of PPM after SAVR or TAVR and compared the incidence of PPM between both arms. Furthermore, we compared the hemodynamic performance using the propensity score matching.(#br)Results(#br)The occurrence of PPM was significantly higher in the SAVR arm (24.7% vs 7.1%; P < .001). A small sinotubular junction was an independent predictor of PPM...
