| Values are mean±standard deviation or n (%). BMI: body mass index; EOAi: effective orifice area indexed to body surface area; EOAiCT: predicted EOA based on the normal reference values of EOA derived from aortic annulus dimensions measured by preprocedural computed tomography; EOATHV: predicted EOA based on the normal reference values of EOA for each size and type of implanted transcatheter heart valve; PPM: prosthesis-patient mismatch; PPMCT: PPM defined by predicted EOA derived from preprocedural computed tomography; PPMTHV: PPM defined by predicted EOA for each size and model of implanted transcatheter heart valve | ||||
