Objective"Patient-prosthesis mismatch" (PPM) after aortic valve replacement (AVR) has been reported to increase morbidity and mortality. Although algorithms have been developed to avoid PPM, factors favouring its occurrence have not been well defined.Design and settingThis was a prospective cohort study performed at the Medical University of Vienna.Patients361 consecutive patients who underwent aortic valve replacement for isolated severe aortic stenosis were enrolled.Main outcome measuresPatient- as well as prosthesis-related factors determining the occurrence of moderate and severe PPM (defined as effective orifice area indexed to body surface area ≤ 0.8 cm(2)/m(2)) were studied.ResultsPostoperatively, 172 patients (48%) were diagnosed with PPM. The fact that predominantly female patients were affected (58% with PPM diagnosis in women versus 36% in men, pConclusionsThe occurrence of PPM is determined by aortic root diameter and prosthesis type. Novel sutureless bioprostheses with optimized hemodynamic performance or transcatheter aortic valves may become a promising alternative to conventional bioprosthetic valves in the future. |
