Observational StudyType and Size of Implanted Bioprosthetic Valve Rather Than Intraoperative Peak Transprosthetic Valvular Velocity Predict Postoperative Midterm Prosthesis-Patient Mismatch in Patients Undergoing Surgical Aortic Valve Replacement.
High transprosthetic valvular peak velocity (PV) is indicative of prosthesis-patient mismatch (PPM), which exacerbates mortality and morbidity after surgical aortic valve replacement (AVR). During surgical AVR, a high intraoperative PV sometimes is detected, but whether it affects mortality and morbidity is unknown. The aims of this study were to determine whether intraoperative and postoperative PV were correlated and what factors predicted postoperative PPM. ⋯ There was no significant association between intraoperative and postoperative PV values. Implanted valve type and size, but not intraoperative PV, predicted postoperative PPM.
