Prosthesis–Patient Mismatch in Patients Undergoing Transcatheter Aortic Valve Replacement
The authors, using the STS/ACC TVT Registry, analyzed the the occurrence of patient-prosthesis mismatch (PPM) in 62,215 patients enrolled between 2014 and 2017. They found that severe and moderate PPM occurred in 12% and 25% of patients, respectively. A greater degree of PPM was associated with a higher risk of mortality and rehospitalization at 1 year.
