Patient-prosthesis mismatch following TAVR: time will tell

In this issue of EuroIntervention, the team from the University of Bern in Switzerland present their assessment of patient-prosthesis mismatch (PPM) following transcatheter aortic valve replacement (TAVR) at their centre through a prospectively maintained registry of 2,463 patients1. Tomii and colleagues explored three distinct assessments of PPM in the study population: measured PPM on the discharge echocardiogram, predicted PPM by the effective orifice area of the implanted TAVR prosthesis, and predicted PPM by preprocedural cross-sectional imaging. As our understanding of PPM continues to grow, this report offers real-world insight into the prevalence and implications of PPM.
