Cardiologists may want to rethink how they track prosthesis-patient mismatch after TAVR

The Bern TAVI Registry looked at 2,500 TAVR patients to determine the level of prosthesis-patient mismatch (PPM) using transthoracic echocardiography (TTE), predicting PPM based one the size of the valve used, or using CT measurements of the aortic annulus to see which was method was most accurate at predicting PPM.

Researchers evaluated two techniques for predicting PPM after TAVR, comparing them to how cardiologists typically check for PPM in day-to-day practice.
