The Impact of Energy Loss Index and Body Mass Index on Prosthesis Patient Mismatch
Prosthesis-patient mismatch (PPM) occurs following transcatheter aortic valve replacement (TAVR) with conflicting data on prognosis. It is considered present when the echocardiographic-derived indexed aortic valve area (iAVA) is
This retrospective study included consecutive patients undergoing TAVR from October 2014 through December 2019. Based on the iAVA values, patients were placed into categories of no PPM (>0.85 cm2/m2), moderate PPM (0.65-0.85 cm2/m2), or severe PPM (
This study included 324 patients. The incidence of severe PPM decreased using iAVA vs. ELI with poor to moderate agreement: no PPM – 73% iAVA vs. 88% ELI (κ = 0.54), moderate PPM – 13% iAVA versus 6.5% ELI (κ < 0), severe PPM – 14% iAVA vs 5.5% ELI (κ = 0.52).
Our study concludes that using ELI-based vs iAVA-based definition of PPM decreases the reported incidence and severity of PPM post-TAVR.
