OBJECTIVES: The purpose of this study was to determine which echocardiographic parameters, including holodiastolic flow reversal (HDFR) in the descending aorta, were useful for grading of post-procedural @entity337 (PAR) after transcatheter aortic valve replacement (TAVR) using intraprocedural transesophageal echocardiography. BACKGROUND: Reliable assessment of PAR in a catheterization laboratory is essential for an optimal outcome after TAVR; however, such an assessment has not been determined. METHODS: Three hundred eighty @entity1 who underwent TAVR with the Edwards (Irvine, California) balloon-expandable transcatheter heart valve were retrospectively assessed by intraprocedural transesophageal echocardiography. PAR was evaluated by 2-dimensional color Doppler and pulse-wave Doppler in the descending aorta. Using 2-dimensional color Doppler, we measured the cross-sectional area of the vena contracta, the circumferential extent at the aortic annular plane, the longitudinal jet length, and the jet extent (with a mosaic pattern in the left ventricular outflow tract) compared with the location of the tip of the @entity1347 ( @entity1347 ). Grading of PAR was determined using the following vena contracta cutoffs: mild   <=9 mm(2); moderate 10 to 29 mm(2); and severe  >= 30 mm(2). Significant PAR was defined as at least moderate grade. RESULTS: All @entity1 with consistent HDFR had significant PAR. By multivariable analysis, consistent HDFR and the jet extent beyond the tip of @entity1347 were independent predictors of significant PAR. Consistent HDFR and jet extent beyond the tip of @entity1347 predicted significant PAR with specificities of 100% and 97%, respectively. In contrast, @entity1 with both negative HDFR and a jet extent of less than halfway to the tip of @entity1347 had no significant PAR, with 97% specificity. CONCLUSIONS: The presence of consistent HDFR and jet extent beyond the tip of @entity1347 are indicative of significant PAR after TAVR.
