    LITERATURE WAS REVIEWED REGARDING THE DIFFERENCES IN BLOOD FLOW DYNAMICS BETWEEN SELF-EXPANDING (SEV) AND BALLOON-EXPANDABLE VALVES AFTER TRANSCATHETER AORTIC VALVE REPLACEMENT (TAVR). THE STUDY POPULATION CONSISTED OF 166 PATIENTS WHO UNDERWENT TAVR WITH EITHERA MEDTRONIC SEV PRODUCT (EVOLUT R/PRO/PRO+/FX, N = 56) OR A NON-MEDTRONIC BEV PRODUCT (SAPIEN, N = 110). AMONG ALL 166 PATIENTS, THE AUTHORS OBSERVED VARYING DEGREES OF ELEVATED MEAN PRESSURE GRADIENTS (9 TO 14 MM HG) AND PARAVALVULAR LEAK (MILD TO SEVERE) AFTER TAVR. NO INTERVENTIONS WERE RECOUNTED IN THE ARTICLE.
