1 (1.2%) and 3 (3.5%) PMP patients, respectively. After TAVR procedure the degree of mitral regurgitation decreased by at least 1-degree in all patients with moderate-severe insufficiency and half-pressure time decreased by 89.76±6.6 msec (p=0.015), with no changes in mean gradients (p=0.20). Valve embolization occurred in 6 patients (6.7%), all of them with a distance shorter than 7 mm between the PMP and the aortic annulus as assessed by MDCT (p<0.001). Risk of embolization was neither

Distance between PMP and Aortic annulus Conclusions: MDCT helped to determine that TAVR could be performed in patients with PMP presenting a distance from PMP to aortic annulus larger than 7-mm with extremely low risk of valve embolization. In patients with shorter distance, the use of transapical vs. transfemoral approach or self-vs. balloonexpandable devices did not reduce this risk. After TAVR, mean transmitral gradients were comparable but a significant decrease in half-pressure time and rate of moderate-severe mitral regurgitation were found.
