| Popis: | Objective Distortion of transcatheter heart valve (THV) stent shape and morphology has been shown to impact on THV function. This study sought to evaluate the relationship between geometrical CT follow-up data and consequent valve function in patients undergoing transcatheter pulmonary valve replacement with the Edwards SAPIEN THV. Methods All patients were enrolled in the COMPASSION trial. Multidetector computed tomography (MDCT) was performed as part of the study protocol at 6 months and yearly thereafter following valve implantation. Prosthesis eccentricity indices, circularity ratios, and expansion ratios (ER) were calculated. Valve function and reintervention rates were correlated with MDCT findings. Results Twenty consecutive patients undergoing 58 CT scans were included. Maximum Doppler gradients across the right ventricular outflow tract (RVOT) were significantly reduced following valve implantation (P |
