Objective The impact of transcatheter aortic valve implantation (TAVI) on left ventricular (LV) mass regression is not well defined. We aimed to measure LV mass regression, changes in LV volumes and dimensions, as well as mitral valve function after TAVI. Methods Eighty patients who underwent TAVI between 2008 and 2010 were studied. Echocardiographic findings before procedure and at 6- and 12-month follow-up were analyzed. Results Aortic valve area increased from 0.71 (0.27) cm2 before procedure to 1.89 (0.64) cm2 at 12 months ( P < 0.001), which was associated with reduction in peak [80.79 (23) vs 16.9 (6.5) mm Hg, P < 0.001] and mean [47.65 (14.2) vs 8.77 (3.29) mm Hg, P < 0.001] gradients. At 1 year, there was a change in LV end-systolic volume [46.12 (36.6) to 48.96 (4.05) mL, P = 0.042] and LV mass [202.4 (92.2) to 183.6 (98.2) g, P = 0.04]. Left ventricular mass index regressed from 130.7 (28.9) to 122.1 (28.9) g/m2 ( P = 0.01). Maximum wall thickness decreased from 1.28 (0.18) to 1.25 (0.17) cm ( P < 0.001). There was no significant change in LV ejection fraction, LV end-systolic and end-diastolic diameters, as well as mitral valve regurgitation. Conclusions Transcatheter aortic valve implantation is associated with significant regression of LV hypertrophy at 1 year. However, this regression was not associated with changes in LV systolic and diastolic functions, size, or changes in mitral valve regurgitation.
