Abstract

<p>Background:The changes in electrocardiographic left ventricular hypertrophy (ECG-LVH) after transcatheter aortic valve implantation (TAVI) are not fully elucidated.</p><p>Methods and Results:The study group included 64 patients who underwent TAVI for aortic stenosis. Their 12-lead ECGs before and at 2 days and 1, 6 and 12 months after TAVI were analyzed, and ECG-LVH was evaluated using various definitions. Values and prevalence of each ECG-LVH parameter significantly decreased between 1 and 6 months after TAVI. Values of ECG-LVH parameters decreased especially in patients with ECG-LVH at baseline.</p><p>Conclusions:Regression of ECG-LVH was observed between 1 and 6 months after TAVI.</p>
