Evaluation of Tp-e interval, Tp-e/QT and Tp-e/QTc ratio in aortic valve stenosis before and after transcatheter aortic valve implantation

Aortic stenosis (AS) is the most common form of degenerative valvular heart disease with a growing prevalence due to the ageing population [1]. In the presence of AS, increased left ventricular (LV) afterload leads to compensatory myocardial hypertrophy and results in elevated systolic wall stress and impaired coronary blood flow. Consequently, LV electrical heterogeneity occurs because of myocardial degeneration and fibrosis [2 –4]. Therefore, prevalence of ventricular arrhythmia as a reason of syncope and sudden cardiac death increases [5,6].
