INTRODUCTION Severe aortic stenosis is the most common valvular heart disease with a prevalence of 2.8% in adults older than 75 years. Aortic valve replacement (AVR) using a biological valve prosthesis is the conventional treatment option for severe aortic stenosis. Nevertheless, in recent years, other therapeutic strategies have been developed with the aim of reducing mortality and morbidity as well as the invasiveness of surgical procedure. Transcatheter aortic valve implantation (TAVI...
