Introduction
Sutureless/rapid deployment valves provide the surgeon with a new tool for aortic valve
replacement (AVR) therapy, which can simplify the procedure. The main concern about
sutureless/rapid deployment valves is the development of paravalvular leak. The incidence varies between 1-7%, and is associated with detrimental sequelae for the patient (1,2,3). In this series we would like to share our experience with using intraoperative Transesophageal Echocardiography to reliably predict the size of the rapid deployment prosthetic valve by measuring the native aortic annulus. This will hopefully provide the surgeon with extra assurance on valve sizing during rapid deployment Aortic valve replacement and minimize the possibility of paravalvular leak.
