Proof of Concept of an Endoscopic Sutureless Valve Sizer

Abstract: Objective In this paper, we present an endoscopic expandable sizer conceived to allow thoracoscopic aortic valve replacement with a sutureless prosthesis using a dynamic sizing of the aortic annulus. Methods Ten aortic torsos were prepared using a five-trocar thoracoscopic setting. Once the aortotomy was performed and the aortic valve leaflets removed, the technical feasibility of the endoscopic sizing (in… Show more

“…An expandable or collapsible valve sizer would be much more advantageous. 11 In the era of transcatheter aortic valve implantation (TAVI), robotic AVR provides an alternative treatment strategy for patients who are seeking a minimally invasive approach to their aortic valve who are not suitable candidates for TAVI, such as patients who are young (<60 years old), with bicuspid valve, or with large annuli.…”

“…Sutureless and rapid deployment (SURD) aortic bioprostheses were developed in parallel with transcatheter heart valves (THV), to simplify surgical aortic valve replacement (AVR) in complex scenarios like minimally invasive AVR, AVR in the heavily calcified aortic annulus/ root, and AVR in the small aortic annulus. SURD valves share some advantageous features with both sutured aortic bioprostheses (removal of the native valve, decalcification of the annulus, controlled deployment under direct visual control) and transcatheter valves [no need to stitch the annulus, increased effective orifice area due to the absence of pledgets and the mechanical thrust exerted by the inflow stent on the left ventricular outflow tract (LVOT)], and have been shown to be useful and effective in several specific contexts (1).…”
