Abstract

New surgical techniques for heart valve repair and new transcatheter valves can be effectively supported by in vitro tests [Jimenez, 2005]. Moreover, in order to maintain the structural continuity of the natural heart tissues and properly replicate the physiological and/or surgical scenarios, the integration of biological samples into in vitro mock loops is fundamental [Notzold, 2005]. A mock loop able to house an entire explanted porcine heart and subject it to pulsatile fluiddynamic conditions was developed. The system allows the performance of surgical procedures for heart valve repair, the implant of transcatheter heart valves and the acquisition of both echographic and endoscopic images of the cardiac structures.
