Background:
Sutureless valves have recently enabled closed chest aortic valve replacement. This paper evaluates the feasibility of a robotic telemanipulation during thoracoscopic sutureless aortic valve implantation in cadavers.
Methods:
Cadavers were prepared with a five thoracosopic trocar setting, with a transthoracic clamp inserted in the first right intercostal space and the optics inserted in the second. Seven sutureless valve implantations were scheduled using 5 Sorin Perceval and 2 Medtronic 3f Enable valves.
Results:
In all cases performance of pericardial suspension, aortotomy and root exposure required less than 20 min. Native valve excision and sutureless bioprosthesis implantation was technically feasible in all cases. A satisfactory prosthesis sealing was ascertained visually and the absence of paravalvular leakages was assessed with a nerve hook test around the prosthetic flange.
Conclusions:
Closed chest and robot assisted sutureless valve implantation is feasible in cadavers. Robotic technology can enhance reproducibility of the technique. Copyright © 2015 John Wiley & Sons, Ltd.
