Percutaneous aortic valve replacement: Transapical resection of the aortic valve in vivo

Resection of Calcified Aortic Heart Leaflets In Vitro by Q-Switched 2 µm Microsecond Laser Radiation

“…This was proposed and already demonstrated in animal trials. 9 Using a water-flushed resection chamber which isolates the heart valve against the blood circulation allows filtering of debris, thus preventing the particles from entering the vascular system. In order to resect the valves in this confined volume, a continuous wave (cw) 2 mm laser system was investigated.…”
