title: Transapical Cannulation Through a Transcatheter Aortic Valve Implantation Valve: A Novel Approach for Cardiogenic Collapse.
abstract: We report a case of rescue bypass cannulation of the ventricular apex during a transapical transcatheter aortic valve implantation procedure in a patient with peripheral vascular disease not amenable to peripheral cannulation. Following rapid pacing and deployment of the transcatheter valve, cardiac function did not recover. The arterial cannula was inserted through the left ventricular apex, at the site of the transapical sheath, and advanced across the prosthetic valve, allowing for rapid initiation of cardiopulmonary bypass. The patient׳s ventricular function recovered promptly and cardiopulmonary bypass was weaned without difficulty.
