Catheter Insertion via Extracorporeal Membrane Oxygenation Cannula during Transcatheter Aortic Valve Implantation.

Background  Patients referred to transcatheter aortic valve implantation (TAVI) present with multiple risk factors for intraprocedural complications. Case Description  We describe a TAVI procedure with sudden hemodynamic collapse and cardiopulmonary resuscitation. Therefore, extracorporeal membrane oxygenation cannulas were immediately implanted via vessels of the groin. A Y-connector was inserted into the arterial line of the extracorporeal membrane oxygenator using an additional sheath facilitating to insert a pigtail catheter to guide the further valve implantation. Conclusion  This case report provides an option to insert a pigtail catheter after implantation of extracorporeal membrane oxygenator cannulas without need for additional vascular access.
