title: Catheter Insertion via Extracorporeal Membrane Oxygenation Cannula during Transcatheter Aortic Valve Implantation.
abstract: BackgroundPatients referred to transcatheter aortic valve implantation (TAVI) present with multiple risk factors for intraprocedural complications.Case DescriptionWe 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.ConclusionThis case report provides an option to insert a pigtail catheter after implantation of extracorporeal membrane oxygenator cannulas without need for additional vascular access.
