Background There are limited data on the use of venoarterial extracorporeal membrane oxygenation (VA‐ECMO) or cardiopulmonary bypass (CPB) to provide hemodynamic support periprocedurally during transcatheter aortic valve replacement. This study sought to evaluate patients receiving transcatheter aortic valve replacement with concomitant use of CPB/VA‐ECMO. Methods and Results We systematically reviewed the published literature from 2000 to 2018 for studies evaluating adult patients requiring CPB/VA‐ECMO periprocedurally during transcatheter aortic valve replacement. Studies reporting short‐term and long‐term mortality were included. Given the significant methodological and statistical differences between published studies, meta‐analysis of the association of CPB/VA‐ECMO with mortality was not performed. Of the 537 studies identified, 9 studies representing 5191 patients met our inclusion criteria. Median ages were between 75 and 87 years with 33% to 75% male patients. Where reported, the Edwards SAPIEN™ transcatheter heart valve was the most frequently used. A total of 203 (3.9%) patients received periprocedural hemodynamic support with CPB/VA‐ECMO. Common indications for CPB/VA‐ECMO included left ventricular or aortic annular rupture, rapid hemodynamic deterioration, aortic regurgitation, cardiac arrest, and left main coronary artery obstruction. The use of CPB/VA‐ECMO was predominantly an emergent strategy and was used for durations of 1 to 2 hours. Short‐term mortality (in‐hospital and 30‐day) was 29.8%, and 1‐year mortality was 52.4%. Major complications such as bleeding, vascular injury, tamponade, stroke, and renal failure were noted in 10% to 50% of patients. Conclusions CPB/VA‐ECMO was used in 4% in the early experience of patients undergoing transcatheter aortic valve replacement, most commonly for periprocedural complications. There are limited data on preprocedural planned use of VA‐ECMO, and the characteristics of this population remain poorly defined.
