Application of Emergent Peripheral Mechanical Circulatory Support in Transcatheter Aortic Valve Replacement for 6 Patients

Objective: To explore the experience of transcranial aortic valve replacement (TAVR) under emergency mechanical assisted circulation (MCS).Methods: A total of 6 patients who completed TAVR with the assistance of emergency MCS in the Second Affiliated Hospital of Zhejiang University School of Medicine from March 2013 to June 2019 were retrospectively analyzed.The management of perioperative mechanical assisted circulation, preoperative evaluation, intraoperative operation and postoperative situation of patients were summarized.
