Abstract: Background: Mechanical circulatory support may facilitate high-risk percutaneous coronary intervention (PCI). This study aimed to assess the feasibility, safety and effectiveness of high-risk PCI under the support of venoarterial extracorporeal membrane oxygenation (VA-ECMO) combined with intra-aortic balloon pump (IABP). Methods: We enrolled patients who received VA-ECMO plus IABP-assisted PCI procedures at our center from April 2012 to June 2018. Major adverse cardiac events (MACEs) included all-cause death, myocardial infarction, and target vessel revascularization. Results: A total of 10 patients were included, with a mean age of 71 years, EuroSCORE II of 19.9%, and SYNTAX score of 39.8. Procedural success was achieved in nine (90%) patients. The mean duration of ECMO support was 1.5 hours, and 2.6 stents were implanted per patient. Major complications included contrast-induced nephropathy needing hemodialysis in one (10%) patient, significant hemoglobin drop requiring blood transfusion in two (20%) patients, pulmonary infection in one (10%) patient, and local surgical incision infection in one (10%) patient. The accumulative mortality rates for the nine patients with procedural success were 0, 22.2%, and 44.4% at 1, 3, and 5 years follow-up, respectively. However, cardiac death occurred in only one (11.1%) patient. In addition, two patients received repeat PCI or coronary artery bypass grafting within two years following the index procedure. The overall incidence rates of MACEs were 11.1%, 44.4%, and 66.7% at 1, 3, and 5 years follow-up, respectively. Conclusions: VA-ECMO plus IABP-assisted high-risk PCI was feasible in patients with complex coronary disease, with a high procedural success rate and acceptable mid-term clinical outcomes.
