RESUMO
OBJECTIVES: Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is most commonly used in patients with cardiac arrest and cardiogenic shock. There are limited data on the use of VA-ECMO for elective, high-risk percutaneous coronary intervention (PCI). We examined the in-hospital and mid-term clinical outcomes in patients undergoing complex, high-risk PCI with VA-ECMO support. METHODS: . We conducted a retrospective review of ECMO-supported elective high-risk PCIs performed at our institution between May 2012 and May 2017. The electronic medical records and angiograms were individually reviewed. We assessed the in-hospital and mid-term major adverse cardiovascular and cerebrovascular event (MACCE) rates, and reviewed bleeding and vascular complications. RESULTS: Five patients underwent elective high-risk PCI with ECMO support. Mean age was 66.8 ± 8.6 years and all patients were men. The mean ejection fraction was 26.6 ± 18.0%. Most procedures were unprotected left main PCIs. All PCIs were successful; 1 patient required femoral artery surgical repair. The mean hospital stay post procedure was 6.4 ± 2.0 days. ECMO was successfully weaned in all cases, and the duration of ECMO was <24 hours in 4 cases. There was no occurrence of in-hospital and 1-year MACCE. CONCLUSION: ECMO can be successfully used for hemodynamic support during elective high-risk PCI.
