Background:
Venoarterial extracorporeal membrane oxygenation (VA-ECMO) offers hemodynamic support for patients undergoing high-risk percutaneous coronary interventions (PCIs). However, long-term outcomes associated with VA-ECMO have not previously been studied.
Aim:
To explore long-term outcomes in high-risk cases undergoing PCI supported by VA-ECMO.
Methods:
In the present observational cohort study, 61 patients who received VA-ECMO-supported high-risk PCI between April 2012 and January 2020 at the Sixth Medical Center of Chinese People's Liberation Army General Hospital were enrolled. The endpoint characteristics such as all-cause mortality, repeated cardiovascular diseases, and cardiac death were examined.
Results:
Among 61 patients, three failed stent implantation due to chronic total occlusions with severely calcified lesions. One patient showed VA-ECMO intolerance because of high left ventricular afterload. PCI was successfully performed in 57 patients (93.4%). The in-hospital mortality was 23.0%, and the overall survival was 45.9%, with a median follow-up period of 38.6 (8.6-62.1) mo.
Conclusion:
VA-ECMO can be used as a support in patients undergoing high-risk PCI as it is associated with favorable long-term patient survival.
