Objective: It has been demonstrated that performing percutaneous coronary intervention (PCI) in the
absence of mechanical circulation support (MCS) for patients with complex high-risk coronary artery
disease bears a high risk. Alternatively, to figure out the procedure effectiveness and the mid-term prognosis
of PCI for complex high-risk coronary artery disease, we accomplished the whole process by the assistance
of extracorporeal membrane oxygenation (ECMO).
Methods: Between July 2016 and October 2017, 6 consecutive complex and high-risk coronary disease
patients underwent routine ECMO-supported PCI.
Results: The average age of the patients was 70.5±11.98, and half of them (50%) were male. The mean
creatinine (Cr) was 188.67±151.68 µmol/L. The average scores for SYNTAX, SYNTAX II, and LVEF pre
the procedure was 41.33±12.14, 47.87±9.45 / 31.55±8.82, and 44.40±12.58%, respectively. The mean
supporting duration of ECMO was 10.50±7.79 h. Regarding the postoperative complication, one case
observed lower limp venous thrombosis and another reported infection at the access site. Two patients
(33.3%) died for refractory heart failure during the follow-up course of 17.00±9.51 months, and the average
net improvement index (NII) was 28.30±25.11% for this period.
Conclusion: With the support of ECMO, the prognosis of complex high-risk coronary disease has
shown to be improved by intervention in our study.
