[Transcutaneous coronary intervention with the use of extracorporeal membrane oxygenation in patients with acute coronary syndrome].

Analysed herein are the in-hospital and remote (12 months) results of transcutaneous coronary interventions (TCI) carried out in patients with non-ST elevation acute coronary syndrome (nSTE-ACS) and multivessel coronary artery disease with the use of extracorporeal membrane oxygenation (ECMO). From 2013 to 2015, the study included a total of 18 patients with nSTE-ACS and multivessel coronary artery disease who had been denied "open" surgical myocardial revascularization. The mean values (scores) of the scales in the group were as follows: GRACE - 119.7±67.6, SYNTAX Score - 33.5±8.1, Euroscore II - 5.2±21.9. The ejection fraction was averagely moderately low - 49.3±19.4%. During the in-hospital stay of the patients and 12 months after TCI we assessed the major adverse cardiovascular events (MACE): death, myocardial infarction, acute cerebral circulation impairment/transitory ischaemic attack, repeat revascularization of the target vessel - both as separate parameters and in a composite form. Additionally, we analysed perioperative and in-hospital complications, their structure, the volume of replacement therapy with blood components and the length of hospital stay. During the in-hospital period and at 12 months of follow up, the composite number of cases of adverse cardiovascular events amounted to 1 (5.5%) and 3 (16.5%), respectively. One patient died during in-hospital treatment and one more lethal outcome was registered by 12 months of follow up; hence, the mortality rate amounted to 1 (5.5%) and 2 (11%) cases, respectively. Stroke was observed in 1 (5.5%) patient only during the in-hospital period. No repeat revascularisation of the target vessel was performed. By the end of the hospital stay, BARC type 3-5 haemorrhagic complications were observed in 50% of patients. The in-hospital and remote (12 months) results of high-risk TCI with ECMO support in patients with nSTE-ACS and multivessel coronary artery disease, who had been denied surgical revascularization demonstrated an acceptable level of unfavourable outcomes. This approach may be regarded as a method alternative to revascularization and used in an utterly severe cohort of patients.
