MiECC Versus Conventional Cardiopulmonary Bypass in Cardiac Surgery (MiECS)
Minimally Invasive Extracorporeal Circulation Versus Conventional Cardiopulmonary Bypass in Patients Undergoing Cardiac Surgery (MiECS): a Randomised Controlled Trial
Source: ClinicalTrials.gov · Last updated 30 Mar 2026
Brief summary (registry, in English)
MiECS is one of the largest multicentre randomised controlled trials on extracorporeal circulation conducted under the auspices of Minimal Invasive Extracorporeal Technologies International Society (MiECTiS). It is designed to ultimately address the emerging effectiveness of MiECC systems in the light of modern perfusion practice worldwide. The primary hypothesis is that MiECC, as compared to conventional CPB (cCPB), reduces the proportion of patients experiencing serious perfusion-related postoperative morbidity after cardiac surgery. The study will be led by the Clinical Research Unit of the Special Unit for Biomedical Research and Education (SUBRE), Aristotle University of Thessaloniki School of Medicine in Greece (AUSoM) with Chief Investigator Professor Kyriakos Anastasiadis, who is a key-opinion-leader in the field of MiECC, founder and Executive Board of MiECTiS.
