Multivessel Minimally Invasive Coronary Bypass Grafting as HYBRID Revascularization Versus Conventional Off-pump Coronary Artery Bypass Grafting

Sponsor: Catharina Ziekenhuis Eindhoven

View on ClinicalTrials.gov

Summary

The MICRA-HYBRID trial is a prospective, multicenter, randomized controlled study comparing multivessel hybrid coronary revascularization (HCR) as minimally invasive arterial bypass grafting to left-sided coronary targets (LAD and LCx) plus PCI of the RCA versus conventional off-pump coronary artery bypass grafting (OPCAB) via median sternotomy in patients with three-vessel coronary artery disease. The primary goal is to evaluate whether multivessel-HCR provides superior 30-day "textbook" clinical outcomes (mortality, MI, stroke, re-exploration for bleeding, and other complications) while improving perioperative recovery and long-term cardiovascular outcomes.

PROCEDURE

Multivessel Hybrid Coronary Revascularization

Multivessel-HCR consists of MICS revascularization of the left sided coronary vessels (LAD , Cx) combined with PCI for the RCA during the same admission or within 4 weeks postoperatively. Surgical revascularization is performed through MICS which consists of either robotically or non-robotically assisted thoracoscopic IMA harvesting followed by total arterial off-pump anastomosis of the grafts through a left anterior 3-5 cm mini-thoracotomy. PCI will be performed via radial or femoral access according to local routine and is restricted to the RCA.

PROCEDURE

Off-pump coronary arterial bypass grafting (OPCAB)

OPCAB will be performed as per clinical routine at each center through a median sternotomy. IMA harvesting (pedicled or skeletonised) follows each center's routine. An anaortic, total arterial strategy with a LIMA-LAD graft and complete revascularisation is obliged.
