OBJECTIVES: Evaluation of 3-year clinical outcome of hybrid myocardial revascularization (HMR) compared to conventional revascularization strategies in patients with multivessel coronary artery disease involving the proximal left anterior descending artery. Design. Retrospective matched cohort study based on a prospective feasibility study including 103 elective patients undergoing staged HMR from October 2010 until February 2012. The Western Denmark Heart Registry was used to identify patients who underwent coronary artery bypass grafting (CABG) and multivessel percutaneous coronary intervention (PCI) by matching on number of diseased vessels, age and comorbidity score. Primary endpoint was the composite rate of major adverse cardiovascular and cerebrovascular events (MACCE) at 3-year follow-up. Secondary endpoints included individual MACCE components, acute kidney injury, and cardiovascular readmissions. Results. There was no difference between MACCE in the three groups (HMR 31.1%; CABG 20.4%; PCI 20.4%, p = .11). Estimates of repeat revascularization were significantly increased with HMR versus CABG. In the CABG group, fewest patients required cardiovascular readmissions though with the highest incidence of acute kidney injury. Conclusions. HMR was not superior with respect to MACCE compared with CABG and PCI. It may, however, represent a safe alternative to conventional revascularization treatment considering the specific procedure-associated morbidity.
