Prospective multicenter registry of hybrid coronary artery revascularization combined with non-saphenous vein graft surgical bypass and percutaneous coronary intervention using everolimus eluting metallic stents (PRIDE-METAL study).

The concept of hybrid coronary revascularization (HCR) combines the advantages of coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) to improve the treatment of patients with complex multivessel disease. This study aimed to investigate a 1-year clinical follow-up of a prospective multicenter registry of HCR combined with non-saphenous vein graft surgical bypass and PCI using everolimus-eluting metallic stents (the PRIDE-METAL study). From June 2016 to June 2018, a total of 54 patients with multivessel coronary disease from six Japanese institutes were enrolled in this study. The primary endpoint of the study was the occurrence of major adverse cardiovascular event (MACE; all-cause death, myocardial infarction, stroke, and repeat revascularization) at 1 year. Three patients declined before complete HCR, and two patients were lost by the 1-year follow-up. All-cause mortality at 30 days and at 1 year was 0% and 4.1%, respectively. The rates of myocardial infarction, repeat revascularization, stroke, and MACE were 0% at 30 days, and 0%, 2.0%, 2.0%, and 8.2% at 1-year follow-up, respectively. No occlusion of arterial bypass graft at the 30-day follow-up was observed, and was observed in 1.7% at the 1-year follow-up. HCR was safe and feasible and associated with a low risk of MACE at the 1-year follow-up. Further validation in multicenter and randomized studies is needed.
