Current landscape of hybrid revascularization: A report from the NCDR CathPCI Registry.
BACKGROUND: Hybrid revascularization, combining percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG), may be used differently across hospitals. How outcomes compare with multivessel PCI is unknown. METHODS: We studied hybrid revascularization use in patients in the National Cardiovascular Data Registry from 2009 to 2017 who underwent PCI for multivessel coronary artery disease (CAD) at 711 hospitals, excluding patients with prior CABG, acute ST-elevation myocardial infarction, emergency/salvage CABG, or PCI without stent placement. In-hospital mortality associated with hybrid revascularization versus multivessel PCI was compared using a multivariable logistic model. RESULTS: Among 775,000 patients with multivessel CAD, 1,126 (0.2%) underwent hybrid revascularization and 256,865 (33%) were treated with multivessel PCI. Although 358 (50.4%) hospitals performed hybrid revascularizations, most (97.3%) performed <1 per year. Most patients (68.7%) treated with hybrid revascularization underwent CABG after PCI; only 79.4% of these patients were discharged on P2Y12 inhibitors. Patients who underwent hybrid revascularization were younger and more likely to have significant left main or proximal left anterior descending disease. Unadjusted in-hospital mortality rates were higher among patients treated with hybrid revascularization than multivessel PCI (1.5% vs 0.9%, P = .02), a difference that was not significant after multivariable adjustment (odds ratio = 1.54, 95% CI = 0.92-2.59). CONCLUSIONS: Hybrid revascularization remains an infrequently used treatment modality for multivessel CAD. Risk-adjusted in-hospital mortality was no different between hybrid revascularization and multivessel PCI; however, patients who underwent hybrid revascularization were less likely to be discharged on P2Y12 inhibitor therapy despite stent implantation.
