Abstract

Objective:We evaluated short-term outcomes and mid-term survival and reintervention of hybrid coronary revascularization versus conventional coronary artery bypass grafting using a propensity score matched cohort. Methods: We conducted a retrospective review of patients undergoing surgery for multivessel coronary artery disease from 2007 to 2015 at a single institution. Patients were propensity matched 1:1 to receiving hybrid coronary revascularization or conventional bypass grafting by multivariate logistic regression on preoperative characteristics. Shortterm outcomes were compared. Freedom from reintervention and death were assessed by Kaplan-Meier analysis, log-rank test, and Cox proportional hazards regression. Results: Propensity score matching selected 91 patients per group from 91 hybrid and 2601 conventionally revascularized patients. Hybrid revascularization occurred with surgery first in 56 (62%), percutaneous intervention first in 32 (35%), and simultaneously in 3 (3%) patients. Median intervals between interventions were 3 and 36 days for surgery first and percutaneous intervention first, respectively. Preoperative characteristics were similar. Patients undergoing hybrid revascularization had shorter postoperative length of stay (median = 4 vs 5 days, P < 0.001), less postoperative transfusion (13.2% vs 34.1%, P = 0.001), and respiratory failure (0% vs 6.6%, P = 0.03). They were more likely to be discharged home (93.4% vs 71.4%, P < 0.001), with no difference in 30-day mortality (P = 0.99), readmission (P = 0.23), or mid-term survival (P = 0.79). Hybrid revascularization was associated with earlier reintervention (P = 0.02). Hazard ratios for reintervention and patient mortality of hybrid coronary revascularization versus conventional revascularization were 3.60 (95% confidence interval = 1.16-11.20) and 1.17 (95% confidence interval = 0.37-3.72), respectively. Conclusions: Despite having favorable short-term outcomes and similar survival, hybrid coronary revascularization may be associated with earlier reintervention compared with conventional techniques.
