Hybrid Coronary Revascularization Versus Conventional Coronary Artery Bypass Surgery: Utilization and Comparative...

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology
• Health Outcomes Research

Background:

• Hybrid coronary revascularization (HCR) combines minimally invasive surgery and percutaneous coronary intervention for multivessel coronary artery disease.
• Conventional coronary artery bypass grafting (CABG) is a standard treatment for multivessel coronary artery disease.

Purpose of the Study:

• To compare the medium-term outcomes of HCR versus conventional CABG in patients with multivessel coronary artery disease.
• To evaluate differences in mortality and repeat revascularization rates between HCR and CABG.

Main Methods:

• Utilized data from New York's cardiac surgery and percutaneous coronary intervention registries (2010-2016).
• Compared mortality and repeat revascularization rates using propensity matching to mitigate selection bias.
• Analyzed outcomes for 303 HCR patients and 37,556 conventional CABG patients.

Main Results:

• No significant difference in 6-year survival between HCR and conventional CABG (80.9% vs. 85.8%).
• HCR demonstrated higher mortality after the first year (adjusted hazard ratio, 1.88).
• Conventional CABG patients had significantly lower rates of repeat revascularization at 6 years (88.2% vs. 76.6%).

Conclusions:

• HCR is infrequently utilized for multivessel coronary artery disease.
• While 6-year mortality is similar, HCR is associated with increased late mortality and higher rates of subsequent revascularization.
• Findings suggest careful consideration of HCR's risks and benefits in patient selection for multivessel coronary artery disease.
