Revascularization for Coronary Artery Disease and Mitral Regurgitation: A Systematic Review and Meta-analysis.

Mortality Rates Between Coronary Artery Bypass Grafting and Percutaneous Coronary Intervention Over Time In terms of in-hospital mortality rates, Lin et al reported a 10.5% mortality rate for CABG + MVR vs 14% for PCI (P = 0.362), although this did not reach statistical significance. 10 Wang et al reported a higher mortality rate for propensity-matched patients undergoing PCI + TMVr compared to CABG + SMVr (13.8% vs 4.5%, P = 0.034). 11 One study, Kang et al, reported on 30-day mortality rate, finding no difference between CABG and PCI (1.7% vs 3.0%, P = 0.62). 12 Pooled estimates of 30 day mortality identified no significant difference between interventional or surgical approaches to revascularization (OR: 1.80, 95% CI: 0.78–4.15, z -score 1.38, P = 0.17) (Fig. 2 A).
