N2 - Background We conducted a metaanalysis comparing early and midterm cardiovascular adverse events associated with minimally invasive direct coronary artery bypass graft surgery (MIDCABG) and percutaneous coronary intervention (PCI), with a focus on drug-eluting stents (DES). Methods A systematic literature review (MEDLINE, EMBASE, Scopus, and so forth) yielded 12 studies (7 randomized controlled trials; 5 observational) pooling more than 2,000 patients. A random effect, inverse variance metaanalysis was conducted, and a subgroup analysis of the PCI-DES cohort was performed. Events were compared as risk ratios using a 95% confidence interval (CI). Heterogeneity of results was evaluated by Eggers I2 test. Results are presented as early (0 to 1 year) and midterm (2 to 5 years). Results Midterm mortality in the PCI and MIDCABG groups (3.6% and 2.6%, respectively) was comparable (1.24, 95% CI: 0.66 to 2.33; p = 0.5; I2 = 0%). Risk of early restenosis was lower in the MIDCABG cohort compared with PCI (0.40, 95% CI: 0.16 to 0.99; p = 0.05; I 2 = 57%). Although the early risk of recurrence of angina was comparable, over time it was 61% (43% to 74%) lower for MIDCABG patients (p < 0.001). Midterm results on analysis of the entire cohort demonstrated an increased risk for target vessel reinterventions (3.84, 95% CI: 2.7 to 5.5; p < 0.001) in the PCI cohort. Subgroup analysis revealed that the PCI-DES cohort (4 studies; 456 patients) had a higher risk of recurrent angina (risk ratio 3.4, 95% CI: 1.9 to 6.2; p < 0.001; I2 = 0%) and target vessel reinterventions (risk ratio 4.16, 95% CI: 2.7 to 6.6; p < 0.001; I2 = 0%) at midterm follow-up (2 to 5 years). Conclusions Survival rates are comparable after either MIDCABG or PCI for proximal LAD disease. However, even the use of DES was associated with significantly higher rates of angina recurrence and the need for target vessel reintervention as compared with MIDCABG.
