Meta-analysis of minimally invasive coronary artery bypass versus drug-eluting stents for isolated left anterior descending coronary artery disease


Journal Article

© 2014 by The American Association for Thoracic Surgery. Results From 230 publications, we identified 4 studies (2 randomized and 2 observational) with 941 patients (478 had undergone MINI-CAB and 463 DES implantation). The incidence of target vessel revascularization at maximum follow-up (range, 6-60 months) was significantly lower in the MINI-CAB group (OR, 0.16; 95% CI, 0.08-0.30; P <.0001; number needed to treat, 13). The incidence of cardiac mortality and MI was similar between the MINI-CAB and DES groups during follow-up (OR, 1.05; 95% CI, 0.44-2.47; and OR, 0.83; 95% CI, 0.43-1.58, respectively). In addition, a similar incidence of periprocedural death (OR, 0.85; 95% CI, 0.21-3.47; P =.82), myocardial infarction (OR, 0.98; 95% CI, 0.38-2.58; P =.97), and stroke (OR, 1.36; 95% CI, 0.28-6.70; P =.70) was observed between the 2 treatment modalities.Conclusions Given the available evidence, MINI-CAB will result in lower target vessel revascularization rates but otherwise similar clinical outcomes compared with DESs in patients with left anterior descending artery disease.Objective To compare the outcomes between minimally invasive coronary artery bypass (MINI-CAB) and drug-eluting stent (DES) implantation for isolated left anterior descending artery disease.Methods Randomized and observational comparative publications were identified using MEDLINE and Google Scholar databases (January 2003 to December 2013). Studies without outcomes data, without DES use, or using conventional bypass surgery were excluded. The outcomes of interest were cardiac death, myocardial infarction, target vessel revascularization, and periprocedural stroke. Data were compared using the Mantel-Haenszel methods and are presented as odds ratios (ORs), 95% confidence intervals (CIs), and number needed to treat.
