ObjectiveTo compare the outcomes between minimally invasive coronary artery bypass (MINI-CAB) and drug-eluting stent (DES) implantation for isolated left anterior descending artery disease.MethodsRandomized 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.ResultsFrom 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.ConclusionsGiven 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.Copyright © 2014 The American Association for Thoracic Surgery.
