Left Internal Thoracic Artery Bypass Versus Percutaneous Revascularization in Diabetics

Inclusion Criteria: * Male or Female age 18 years or older * Diabetes Mellitus (Type 1 or Type 2) undergoing treatment * Angiographically confirmed stenosis (≥ 70%) lesion of the proximal LAD (segment 6) or mid LAD (segment 7), with no culprit lesion or stenosis of more than 60% (in a vessel of 1.5 mm or more) in the LCX and RCA territories, and no stenosis equal or more than 50% in the left main artery. Diagonal disease does not constitute an exclusion * Angiographic characteristics amenable to both PCI/DES and MICS CABG * Indication for revascularization based upon symptoms of angina and/or objective evidence of myocardial ischemia * Willing to comply with all follow-up required study visits * Signed and received copy of informed consent Exclusion Criteria: * Severe congestive heart failure (class III or IV according to NYHA, or pulmonary edema) at the time of enrollment. * Left ventricular ejection fraction less than 20%; * Prior CABG surgery. * Prior Valve surgery. * Prior PCI with stent implantation within 6 months. * Previous tuberculosis or trauma to the chest that may have cause adhesions or LITA damage. * Previous stroke within 6 months or patients with stroke at more than 6 months with significant residual neurologic involvement, as reflected in a Rankin Score \> 1. * Prior history of significant bleeding (within the previous 6 months) that might be expected to occur during CABG or PCI/DES related anticoagulation. * In-stent restenosis in the LAD. * Left main ste…
