چکیده

BACKGROUND The use of the bilateral internal mammary arteries has been reserved mainly for younger and low risk patients. AIM To assess the safety and efficacy of BIMA grafting in older patients (> or = 70 years). METHODS We reviewed the records of all consecutive patients > or = 70 years old who underwent coronary artery bypass surgery with a BIMA graft in our institute over a 2 year period. Demographic data, operative data, perioperative morbidity and mortality were recorded. Findings were compared with a matched-size group of patients who underwent CABG with a left internal mammary artery graft to left anterior descending artery. RESULTS The study sample included 136 patients, of whom 68 underwent BIMA grafting and 68 LIMA grafting. Baseline demographic and clinical characteristics were similar in the two groups. There was no significant difference in operative mortality between the BIMA and LIMA groups (1.5% vs. 0%, P = 0.3) or in mortality during follow-up at a mean of 16 months (4.4% vs. 2.9%, P = 0.4, respectively). There was no difference between the groups in the incidence of perioperative complications, readmission and reintervention rates during follow-up. Significant between-group differences were noted for mean cardiopulmonary bypass time (93.2 +/- 34.7 min with BIMA vs. 108.8 +/- 40.7 min with LIMA, P = 0.02) and for red blood cell transfusion (1.9 +/- 1.9 vs. 4.3 +/- 2.8 packed cells/patient, P < 0.001). CONCLUSIONS The performance of mainly arterial revascularization with BIMA grafting in patients 70 years or older is as safe as LIMA grafting, with the added advantage of being a better conduit than saphenous vein graft, requiring fewer blood transfusions, and shorter cardiopulmonary bypass time.

Skeletonized bilateral internal mammary artery grafting for patients with diabetes.

To minimize sternal ischemia, skeletonized internal mammary artery (IMA) harvesting has been performed in the last few years. The benefits of skeletonization in high risk patients, such as diabetic patients undergoing bilateral IMA grafting, are unknown. A total of 99 patients underwent isolated coronary artery bypass grafting (CABG) using a pedicled bilateral IMA between 6/1/1997 and 5/31/2000...

Protocol for the Arterial Revascularisation Trial (ART). A randomised trial to compare survival following bilateral versus single internal mammary grafting in coronary revascularisation [ISRCTN46552265]

BACKGROUND Standard coronary artery bypass graft surgery uses a single internal mammary artery and supplemental vein or radial artery grafts. Several observational studies have suggested a survival benefit with two internal mammary artery grafts compared to a single internal mammary artery graft, but this has not been tested in a randomised trial. The Arterial Revascularisation Trial is a Medic...
