Bilateral Versus Single Internal Thoracic Artery Grafts

چکیده
PURPOSE OF REVIEW Several advances have been made in recent years to improve outcome for patients with coronary artery disease. One of the most debated topics regarding surgical treatment with coronary artery bypass grafting (CABG) is graft selection. This review aims to present the current status and scientific evidence for bilateral internal thoracic artery (BITA) grafting. RECENT FINDINGS Observational studies and pooled analyses suggest that BITA grafting is associated with improved survival. Early results from a large randomized controlled trial report safety and efficacy of the method. The improved survival might be amplified in select groups, but with an increase in sternal wound-related complications. The benefit of BITA grafts seems to remain to an approximate age of 69 years at surgery. CABG with BITA grafts is likely associated with improved long-term survival at a cost of an increase in sternal wound infections. Ten-year results from the Arterial Revascularization Trial are expected in 2018, providing the best evidence regarding the method yet. Early results show it is a safe method in most patient categories considerable for CABG.

BACKGROUND The issue of superiority of single internal thoracic artery grafting versus bilateral internal thoracic artery grafting remains unresolved. The aim of this study was to compare the long-term outcome of single and bilateral internal thoracic artery grafting with concomitant saphenous vein grafting for multivessel coronary artery bypass grafting. METHODS Between March 1985 and April ...

BACKGROUND The use of bilateral internal thoracic (mammary) arteries for coronary-artery bypass grafting (CABG) may improve long-term outcomes as compared with the use of a single internal-thoracic-artery plus vein grafts. METHODS We randomly assigned patients scheduled for CABG to undergo single or bilateral internal-thoracic-artery grafting in 28 cardiac surgical centers in seven countries....

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...

Objective. Bilateral internal thoracic artery (BITA) grafting provides improved graft patency and potential survival advantage in selected patients as compared to single left internal thoracic artery (LITA) revascularization. The ideal functional BITA configuration remains controversial. Methods. Patients undergoing planned BITA revascularization with greater than 75% stenosis in both the left ...
