Key result
Arterial conduits, especially LIMA, offer superior long-term patency as the preferred choice for CABG.
Why the study?
Choosing appropriate bypass conduits is important for long-term outcomes after surgical revascularization, prompting a current review of available conduit choices in coronary artery bypass surgery.
What are the available choices of conduits in coronary artery bypass surgery and their respective properties?
What are the available choices of conduits in coronary artery bypass surgery and their respective properties?
The internal mammary artery remains the preferred conduit for coronary artery bypass grafting due to its superior biological properties and long-term patency.
Supports IMA preference in CABG; leaves open need for randomized comparisons of novel conduits.
Choosing appropriate bypass conduits is important in the consideration of long-term outcomes after surgical revascularization. When deciding on a grafting strategy, attention should be given to technical, anatomic, and angiographic determinants of conduit properties, as well as the clinical characteristics of the patient. The aim of the study was to present a current review of available choices of conduits in coronary artery bypass surgery. To date, only 4 conduits have proven to be effective: the saphenous vein (SVG), the internal mammary arteries (IMAs), the radial artery (RA), and the right gastroepiploic artery (RGEA). The IMA has unique biological properties that confer protection to intimal growth and atherosclerotic plaque formation, making it the conduit of choice for coronary artery bypass grafting. SVG exhibits a lower patency rate than those of IMAs. The RGEA allows revascularization of the inferior wall but is less commonly used, given that it is more prone to spasms.

Panagiotopoulos et al. (2023) conducted a review in Coronary artery disease. Arterial and venous conduits was evaluated. Arterial conduits, particularly the left internal mammary artery, demonstrate superior long-term patency rates and are the preferred choice for coronary artery bypass surgery.
