Which artery is commonly used as a graft for Minimally Invasive Direct Coronary Artery Bypass Grafting (MIDCABG)?

The internal thoracic artery, also known as the internal mammary artery, is the preferred choice for grafting in Minimally Invasive Direct Coronary Artery Bypass Grafting (MIDCABG) procedures. This artery is a robust blood vessel that provides an excellent long-term patency rate for coronary artery bypass grafting. Its location allows for easier access during minimally invasive techniques, ultimately reducing recovery time for patients.

Moreover, the internal thoracic artery has an optimal size and blood flow characteristics that make it suitable for coronary arterial bypass. During bypass operations, it is often used to supply blood to the areas of the heart that are affected by blockages in coronary arteries, therefore improving myocardial perfusion.

While arteries like the radial, femoral, and carotid can also be used for grafting in other types of cardiac surgical procedures, they are not commonly utilized in the context of MIDCABG compared to the internal thoracic artery. The radial artery could be used in other types of bypass surgeries, but the internal thoracic artery is favored due to its reliability and the surgical advantages it provides in minimally invasive access.
