With the age of patients coming forward for bypass surgery showing a decline, it is logical to assume that the addition of another arterial graft- Right internal mammary artery(RIMA) should further increase the survival. A series of recent research papers have shown that the addition of RIMA to bypass other left sided arteries of the heart (circumflex system), further improves survival.
The latest issue of Annals of Thoracic Surgery has an article re enforcing the concept that in Bypass surgery two mammary arteries are better than one.
Bilateral Internal Thoracic Artery Grafting Is Associated With Significantly Improved Long-Term Survival, Even Among Diabetic Patients
