Physiological nature of the internal mammary artery grafts.
A 4-month postoperative angiographic study of an internal mammary artery (IMA) graft illustrates its capacity to regulate flow by changes in caliber in response to changes in coronary vascular resistance. This physiological adaptability may be one of the reasons for excellent long-term results of in situ IMA grafts.
