title: [Coronary artery bypass surgery with internal mammary artery grafts: clinical and angiographic results].
abstract: We report clinical and angiographic results of coronary artery bypass grafting (CABG) surgery in 307 patients. IMA grafts can be utilized in the wide ranges of patient ages and/or coronary lesions including left main trunk disease, and have good adaptive capability to coronary flow demand with very low probability of atherosclerotic changes. Postoperative (5.2 +/- 4.4 months) patency rates for IMA grafts and SVG were 96% and 86%, respectively; a significant difference (p less than 0.001). From the benefits of this graft, the use of IMA has become a routine procedure in our CABG surgery and the rate of multiple bypasses with IMA grafts has increased recently. The late cardiac events have significantly (p less than 0.05) decreased in patients with the IMA graft than in those without it. We believe that the use of IMA has improved the quality of CABG in Japanese patients and this operative modality can bring better late results than multivessel PTCA.
