This report [1] provides extensive angiographic and intravascular ultrasound follow-up of patients having coronary ostial and left main (LM) angioplasty with a patch of the proximal right internal thoracic artery (ITA) and demonstrating excellent anatomic results at 7 to 79 months postoperatively.
Ostial stenosis represents fibro-calcific disease of the aortic wall, whereas LM disease is atherosclerotic. The prevalence of ostial stenosis was 2.7% of patients (8,509) having coronary artery bypass (CAB) and was isolated (no coronary disease) in 17% (38 of 228) [2]. Not all authors distinguish these two entities, but in the present report, 32 of 43 (74%) had ostial disease, and in Dion's series it was 24 of 49 (49%) [1].
