Coronary angiograms. The coronary angiograms of the left coronary (a) and right coronary arteries (c). A totally occluded lesion in the proximal left anterior descending artery ① was treated with drug-eluting stent on the day of hospitalization. The diffuse stenosis in the right coronary artery ② was also treated with drug-eluting stents on the following day. The remaining lesions of the proximal and middle segments of the left circumflex artery were treated with drug-eluting stents on day 7 of hospitalization ③. Coronary angiograms after the successive treatments (b and d). Note the disappearance of the collateral vessel ④ to the right coronary artery via the atrial circumflex branch of the left circumflex artery after successful revascularization of the right coronary artery
