Noninvasive assessment of left main coronary stent patency with 16-slice computed tomography.
Abstract
We investigated the ability of 16-slice computer tomography (CT) to discriminate any restenosis after left main coronary artery stenting in 29 consecutive patients. CT was able to detect all stents and analyze the lumen properly in 27 of 29 cases. With the exception of arrhythmic or heavily calcified segments, multislice CT provides a noninvasive alternative to conventional coronary angiography in the follow-up of left main angioplasty with stenting.
