Acute coronary occlusion after percutaneous transluminal coronary angioplasty
Acute coronary occlusion following successful percutaneous transluminal coronary angioplasty (PTCA) remains a significant problem and is responsible for a significant percentage of PTCA-related morbidity and mortality. The reported incidence varies from 2.1 % to 12.2%. The time of occurrence in most cases is within three hours of angioplasty. Intimal tears and intracoronary thrombus are important angiographic predisposing factors. Redilation appears to be an effective means of managing this complication in most patients.
