“De Winter” pattern in patients with non-ST-segment elevation acute coronary syndrome

Abstract

“De Winter” pattern was first described by Robbert J. de Winter in 2008. It is an electrocardiographic sign characterized by ST-segment depression of 1-3 mm, in precordial leads (V1-V4), with a high and symmetrical T wave in the same leads, associated with ST-segment elevation in aVR, which represents a severe lesion of the proximal left anterior descending artery. The case report presented corresponds to 22-year-old man who came to the emergency department with the mentioned electrocardiographic changes; in the coronary angiography is confirmed the presence of a severe, occlusive lesion (100%), of ostial location, in the left anterior descending artery, on which a percutaneous transluminal coronary angioplasty was successfully performed.
