Spontaneous Coronary Artery Dissection in Patients With a Provisional Diagnosis of Takotsubo Syndrome.

ABSTRACT: Background Takotsubo syndrome (TTS) mimics acute myocardial infarction in the absence of culprit coronary artery disease and is more common in women. Spontaneous coronary artery dissection (SCAD) shares a predilection for women, can result in left ventricular wall motion abnormalities similar to TTS, and may manifest subtle angiographic findings. The aim of this study was to determine the frequency of SCAD misdiagnosed as TTS. Methods and Results Coronary angiograms of patients presenting with a provisional diagnosis of TTS were retrospectively reviewed by an independent expert blinded to left ventriculography and the specific purpose of the study to assess for SCAD. TTS was defined using European Society for Cardiology criteria. SCAD was categorized according to the Saw angiographic class
