Abstract

Midventricular Takotsubo cardiomyopathy is an atypical variant of stress-induced cardiomyopathy characterized by circumferential midventricular hypokinesia with basal and apical sparing. We present the case of a 63-year-old woman presenting with acute chest pain and elevated cardiac troponin I following emotional stress. While echocardiography initially suggested apical involvement, Photon-Counting Detector Coronary CT Angiography (PCD-CCTA) provided a comprehensive "1-stop-shop'' assessment. The high-resolution photon-counting acquisition excluded obstructive coronary artery disease, while multiphase cine reconstructions definitively characterized the midventricular wall-motion abnormalities. Diagnosis was confirmed by the complete resolution of wall-motion abnormalities on follow-up cardiac MRI. This case highlights the capability of emerging photon-counting CT technology to simultaneously assess coronary anatomy and ventricular function, facilitating the rapid diagnosis of atypical cardiomyopathy variants.
