Heartache In Adolescence - Non-invasive Tissue Characterization With Cardiovascular Magnetic Resonance

摘要

A 15-year-old boy admitted with chest pain, and raised levels of Troponin I but normal viral titres, was treated acutely for presumed myocarditis. Several months later, cardiovascular magnetic resonance (Fig. 1) demonstrated a dilated and impaired left ventricle, with an ejection fraction of 42%, and normal proximal coronary arteries. Late gadolinium enhancement, indicative of myocardial damage, suggested ventricular scarring, but T2-weighted Short Ti Inversion Recovery images, which give evidence of oedema in acute myocarditis, werernnormal.
