Diagnosis of left ventricular myxoma with cardiac magnetic resonance imaging

Ingrid Bar, MD Institut fur diagnostische und interventionelle Radiologie Klinikum Nurnberg-Sud 90471 Nurnberg, Germany Sirs: A 20-year-old man presented with palpitation without typical angina, dyspnoe, syncope and vertigo. There was no medical history and no family member had a history of syncope. ECG showed sinus rhythm, normal heart rate, normal PR interval and QRS duration, no ST-segment elevation or negative T-waves. 24-h ECG showed no pathological findings. All laboratory parameters including cardiac biomarkers were normal. Echocardiography (TTE) revealed a 21×26 mm large intracardiac tumor localized in the left ventricle (LV) attached to the anterior wall. LV diameter and function were normal. For further characterization of tumor pathology, a cardiac magnetic resonance (CMR) study was performed. Cine-CMR showed a normal size and function of the LV (EDD 153 ml, EDS 64 ml, LV-EF 59%, LV-cardiac output 4.9 l/min). CMR confirmed the echocardiographic findings: the tumor size was measured as 19×26 mm. The tumor was clearly attached to the anterior endocardium (segment 7) by a nar
