CINE-MAGNETIC RESONANCE IMAGING OF COR-TRIATRIATUM

Two adult patients with cor triatriatum, which was shown by echocardio graphy and magnetic resonance imaging (MRI) using both spin-echo and c ine-MR techniques, are presented. Spin-echo MRI clearly demonstrated a n anatomical relationship between the membrane and pulmonary veins or left atrial appendage, which was not clear on transthoracic echocardio graphy. In addition, cine-MRI depicted abnormal now through the fenest ration of the anomalous membrane (case 1 and 2) and shunted flow throu gh the associated atrial septal defect (case 2).
