Three-dimensional demonstration of total anomalous pulmonary venous return with contrast-enhanced magnetic resonance angiography.
A newborn male was hospitalized for a heart murmur and severe cyanosis after his birth. Echocardiography showed an abnormal vein crossing below the diaphragm; total anomalous pulmonary venous return (TAPVR, Darling type III) was suspected. A contrast-enhanced 3-dimensional magnetic resonance angiography (MRA) was performed on the 6th day after his birth to assess pulmonary vein stenosis. The MRA was obtained with a 1.5-T superconducting imager (Signa Horizon LX EchoSpeed, with 8.3 operating system software; GE Medical Systems, Milwaukee, WI) and a 4-channel phased array coil for the brain to optimize signal detection with the image sequence from a fast-spoiled gradient-echo (fast-SPGR) with fat suppression. Contrast medium (gadopentetate dimeglumine, 0.1 mmol/kg, Magnevist, Schering, Berlin, Germany), 0.6 mL, was administered at 0.2 mL/sec using a power injector.
