Asymptomatic partial anomalous pulmonary venous return masquerading as pulmonary vein occlusion following radiofrequency ablation.
Recent advances in the field of cardiac electrophysiology have resulted in the rapid growth of radiofrequency ablation for treatment of arrhythmias. Pulmonary vein stenosis or occlusion is a rare, but well described adverse outcome. Fortunately, the concomitant evolution of multislice computed tomography (CT) scanners has provided an excellent non-invasive method of monitoring for this complication. We recently encountered a case on multislice CT that initially appeared to be a pulmonary vein occlusion related to the procedure, but on further evaluation was found to be an asymptomatic case of partial anomalous pulmonary venous return.
