Multi-Modality Imaging Approach in a Challenging Case of Surgically Corrected Partial Anomalous Pulmonary Venous Return and Atrial Tachycardia Treated With Radiofrequency Ablation
Abstract:Pulmonary anomalous venous return (PAPVR) is defined as a congenital anomaly in which at least one but not all of the pulmonary veins abnormally drain into a systemic vein or directly into the right atrium. Signs and symptoms related to this condition are due to the hemodynamic abnormalities secondary to left-to-right shunt and the possible presence of other associated cardiac anomalies (e.g., sinus venous atrial septal defect). Therefore, depending on the extent of the shunt, the clinical presentation of PAPV… Show more
“…Compared to these diagnostic studies, a CECCT scan is helpful for postoperative evaluations to clearly demonstrate the anatomy by the reconstruction of 3-D volume rendering images, helping understand the repairs and anatomy with patency or occlusion of the connected pulmonary veins, septal defect closure, and LSVC. Data processing and the exact formation of multidimensional images in CECCT can be time-consuming, but reconstructed images are extremely invaluable in planning and assessing the surgery [ 9 ].…”
Here, we present a case of partial anomalous pulmonary venous return with the superior type of sinus venosus atrial septal defect. This case also had unusually persistent left-sided superior vena cava, which could not be diagnosed well in preoperative transthoracic echocardiography and required contrast-enhanced cardiac computed tomography scanning for proper diagnosing, operative planning, and avoidance of intraoperative problems. Postoperative, cardiac computed tomography scanning was also done to confirm adequate management.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
