Multidetector CT evaluation of total anomalous pulmonary venous connections: comparison with echocardiography

Abstract

MDCT can facilitate the diagnosis of TAPVC in certain cases.

Assessment of pulmonary veins after atrio-pericardial anastomosis by cardiovascular magnetic resonance

“…In a study by Oh et al, multidetector CT and echocardiography were compared in their ability to identify the drainage site of the common PV in TAPVC as well as to detect stenosis of the PVs and vertical vein [24]. Compared to their gold standard, direct detection at the time of surgery, the investigators found that echocardiography had a sensitivity of only 71% for identifying stenosis of the vertical vein in comparison to CT which had a sensitivity of 100% [24].…”

Infracardiac type total anomalous pulmonary venous return with obstruction and dilatation of portal vein

“…However, the infracardiac type is the most frequent (78%) [1], [3], [13], [14]. This type of TAPVR is characterized by obstruction located at the level of the diaphragm, caused by an extrinsic narrowing, resulting in a pulmonary edema appearance with normal cardiac silhouette in conventional imaging [1], [3], [6], [12].…”

“…Also, computed tomography allows for the performance of 3-dimensional reconstructions for advanced spatial and anatomic orientation [4], [6]. Reported sensitivities and specificities for MDCT for depicting the drainage site, areas of stenosis of the vertical vein, and the course and caliber of the anomalous vessel is 100% [4], [13]. As a disadvantage, MDCT uses ionizing radiation, which is why, in these patients, dose modulation must be adjusted to the neonatal body-weight parameters [4].…”

Computed Tomography Imaging in Patients with Congenital Heart Disease Part I: Rationale and Utility. An Expert Consensus Document of the Society of Cardiovascular Computed Tomography (SCCT)

“…[137][138][139][140][141][142] Systemic venous anomalies are also well visualized by cardiovascular CT. [143][144][145] Cardiovascular CT has also been shown to accurately visualize congenital aortic anomalies including interrupted aortic arch and aortic coarctation in both pediatric and adult patients. [146][147][148][149][150][151][152][153] It is particularly useful for evaluation of the aortic arch after endovascular intervention (stent or stent graft) where aneurysm, aortic wall injury or recurrent arch obstruction are relatively common.…”
