“…[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.…”

“…A diverticulum was seen on CT arising from the left ventricular outflow tract coursing between the ascending aorta and RV-PA conduit and compressing the conduit. A small area of hypoattenuation (asterisk) suggestive of thrombus is also seen within the diverticulum of obstruction [79][80][81][82]. Post-repair, CT is a preferred modality to assess recurrent pulmonary venous obstruction, which can occur in up to 18% of patients ( Fig.…”

Purpose of Review To discuss the role of cardiovascular computed tomography (CT) in diagnosing and managing a spectrum of cyanotic congenital heart defects before and after repair and to review practical imaging considerations in patients with specific cyanotic lesions. Recent Findings As CT technology has rapidly advanced and radiation doses have dramatically decreased, cardiovascular CT has provided a lower-risk, high-quality alternative to diagnostic cardiac catheterization or cardiac magnetic resonance imaging (MRI) and has been increasingly utilized in nearly every type of cyanotic congenital heart defect. Summary Cardiovascular CT can provide rapid, high-resolution images to aid in preoperative planning and postoperative surveillance of cyanotic heart disease. To optimize each study, protocols should be carefully tailored to specific defects and to each patient's unique clinical and hemodynamic considerations.

Evaluation of complex congenital heart disease (CHD) demands obtaining detailed and specific information regarding cardiac chambers, connections, muscle contractility and quantification of the flow across valves, septal defects and collaterals. Plain radiography remains starting point and mainstay as a global assessment tool in pre and postoperative evaluation of the patients. Echocardiography initiates detailed investigative process, guided by clinical questions. If additional information is needed [1][2][3][4], MRI provides most precise information required for preoperative and post-operative evaluation for CHD. MDCT is a valid alternative with some limitations (inadequate functional information, radiation dose and contrast related complications), essentially providing structural information necessary for surgical management. CT evaluation also provides details about pulmonary anomalies, structural information regarding lungs, secondary complications and evaluation of tracheo-bronchial compression. CT also provides detailed mapping of collateral vasculature, information about postoperative status of surgical procedures, grafts and bony changes in association with CHD [5][6][7][8]. Integrated multimodality approach is required for, the management of the complex CHD, often decided in consultation with a multidisciplinary team consisting of paediatric cardiologist, cardiac surgeon and an imaging specialist. Table/Fig -3a&b,4] is the most common congenital cyanotic heart disease, beyond the neonatal period, accounts for 6-10% [9]. Predominant pathology of TOF is the outflow narrowing of the right ventricle and varying degree of the narrowing of pulmonary artery and branches. Other components include ventricular septal defect and overriding of aorta. Plain radiography typically shows upturned cardiac apex due to right ventricular hypertrophy. (Coeur en Sabot cardiac configuration) Lungs show varying degree of oligemia reflecting the extent of pulmonary outflow obstruction. Prominent right aortic arch is noted in up to 25% of patients. Reconstitution of a pulmonary vascularity is achieved by systemic collaterals and left to right shunting at the ductal level. The goal of surgical procedures in TOF is to increase the capacity of the right ventricular outflow by surgical correction and increase pulmonary flow. Palliation in the form of systemic to pulmonary shunt is performed for increasing the capacity of pulmonary arteries in staged procedures.Imaging requirement is to demonstrate the extent and severity of narrowing of pulmonary outflow and arteries, demonstration of associated anomalies and showing extent of pulmonary atresia or discontinuity. Measurement of right ventricular volume is very critical for staged reconstruction of outflow. MRI is the procedure of choice for functional assessment although MDCT offers accurate anatomical information in this regard [10]. Evaluation of coronary artery anomaly, exclusion of large conus branch in the region of outflow and demonstration of anomalous right coronary from LAD...

Non-ECG-gated MDCTA of infracardiac total anomalous pulmonary venous connection in neonates and young infants

Abstract: For infracardiac TAPVC, non-ECG-gated MDCTA is superior to TTE and can facilitate the preoperative evaluation when combined with TTE.
