“…The degree of left to right shunting depends upon the number of lobes that drain systemically and the presence of an associated ASD. Isolated PAPVR from a single lobe usually remains asymptomatic [45]. Both TTE and TOE may struggle to identify PAPVR, especially those veins that insert more than 2 cm cranial to the right atrium/SVC junction [46].…”

Cardiac causes of pulmonary arterial hypertension: assessment with multidetector CT

The causes of pulmonary arterial hypertension (PAH) are diverse and include multiple congenital and acquired cardiac diseases as well as diseases primarily affecting the pulmonary vasculature, lung, pleura and chest wall. The traditional role of CT in evaluating PAH includes assessment of pulmonary vasculature and lung parenchyma with limited assessment of the heart. Advances in multidetector CT technology with improved spatial and temporal resolution now permit accurate delineation of cardiac morphology. CT pulmonary angiography (CTPA) is widely utilised in the workup of patients with suspected pulmonary vascular disease and can identify both pulmonary and cardiac causes. As the initial presentation for CTPA is often precipitated by nonspecific, unexplained symptoms and therefore undertaken by a general radiologist, it is important that a systematic approach to the interpretation of these studies, including cardiac evaluation, is routinely adopted. This paper reviews the CT evaluation in pulmonary hypertension with a particular focus on the cardiac causes, their subclassification into congenital systemic to pulmonary shunts and secondary to left heart disease, and their imaging features. It emphasises the use of a systematic approach to interpretation of CTPA examinations both in patients with known PAH and those with previously unsuspected disease.

“…The advantage of CT examinations is the short duration, making intubation unnecessary even in infants. Differential diagnosis includes acquired SVC abnormalities such as extrinsic compression by tumors, enlarged lymph nodes, vascular abnormalities, invasion of the SVC by tumors, or occlusion of the SVC by a catheter-associated thrombus [17]. …”

Bilateral absence of the superior vena cava (SVC) is a very rarely detected, mainly asymptomatic congenital vascular anomaly. Though usually innocent, this anomaly may complicate cardiothoracic surgery and certain procedures like central venous catheter insertion. This SVC anomaly is poorly known, and we assume that its incidence in the general population may be higher than detected. In this paper, we summarize current knowledge on this anomaly and its clinical implications. In addition, we present a neonatal case with bilateral absence of the SVC associated with a fetal cystic hygroma. Conclusion. Totally absent SVC can cause unexpected problems during cardiothoracic surgery. Suspicion of SVC absence should arise in basic echocardiography. Our paper suggests that, like other congenital anomalies, bilateral absent SVC may be associated with a fetal cyctic hygroma.

“…The location of coronary vein branch as determined by CTA in relation to the area of latest activation has been shown to predict response versus nonresponse to cardiac CRT 7 . In addition, CTA has been demonstrated to be able to identify anomalous structures potentially affecting implant including a valve covering the CS os, CS diverticula, and left superior vena cava connection to the CS 8,9 . Visualization of the relationship between the phrenic nerve and coronary veins has also been recently demonstrated to be visualized with potential importance in avoiding diaphragmatic pacing 10 .…”
