Split right coronary artery and shepherd's crook course of direct origin of the conal artery: An unhitherto association in a case of rheumatic mitral stenosis.

In a 47-year-old lady, planned for redo percutaneous mitral commissurotomy for recurrent mitral valve stenosis, there was incidental detection of splitting of right coronary artery and direct origin and shepherd's crook course of the conal artery. Though these two anomalies have no hemodynamic significance, correct nomenclature and potential clinical implications have been described.

Postoperative intrapulmonary invagination of the left internal mammary artery-An anomalous course deciphered on CT angiography.

We hereby present a case of intrapulmonary invagination of the left internal mammary artery detected on CT angiography. We aim to highlight the role of CT angiography in identifying these course anomalies and their clinical implications.

An unusually long intra-atrial course of the right coronary artery detected on CT angiography.

We hereby present an unusually long intra-atrial course of the right coronary artery incidentally detected on computed tomography angiography. Although usually asymptomatic, an intra-atrial right coronary artery may be injured during iatrogenic procedures which require right heart catheterisation.

Coexistence of carotid trunk and aberrant right subclavian artery originating close to left subclavian artery in tetralogy of fallot-A rare aortic arch branching anomaly.

We hereby present a patient with tetralogy of Fallot in whom a carotid trunk and aberrant right subclavian artery (arising just next to the origin of the left subclavian artery) were diagnosed on computed tomography (CT) angiography. We aim to highlight the role of CT angiography in identifying these rare aortic arch branching anomalies, which are crucial information for the operating surgeon.

Venous vascular ring-A rare congenital venous anomaly in a patient of tetralogy of Fallot.

We hereby present a case of tetralogy of Fallot with duplicated brachiocephalic vein having a preaortic and a subaortic component. We aim to highlight the role of computed tomography angiography in identifying these rare associations of tetralogy of Fallot.

A rare case of tetralogy of Fallot-pulmonary atresia with absent right pulmonary artery and anomalous origin of left pulmonary artery from ascending aorta.

We report a case of a 5-year-old child with tetralogy of Fallot-pulmonary atresia with anomalous origin of left pulmonary artery from ascending aorta and right lung supplied by collateral arteries. This case highlights the role of preoperative CT angiography in differentiating this entity from a common arterial trunk with discontinuous pulmonary arteries.

Double aortic arch with partially atretic left arch detected on CT angiography in a case of double-chambered right ventricle: A rare association.

We report an 11-year-old child with double-chambered right ventricle detected on echocardiography in whom computed tomography (CT) angiography revealed a rare arch anomaly double aortic arch with atretic left arch. This case highlights the ability of CT angiography in identifying such cardiovascular anomalies which have clinical and surgical implications.

Pulmonary Arterial Dilatation: Imaging Evaluation Using Multidetector Computed Tomography.

Pulmonary artery dilatation comprises a heterogeneous group of disorders. Early diagnosis is important as the presentation may be incidental, chronic, or acute and life threatening depending upon the etiology. Cross-sectional imaging plays an important role, with CT pulmonary angiography being regarded as the first line investigation in the evaluation of pulmonary artery pathologies. Moreover, effects of pulmonary artery lesions on proximal and distal circulation can also be ascertained with the detection of associated conditions. Special attention should also be given to the left main coronary artery and the trachea-bronchial tree as they may be extrinsically compressed by the dilated pulmonary artery. In context of an appropriate clinical background, CT pulmonary angiography also helps in treatment planning, prognostication, and follow-up of these patients. This review mainly deals with imaging evaluation of the pulmonary arterial dilatations on CT with emphasis on the gamut of etiologies in the adult as well as pediatric populations.

"Dual Drainage" in the mixed variety of totally anomalous pulmonary venous connection.

We report a case of 6-week-old boy with a mixed variety of totally anomalous pulmonary venous connection where the common channel had a dual drainage into the coronary sinus and left brachiocephalic vein respectively. The case also highlights the role of preoperative computed tomography angiography in demonstrating the exact pulmonary venous anatomy, course and identifying obstruction, when present.

Incidental detection of calcified left coronary artery pseudoaneurysm years after surgery for TOF.

We present images from computed tomography angiography in a 40-year-old female with a calcified pseudo-aneurysm in her left coronary artery, who had previously undergone repair of tetralogy of Fallot.
