Anterior, anatomic view of a common arterial trunk (CAT) as it exits the ventricular mass. The right (RPA) and left (LPA) pulmonary arteies bifurcate from a common pulmonary trunk that has a low take off from the common trunk. Note the right aortic arch (RA) that has mirror image branching of the great vessels

The right ventricular (RV) aspect of the common arterial trunk (CAT) shows the low take off of the pulmonary trunk (PT), just at the sinotubular junction. The valve is markedly dysplastic and is quadricuspid. A muscular bar along the posterior inferior rim of the ventricular septal defect (VSD) separates the tricuspid valve (TV) from the truncal valve. The ventricular septal defect appears restrictive.

This anterior anatomic view of a common arterial trunk (CAT) shows the right (RPA) and left (LPA) pulmonary arteries bifurcating well above the sinotubular junction, along with an unusually high take off of the left coronary artery (LCO). The right coronary artery arises normally and can be visualized on the epicardial surface. The right ventricle (RV) has been windowed, demonstrating the ventricular septal defect (VSD) beneath the truncal valve with a muscular rim along its posterior inferior aspect. This muscular rim separates the tricuspid valve (TV) from the truncal valve. (SCV-superior caval vein, RAA-right atrial appendage)

Posterior view of the common arterial trunk (CAT) shown in CAT3a. The right (RPA) and left (LPA) pulmonary arteries exit the common trunk adjacent to one another. The left atrial appendage (LAA) has been retracted to show the high take off the left main coronary artery (black arrows) to the right of the pulmonary arteries. It has a partial intramural course. The truncal arch descends (DA) to the left. (SCV-superior caval vein, PV-pulmonary vein)
