The heart shows right ventricular hypertrophy.
Right ventricular outflow tract obstruction is demonstrated in the form of infundibular stenosis.
There is a ventricular septal defect and overriding dilated aortic root.
Both the right and left main coronary arteries arise from the anterior and posterior coronary sinus, respectively. The non-coronary sinus is at the right lateral aspect of the root. The left divides into the anterior descending and circumflex arteries. No evidence of coronary artery stenosis or aneurysmal dilatation is identified.
The post-surgical palliative shunt connecting the innominate and main pulmonary artery is patent.
There is moderate to severe stenosis at the proximal left pulmonary artery resulting to preferential blood flow into the right lung.
All pulmonary veins drain into the left atrium.
The inferior vena cava and a single superior vena cava drain into the right atrium.
Serpiginous vessels are identified in the pericarinal region and around the proximal bronchi probably from collateral vessel formation.
There are areas of atelectasis in the right lung.
