Pulmonary Atresia with Ventricular Septal Defect without Major Aorto-Pulmonary Collateral Arteries: Echocardiography and the Role of Computed Tomography and Magnetic Resonance Imaging.

Pulmonary atresia with ventricular septal defect (PA-VSD) is usually diagnosed by transthoracic or fetal echocardiography, with the prenatal diagnosis being feasible and accurate if fetal cardiology services are available. The limitations of transthoracic echocardiography (TTE) in the evaluation of PA-VSD include the complete evaluation of the pulmonary arteries and patent ductus arteriosus, quantitative evaluation of the right ventricle size and function, and delineation of associated cardiac anomalies such as coronary artery anomalies, anomalies of systemic or pulmonary venous return, and complex arch anomalies. Echocardiography also has limitations in evaluating hemodynamics such as flow volumes, shunts, and regurgitant fraction.

The presentation of pulmonary vasculature in pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries (PA/VSD/MAPCA) is highly variable-as is the number, size and position of the MAPCAs and their relationship with the native pulmonary artery system. The priority in the management of this disease should be attaining timely and complete unifocalization, as opposed to single-stage full repair in every case. The merit of early unifocalization is that it secures the pulmonary vascular bed by (a) avoiding loss of lung segments from progressive stenosis/atresia of MAPCA origins, (b) preventing lung injury from high pressure/flow in areas fed by large, unobstructed MAPCAs, and (c) restoring central continuity of the pulmonary vasculature.

Collateral vascular arteries from the descending aorta to the pulmonary arteries are uncommon after arterial switch operation. We describe a case of transposition of the great arteries (TGA) with significant aortopulmonary collateral vessels causing management difficulties after an arterial switch operation. Preoperatively, the presence of collaterals exacerbated aortic diastolic runoff and led to myocardial ischemia.

Complete transposition of the great arteries is a common life-threatening complex cyanotic congenital heart disease in infants, resulting in the operation usually performed about one week after birth. However, little is known about the surgical strategy and experience of transposition of the great arteries with an intact ventricular septum in older patients. Herein, we present an abandoned 7-year-old boy with severe cyanosis with clubbed fingers and toes and then diagnosed with transposition of the great arteries with an intact ventricular septum, atrial septal defect, patent ductus arteriosus, and pulmonary hypertension.
