Abnormal origin of the left subclavian artery from the left pulmonary artery in a patient with double outlet right ventricle.

Lee Y, Hong SW - Korean J Thorac Cardiovasc Surg (2014)

Bottom Line: Anomalous aortic origin of the left subclavian artery (LSCA) from the left pulmonary artery (LPA) is a rare congenital cardiac malformation.We describe a case of LSCA from the LPA via ductus arteriosus in association with a double-outlet right ventricle, which never has been reported previously in Korea.

Anomalous aortic origin of the left subclavian artery (LSCA) from the left pulmonary artery (LPA) is a rare congenital cardiac malformation. We describe a case of LSCA from the LPA via ductus arteriosus in association with a double-outlet right ventricle, which never has been reported previously in Korea.

Preoperative three-dimensional 64-row multidetector computed tomography showed the LSCA arising from LPA via PDA. LSCA, left subclavian artery; LPA, left pulmonary artery; PDA, patent ductus arteriosus; LCCA, left common carotid artery; RCCA, right common carotid artery; RSCA, right subclavian artery.

Figure 1: Preoperative three-dimensional 64-row multidetector computed tomography showed the LSCA arising from LPA via PDA. LSCA, left subclavian artery; LPA, left pulmonary artery; PDA, patent ductus arteriosus; LCCA, left common carotid artery; RCCA, right common carotid artery; RSCA, right subclavian artery.

Mentions: Two-dimensional echocardiography demonstrated the right aortic arch, anterior malalignment ventricular septal defect, overriding aorta (60%), and pulmonary and infundibular stenosis. These findings were consistent with DORV, Fallot type. Patent ductus arteriosus (PDA) arose from a tortuous abnormal artery with bidirectional shunting. The left subclavian artery (LSCA) was not seen arising from the aorta. However, three-dimensional 64-row multidetector computed tomography (MDCT) showed the LSCA arising from the left pulmonary artery via ductus arteriosus (Fig. 1). Associated non-cardiac anomalies were also determined and included inguinal hernia, polydactyly, and syndactyly. The fluorescent in situ hybridization test was positive for the DiGeorge syndrome (22q11 deletion).
