Lm. Carey et al., PULMONARY-ARTERY SIZE AND FLOW DISTURBANCES AFTER PATENT DUCTUS-ARTERIOSUS COIL OCCLUSION, The American journal of cardiology, 78(11), 1996, pp. 1307
Transcatheter closure of patent ductus arteriosus with Gianturco coils
may impinge on adjacent vascular structures. The left pulmonary arter
y relative size may decrease after patent ductus arteriosus coil occlu
sion; thus, serial follow-up echocardiography is recommended to assess
long-term left pulmonary artery growth.
