Cannulation of patent arterial duct in patients with pulmonary atresia and ventricular septal defect

Abstract

During cardiac catheterization in patients with pulmonary atresia and ventricular septal defect, cannulation of the arterial duct was attempted in 23 children via antegrade approach. It was successful in all but two children. Injection of contrast through antegradely placed catheter resulted in improved opacification of pulmonary arteries. This technique facilitated transcatheter dilation of spontaneously closed arterial duct in two children.

Preoperative evaluation of pulmonary artery morphology and pulmonary circulation in neonates with pulmonary atresia - usefulness of MR angiography in clinical routine

“…We were able to correctly describe the presence and morphology or absence of native pulmonary arteries in 93% (14/15 patients) of the investigated neonates. Non-confluent pulmonary arteries were supplied by bilateral PDAs in all cases, which has been considered a rare condition by some [17] but also recognized as quite common by others [18]. In a study by Harikrishnan et al pulmonary blood supply was provided by a PDA in 49 of 86 patients with tetralogy of Fallot and PA [19].…”

Palliative stenting of patent ductus arteriosus in older children and young adults With congenital cyanotic heart disease

“…The radial artery was used as an alternative to the axillary artery in adults. The femoral venous access was also used to cannulate the vertical duct in selected cases, especially in adult patients with vertical duct that arose proximally in the arch using a technique that we have described previously .…”

“…Angiographic demonstration of PDA was done initially with hand injections via the catheter used to engage the duct. In cases of vertical PDA arising from under surface of aortic arch, 6F Extra Back Up (EBU) catheter (Cordis corporation, Miami) was used to hook the PDA when approached from femoral venous route . For the axillary or radial artery approach, 5 or 6 F Judkins right coronary artery guiding catheter (JR4, Cordis corporation, Miami, FL) was used.…”
