Intravenous prostaglandin E1 (alprostadil) bolus in ductus arteriosus-dependent CHD: valid or absolutely contraindicated?

The use of prostaglandin E1 is well documented in ductus arteriosus-dependent CHD or in neonatal pulmonary pathologies that cause severe pulmonary hypertension. The intravenous infusion is well established in loading infusion and maintenance with an onset of action of 30 minutes until 2 hours or even more. Our aim is to report three patients with pulmonary atresia that presented hypercyanotic spell due to a ductal spasm during cardiac catheterisation in whom the administration of a bolus of alprostadil reversed the spasm and increased pulmonary flow, immediately stabilising the condition of the patients allowing subsequent successful stent placement with no serious complications or sequelae after the administration of the bolus.

Transcatheter resolution of an aneurism of the pulmonary trunk with residual ductus arteriosus after thoracoscopic clipping: a new approach.

Patent ductus arteriosus is the most common cardiac anomaly in our country. In the last few decades, there has been a lot of interest in developing less invasive techniques like video-assisted thoracoscopic clipping; nevertheless, this also has some complications. We present an 8-year-old female, which had been treated with video-assisted thoracoscopic clipping of patent ductus arteriosus.
