Ductus Arteriosus in Fetal and Perinatal Life.

The ductus arteriosus represents an essential vascular structure connecting the pulmonary artery and the aorta. Over the past decades, there has been substantial advancement in our understanding of both the fundamental and clinical aspects of the ductus arteriosus. In particular, the clarification of the regulatory mechanisms governing ductal patency in critical stages such as the fetal and the perinatal period has enabled optimal management of both physiological and pathological conditions in which the ductus arteriosus plays a crucial role.

Lung recruitment before surfactant administration in extremely preterm neonates with respiratory distress syndrome (IN-REC-SUR-E): a randomised, unblinded, controlled trial.

Background: The importance of lung recruitment before surfactant administration has been shown in animal studies. Well designed trials in preterm infants are absent. We aimed to examine whether the application of a recruitment manoeuvre just before surfactant administration, followed by rapid extubation (intubate-recruit-surfactant-extubate [IN-REC-SUR-E]), decreased the need for mechanical ventilation during the first 72 h of life compared with no recruitment manoeuvre (ie, intubate-surfactant-extubate [IN-SUR-E]).

Transcatheter closure of postsurgical residual ventricular septal defects: early and mid-term results.

Background: The incidence of residual ventricular septal defects (VSDs) after surgery is 5-25%. Redo surgery is associated with higher risks.

Methods: Between January 2000 to December 2008, 170 patients underwent percutaneous VSD closure in our centre: 22(16M) of these had 23 closures for residual VSDs.

Double-outlet right ventricle in a neonate with Cantrell's syndrome.

We report a case of the association of Cantrell's syndrome with double-outlet right ventricle in a neonate.

A comparison between the early and mid-term results of surgical as opposed to percutaneous closure of defects in the oval fossa in children aged less than 6 years.

Objectives: To compare surgical as opposed to percutaneous interventional closure of isolated atrial septal defects in the oval fossa in terms of hospital stay, efficacy, and complications, and to study the respective role of the two techniques in current practice.

Methods: Between January 1998 and April 2004, 126 out of 1210 patients treated at our institution for closure of an isolated defect in the oval fossa were aged less than 6 years. The mean age of these 126 patients at procedure was 4.

Interventricular septal hematoma in ventricular septal defect patch closure.

We report a case of interventricular septal hematoma after patch closure of a perimembranous ventricular septal defect in a 4-month-old infant. On postoperative day 1, echocardiography showed a voluminous intramural hematoma causing severe thickening of the ventricular septum. Surgical revision was necessary immediately to drain the hematoma.
