Local device infection successfully treated without pacemaker removal in a neonate: a case report.

AIMS: Local device infection is a serious complication, especially in neonates. Complete device removal is the gold standard treatment for cardiac device infection; however, in selected cases alternative strategies could be adopted. We describe a case of a 14-day-old neonate, weighing 2.5kg, who had undergone epicardial double chamber pacemaker implantation for a congenital complete atrioventricular block. The generator pocket was created in the epigastric area below the rectus abdominis. At six days after implantation, pocket infection was found; blood cultures and the transoesophageal echocardiogram were normal. Due to the low weight of the neonate, and the limited possibility of finding a new comfortable site for housing the generator far from the infected area, we opted for a conservative strategy. We successfully applied a combination of antibiotic therapy, a vacuum-assisted wound closure system (KCI, Germany) for 40 days, and then skin transfer flap from the right flank without device removal. At one-year follow-up there were no local or systemic signs of infection.

Unusual association of transposition of great arteries with infradiaphragmatic pulmonary venous return.

A 21-day-old baby with transposition of the great arteries with intact ventricular septum, infradiaphragmatic totally anomalous pulmonary venous connection, and atrial septum defect underwent combined arterial switch operation, totally anomalous venous connection repair, and atrial septum defect closure, using a right-sided approach and temporary pulmonary veins occlusion, with no postoperative and 6-months follow-up complications. Complete anatomical correction is the most conceivable treatment for this unusual pathology; right-sided approach instead lifting the heart toward the right pleural cavity to perform left atrium-to-pulmonary veins anastomosis limits heart displacement and avoids nonphysiological three-dimensional alterations; moreover, ligation and division of vertical vein allow to obtain more tissue for anastomosis; temporary occlusion of pulmonary veins while performing anastomosis is a simple procedure that allows to avoid deep hypothermic circulatory arrest or low flow systemic perfusion. Combination of these details facilitates intra- and postoperative management, especially in combined demanding cases.
