Clinical and electrophysiological characteristics, and relatively benign outcome, of typical atrioventricular nodal reentrant tachycardia in children and adolescents.

Background: Atrioventricular nodal re-entrant tachycardia is an uncommon arrhythmia in children. The natural history of this disturbance is poorly known in young patients.

Methods: We analyzed the clinical and electrophysiological features, and the final outcome, in 19 children affected by typical atrioventricular nodal re-entrant tachycardia diagnosed by a transoesophageal electrophysiological study.

Patent ductus arteriosus and left coronary ostium stenosis: an hybrid approach.

Nowadays combination of surgical procedures and interventional cardiology has been increasingly reported in literature for the treatment of coronary artery diseases. To confirm the applicability of such an approach we present a case where several approaches could be considered. A 56-year-old lady with incidental finding of patent ductus arteriosus (PDA) and concomitant left main coronary artery ostium stenosis was scheduled to have PDA transcatheter closure and surgical angioplasty of the coronary ostium.

Use of a novel anticoagulation strategy during ECMO in a pediatric population: single-center experience.

We describe a novel anticoagulation strategy with continuous intravenous antithrombin infusion and intermittent heparin infusion in pediatric population during extracorporeal membrane oxygenation (ECMO). From November 2004 through February 2006, 11 patients required ECMO for postcardiotomy cardiorespiratory failure. The mean duration of support time was 112 hours (range 68-192 hours).

DIDECMO: a new polymethylpentene oxygenator for pediatric extracorporeal membrane oxygenation.

We reviewed the performance of a new polymethylpentene oxygenator (DIDECMO, Dideco, Mirandola, Italy) in terms of clinical safety and efficiency in priming, oxygenation, and oxygenator resistance in neonatal and pediatric extracorporeal membrane oxygenation (ECMO) patients. Between March 2005 and January 2006, 14 patients required ECMO in the San Vincenzo Hospital. Of these, 8 (median age, 9 days; range, 3 days to 15 months) received normothermic ECMO for postcardiotomy heart failure after surgery for congenital heart disease.

Pulsatile ECMO and VAD: a dual use of a new device in pediatric cardiac patients.

The purpose of this investigation was to present the first European clinical experience with the new MEDOS DELTASTREAM DP1 used in pulsatile extracorporeal membrane oxygenation (ECMO) or ventricular assist device (VAD) options in the pediatric population. Between January 2002 and April 2006, 11 patients required ECMO and 5 patients received a left VAD (LVAD) in the San Vincenzo Hospital. Indications were postcardiotomy heart failure in 15 patients and fulminant myocarditis in one patient.

A method for chest drainage after pediatric cardiac surgery: a prospective randomized trial.

Objectives: The purposes of this study were to evaluate the clinical safety and efficacy of 10F, 15F, and 19F Blake drains (Ethicon, Sommerville, NJ) in a pediatric population after cardiac surgery and to compare their clinical effect with that of conventional chest drains.

Methods: From January 2002 through December 2004, a prospective randomized trial was conducted on 189 patients who underwent surgical intervention for congenital heart disease at our institution. Statistical analyses were conducted to test the null hypothesis that there was no difference in the incidence of pericardial or pleural effusion requiring drainage.

Initial European clinical experience with pulsatile extracorporeal membrane oxygenation.

Background: Extracorporeal membrane oxygenation (ECMO) for post-cardiotomy heart failure in neonates and infants still carries high mortality and morbidity rates. In this study we present the first European clinical experience with the Medos DeltaStream DP1, a new pulsatile flow pump, in neonates and infants.

Methods: The DP1 is an extracorporeal rotary blood pump.

Pulsatile ECMO in neonates and infants: first European clinical experience with a new device.

This study presents the first European clinical experience with the Medos DeltaStream DP1, a new pulsatile flow pump, in neonates and infants. Between January 2002 and December 2004, 420 patients at our institution underwent congenital heart surgery on cardiopulmonary bypass. During this period, 10 patients required extracorporeal membrane oxygenation (ECMO) support for acute postcardiotomy heart failure.

Acute respiratory insufficiency and giant coronary artery aneurysm with fistula.

Several causes of acute respiratory insufficiency have been reported in the literature. We describe a case in which it was caused by a rare combination of a giant right coronary artery aneurysm with fistula that occurred in a 56-year-old woman with concomitant congenital hypothyroidism. Diagnostic tools, differential diagnosis, surgical techniques, and follow-up at 1 year are discussed.
