Remifentanil is a mu-opioid receptor agonist with a context sensitive half-time of 3 min and an elimination half-life < or = 10 min. This study sought to evaluate the efficacy of remifentanil and propofol total intravenous anesthesia (TIVA) in 161 patients undergoing inpatient surgery. Remifentanil 1 microgram/kg was given intravenously (i.v.) followed by(More)
OBJECTIVE This study aims to analyse the collective experience of participating European Congenital Heart Surgeons Association centres in the surgical management of complications resulting from trans-catheter closure of atrial septal defects (ASDs). METHODS The records of all (n=56) patients, aged 3-70 years (median 18 years), who underwent surgery for(More)
BACKGROUND Radiofrequency catheter ablation (RCA) of supraventricular tachycardia (SVT) in children is highly successful but requires exposure to radiation. Nonfluoroscopic mapping systems may significantly reduce fluoroscopy time. METHODS Forty consecutive pediatric patients who underwent RCA for accessory pathways (AP) or AV nodal reentrant tachycardia(More)
BACKGROUND Chylothorax after congenital heart surgery (CHD) is a potentially challenging complication. The purpose of this study was to review our experience with the management of chylothorax following congenital heart surgery. METHODS Between September 1997 and August 2006, of 1341 pediatric patients undergoing correction of congenital heart disease in(More)
OBJECTIVES Right ventricular (RV) dysfunction is a significant cause of morbidity and mortality after surgical correction of tetralogy of Fallot (TOF). Transatrial/transpulmonary repair avoids a ventriculotomy (in contrast to the transventricular approach) emphasizing maximal preservation of RV structure and function. We have adopted this technique as less(More)
OBJECTIVES This study analyzes the results of the arterial switch operation for transposition of the great arteries in member institutions of the European Congenital Heart Surgeons Association. METHODS The records of 613 patients who underwent primary arterial switch operations in each of 19 participating institutions in the period from January 1998(More)
OBJECTIVE Since most centers' experience with Ebstein anomaly is limited, we sought to analyze the collective experience of participating institutions of the European Congenital Heart Surgeons Association with surgery for this rare malformation. METHODS The records of all 150 patients (median age 6.4 years) who underwent surgery for Ebstein anomaly in the(More)
Surgical repair of Tetralogy of Fallot (TOF) is followed by very good early and medium-term results (perioperative mortality < or =5%), but there is increasing awareness of the occurrence of late adverse events: many patients experience progressive right ventricular (RV) dilatation/dysfunction leading to symptomatic right ventricular failure, arrhythmias,(More)
Occlusion of secundum atrial septal defects (ASD) by means of percutaneous transcatheter systems is increasingly used in clinical practice. A variety of different types and models of septal occluder devices are available nowadays, amongst which the Amplatzer device (Amplatzer Medical, Golden Valley, MN, U.S.A.), is regarded as one of increasing popularity.(More)
