BACKGROUND The arterial switch operation is the preferred treatment for transposition of the great arteries (TGA), but there are concerns on the fate of the neoarterial trunks. METHODS Ninety-three children were reviewed for functional and morphologic assessment of both reconstructed arteries after the arterial switch operation. Longitudinal analysis(More)
OBJECTIVES The optimal timing of the Fontan staging for a univentricular heart and its impact on growth remains debateable. In a Fontan cohort, the influence of staged interventions and patient factors on somatic development was explored. METHODS We reviewed 64 total cavopulmonary connection (TCPC) patients treated since 1992. Serial anthropometric(More)
The progeny of mothers treated with lincomycin during the first, second, or third trimester of their pregnancy were extensively evaluated at various periods extending to 7 years after birth. As compared to a control group (mothers not receiving lincomycin), the study group did not show any more developmental anomalies of the teeth, specific physical(More)
This study aimed to study differences in lung function after surgical and percutaneous atrial septal defect (ASD) closure. Several studies have demonstrated abnormalities of pulmonary function in adults and children with ASD. These abnormalities persist even a few years after correction. This study compared pulmonary function between patients who underwent(More)
OBJECTIVE Follow-up after tetralogy of Fallot (ToF) repair is directed to detect timely right ventricular (RV) dysfunction by following pulmonary regurgitation and global RV size, with little attention for the effective contribution of regional RV dysfunction. This study investigates the contribution of regional RV dysfunction on exercise capacity after ToF(More)
BACKGROUND Aortic dilation and dissection contribute highly to the increased mortality of Turner syndrome (TS) but the exact pathophysiology is not completely understood. DESIGN Prospective case - control study. METHODS 15 prepubertal TS girls (median age 10.64, IQ 8.31-11.04) with a tricuspid (TAV, n=9) or a bicuspid (BAV, n=6) aortic valve, and 31(More)
Even after successful treatment of aortic coarctation, a high risk of cardiovascular morbidity and mortality remains. Uncertainty exists on the factors contributing to this increased risk among which are the presence of (1) a residual narrowing leading to an additional resistance and (2) a less distensible zone disturbing the buffer function of the aorta.(More)
OBJECTIVE To investigate whether the duration of pleural drainage after Fontan completion operations can be influenced by postoperative lisinopril administration or can be related to water balance hormone levels. METHODS In a prospective trial 21 patients scheduled for total cavopulmonary connection were randomized into two groups, with group I receiving(More)
