Retrograde coil embolization of the patent ductus arteriosus (PDA) has been reported for ducts < 3.3 mm in diameter using 5 to 5.5Fr catheters. Our objective was to assess the immediate and short-term results of anterograde transcatheter closure of the PDA using single or multiple Gianturco coils. Thirty-three patients (11 males and 22 females) underwent an(More)
Some infants with congenital diaphragmatic hernia who die after surgical correction have a transient postoperative period during which systemic oxygenation is adequate (honeymoon period), whereas others have persistent hypoxemia. Using morphometric techniques, we analyzed lung structure, especially the arterial bed, in seven infants who died within 1 week(More)
BACKGROUND The improved survival of very low-birth-weight (<1,500 g) infants justifies more aggressive attempts to treat underlying congenital heart disease than in the past. METHODS We retrospectively reviewed all catheterizations performed at our institution between January 1, 1990 and June 1, 2004 in infants weighing <1,500 g. We performed a 3:1(More)
OBJECTIVE To review the short and medium term outcome of transcatheter pulmonary valve perforation (PVP) in patients with pulmonary atresia-intact ventricular septum and non-right ventricular dependant coronary circulation (PA/IVS non-RVDCC). BACKGROUND PVP in patients with PA/IVS non-RVDCC has become more common in the past two decades. However, data on(More)
OBJECTIVE To determine the basis for cardiac consultations for pediatric patients in an academic hospital setting. METHODS The activities of the cardiology consultation service were tabulated for 12 months, from July 2001 to June 2002. Patients were identified from 4 sources, ie, a monthly log of patient encounters maintained by the consultation service,(More)
BACKGROUND Delayed diagnosis of critical congenital heart disease (CCHD) in neonates increases morbidity and mortality. The use of pulse oximetry screening is recommended to increase detection of these conditions. The contribution of pulse oximetry in a tertiary-care birthing center may be different from at other sites. METHODS We analyzed CCHD pulse(More)
BACKGROUND Experience of balloon dilation of peripheral pulmonary stenosis (PPS) in Williams syndrome (WS) is limited. METHODS AND RESULTS Catheterizations in all patients with WS undergoing therapy for PPS from 1984 to 1999 were reviewed. Criteria for successful dilation included an increase >50% in predilation diameter and a decrease >20% in ratio of(More)
