BACKGROUND The survival rate to discharge after a cardiac arrest in a patient in the pediatric intensive care unit is reported to be as low as 7%. The survival rates and markers for survival strictly regarding infants with cardiac arrest after congenital heart surgery are unknown. METHODS AND RESULTS Infants in our pediatric cardiac intensive care unit(More)
The overall risk of pediatric cardiac catheterization remains low despite the enormous new complexity and potential for complications brought on by the growth of interventional catheterization techniques. For all patients aged < 21 years, balloon interventions carry the highest risk, diagnostic procedures carry more risk than non-balloon interventions, and(More)
As the volume and complexity of catheter ablation of atrial fibrillation (AF) continue to rise, there is increasing attention directed at reducing exposure to ionizing radiation. This has led to the emergence of intracardiac echocardiography (ICE) as a stand-alone imaging modality guiding AF ablation. In addition to directing transseptal puncture, ICE may(More)
Transcatheter patent foramen ovale (PFO) closure has been undertaken to eliminate paradoxical emboli as a cause for recurrent strokes/transient ischemic attacks (TIAs). We report the results of investigations to determine causes of all significant focal neurologic events (FNEs) after PFO closure reported to our center. Records of 216 consecutive patients(More)
We report angiographic findings in an infant with congestive heart failure due to a large right coronary artery to right ventricular fistula who underwent surgical ligation. Repeat catheterization 2 years later unexpectedly showed extensive thrombosis of the right coronary artery with multiple recanalized channels supplying the right coronary distribution.(More)
BACKGROUND Off-label use of transcatheter aortic and pulmonary valve prostheses for tricuspid valve-in-valve implantation (TVIV) within dysfunctional surgical tricuspid valve (TV) bioprostheses has been described in small reports. METHODS AND RESULTS An international, multicenter registry was developed to collect data on TVIV cases. Patient-related(More)
OBJECTIVE Determine prevalence and associations with pulmonary hypertension (PH) in preterm infants. STUDY DESIGN Prospective institutional echocardiographic PH screening at 36 to 38 weeks' corrected gestational age (GA) for infants born <32 weeks' GA who had bronchopulmonary dysplasia (BPD; group BPD), and infants without BPD who had a birth weight (BW)(More)
Late sequelea following a Mustard operation for transposition of the great arteries (TGA) include atrial arrhythmias and dysfunction of the systemic right ventricle. Catheter mapping and ablation of atrial tachycardia in the setting of significant right ventricular dysfunction may result in hemodynamic compromise. We report the novel use of the Impella(More)
OBJECTIVE Critically ill children with cardiac disease often require prolonged central venous access. Thrombosis of systemic veins or the need to preserve vessels for future cardiac procedures limits sites for placement of central venous catheters in these patients. This study evaluates the use of Broviac placement via the transhepatic approach for this(More)
Percutaneous pulmonary valve perforation in selected neonates with pulmonary valve atresia and intact ventricular septum has been well established as a therapeutic option. Pulmonary valve perforation is associated with significant risks including perforation of the right ventricle. Optimal catheter positioning is crucial to the success of the procedure.(More)
