Catheter ablation in children requires placement of multiple large femoral venous sheaths and catheters. Magnetic resonance angiography (MRA) was used to evaluate the effect of indwelling lines on femoral venous blood flow. Between October 1993 and February 1994 a total of 17 patients scheduled for catheter ablation underwent venous MRA. Two-dimensional(More)
Total anomalous pulmonary venous connection (TAPVC) has a relatively high surgical mortality, especially the infracardiac variety. A small left atrium may limit postoperative cardiac output. Superimposition of digitally subtracted angiographic (DSA) images may be used to define pulmonary venous anatomy, left atrial size, and its spatial relationship to the(More)
The influence of flecainide (0.1, 0.5, 1.0, and 2.0 µg/mL)on atrioventricular (AV) conduction was studied in neonatal and adultperfused rabbit hearts using extracellular bipolar surface electrograms andpremature atrial and ventricular pacing. Flecainide produced a concentrationand rate-related increase in the steady-state nodal conduction(AHmin and an(More)
Pre-event identification of a specific cardiac substrate abnormality in a patient is an important step in preventing sudden cardiac death (SCD) in the pediatric and adult population. Certain cardiac substrate abnormalities can render the patient "at risk" for SCD and strategies for prevention of SCD in children must involve the identification and subsequent(More)
