OBJECTIVES In this study we report our preliminary results and intermediate-term follow-up (up to 3.5 years) of stent implantation for coarctation of the aorta (COA). BACKGROUND Balloon angioplasty has gained acceptance as a modality of treatment for COA. Some patients do not respond optimally to balloon angioplasty alone. Balloon-expandable stents have(More)
BACKGROUND Pulmonary vein stenosis has recently been recognized as a complication of radiofrequency ablation for atrial fibrillation. This study evaluates the presentation of affected patients and the role of transcatheter therapy for this patient population. METHODS AND RESULTS This study used a retrospective review of data from 19 patients (age, 51+/-13(More)
BACKGROUND The outcome of patients with corrected transposition of the great arteries (CTGA) is variably affected by associated intracardiac defects, tricuspid valve competence, and systemic right ventricular (RV) function. The relative importance of these factors in long-term outcome has not been evaluated. METHODS AND RESULTS Since 1958, 40 patients(More)
The Amplatzer ASD occluder may be difficult to position in some patients with a large atrial septal defect (ASD) or deficiency of one or more atrial septal rims. We developed a method to modify a Mullins transseptal sheath to enhance delivery. The resulting sheath is straight and has an exit orifice essential in the side of the distal portion of the(More)
Of 31 patients who underwent transcatheter atrial septal defect occlusion with the Bard Clamshell Septal Umbrella, only 1 had a clinically significant residual atrial septal defect at a mean follow-up of 41 months. All patients were asymptomatic despite the occurrence of device arm fractures in 84% of these patients.
OBJECTIVE To assess the results of a staged surgical approach for tetralogy of Fallot with pulmonary atresia, hypoplastic or absent pulmonary arteries, and major aortopulmonary collateral arteries. METHODS We retrospectively reviewed a consecutive series of these patients from a single institution. RESULTS From July 1993 to April 2001, 46 consecutive(More)
We sought to evaluate intermediate to long-term follow-up after coronary artery fistula (CAF) closure with emphasis on thrombotic complications. Transcatheter closure (TCC) or surgical closure (SC) is the current standard of treatment for significant CAF. Incidence and risk factors of coronary thrombosis after CAF closure have not been well described.(More)
We describe a patient with severe pulmonary artery hypertension and refractory right heart failure who underwent "butterfly" stent atrial septostomy guided by intracardiac ultrasound. This technique may be superior to previously reported blade and balloon septostomy because it allows creation of an atrial septal defect of a precise predetermined diameter.(More)
BACKGROUND We manage patients with pulmonary atresia, ventricular septal defect, major systemic-to-pulmonary collateral arteries, and diminutive central pulmonary arteries with a staged approach. The first procedure is a central end-to-side aortopulmonary shunt (Melbourne shunt) intended to cause growth and development of the central pulmonary arteries. We(More)
