BACKGROUND The objectives of our study were to determine the frequency of supraventricular tachyarrhythmias (SVTAs) among modifications of the Fontan operation and identify risk factors for developing SVTA. METHODS AND RESULTS The population consisted of all patients who had any modification of the Fontan operation at the Mayo Clinic between 1985 and(More)
OBJECTIVE We characterized the histologic liver changes that occur after the Fontan operation and identified the factors associated with worsening hepatic disease. METHODS From 1979 to 2009, 33 patients who died after the Fontan operation had a postmortem analysis at our institution. The liver histologic findings were graded for sinusoidal and portal(More)
OBJECTIVE The purpose of this study was to assess the outcome of pulmonary valve replacement (PVR) in adults with moderate/severe pulmonary regurgitation after tetralogy repair, with particular emphasis on patient outcome, durability of valve repair, and improvement in symptomatology. DESIGN/SETTING/PATIENTS The project committee of the International(More)
OBJECTIVES The aim of this study was to investigate the prevalence of mitral valve prolapse (MVP) and its association with ventricular arrhythmias in a cohort with "unexplained" out-of-hospital cardiac arrest. BACKGROUND Ventricular arrhythmias are an important cause of sudden unexpected death in the young. The role of MVP in sudden unexpected death(More)
BACKGROUND Reproducible repair of Ebstein's malformation is challenging and numerous surgical techniques have been described. We reviewed our experience with the cone reconstruction. METHODS Between June 2007 and December 2011, 89 patients (47 female; 53%) underwent cone reconstruction (median age 19 years; range, 19 days to 68 years). Indication for(More)
Assessment of ventricular systolic function has been based on the geometric models of ventricular shape. This study was designed to define normal values for a nongeometric myocardial performance index (MPI) in children and to evaluate the utility of MPI in congenital heart disease. The MPI measures the ratio of total time spent in isovolumic activity(More)
Transcatheter fenestration to create an interatrial communication has been used to treat patients with protein losing enteropathy (PLE) after Fontan operation. No systematic data have been reported assessing the results of this procedure. Our institutional database was queried to identify patients after Fontan operation who had transcatheter fenestration to(More)
Percutaneous branch pulmonary artery (PA) stenting can be challenging, especially in patients with stenosis of the right ventricular (RV) outflow tract or tortuous PA branches. In these cases, a hybrid procedure deploying PA stent(s) during cardiac surgery provides an alternative to relieve branch PA stenosis. The Mayo Clinic Congenital Cardiac surgical(More)
Fetuses with congenital heart disease (CHD) have circulatory abnormalities that may compromise cerebral oxygen delivery. We believe that some CHD fetuses with decreased cerebral oxygen supply have autoregulation of blood flow that enhances cerebral perfusion (brain sparing). We hypothesize that cerebral autoregulation occurs in CHD fetuses, and the degree(More)
OBJECTIVE To describe a multicenter experience with patent foramen ovale (PFO) and atrial septal defect (ASD) device closure for presumed paradoxical emboli in children and young adults (<35 years old). PATIENTS AND METHODS Medical records were reviewed of patients who had device closure of an ASD or PFO, who were younger than 35 years, and who had a(More)
