The Fontan circuit is the result of a palliative surgical procedure that is performed in patients with a functionally single ventricle cardiac anomaly. The success of this operation has resulted in an increasing population of adults with this anatomy and physiology. The purpose of this article is to familiarize the general radiologist with the expected(More)
OBJECTIVES The Fontan procedure provides palliation for patients with complex congenital heart disease. A late complication is the development of a pro-arrhythmogenic environment. Modifications to the surgical technique try and reduce the incidence of late arrhythmia. This study aims to establish incidence and outcome of arrhythmias in Fontan patients with(More)
Chronic hypoxia leads to a greater degree of pulmonary hypertension in the Wistar-Kyoto (WKY) rat than in the Fischer 344 (F-344) rat. We questioned whether this difference is associated with baseline differences in pulmonary artery anatomy, a greater degree of hypoxia-induced pulmonary vascular remodeling in the WKY rat, and/or differences in expression of(More)
INTRODUCTION The right ventricle (RV) supports the systemic circulation in patients who have had an intraatrial repair of transposition of the great arteries or have congenitally corrected transposition. There is concern about the ability of a systemic RV to support the additional volume load of pregnancy, and previous studies have reported deterioration in(More)
OBJECTIVE   Adult patients with a Fontan circulation tend to have diminished exercise capacity. The principal objective of this study was to investigate the safety of the endothelin receptor antagonist bosentan in Fontan patients, and, secondarily, to assess effects on cardiovascular performance, New York Heart Association functional classification (NYHA(More)
We present the case of a 22-year-old man with a Fontan circulation who suffered from intractable protein losing enteropathy for an 8-year period necessitating several hospital admissions for recurrent pleural effusions and edema. Despite trying several recognized medical therapies to alleviate his protein losing enteropathy, his condition did not improve(More)
OBJECTIVES To report procedural outcome and short-term follow-up data for the Gore septal occluder (GSO), a new device for closure of patent foramen ovale (PFO). BACKGROUND Transcatheter closure of PFO is an established treatment modality but no current device provides a perfect solution. The GSO has a number of design features, which make it potentially(More)
BACKGROUND Paravalvular leak (PVL) occurs in 5% to 17% of patients following surgical valve replacement. Percutaneous device closure represents an alternative to repeat surgery. METHODS All UK and Ireland centers undertaking percutaneous PVL closure submitted data to the UK PVL Registry. Data were analyzed for association with death and major adverse(More)
 The mechanism of the grey baby syndrome produced by chloramphenicol overdose is poorly understood. The present study assessed the membrane toxicity of this agent by means of its depressant effect on excitable tissues. The inhibition by drugs of protozoan motility was used as a toxicity endpoint, measured by the swimming speed of Tetrahymena pyriformis(More)
