Adrenal vein sampling is the gold standard for identification of surgically curable primary aldosteronism, but its accuracy might be hindered by blood dilution from accessory vein blood. We prospectively investigated the presence of accessory veins draining into adrenal veins and their effect on the selectivity index (SI) in 74 consecutive patients undergoing adrenal vein sampling. On the right...

INTRODUCTION The commonest variation to the classic anatomic description of renal arterial supply is the presence of accessory renal arteries. The incidence varies widely according to ethnicity. There is no data on the prevalence of these anomalies in persons of Caribbean ethnicity. METHODS All CT scans done over two years from July 1, 2010 to June 30, 2012 were retrospectively evaluated. The...

Transcatheter radiofrequency ablation of supraventricular tachycardia was first introduced in 1987. The procedure is now well-accepted as primary treatment for supraventricular tachycardia in paediatric patients. In this report we describe our experience of radiofrequency ablation of accessory pathway mediated supraventricular tachycardia in the past 10 years. From 1994 to 2005, 121 procedures ...

PURPOSE We aimed to investigate the feasibility and effectiveness of accessory hepatic vein recanalization (balloon dilatation/stent insertion) for patients with Budd-Chiari syndrome (BCS) due to long-segment obstruction of the hepatic vein. METHODS From March 2010 to December 2013, 20 consecutive patients with BCS, due to long-segment obstruction of three hepatic veins, treated with accessor...

BACKGROUND High rates of success using radiofrequency ablation energy have rapidly transformed catheter ablation from an investigational procedure to the nonpharmacological therapy of choice for symptomatic Wolff-Parkinson-White syndrome. Prior studies of radiofrequency accessory pathway ablation were based on a ventricular approach. Risks associated with prolonged arterial catheter manipulatio...

We present a case of accessory gallbladder demonstrating an anatomical variation not previously reported. While rare, accessory gallbladders are an important consideration if a cholecystectomy is to be performed. We also present a brief literature review of accessory gallbladders.

BACKGROUND Fetal and neonatal atrioventricular (AV) reentrant tachycardias can be life-threatening but resolve in most cases during the first year of life. The transient presence of accessory AV myocardial connections during annulus fibrosus development may explain this phenomenon. METHODS AND RESULTS A total of 45 human embryonic, fetal, and neonatal sectioned hearts (4 to 36 weeks of develo...

OBJECTIVES The purpose of this study was to categorize the reasons for a prolonged or failed procedure in a series of patients undergoing catheter ablation of an accessory pathway. BACKGROUND Radiofrequency ablation of accessory pathways at times requires a lengthy procedure or a second ablation session, or both, and not prior studies have systematically investigated the reasons for this. M...

Introduction. We are presenting a rare case of a patient who developed simultaneous tumors in the main parotid gland (MPG) and an accessory parotid gland (APG). The APG tumor was not recognized when the more prominent MPG tumor was excised. We will discuss the clinical features of this case. Case presentation. A 66-year-old woman was referred to our department with a painless right cheek mass. ...
