AIMS To investigate the natural history of mitral valve and aortic abnormalities in patients with Marfan syndrome during childhood and adolescence. METHODS Fifty two patients with Marfan syndrome were followed for a mean of 7.9 years. Occurrence of adverse cardiovascular outcomes was measured clinically and by ultrasound examination. RESULTS Mitral valve prolapse (MVP) was diagnosed in 46 p...
BACKGROUND Cardiac manifestations of Marfan syndrome include aortic root dilation and mitral valve prolapse (MVP). Only scant data exist describing MVP in patients with Marfan syndrome undergoing aortic root replacement. METHODS AND RESULTS We retrospectively analyzed data from 166 MFS patients with MVP who were enrolled in a prospective multicenter registry of patients who underwent aortic r...
OBJECTIVES The aims of this study were to determine D-shaped mitral annulus (MA) dimensions in control subjects without significant cardiac disease and in patients with moderate to severe mitral regurgitation (MR) being considered for transcatheter mitral therapy and to determine predictors of annular size, using cardiac computed tomography. BACKGROUND The recently introduced D-shaped method ...
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 remains controversial. METHODS Of 1,200 p...
FAMILIAL DYSAUTONOMIA, a rare syndrome typically involving Jewish children is probably transmitted as a simple autosomal recessive gene. 1-4 During the past 15 years, eight patients with familial dysautonomia underwent a total of 24 surgical procedures under general anaesthesia at The Hospital for Sick Children, Toronto. The purpose of this paper is to review our experience with these eight pat...
The long term results of midodrine treatment in a patient having debilitating chronic fatigue syndrome (CFS) are reported. Midodrine treatment, directed at the autonomic nervous system, resulted in correction of the dysautonomia followed by improvement of fatigue. This finding is consistent with the hypothesis that dysautonomia plays a major part in the pathophysiology of CFS and that therapies...
background: familial dysautonomia (fd) is a rare hereditary syndrome which is an autosomal recessive trait that typically affects jewish children. important signs and symptoms of the disorder include; diminished pain perception, absence of overflow tears, hypotonia, fainting cardiac arrhythmias and autonomic crisis. cases report : in this article we reported 3 cases of fd syndrome which had pre...
Understanding of the atherosclerosis process has evolved from simple plaque build-up causing blockage to inflammation and endothelial dysfunction. The underlying etiology for endothelial dysfunction and vascular inflammation is autonomic imbalance. Autonomic imbalance also causes hormonal dysregulation and cellular receptor sensitivity. Therefore, dysautonomia is the underlying etiology behind ...
