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...

BACKGROUND AND OBJECTIVES Ventricular fibrillation (VF) can inadvertently occur during electrophysiologic study (EPS) or catheter ablation. We investigated the incidence, cause, and progress of inadvertently developed VF during EPS and catheter ablation. SUBJECTS AND METHODS We reviewed patients who had developed inadvertent VF during EPS or catheter ablation. Patients who developed VF during...

SUMMARY Bannayan-Riley-Ruvalcaba syndrome is a congenital disorder characterized by macrocephaly, intestinal polyposis, lipomas, and pigmented macules of the penis. There is limited published radiologic literature on the syndrome. The purpose of this study was to review the brain MR imaging findings in Bannayan-Riley-Ruvalcaba syndrome as well as to compare and contrast the findings with other ...

Patients with long QT syndrome can sometimes present with a ventricular fibrillation (VF) storm. Catheter ablation of culprit premature ventricular complexes responsible for the triggering of the VF episodes may be required in rare cases of electrical storm that do not respond to conventional measures, and this can be life-saving. We describe a case of emergency catheter ablation in a young wom...

sjogren-larsson syndrome (sls) is an inherited autosomal recessive neurocutaneous disorder with congenital ichthyosis, spastic diplegia or quadriplegia and mental retardation. we report a case of sjogren-larsson syndrome with clinical profile (mental retardation, ichthyosis, spastic diplegia) and mri findings such as seen in multiple sclerosis (ms). so this rare syndrome can be another differen...

Arrhythmogenic cardiomyopathy (ACM) is a group of arrhythmogenic disorders the myocardium that are not caused by ischemic, hypertensive, or valvular heart disease. The clinical manifestations ACMs may overlap those dilated cardiomyopathy, complicating differential diagnosis. In several ACMs, ventricular tachycardia (VT) has been observed at an early stage, regardless severity Therefore, prevent...

BACKGROUND There are a paucity of data about the long-term natural history of adult Wolff-Parkinson-White syndrome (WPW) patients in regard to risk of mortality and atrial fibrillation. We sought to describe the long-term outcomes of WPW patients and ascertain the impact of ablation on the natural history. METHODS AND RESULTS Three groups of patients were studied: 2 WPW populations (ablation:...

purpose: hidden caries is a term used to describe occlusal dentine caries that is missed on a visual examination, but can be detected by bitewing radiographs. the aim of this study is the review of new studies about this lesion and presentation the ways for diagnosis, prevention and treatmen of this lesion. review of literature: investigations believe that the etiology of this lesion is the mor...

Wolff-Parkinson-White Syndrome (WPW) is a term referring to Louis Wolff who published an article in 1930 that describes 11 patients suffering from episodes of tachycardia with characteristic ECG findings (ECG pattern shows bundle branch block and shortened P-R interval). In 1943, anatomical accessory pathway of conducting tissue has been described that bypasses the atrioventricular (AV) conduct...
