Atrial electrical remodeling has been shown after termination of atrial flutter (AFL); however, whether abnormalities persist beyond an arrhythmic episode is not known. We aimed to characterize the atrial substrate, remote from arrhythmia, in patients with typical AFL. We compared 20 patients, studied remote from episodes of typical AFL and ...

Patent foramen ovale (PFO) is associated with cryptogenic stroke, migraine headache, decompression sickness, and platypnea-orthodeoxia syndrome. Patients undergoing transesophageal echocardiography are often hypovolemic from preprocedural fasting and might not demonstrate right to left shunting owing to insufficient right atrial pressure generation, despite provocative maneuvers. We hypothesized that volume replenishment with ...

BACKGROUND: Many adult patients with secundum-type atrial septal defects (ASDs) are able to have these defects fixed percutaneously. Traditionally, this has involved an assessment of ASD size, geometry and atrial septal margins by transoesophageal echocardiography (TOE) prior to percutaneous closure. This is a semi-invasive technique, and all of the information ...
