Electrophysiological Features of Atrial Flutter in Cardiac Sarcoidosis: A Report of Two Cases
نویسندگان
چکیده
We report two cases of systemic sarcoidosis with atrial flutter as the clinical manifestation. In one patient, who had symptoms of shorter duration, the arrhythmia was no longer inducible after a course of glucocorticoid therapy. Electroanatomical mapping in the other case revealed patchy fibrosis of the left atrial myocardium and multiple macro-reentrant circuits. Sinus rhythm could be restored with ablation of these reentrant circuits. To our knowledge, this is the first report on the demonstration of atrial scarring in a patient with sarcoidosis using 3-D electroanatomical mapping. These two cases illustrate that the inflammation of atrial myocardium is the primary mechanism of atrial arrhythmias in patients with cardiac sarcoidosis.

A Case Report of Neonatal Atrial Flutter with Poor Feeding and Tachypnea
Background: Arrhythmias in neonates are not common and usually affect newborns with a normal heart or those that suffer from structural heart disease. A malignant type of arrhythmias is supraventricular tachycardia. Meanwhile, one uncommon type of supraventricular arrhythmias is atrial flutter (AFL), which is founded upon reentry mechanisms in the atrium. The AFL may result in heart failure or ...

Introduction Radiofrequency catheter ablation (RFCA) of typical atrial flutter (AFL) is an effective and widely performed method of treatment. Confirmation of conduction block in the cavotricuspid isthmus (CTI) is the best endpoint of the procedure. Electrophysiological measurements for validation of CTI block are usually performed using 2 or 3 catheters. However, in some situations this multi-...
