Dual-loop intra-atrial reentry in humans.
BACKGROUND Dual-loop atrial reentrant tachycardias have not been clinically described. METHODS AND RESULTS Five patients (3 men, 2 women; mean age, 48+/-16 years) were studied 24+/-15 years after surgical closure of an ostium secundum atrial septal defect for drug-resistant atrial tachycardia. Complete tachycardia mapping was performed in the right atrium with multipolar catheters and a 3-dim...
متن کاملA dual-loop bi-atrial macro-reentry flutter during atrial fibrillation ablation.
Dual-loop macro-reentry atrial flutter (AFL) is an atypical AFL, which has two loops of the reentry circuit usually localized within single atrium. In this case report, we present a double-loop bi-atrial flutter during atrial fibrillation ablation, in which the two reentry circuit loops were located around the inferior vena cava (IVC) and the mitral annulus, (MA) respectively.
متن کاملElectroanatomical mapping and ablation of upper loop reentry atrial flutter.
Upper loop reentry is a rare type of non isthmus-dependent atrial flutter with a reentry circuit around the superior vena cava. We present a case of atrial flutter of this type in a 75-year-old man with concomitant sick sinus syndrome. The diagnostic approach used three-dimensional electroanatomical mapping with the upgraded ENSITE 3000 system. This is the first case to be described where, apar...
متن کاملDemonstration of intra-atrial conduction delay, block, gap and reentry: a report of two cases.
REENTRY HAS BEEN FREQUENTLY proposed as a mechanism for a variety of cardiac arrhythmias. For certain types of arrhythmias, the role of reentry appears well established.1 10 While intra-atrial reentry has long been suspected as a mechanism of some form of atrial arrhythmias, the phenomena of interor intra-atrial reentry in man have rarely been documented.8 11 The inability to demonstrate intero...
متن کاملRight atrial flutter due to lower loop reentry: mechanism and anatomic substrates.
BACKGROUND The mechanisms of an atrial flutter (AFL) that is more rapid and at times more irregular than typical AFL are unknown. METHODS AND RESULTS Twenty-nine patients with AFL were studied. Atrial electrograms were recorded from a 20-pole catheter placed against the tricuspid annulus (TA), with its distal electrodes lateral to the isthmus between the TA and the eustachian ridge (ER), and ...
