BACKGROUND Single-ring isolation of the posterior left atrium is feasible, but the incidence and mechanisms of postprocedural arrhythmias have not been described in detail. METHODS AND RESULTS The first 100 consecutive patients (58.8+/-11.2 years old, 80 male) who underwent single-ring isolation for atrial fibrillation (66 intermittent, 18 persistent, 16 long-standing persistent) were followe...

The circus movement theory of flutter has been supported by numerous theoretical, experimental, and clinical studies, but there has been little consideration of the possible participation of the specialized conduction pathways of the atria. In the present work we have studied experimental atrial flutter in relation to the behavior of these pathways, in response to elevated potassium and to surg...

trial fibrillation (AF) and atrial flutter can coexist. Their ssociation is of particular concern when considering curaive ablation. Symptoms, similar for both, are disconcerting hould either one occur after ablation. Complete cure is the oal. Right atrial (cavo-tricuspid isthmus) ablation can cure 90% of typical forms of flutter. Unfortunately, AF can ccur after flutter ablation. In contrast, ...

Introduction The Maze IV procedure during cardiac surgery is an established treatment for patients with atrial fibrillation (AF) concomitant with a mitral valve repair or replacement. Recurrent atrial tachyarrhythmias are mainly left atrial (LA) flutter, which is associated with gaps on previous surgical lesions. Herein, we report a case in which a 3-dimensional mapping system could demonstrate...

We describe two cases of fetal atrial flutter associated with severe fetal hydrops which were unresponsive to digoxin but were successfully treated with flecainide acetate. Two cases of fetal atrial flutter were identified in fetuses with severe fetal hydrops on 3rd trimester ultrasonogram(28 weeks' gestation and 30 weeks' gestation). Following failed digoxin monotherapy, flecainide acetate was...

Atrial flutter is the most frequent arrhythmia occurring in patients who have undergone orthotopic heart transplantation. We present a representative case of typical atrial flutter with counterclockwise rotation around the tricuspid ring in a female patient who had received an orthotopic heart transplant 13 years before. The arrhythmia pattern seen on the activation map (Figure 1) shows the con...

We present an 89-year-old woman with newly diagnosed atrial flutter associated with a flare of her rheumatoid arthritis (RA). She had a history of diet-controlled type 2 diabetes mellitus, hypertension, and RA and presented with lightheadedness and worsening hand pain. She was found to be in new atrial flutter with rapid ventricular response and to have an active RA flare. In addition to adequa...

The congenital type of atrial flutter has a poor prognosis when unresponsive to digoxin (Moller, Davachi, and Anderson, 1969). Recorded experience with cardioversion is limited but it has been suggested that this type of flutter is refractory to electric countershock (Rodriguez-Coronel, Sueblingvong, and Hastreiter, 1968). We report an infant with congenital heart defects and congenital atrial ...

A patient with congenital complete heart block underwent implantation of a dual-chamber pacemaker. He presented to the emergency room with fatigue and was found to be in atrial flutter. Device interrogation revealed undersensing of 5 mV flutter waves at a programmed sensitivity of 0.5 mV. Due to undersensing, mode switch did not occur. This case illustrates apparently paradoxical undersensing o...
