BACKGROUND Information on comparative outcome between radiofrequency catheter ablation (RFA) and antiarrhythmic drugs (AADs) >1 year after randomization is important for clinical decision-making. METHODS AND RESULTS A total of 198 patients (age, 56 ± 10 years) with paroxysmal atrial fibrillation were randomly assigned to RFA (99 patients) or to AADs (99 patients). We evaluated efficacy of RFA...
AIMS In patients with sick sinus syndrome, bradycardia can be treated with a single-lead pacemaker or a dual-chamber pacemaker. Previous trials have revealed that pacing modes preserving atrio-ventricular synchrony are superior to single-lead ventricular pacing, but it remains unclear if there is any difference between single-lead atrial pacing (AAIR) and dual-chamber pacing (DDDR). METHODS A...
BACKGROUND Single-shot ablation techniques may facilitate safe and simple pulmonary vein isolation to treat paroxysmal atrial fibrillation. Multielectrode pulmonary vein isolation versus single tip wide area catheter ablation-paroxysmal atrial fibrillation is the first multinational, multicenter, prospective, noninferiority randomized clinical trial comparing multielectrode-phased radiofrequenc...
An 86-year-old woman presented with a 1-week history of worsening dyspnea, wheezing, orthopnea, and paroxysmal nocturnal dyspnea. She denied chest pain, cough, or fever. She did not smoke cigarettes. Her past medical history included bioprosthetic aortic and mitral valve replacement for severe mitral stenosis and aortic regurgitation, paroxysmal atrial fibrillation, and rheumatoid arthritis. He...
A37-year-old man with frequent episodes of paroxysmal atrial fibrillation refractory to antiarrhythmic therapy (and no other documented arrhythmias on multiple Holter examinations) underwent an attempt at radiofrequency ablation of the atrial fibrillation. Catheter positions are shown in the left anterior oblique view in Figure 1 and include 2 catheters in the left and right upper pulmonary vei...
Background—Information on comparative outcome between radiofrequency catheter ablation (RFA) and antiarrhythmic drugs (AADs) 1 year after randomization is important for clinical decision-making. Methods and Results—A total of 198 patients (age, 56 10 years) with paroxysmal atrial fibrillation were randomly assigned to RFA (99 patients) or to AADs (99 patients). We evaluated efficacy of RFA or A...
A 31-year-old woman underwent elective transthoracic echocardiography for paroxysmal atrial fibrillation, which showed a large left atrial mass. A two-dimensional echocardiogram showed a large left atrium mass. Subsequent transesophageal echocardiography showed a 3 cm x 3 cm circular mass with smooth contours. The differential diagnosis included myxoma versus thrombus, but because of morphology...
