radiofrequency catheter ablation of type 1 atrial flutter

Transvenous Radiofrequency Catheter Ablation for Atrial Flutter and Atrial Fibrillation

Transvenous radiofrequency catheter ablation (RFA) for treatment of atrioventricular (AV) reentrant tachycardia and AV nodal reentrant tachycardia is remarkably successful. To the best of my knowledge, there has not been a large randomized trial comparing RFA with other treatments for these tachycardias. The lack of such trials is due at least in part to the self-evident efficacy of RFA in this...

Radiofrequency catheter ablation for the treatment of human type 1 atrial flutter.

Catheter ablation of atrial flutter using radiofrequency energy.

Sixteen patients with type I atrial flutter underwent an attempt at radiofrequency catheter ablation (8 women, 8 men, mean age 53 +/- 11 years). The primary criterion used to identify sites for radiofrequency energy delivery was the identification of a fractionated electrogram. Radiofrequency energy was delivered for 20 to 30 seconds. Radiofrequency catheter ablation was acutely successful in 1...

Radiofrequency ablation of atrial flutter.

A33-year-old man with cardiac and pulmonary sarcoidosis developed ventricular tachycardia managed with an implantable cardioverter-defibrillator and amiodarone therapy. Subsequently, episodes of atrial flutter triggered spurious therapies from the implantable cardioverter-defibrillator, and the patient underwent electrophysiological evaluation. Common atrial flutter (caudocranial septal and cou...

Symptomatic improvement after radiofrequency catheter ablation for typical atrial flutter.

OBJECTIVE To assess the changes in quality of life, arrhythmia symptoms, and hospital resource utilisation following catheter ablation of typical atrial flutter. DESIGN Patient questionnaire to compare the time interval following ablation with a similar time interval before ablation. SETTING Tertiary referral centre. PATIENTS 63 consecutive patients were studied. Four patients subsequentl...

Radiofrequency catheter ablation for atrial flutter following orthotopic heart transplantation.

A 26 year old woman with a diagnosis of limb girdle muscular dystrophy and peripartum cardiomyopathy underwent orthotopic heart transplantation using standard atrial anastomoses. Recurrent atrial flutter was demonstrated in the absence of histological evidence of cellular rejection. Radiofrequency ablation of the flutter circuit was successfully performed allowing the avoidance of long term ant...
