Focal atrial fibrillation treated by circumferential radiofrequency catheter ablation of pulmonary vein orifice.
If catheter ablation and implanted ICD don't work, you may need this surgery.
Radiofrequency catheter ablation (RFCA) was performed on dog's and rabbit's atrium and ventricle to observe the structural alterations of heart muscle with the change of ablation energy.
At present, pulmonary vein isolation with catheter ablation is an effective treatment in patients with symptomatic atrial fibrillation refractory or intolerant to anti-arrhythmic medications.
Herein we report a case of idiopathic left ventricular tachycardia-induced cardiomyopathy treated by catheter ablation and reversed left ventricular function.
This study tested the feasibility and safety of radiofrequency (RF) catheter ablation in eliminating focal atrial fibrillation (AF) under the guidance of intracardiac echocardiography (ICE).
