Radiofrequency Catheter Ablation of Ventricular Tachycardia in Patients Without Structural Heart Disease
Background. Radiofrequency energy has been used safely and successfully to eliminate accessory pathways in patients with the Wolff-Parkinson-White syndrome and the substrate for atrioventricular nodal reentrant tachycardia. However, this form of ablation has had only limited success in eliminating ventricular tachycardia in patients with structural heart disease. In contrast, direct-current cat...
متن کاملExperience with radiofrequency catheter ablation of fascicular tachycardia.
OBJECTIVE To report experience with radiofrequency catheter ablation of fascicular tachycardia including two cases of the rare type of this arrhythmia which arises from the anterior fascicle of the left bundle branch. DESIGN Review of results of radiofrequency ablation in nine consecutive patients presenting with fascicular tachycardia. SETTING Regional cardiac centre. INTERVENTION Percut...
متن کاملRadiofrequency catheter ablation for electrical storm in a patient with dilated cardiomyopathy.
We report a case of successful radiofrequency catheter ablation in a patient with dilated cardiomyopathy, who presented with multiple, haemodynamically poorly tolerated episodes of monomorphic ventricular tachycardia, resistant to antiarrhythmic drug treatment. The ablation procedure consisted of focal ablation of three mapped left ventricular sites, using pace and activation mapping. Additiona...
متن کاملTreatment of ventricular tachycardia-induced cardiomyopathy by transcatheter radiofrequency ablation.
Catheter ablation of ventricular tachycardia was successfully performed in a patient with dilated cardiomyopathy (ejection fraction 38%) and a long history of repetitive palpitations. Holter monitoring showed ventricular tachycardia that had a left bundle branch block QRS configuration with inferior axis deviation and was present for about one third of the daytime hours. At electrophysiological...
متن کاملWhat Next After Failed Septal Ventricular Tachycardia Ablation?
Ablation of ventricular tachycardia (VT) by conventional radiofrequency ablation can be impossible if the ventricular wall at the targeted ablation site is very thick, as for example the ventricular septum. We present a case of a patient with incessant, non-sustained slow VT originating from the septal part of the lower outflow tracts. Radiofrequency catheter ablation from both ventricles as we...
