AB-452673-2 REPEAT STANDARD ABLATION OR INTRAMURAL NEEDLE ABLATION AFTER FAILED STANDARD ABLATION FOR VENTRICULAR TACHYCARDIA

Transcoronary ethanol ablation for recurrent ventricular tachycardia after failed catheter ablation: an update.

BACKGROUND Despite substantial progress, radiofrequency catheter ablation (RFCA) fails in some patients. After encouraging results with transcoronary ethanol ablation (TCEA), we began offering TCEA routinely when endocardial and epicardial RFCA failed or a deep intramural substrate was likely. METHODS AND RESULTS Among 274 consecutive patients who underwent 408 ventricular tachycardia (VT) ab...

What 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...

Epicardial Ablation For Ventricular Tachycardia

Epicardial ablation has lately become a necessary tool to approach some ventricular tachycardias in different types of cardiomyopathy. Its diffusion is now limited to a few high volume centers not because of the difficulty of the pericardial puncture but since it requires high competence not only in the VT ablation field but also in knowing and recognizing the possible complications each of whi...

Catheter ablation for ventricular tachycardia.

Sustained ventricular tachycardia (VT) is an important cause of morbidity and sudden death in patients with heart disease.1 Implantable cardioverter-defibrillators (ICDs) terminate VT episodes, reducing the risk of sudden death. Recurrent VT develops in 40% to 60% of patients who receive an ICD after an episode of spontaneous sustained VT. A first episode of VT occurs in 20% of patients within ...
