Transcoronary chemical ablation of ventricular tachycardia.

چکیده
Transcoronary chemical ablation of ventricular tachycardia was recently performed in one patient with refractory ventricular tachycardia in our hospital. The procedure was successful. The arrhythmia was cured and no recurrence occurred in a 24-month period. The clinical application and mechanism of transcoronary chemical ablation were discussed.

Transcoronary Chemical Ablation of Ventricular Tachycardia
After identification of the artery supplying blood to the arrhythmogenic area, transcoronary chemical ablation of ventricular tachycardia was undertaken in three patients with incessant tachycardia in whom the other therapeutic options had failed. Sterile ethanol (96%) was given at a dose of 1.5 ml in two patients and a total of 6 ml in the third. The arrhythmia was cured in two patients and su...
متن کاملTranscoronary Ethanol Ablation For Ventricular Tachycardia
RRadiofrequency catheter ablation is a well established modality of treatment for ventricular tachycardia (VT). But it may not be successful in certain cases when the re-entrant circuit is situated deep within the myocardium and inaccessible to both endocardial and epicardial ablation. One of the earliest reports on transcoronary ethanol ablation of refractory ventricular tachycardia was by Ino...
متن کاملRole of alternative interventional procedures when endo- and epicardial catheter ablation attempts for ventricular arrhythmias fail.
BACKGROUND Ventricular tachycardia (VT) refractory to antiarrhythmic drugs and standard percutaneous catheter ablation techniques portends a poor prognosis. We characterized the reasons for ablation failure and describe alternative interventional procedures in this high-risk group. METHODS AND RESULTS Sixty-seven patients with VT refractory to 4±2 antiarrhythmic drugs and 2±1 previous endocar...

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...
متن کاملUnconventional warfare: Successful ablation of ventricular tachycardia by direct ventricular puncture in a patient with double mechanical heart valves
Introduction Catheter ablation of ventricular tachycardia (VT) has improved dramatically over the last 2 decades, with the introduction of new mapping and ablation technologies. The use of epicardial access and transcoronary ethanol ablation (TCEA) has been an important innovation to target arrhythmogenic substrate that is not accessible from the standard endocardial approach. Mechanical heart ...
