Key result
Catheter ablation reduces arrhythmia recurrence and implantable defibrillator therapy in patients with ischemic ventricular tachycardia, though it does not decrease mortality.
Why the study?
Does catheter ablation improve outcomes in patients with ischemic ventricular tachycardia?
Does catheter ablation improve outcomes in patients with ischemic ventricular tachycardia?
Catheter ablation reduces VT recurrence and ICD therapies in patients with ischemic VT, but does not decrease mortality.
Supports ablation for arrhythmia control in ischemic VT; leaves open mortality effects and need for prospective trials.
Catheter ablation provides a therapeutic option for decreasing episodes of ventricular tachycardia in patients with coronary artery disease. Clinical studies show improvement with catheter ablation in reducing arrhythmia recurrence and therapy from implantable defibrillators, but not in decreasing mortality. Ablation can be an important tool for patients with electrical storm. Overall, complication rates of catheter ablation are acceptable, but recurrence rates are still significant. Advances in mapping and ablation technologies could be expected to improve the success rates and reduce the mortality.
