Radiofrequency Ablation for Post Infarction Ventricular Tachycardia
Radiofrequency ablation has an important role in the management of post infarction ventricular tachycardia. The mapping and ablation of ventricular tachycardia (VT) is complex and technically challenging. In the era of implantable cardioverter defibrillators, the role of radiofrequency ablation is most commonly reserved as an adjunctive treatment for patients with frequent, symptomatic episodes...
متن کاملCan catheter ablation cure post-infarction ventricular tachycardia?
Catheters with saline-irrigated tips have retained controlled energy delivery while allowing production of larger lesions than conventional catheters. Alternatives to radiofrequency energy like laser, ultrasound and percutaneous cryotherapy are also undergoing investigation but before energy can be delivered, localization of the site critical for maintenance of the arrhythmia is required. This ...
متن کاملReassessing noninducibility as ablation endpoint of post-infarction ventricular tachycardia: the impact of left ventricular function.
BACKGROUND Noninducibility is frequently used as procedural end point of ventricular tachycardia (VT) ablation after myocardial infarction. We investigated the influence of left ventricular (LV) function on the predictive value of noninducibility for VT recurrence and cardiac mortality. METHODS AND RESULTS Ninety-one patients (82 men, 67±10 years) with post-myocardial infarction VT underwent ...
متن کامل[Post-infarction ventricular tachycardia with a QRS complex narrower than 140 ms: characterization and catheter ablation].
Typically, sustained monomorphic ventricular tachycardia (SMVT) in patients with a previous myocardial infarction (MI) is characterized by a wide QRS complex. However, occasionally patients present with SMVT and a narrow QRS complex (N-SMVT). We studied retrospectively the incidence of N-SMVT (i.e., QRS interval <140 ms) in patients with a previous MI and inducible SMVT who underwent electrophy...
متن کاملMapping for the Target Sites of Ablation in Post-infarction Ventricular Tachycardia- Is Sinus Rhythm Sufficient?
The long road to success with radiofrequency ablation for scar-related ventricular tachycardia (VT) has taken the electrophysiologists down many unexpected paths in the last two decades. During this period, the progress in defining the pathological circuits involved in genesis of this complex tachyarrhythmia has undoubtedly improved the ablation outcome. However, empiricism still prevails as to...
