Ablation of ventricular tachycardia in patients with structural heart disease.
Catheter ablation is an important therapeutic option for controlling recurrent ventricular arrhythmias in patients with heart disease. Although implantable defibrillators are generally first line therapy in this patient population, a substantial number of patients require additional therapy with either antiarrhythmic drugs, ablation, or both. Studies of mapping and ablation have produced furthe...
متن کاملSustained ventricular tachycardia in structural heart disease.
Ventricular arrhythmias are responsible for the majority of sudden cardiac deaths (SCD), particularly in patients with structural heart disease. Coronary artery disease, essentially previous myocardial infarction, is the most common heart disease upon which sustained ventricular tachycardia (VT) occurs, being reentry the predominant mechanism. Other cardiac conditions, such as idiopathic dilate...
متن کاملSafety and Feasibility of a Minimally Fluoroscopic Approach for Ventricular Tachycardia Ablation in Patients With Structural Heart Disease: Influence of the Ventricular Tachycardia Substrate.
BACKGROUND We sought to evaluate the safety and feasibility of a minimally fluoroscopic approach using the CARTOUNIVU module during scar-related ventricular tachycardia (VT) ablation. METHODS AND RESULTS Consecutive patients with structural heart disease undergoing VT ablation using the CARTOUNIVU module were prospectively included and classified depending on their VT substrate: (1) ischemic ...
متن کاملAblation of the epicardial substrate in ventricular tachycardia associated with structural heart disease: outside in or inside out?
Percutaneous epicardial access, introduced by Sosa et al. (1) in the mid-1990s, provided an important diagnostic and therapeutic approach to the recognition and management of scar-related epicardial ventricular tachycardia (VT). Since that time, the need for epicardial ablation has been reported in 10% to 15% of patients with ischemic cardiomyopathy (ICM) (2–4), 25% to 50% of patients with noni...
متن کاملEpicardial ablation of ventricular tachycardia in ischemic heart disease.
BACKGROUND Epicardial approaches have increased ablation success in nonischemic cardiomyopathy, but the use for postinfarction ventricular tachycardias (VT) is less clear. We report the findings for epicardial VT ablation in postinfarct patients. METHODS AND RESULTS Records of 444 consecutive patients with VT because of prior infarction referred for 600 catheter ablation procedures were revie...
