Percutaneous epicardial ablation in ventricular arrhythmias.
INTRODUCTION Reentrant circuits of ventricular tachycardia may involve not only the endocardium but also the epicardium. Epicardial ablation can be useful in these situations. OBJECTIVE The aim of this study was to assess efficacy, safety and complications in a series of consecutive patients who underwent ablation of ventricular tachycardia with epicardial mapping. METHODS The study include...
متن کاملUnusual complications of percutaneous epicardial access and epicardial mapping and ablation of cardiac arrhythmias.
BACKGROUND Percutaneous epicardial access and mapping/ablation of cardiac arrhythmias are being increasingly performed. Although complications such as pericardial effusion are relatively common, other unusual complications may occur due to the complex anatomic architecture of the heart and surrounding tissues. In this report, we report a series of rare and unusual complications related to percu...
متن کاملPercutaneous epicardial ablation of ventricular arrhythmias arising from the left ventricular summit: outcomes and electrocardiogram correlates of success.
BACKGROUND Percutaneous epicardial ablation of ventricular arrhythmias arising from the left ventricular summit is limited by the presence of major coronary vessels and epicardial fat. We report the outcomes of percutaneous epicardial mapping and ablation of ventricular arrhythmias arising from the left ventricular summit and the ECG features associated with successful ablation. METHODS AND R...
متن کامل[Percutaneous epicardial radiofrequency ablation of idiopathic ventricular tachycardia].
We describe 3 patients with ventricular tachycardia in whom epicardial ablation was done after prior attempts of endocardial ablation had failed. Clinical ventricular tachycardia originated at the right ventricular outflow tract in one patient and near the mitral annulus in another patient. In these two cases ventricular tachycardia was mapped and successfully ablated with a percutaneous subxip...
متن کاملEpicardial Radiofrequency Ablation Failure During Ablation Procedures for Ventricular Arrhythmias: Reasons and Implications for Outcomes.
BACKGROUND Radiofrequency ablation (RFA) from the epicardial space for ventricular arrhythmias is limited or impossible in some cases. Reasons for epicardial ablation failure and the effect on outcome have not been systematically analyzed. METHODS AND RESULTS We assessed reasons for epicardial RFA failure relative to the anatomic target area and the type of heart disease and assessed the effe...
