Figure 1 Magnetic resonance images (MRI) and pericardial puncture. A: Frontal axis and B: lateral views of a cardiac MRI display the situs inversus, dextrocardia, apical left ventricle pointing to the right, and the inverted position of the liver and its relation to the heart.

متن کاملEpicardial substrate and outcome with epicardial ablation of ventricular tachycardia in arrhythmogenic right ventricular cardiomyopathy/dysplasia.
BACKGROUND Efficacy of endocardial ventricular tachycardia (VT) ablation in arrhythmogenic right ventricular cardiomyopathy/dysplasia may be limited by epicardial VT, right ventricular thickening, or both. We sought to characterize the endocardial versus epicardial substrate, measure right ventricular free wall thickness, and determine epicardial ablation efficacy in patients with right ventric...
متن کاملMapping and Surgical Ablation of Focal Epicardial Left Ventricular Tachycardia
We describe a technical challenge in a 17-year-old patient with incessant epicardial focal ventricular arrhythmia and diminished LV function. Failure of ablation at the earliest activated endocardial site during ectopy suggested an epicardial origin, which was supported by specific electrocardiographic criteria. Epicardial ablation was not possible due to the localization of the origin of the v...
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 کاملSubstrate Based Ablation of Ventricular Tachycardia Through An Epicardial Approach
Ventricular tachycardia (VT) occurring late after myocardial infarction is often due to reentry circuit in the peri-infarct zone. The circuit is usually located in the sub-endocardium, though subepicardial substrates are known. Activation mapping during VT to identify target regions for ablation can be difficult if VT is non inducible or poorly tolerated. In the latter, a substrate based approa...
