IRM cardiaque après ablation par RF d'une tachycardie ventriculaire

In addition to its current indications, cardiac magnetic resonance imaging (MRI) is becoming an increasingly popular tool for electrophysiology studies. Its outstanding spatial resolution provides an excellent tissue characterization, in particular before radiofrequency ablation for arrhythmia. Three interesting cases of patients with idiopathic ventricular tachycardia offered us an opportunity to demonstrate the contribution of cardiac MRI after radiofrequency ablation. This imaging method allowed us to evaluate myocardial lesions, determine their localization, size, and extension, and identify mechanic and hemodynamic complications.
