Abstract
Background Atrial fibrillation (AF) is the commonest sustained arrhythmia afflicting the adult population. Identifying and ablating triggers in the left atrium (LA) or more often the pulmonary veins (PV) with radiofrequency energy to restore sinus rhythm is fast becoming the mainstay of treatment. The success of the procedure often requires a combination of imaging techniques with an electroanatomical mapping system. We describe the use of three dimensional (3D) delayed enhancement cardiovascular magnetic resonance imaging (DE-MRI) to provide a road map of the anatomy as well as regions of scar tissues in the LA and PV for AF ablation.
