Abstract:
Background
The creation of accurate electroanatomic maps (EAM) of the left atrium and pulmonary veins is important for atrial fibrillation (AF) ablation to guide ablative lesions and improve the safety and efficacy of the procedure. Respiratory motion of the heart and the pulmonary veins affects the accuracy of these maps.
