Catheter ablation of atrial tachycardia originated from the ostium of
anomalous drainage between left interior pulmonary vein and left atrial
Atrial tachycardia from the left atrium is well recognized, the common
origin was identified at mitral annulus, left atrial appendage (LAA) and
pulmonary vein (PV). However, there is no report about AT in patient
with anomalous pulmonary venous drainage. We report one case with focal
AT originating from the ostium of anomalous drainage between left
interior PV and LAA.
