Successful Catheter Ablation of Focal Left Atrial Tachycardia Originating From the Mitral Annulus Aorta Junction

Focal left atrial tachycardias (AT) originating from the mitral annulus-aorta (MA-Ao) junction are rare and their mechanisms are unclear. We report a 35-year-old male with successful ablation of an exercise-induced focal AT due to triggered activity originating from the MA-Ao junction. The AT occurr...
