Abstract

|
|
Atrioventricular nodal reentrant tachycardia (AVNRT) is one of the most common forms of arrhythmia. The first line of treatment is typically radiofrequency catheter ablation (RFCA), though the efficacy and safety of this procedure can be limited by anatomic variations. We present two cases of patients with anatomic variations undergoing RFCA for AVNRT. These variations were: first, a diverticulum in the right atrial (RA) septum, and second, heart distortion caused by a tuberculosis-destroyed lung. Despite efforts to normalize the procedure, both variations complicated the execution of RFCA.
