Radiofrequency catheter ablation is a safe and effective treatment option for atrioventricular nodal reentrant tachycardia (AVNRT). A nonirrigated ablation catheter used in a temperature-controlled mode is traditionally used for AVNRT ablation due to the shallow lesion depth required for successful slow-pathway ablation. In this case, a nonirrigated ablation catheter established inadequate lesions to ablate the slow pathway successfully. The adoption of an irrigated contact-force ablation catheter used in a power-controlled mode was necessary to provide higher power and possibly create a deeper lesion to ablate the slow pathway successfully, thus eliminating AVNRT inducibility in this patient.

Complete Av Block

We present a case of complete atrioventricular (AV) block following slow pathway ablation for atrioventricular nodal reentrant tachycardia (AVNRT) treated only by colchicine administration. The patient’s electrocardiogram showed complete AV-block at two weeks after catheter ablation. Colchicine is effective for late-onset AV-block caused by catheter ablation for AVNRT.
