Key result
Cryoablation of the left extension of the AV node using 3D mapping and intracardiac echocardiography was successfully performed without fluoroscopy or damage to the AV node or bundle of His.
Why the study?
Can cryoablation guided by 3D mapping and intracardiac echocardiography safely treat recurrent AVNRT involving the left extension of the AV node without fluoroscopy?

Can cryoablation guided by 3D mapping and intracardiac echocardiography safely treat recurrent AVNRT involving the left extension of the AV node without fluoroscopy?
Cryoablation guided by 3D electroanatomic mapping and intracardiac echocardiography can safely and effectively treat recurrent AVNRT involving the left AV node extension without fluoroscopy.
Supports feasibility of zero-fluoroscopy cryoablation for left AVNRT extension; leaves open generalizability beyond case reports.
We present a case of successful cryoablation of the left extension of the atrioventricular (AV) node for treatment of a recurrent atrioventricular nodal reentry tachycardia without the use of fluoroscopy. Three-dimensional electroanatomic mapping system and intracardiac echocardiography were used to navigate catheters in the heart and position them according to anatomical landmarks. Due to the nature of cryoablation lesion formation, lesions were able to be applied safely in right atrium, as well as in left atrium, without damaging AV node or bundle of His.

Kalinšek et al. (2020) conducted a case report in Recurrent atrioventricular nodal reentry tachycardia (n=1). Cryoablation guided by 3D electroanatomic mapping and intracardiac echocardiography was evaluated on Successful cryoablation without damaging AV node or bundle of His. Cryoablation of the left extension of the AV node using 3D mapping and intracardiac echocardiography was successfully performed without fluoroscopy or damage to the AV node or bundle of His.
