房室結節性再突入頻拍（AVNRT）の再発に対して，透視検査を行わずに房室結節左延長部の凍結切除を成功させた1例を紹介する．3次元(3D)電気解剖学的マッピング(EAM)システムと心臓内エコー検査(ICE)を用いて、心臓内のカテーテルをナビゲートし、解剖学的ランドマークに基づいてカテーテルを配置した。クライオアブレーション病変形成の性質上、左心房だけでなく右心房でもAVノードやHis束を損傷することなく、安全に病変を適用することができた。この論文は著作権で保護されています。無断転載を禁じます。

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 (AVNRT) without the use of fluoroscopy. Three dimensional (3D) electroanatomic mapping (EAM) system and intracardiac echocardiography (ICE) 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.
