ClinConnect Summary

We will prospectively enroll all patients that will be referred to our center for ablation of supraventricular tachycardia and will have an electrophysiologically proven atrioventricular nodal reentry tachycardia. In order to prove the mechanism specific maneuvers will be performed during induced sustained tachycardia. Navigation in the heart will be performed in a fluoroless fashion, with the use of a three-dimensional electro-anatomic mapping (3DEAM) system. Detailed anatomical definition and navigation in the area of the Koch triangle will be done with intracardiac echocardiography (ICE)...

Eligibility criteria

• Inclusion Criteria:
• • ECG or holter ECG evidence of regular narrow QRS complex tachycardia, intraprocedural pacing maneuvers in sinus rhythm and during ongoing tachycardia indicating presence of AVNRT
• Exclusion Criteria:
• • terminal or severe medical condition with expected survival of less then 12 months, deep venous thrombosis preventing access to the femoral vein, intracardiac thrombi, anatomical irregularities of pelvic veins and/or inferior vena cava, inability to induce AVNRT after the initial induction and diagnosis - enables exclusion of procedures where accidental mechanical termination of slow pathway conduction with the cryoablation catheter occurs
