Outcome Measures

Primary Outcomes (2)

Non-inducibility of Atrioventricular Nodal Reentrant Tachycardia (AVNRT)
This is determined during the procedure by performing programmed stimulation to test for the presence of AVNRT. Non-inducibility is confirmed if AVNRT cannot be induced following the ablation, indicating a successful therapeutic intervention.
During the procedure
Recurrence of supraventricular tachycardia
It is defined as any documented episode of supraventricular tachycardia, such as AVNRT, atrial fibrillation, or atrial flutter, confirmed by electrocardiographic evidence.
Within 1 year post-procedure

Secondary Outcomes (2)

Postoperative Recovery Time
Within 24 hours post-procedure
Complication Rate
Within 1 year post-procedure

SVC Approach Group

This group includes patients who underwent zero-fluoroscopy radiofrequency catheter ablation (RFCA) for atrioventricular nodal reentrant tachycardia (AVNRT) using the superior vena cava (SVC) approach. The catheter was inserted through the median cubital vein or basilic vein, navigating through the axillary vein, subclavian vein, and brachiocephalic vein to reach the SVC. The ablation procedure was performed under conscious sedation and local infiltration anesthesia, with a large-tip electrode catheter used for mapping and ablation guided by the EnSite NavX system. The ablation parameters were set at 40 W power and 50°C temperature.

Procedure: Zero-Fluoroscopy Radiofrequency Catheter Ablation

IVC Approach Group

This group includes patients who underwent zero-fluoroscopy radiofrequency catheter ablation (RFCA) for atrioventricular nodal reentrant tachycardia (AVNRT) using the inferior vena cava (IVC) approach. The catheter was inserted through the femoral vein, extending through the iliac vein to the IVC. The ablation procedure was performed under conscious sedation and local infiltration anesthesia, with a large-tip electrode catheter used for mapping and ablation guided by the EnSite NavX system. The ablation parameters were set at 40 W power and 50°C temperature.

Study Population

The study population includes adults (age \>18 years) diagnosed with AVNRT who underwent RFCA at our institution between June and October 2022. Patients were divided into two groups based on catheter access site: the SVC approach group (median cubital or basilic vein) and the IVC approach group (femoral vein). Inclusion required at least one AVNRT episode during TEAP and programmed stimulation. Exclusion criteria were reversible causes of AVNRT, other tachycardias, severe comorbidities, or contraindications for conscious sedation or local anesthesia. This setup allows comparative analysis of SVC and IVC approaches focusing on success, complications, and recovery.
