Atrioventricular nodal reentry tachycardia (AVNRT) is the most common arrhythmia in electrophysiology laboratory. The classical approach to the treatment is ablation of slow or fast pathway with right approach. In 3% of cases, conventional classical approach is insufficient and tachycardia recurs again. In aggressive right-hand side ablation, AV block can be seen. Experience with AVNRT ablation with left approach is limited. The aim of this study was to examine the results of the early ablation of typical AVNRT with the left approach.
150 patients with typical AVNRT ablation by conventional methods in electrophysiology laboratory were included in the study. The average age of the patients was 43.2±2.6. 12. In 12 patients (8%) recurrence was observed immediately after the procedure. With retrograde aortic approach left posteroseptal radiofrequency (RF) energy was given to all 12 cases. The rhythm of the intersection in all cases observed. RF energy is until you return to sinus rhythm. Tachycardia with programmed stimulation was induced in none of the patients. One month later, none of the patients had any symptoms.
As a result, when typical AVNRT ablation with conventional methods is failed, left approach AVNRT ablation is an effective method.
