Aim. This study reports on the results and safety of a simplified method of trans-septal catheterization for radiofrequency catheter ablation of cardiac arrhythmias. Method and Results. Over 5 years, 411 patients underwent trans-septal catheterization for radiofrequency catheter ablation: 388 patients had a left-sided accessory pathway, 19 a left-sided focal atrial tachycardia, two atrial fibrillation and two post-infarction ventricular tachycardia. All but one patient with ventricular tachycardia underwent elective trans-septal catheterization. In the absence of a patent foramen ovale, puncture of the atrial septum was performed by using an 8F Mullins sheath and a Brockenbrough needle, according to the simplified method described in this paper. Trans-septal catheterization was accomplished in 383/388 patients (98.7%,); in 41 patients a second trans-septal catheterization and radiofrequency catheter ablation was performed for initial failure or recurrence. Radiofrequency catheter ablation was successful in 96% of accessory pathway patients, 90% of atrial tachycardia patients, in both patients with atrial fibrillation and in both patients with ventricular tachycardia. No complication related to trans-septal catheterization was observed. Conclusion. In experienced hands and according to the method described in this paper, the elective use of trans-septal catheterization for radiofrequency catheter ablation in a large cohort of patients with cardiac arrhythmias is feasible, safe and allows successful ablation in the vast majority of the patients.

Abstract

Aim. This study reports on the results and safety of a simplified method of trans-septal catheterization for radiofrequency catheter ablation of cardiac arrhythmias. Method and Results. Over 5 years, 411 patients underwent trans-septal catheterization for radiofrequency catheter ablation: 388 patients had a left-sided accessory pathway, 19 a left-sided focal atrial tachycardia, two atrial fibrillation and two post-infarction ventricular tachycardia. All but one patient with ventricular tachycardia underwent elective trans-septal catheterization. In the absence of a patent foramen ovale, puncture of the atrial septum was performed by using an 8F Mullins sheath and a Brockenbrough needle, according to the simplified method described in this paper. Trans-septal catheterization was accomplished in 383/388 patients (98.7%,); in 41 patients a second trans-septal catheterization and radiofrequency catheter ablation was performed for initial failure or recurrence. Radiofrequency catheter ablation was successful in 96% of accessory pathway patients, 90% of atrial tachycardia patients, in both patients with atrial fibrillation and in both patients with ventricular tachycardia. No complication related to trans-septal catheterization was observed. Conclusion. In experienced hands and according to the method described in this paper, the elective use of trans-septal catheterization for radiofrequency catheter ablation in a large cohort of patients with cardiac arrhythmias is feasible, safe and allows successful ablation in the vast majority of the patients.
