[Ambulatory catheter ablation. Indications, results and risks]

Area of Science:

• Cardiology
• Electrophysiology
• Medical Procedures

Background:

• Tachycardia, a rapid heart rhythm, significantly impacts patient quality of life.
• Radiofrequency catheter ablation offers a potential treatment for various tachyarrhythmias.
• Evaluating outpatient procedures is crucial for healthcare efficiency and patient convenience.

Purpose of the Study:

• To assess the efficacy, feasibility, and safety of performing radiofrequency catheter ablation on an outpatient basis.
• To determine the success rates and complication profile of this minimally invasive procedure.
• To establish the suitability of outpatient management for patients undergoing ablation for tachyarrhythmias.

Main Methods:

• Conducted a study on 162 consecutive patients undergoing radiofrequency catheter ablation.
• Classified tachycardia mechanisms including atrioventricular nodal reentry, accessory pathways, atrial fibrillation, atrial flutter, and ventricular tachycardia.
• Monitored patients for short-term outcomes, including complications and need for hospital admission.

Main Results:

• Achieved an overall success rate of 86% in catheter ablation procedures.
• Successfully treated 148 patients on an outpatient basis, with discharge within 3 or 24 hours.
• Reported a general complication rate of 2.27%, with most cases being minor, though severe complications like pericardial tamponade and pulmonary embolism occurred.

Conclusions:

• Radiofrequency catheter ablation can be performed effectively and safely in an outpatient setting for selected patients.
• The procedure demonstrates high efficacy and a manageable safety profile for treating diverse tachyarrhythmias.
• Outpatient management of catheter ablation is a feasible and beneficial approach for improving patient care and resource utilization.
