Abstract

INTRODUCTION: Radiofrequency catheter ablation (RFA) is an interventional cardiac electrophysiologic procedure that uses heat energy for definitive management of supraventricular tachycardias. It is a class I recommendation for chronic management of most supraventricular arrhythmias. No local data exist in the incidence hospitalization for SVT and utilization of RFA for this condition. The study aimed to obtain the prevalence of hospitalization of patients with supraventricular tachycardias where RFA is utilized, including the patients’ demographic profile, length of hospitalization, and mortality rate. 

METHODOLOGY: Philippine Health Insurance Corporation claims for hospitalization from January 1, 2017, to December 31, 2018, were reviewed. Data analysis was done using median and interquartile range for continuous data, and frequency and percentage distribution for categorical data.  

RESULTS: There were 1121 and 1149 claims for hospitalization for SVTs (atrial paroxysmal tachycardia, atrioventricular paroxysmal tachycardia, nodal paroxysmal tachycardia, and junctional tachycardia) in 2017 and 2018, respectively. This represents four hospitalization claims for SVT per 10,000 of the total PHIC claims. The majority of patients were female with median age of 52 years. Only 25 and 19 patients underwent radiofrequency ablation in 2017 and 2018, respectively. The majority of these patients were male and younger with a median age of 31 years. No mortality was recorded among patients admitted for catheter ablation. 

CONCLUSION: In 2017 and 2018, hospitalization claims for SVT requiring catheter ablation were 0.04% (four hospitalization claims for SVT per 10,000 of the total claims) in both years. The majority of patients were admitted with pharmacologic therapy on discharge with very low utilization of radiofrequency ablation for long-term management.
