Catheter ablation is indicated for the management of supraventricular tachycardias (SVTs). We investigated the effect of sex on short-term outcomes after catheter ablation for SVTs other than atrial fibrillation (AF). Using the Healthcare Cost and Utilization Project Nationwide Readmission Database for the years 2016-2018, SVT patients who underwent catheter ablation were identified using the appropriate International Classification of Diseases, 10th Revision, codes. The primary outcome was 30-day readmissions. Secondary outcomes included 30-day readmissions for SVT, postprocedural bleeding, acute myocardial infarction, transient ischemic attack, stroke, hemopericardium, cardiac tamponade, length of stay (LOS) in the hospital, and total hospital charges (in USD). Female sex was not associated with an increased risk of the primary outcome (P = .168) but was associated with a significantly decreased risk of postprocedural revascularization (P = .001), LOS (P = .003), and total hospital charges (P = .002). There were no significant differences in other secondary outcomes. Among patients admitted for catheter ablation for SVTs (other than AF), female sex was associated with decreased LOS and total hospital charges, which may be attributed to increased comorbidity rates in men and gender-based biases.
