Why the study?
Epicardial adipose tissue (EAT) may contribute to idiopathic RVOT tachycardia pathophysiology through inflammatory or autonomic mechanisms, but the relationship between EAT thickness and RVOT tachycardia required investigation.
Population
55 patients with RVOT tachycardia and 60 control subjects
Comparison
Patients with RVOT tachycardia vs control subjects
Key result
Patients with right ventricular outflow tract tachycardia had significantly higher epicardial adipose tissue thickness compared to healthy controls (0.914 cm vs 0.488 cm, p <0.001).

Increased epicardial adipose tissue thickness is associated with the presence of idiopathic right ventricular outflow tract tachycardia, suggesting a potential mechanical, metabolic, or autonomic pathophysiological link.
Kahraman et al. (2021) conducted a cross-sectional in Right Ventricular Outflow Tract (RVOT) tachycardia (n=115). Right Ventricular Outflow Tract (RVOT) tachycardia vs. Healthy controls was evaluated on Epicardial adipose tissue (EAT) thickness (p=<0.001). Patients with right ventricular outflow tract tachycardia had significantly higher epicardial adipose tissue thickness compared to healthy controls (0.914 cm vs 0.488 cm, p <0.001).
