The relationship between epicardial adipose tissue and premature ventricular contractions originating from different areas in the right ventricular outflow tract: A cross-sectional study
Cross-sectional data shows increased epicardial adipose tissue in PVCs from the RV outflow tract, indicating its different impact by BMI and sex.
Key Points
This study explores the link between epicardial adipose tissue and premature ventricular contractions originating in the right ventricular outflow tract.
Retrospective enrollment of PVC patients undergoing catheter ablation.
Categorization based on mapping results: RVOT septum and RVOT free wall groups.
EAT volume and density quantified using chest CT images.
Comparison stratified by sex, age, and body mass index (BMI).
127 PVC patients included: 77 with septal RVOT origin, 50 with free-wall origin.
Free wall group had significantly higher EAT volumes than septum group (P = 0.021; P = 0.040).
No significant EAT density differences between groups.
Larger EAT volumes in females and patients with BMI < 23 in the free wall group.
