Key result
The size of the coronary sinus and the distance between the His bundle and coronary sinus (mean 18±7 mm) increased proportionally with children's age, body weight, body length, and body surface area.
Why the study?
What is the anatomic size of Koch's triangle in children and does it correlate with body size?

p-value: p=0.01
The size of the coronary sinus and the distance between the His bundle and coronary sinus increase proportionally with children's growth, providing useful anatomic information to avoid AV node injury during ablation.
Sumitomo et al. (2007) conducted a cross-sectional in Arrhythmias requiring catheter ablation (n=53). Age and body size (somatic growth) was evaluated on Correlation of the distance between the His bundle and coronary sinus (HB-CS) with body surface area (p=0.01). The size of the coronary sinus and the distance between the His bundle and coronary sinus (mean 18±7 mm) increased proportionally with children's age, body weight, body length, and body surface area.
