Collagen content in Sham and rTOF right ventricles. (A) Histological sections stained with Masson's Trichrome showing a greater collagen staining (blue) and a disorganised myocardial structure in the rTOF RV. (B) Collagen content was increased in rTOF RVs compared with Sham. RV endocardial activation time correlated linearly with RV-EDVi (C) and collagen content (D). Data are means±SD. *p<0.05, Sham N=4, rTOF N=4–6. ENDO, endocardial; EDVi, end-diastolic volume indexed to body surface area; rTOF, repaired tetralogy of Fallot; RV, right ventricle.
