Fig 5: Correlation Between Myoarchitecture and RV Function.
Helical range was associated with key RV functional metrics (A-B) and coupling (C), but not with RV wall thickness (D). CDF: Fischer rat model; PH: pulmonary hypertension; RV: right ventricle; RVSP: right ventricle systolic pressure; RVWT: right ventricle wall thickness; SD: Sprague-Dawley rat model; SV: stroke volume; TAPSE: tricuspid annular valve plane systolic excursion; TAPSE/RVSP: measure of RV-pulmonary artery coupling. SD: n=5 Control, 5 PH; CDF: n=4 Control, 4 PH. Linear regression model.
