*Myocardial left and right ventricle mass measured from the position of tip of the Rayflow catheter.
†Note: RV mass has been calculated as 20% of the LV mass.
CCTA, coronary CT angiography; FFR Rayflow, fractional flow reserve during continuous thermodilution (with Rayflow in situ); LAD, left anterior descending; LCX, left circumflex; LV, left ventricle; Pa, central aortic pressure; Pd, distal coronary pressure; Qnorm, normal value of coronary flow in the hypothetical absence of stenosis and infusion catheter; RCA, right coronary artery; RV, right ventricle; T, distal vessel temperature during continuous thermodilution; Ti, infusion temperature.
