Table 4 Summary of flow patterns - number of subjects with normal flow patterns

From: 4D cardiovascular magnetic resonance velocity mapping of alterations of right heart flow patterns and main pulmonary artery hemodynamics in tetralogy of Fallot

Location Normal volunteers (N = 10)a Tetralogy of Fallot subjects (N = 11)a P-value
SVC 10 3 <0.05
IVC 8 3 <0.05
RA 10 4 <0.05
RV diastole 10 1 <0.05
RV systole 10 9 0.48
MPA 10 5 <0.05
RPA 6 1 <0.05
LPA 10 1 <0.05
  1. SVC = superior vena cava; IVC = inferior vena cava; RA = right atrium; RV = right ventricle; MPA = main pulmonary artery; RPA = right pulmonary artery; LPA = left pulmonary artery
  2. avalues reported are number subjects with normal flow, as detailed in the methods section and in Table 3.
