Figure 1 Relationship Between RVSP and Long-Axis Velocities (TSa, TEa) in Patients Without and With Restrictive RV Physiology

(A,B) Patients without restrictive right ventricular (RV) physiology; (C,D) patients with restrictive RV physiology. RVSP = right ventricular systolic pressure; TSa, TEa = tissue Doppler imaging lateral tricuspid annular peak systolic and early diastolic velocity, respectively.
