Stages

• Stage 1: Impaired Relaxation

Echocardiographic Assessment

1. Record mitral valve inflow with pulse wave Doppler between the tips of the mitral valve with a sample of 1-2mm
2. Record Pulmonary Vein Flow Velocities
3. Record Hepatic Vein Velocities in subcostal view using Pw proximal to the junction of the IVC
