Exercise Stress Echo (Pulmonary pressure) Rest Peak dPmax = 64 mmHg dPmax = 110 mmHg

Exercise Stress Echo (Mitral Regurgitation) Rest Peak Aliasing velocity = 38.4 cm/s PISA radius = 0.5cm Peak MR velocity = 500cm/s VTI MR = 175cm ERO = 2 x 0.92 x 38.4 / 570 = 0.12cm2 Regurgitant volume = 175 x 0.12 = 21ml Aliasing velocity = 38.4 cm/s PISA radius = 0.9cm Peak MR velocity = 570cm/s VTI MR = 195cm ERO = 2 x 0.92 x 38.4 / 570 = 0.34cm2 Regurgitant volume = 195 x 0.34 = 66ml
