Overview
Select Acute Severe Mitral Regurgitation under Clinical controls → Valves. The bold italic live label confirms the active selection. These are the preset’s teaching features; combined disease, rate and interventions can change the resulting numbers.
Abrupt regurgitation into a relatively noncompliant left atrium produces high wedge pressure, a large v wave and reduced forward output.
Acute MR can cause pulmonary edema without chronic chamber enlargement.
An eccentric jet directed toward a right pulmonary vein can cause unilateral, often right upper lobe edema. The CXR preset illustrates right-predominant bilateral edema.
The wedge mean can substantially exceed LV end-diastolic pressure; a v wave is not a measure of regurgitant severity.
