Overview
Select Left Atrial Myxoma 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.
Selected mobile left atrial myxoma with intermittent mitral inflow obstruction. LA pressure rises upstream while LV filling and beat stroke volume vary; displayed reference pressures and CO are multi-beat means.
A mobile pedunculated mass can prolapse through the mitral valve and arrest in early diastole, producing a tumor plop; this sound is variable and not universal.
Obstructed beats retain more blood upstream and have less LV filling and forward stroke volume. The repeatable eight-beat mobility pattern is an illustrative substitute for positional variability, not a simulated posture or syncope event.
The native mitral valve is not assumed stenotic. Coexisting MS adds a separate fixed obstruction; valve procedures do not remove the tumor.
Embolization, tumor growth, surgery and acute complete valve occlusion are not modeled. Echocardiography establishes the mass anatomy clinically.
