Chronic Severe Aortic Regurgitation

Chronic severe AR with a wide arterial pulse pressure and preserved resting forward flow. The LV accommodates regurgitant volume without assuming pulmonary congestion at baseline.

Overview

Select Chronic Severe Aortic 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.

Chronic severe AR with a wide arterial pulse pressure and preserved resting forward flow. The LV accommodates regurgitant volume without assuming pulmonary congestion at baseline.

Aortic diastolic runoff widens pulse pressure. LVEDP can exceed mean LA/wedge pressure.

This is an isolated valve phenotype with normal PVR. Pulmonary hypertension can be added to represent a precapillary component.

Congestion is not obligatory in chronic valve disease. Add filling pressure or myocardial dysfunction to explore decompensation.

Step by step

  1. Reset interventions if you want the untreated example.
  2. Select the condition and inspect the pressure summary and relevant waveforms.
  3. Pause for annotations; add one intervention or loading change to compare the response.
