Primary MR Intervention Navigator
Evaluate ACC/AHA 2020 intervention indication and pathway guidance for primary mitral regurgitation — based on confirmed severity, symptoms, LV function, and repair feasibility.
Input
Enter available data. Partial input is supported. The navigator updates as you add information.
Severity & mechanism
MR mechanism confirmed as primary?
Severe primary MR confirmed?
Confirmed by integrated echo assessment (EROA, regurgitant volume, vena contracta, pulmonary vein flow)
Clinical status
Symptoms attributable to MR?
≤ 60% is impaired in severe primary MR — not the same threshold as a normal heart
≥ 40 mm = enlarged — intervention threshold in asymptomatic severe MR
Intervention assessment
