Overview
Stages of Primary Mitral Regurgitation
Shown below is the able depicting stages of mitral regurgitation, adapted from 2014 AHA/ACC guidelines for management of valvular heart disease.[1]
MR: Mitral regurgitation; MVP: Mitral valve prolapse; IE: Infective endocarditis; LA: Left atrium; ERO: Effective regurgitant orifice; LV: Left ventricle; LVEF: Left ventricular ejection fraction; LVESD: Left ventricular end systolic dimension
STAGE | DEFINITION | VALVE ANATOMY | VALVE HEMODYNAMICS | HEMODYNAMIC CONSEQUENCES | SYMPTOMS |
---|---|---|---|---|---|
A | At risk of MR | ❑ Mild MVP, normal coaptation ❑ Mild valve thickening and leaflet restriction |
❑ No MR jet area or central jet area < 20% LA on doppler ❑ Small vena contracta <0.3 cm |
Absent | Absent |
B | Progressive MR | ❑ Severe MVP, normal coaptation ❑ Rheumatic valve changes with leaflet restriction and loss of central coaptation due to ❑ Previous infective endocarditis |
❑ Central jet area 20-40% LA or late systolic eccentric jet MR ❑ Vena contracta < 0.7 cm ❑ Regurgitant volume < 60 ml ❑ Regurgitant fraction <50 % ❑ ERO <0.40 cm2 ❑ Angiographic grade 1 - 2+ |
❑ Mild LA enlargement ❑ Absent LV enlargement ❑ Normal pulmonary pressure |
Absent |
C | Asymptomatic severe MR | ❑ Severe MVP, flail leaflet ❑ Rheumatic valve changes with leaflet restriction, loss of central coaptation ❑ Prior IE ❑ Thickening of leaflets in case of radiation heart disease |
❑ Central jet area > 40% LA OR holosystolic eccentric jet MR ❑ Vena contracta ≥ 0.7 cm ❑ Regurgitant volume ≥ 60 ml ❑ Regurgitant fraction ≥50 % ❑ ERO ≥0.40 cm2 ❑ Angiographic grade 3 - 4+ |
❑ Moderate to severe LA enlargement ❑ LV enlargement ❑Pulmonary hypertension present at rest or with exercise ❑ C1: LVEF > 60% and LVESD < 40 mm ❑ C2: LVEF ≤ 60 % and LVESD ≥ 40 mm |
Absent |
D | Symptomatic severe MR | ❑ Severe MVP, flail leaflet ❑ Rheumatic valve changes with leaflet restriction, loss of central coaptation ❑ Previous infective endocarditis ❑ Thickening of leaflets in case of radiation heart disease |
❑ Central jet area >40% LA OR holosystolic eccentric jet MR ❑ Vena contracta ≥ 0.7 cm ❑ Regurgitant volume ≥ 60 ml ❑ Regurgitant fraction ≥ 50 % ❑ ERO ≥0.40 cm2 ❑ Angiographic grade 3 - 4+ |
❑ Moderate to severe LA enlargement ❑ LV enlargement ❑ Pulmonary hypertension present |
❑ Decreased exercise tolerance ❑ Exertional dyspnea |
