Typical Echocardiographic Findings in Different Types of Mitral Regurgitation
Type of Mitral Regurgitation | Mitral Regurgitation Jet Direction | Mitral Leaflet Motion | Left Ventricular Function |
|---|---|---|---|
Primary (intrinsic valve pathology) | Eccentric | Increased (myxomatous leaflets) Decreased (rheumatic) | Initially normal |
Secondary (non-ischemic or global ischemic changes) | Central | Decreased Symmetrically tented | Globally reduced |
Secondary (regional ischemic changes focal) | Eccentric | Decreased Asymmetrically tented | Regionally reduced (focal scar due to coronary occlusion) |
Secondary (atrial functional due to atrial fibrillation) | Central | Normal | Initially normal |
