Four examples of flow convergence zone changes during systole using colour M-‐Mode. (A and B) Func3onal mitral regurgita3on (A: early and late peaks and mid-‐systolic decreases; B: early systolic peak), (C) rheuma3c mitral regurgita3on with a end-‐systolic decrease in flow convergence zone, (D) M mitral valve prolaspe (late systolic enhancement).
Three examples of various degrees of mitral regurgita3on (MR), mild (A), moderate (B), and severe (C) are provided. The regurgitant jet as well as the mitral E wave velocity increase with the severity of MR. In severe MR, the con3nuous wave Doppler signal of the regurgitant jet is truncated, triangular and intense. Notching of the con3nuous wave envelope (cut-‐off sign) can occur in severe MR. TVI, 3me-‐velocity Integral.

Outcome with medical and surgical treatment. Mitral valve surgery was eventually performed in 552 pa3ents (75%) on the basis of the following indica3ons: dyspnea/ conges3ve heart failure in 371 pa3ents (67%), pa3ent and/or physician preference in 111 (20%), LV dila3on in 17 (3%), infec3ve endocardi3s in 18 (3%), AF in 1 (0.2%), and miscellaneous reasons in the remaining 34 pa3ents (6%). The mitral valve was repaired in 78% of pa3ents and replaced in 22%.
