Fig. 6

a Mean transmitral flow tracings confirmed mitral regurgitation at dilated baseline, as well as reduced regurgitation after ring annuloplasty repair. Note the residual mitral regurgitation after repair using a flexible annuloplasty ring, as evidenced by the flow reversal during systole. b Ring annuloplasty repair restored the mean aortic and left ventricular pressures. c Primary chordal forces significantly decreased after ring annuloplasty repair. d Secondary chordal forces decreased after ring annuloplasty repair with the axis-specific mitral annuloplasty ring being associated with a favorable secondary chordal force profile compared to that of the rigid ring. Shaded regions represent standard error.
