Initial experience with a new flexible and adjustable mitral annulopla
sty ring is described. Used in conjunction with standard techniques of
mitral valve repair, this ring was implanted in 21 consecutive patien
ts undergoing elective operation for mitral regurgitation. Satisfactor
y valve repair was feasible in 20 of these patients. Once the ring was
sewn in place, adjustment of the ring to reduce or eliminate residual
regurgitation was beneficial in 9 patients. Excellent results were ac
hieved as determined by intraoperative transesophageal echocardiograph
y. Comparable late results were found in all but 1 patient up to 1 yea
r after repair. This patient required mitral valve replacement 6 month
s after repair due to failure of papillary muscle reconstruction. The
BiFlex ring has the merits of a flexible prosthesis with the advantage
of easy adjustment once secured in place.
