ABSTRACT
OBJECTIVE:
To compare the relative merits between chordal shortening and artificial chordae to repair the anterior leaflet prolapses (ALP).METHODS:
The clinic data of 50 cases underwent repair of ALP from March 1990 to March 2008 were analyzed retrospectively. There were 29 male and 21 female patients with a mean age of (42.6 +/- 11.3) years old. There were 23 patients in chordal shortening group and 27 patients in artificial chordae group.RESULTS:
There were 3 operative deaths in chordal shortening group (13.0%), and 1 death in artificial chordae group (3.7%, P = 0.199). With a mean follow-up of (5.8 +/- 4.8) years and a total follow-up of 278 patient-years, there were 3 late deaths respectively in each group. According the Kaplan-Meier survival curve, the actuarial survival rate at 5-8 years was 70.0% +/- 18.2% for chordal shortening group and 86.8% +/- 9.2% for artificial chordae group (chi(2) = 8.17, P = 0.046). There were 5 reoperations, of which 4 in chordal shortening group and 1 in artificial chordae group. According to the Kaplan-Meier freedom from reoperation curve, the freedom from reoperation at 5 years was 83.3% +/- 15.2% for chordal shortening group and 100% for artificial chordae group (chi(2) = 12.06, P = 0.007). The COX proportional hazard regressions revealed that chordal-shortening technique was the independent risk predictor for the late cardiac event after ALP surgical repair.CONCLUSION:
Artificial chordae techniques has a relative superiority to chordal shortening for repair of mitral valve ALP.
