ABSTRACT
OBJECTIVES:
To explore the feature of the edge-to-edge technique and its effect for mitral regurgitation due to myxomatous degeneration.METHODS:
The in-patient data and follow-up outcomes of 58 patients after the edge-to-edge technique for mitral regurgitation due to myxomatous degeneration from January 2000 to January 2009 were analyzed retrospectively. Of the 58 patients, 32 patients were male and 26 patients were female, and the age range was from 43 years to 65 years with a mean of (56 ± 6) years, and moderate mitral regurgitation was observed in 18 patients and severe regurgitation in 40 patients, and the prolapse of the anterior leaflet was observed in 50 patients and the prolapse of the bileaflet in 8 patients. The edge-to-edge technique was performed in all patients and the annuloplasty was performed in 44 patients.RESULTS:
There was no perioperative death and serious complication. Postoperative transthoracic echocardiography of all the survivors indicated that the dimensions of left atrial and left ventricular were obviously decreased (P < 0.05) and mitral insufficiency was obviously improved (no regurgitation was observed in 9 patients and trace regurgitation in 30 patients and mild regurgitation in 19 patients) and there was no mitral stenosis. Totally 58 patients were followed up from 24 months to 95 months with a mean of (58 ± 20) months. During the follow-up, there were 2 deaths for noncardiac factors. Freedom from recurrent moderate or severe mitral regurgitation at 5 years after operations was 91.9%. According to undergoing combined annuloplasty or not, 58 patients were divided into the edge-to-edge technique group (14 cases) and the edge-to-edge technique + annuloplasty group (44 cases), and the survival analysis shows there was significant difference on freedom from long-term recurrent moderate or severe mitral regurgitation after operations between two groups (χ(2) = 4.034, P = 0.045) and long-term effect of the latter group was better.CONCLUSIONS:
The edge-to-edge technique can be conveniently used and bring about satisfactory perioperative and long-term effects for mitral regurgitation due to myxomatous degeneration. The combination of the edge-to-edge technique and the annuloplasty can improve the long-term effect significantly.
