RESUMEN
OBJECTIVE: To summarize the experience of mitral vavuloplasty for mitral insufficiency in 53 patients. METHODS: Between January 2001 and September 2006,53 patients (31 males and 22 females) with mitral insufficiency underwent mitral valve repair at our hospital. The mean age was (23.8+/-10.4) years, and the mean weight was (43+/-12) kg,including 29 cases of mitral prolapse,17 congenital mitral insufficiency, 5 rheumatic mitral insufficiency,and 2 other etiology. All operations were performed under cardiopulmonary bypass,moderate hypothermia and under the surveillance of transesophagus echocardiography. RESULTS: There were 2 early postoperative deaths,and another patient failed to repair and received valve replacement afterward. Postoperative echocardiography indicated that mitral insufficiency was completely corrected in 42 patients, and residual mitral regurginitation in the other 8 patients. During the follow-up with mean period 13.8 months,41 patients revealed 28 in NYHA classI,13 in Class II. CONCLUSION: Mitral valve repair should be the preferred modes of surgical correction for regurgitate mitral valves. With proper vavuloplasty technique, patients with selective mitral insufficiency patients may achieve satisfactory effect.

OBJECTIVE: To review the clinical data of pathological morphology, diagnosis, surgical treatment of cor triatriatum in 15 patients. METHODS: Fifteen patients with a mean age of (14.6+/-10.3) years (range from 6 months to 40 years) were performed operations under extracorporeal circulation. Fourteen of the patients had cor triatriatum sinister, and 1 had cor triatriatum dexter; 12 of the 15 patients had other cardiac abnormalities. The excision of the fibromuscular membrane was accomplished through a right atrial incision in all of the 14 cases, and the associated abnormalities were corrected at the same time. RESULTS: One patient died after the operation, and the other survivors had good outcome. CONCLUSION: Operation is necessary if the diagnosis is clear. The patients generally have good prognosis. Surgical results of cor triatriatum depend on the complexity of associated defects and the adequacy of the repair.
