Abstract:
ObjectiveTo review and summarize the experiences of the modified mitral valve annuloplasty for mitral valve regurgitation (MR) in children.MethodsOne hundred and six patients with moderate to severe MR were retrospectively studied from March 1999 to December 2009.They aged from 0.4 to 8.5 years [ mean (3.7 ± 1.8) years ]and weighted from 6.6 to 52.0 kg [ mean(10.0 ± 3.5) kg].There were 69 males and 37 females.The heart function was evaluated by echocardiography.Patients were divided into three groups according to the age: group 1, ＜6 months , 16 cases; group 2, from 6months to 2 years, 51 cases; and group 3, from 2 years to 8.5 years, 39 cases.Seven cases were MR combined with mitral valve stenosis. Different operations were performed according to preoperative homodynamic, heart function and anatomical structure.ResultsThe operative mortality rate was 2.8％.In 3 died patients, 2 were due to MR and 1 due to severe pulmonary hypertension.104 cases were recovered.All patients were followed up 3 months to 3 years.ConclusionModified mitral valve reconstruction is necessary for children with moderate to severe MR.It should be the first choice for MR patients associated with other cardiac malfomation.This technique could prolong the time for mitral valve replacement when needed.Moreover,this technique not only reduces the valve injury but also decreases the reoperation rate.
