  • Changes of left ventricular structure and function after minimally invasive repair of mitral valve prolapse

    ObjectiveTo evaluate the changes of left ventricular structure and function by echocardiography and its grading of left ventricular diastolic function in patients with mitral valve prolapse treated by minimally invasive mitral valve repair.MethodsBy retrospective analysis, 37 patients including 25 males and 12 females aged 53.49±11.02 years with mitral valve prolapse who underwent minimally invasive mitral valve repair were as an operation group, and 34 healthy persons including 19 males and 15 females aged 54.26±8.33 years matched by age and sex were selected as a control group. Ultrasound parameters of every participant were routinely collected before operation, 1 month, 3 months, 6 months and 1 year after operation, and left ventricular diastolic function was graded. The ultrasound parameters between the two groups were compared.ResultsThe diameters of left ventricular end systolic and diastolic phase, left atrial diameter and left ventricular volume in the operation group were significantly smaller than those before operation. The diameters of left ventricle and left atrium after operation were significantly shorter than those before operation, but they were still larger than those of the control group. The ejection fraction value decreased significantly at one month after the operation and then returned to normal level. The incidence of left ventricular diastolic dysfunction at 6 months and 1 year after operation was significantly lower than that before operation (P<0.05).ConclusionMinimally invasive repair for patients with mitral valve prolapse can significantly improve systolic and diastolic functions of left ventricle while reconstructing left atrial and left ventricular structures.
