ABSTRACT
Objective To evaluate the effect of edge-to-edge technique of anterior mitral valve prolapse using transthoraeic echocardiography(TTE). Methods Nineteen patients with anterior mitral valve prolapse underwent randomized operation using edge-to-edge technique. The grade of mitral regurgitation(MR),mitral valve are (MVA), the diameter of left atrial(LAD) and left ventricle(LVD), left ventricular ejection fracion(LVEF) and pulmonary artery systolic pressure(PASP) were evaluated. Results All the patients with anterior mitral valve prolapse had severe MR before the operation whereas the degree of MR changed into absence to mild degree after the procedure. There were significant statistic differences between pre- and post edge-to-edge procedure:LAD(51.63±10.03)mm vs (44.79±9.22)mm, P = 0.000, LVD(59.37±8.29)mm vs (52.68±7.31)mm, P = 0.000 ; PASP (45.37±18.34)mm Hg vs (33.00± 9.43)mm Hg, P = 0.002,1 mm Hg = 0.133 kPa;MVA(4.13±0.24)cm<'2> vs (2.90±0.28)cm<'2>, P = 0.000,while LVEF changed little[(66.0±9.0)% vs (67.0±6.0) %, p = 0.751]. Conclusions The edge-to-edge technique is a simple and effective surgical method which can remain subvalve structure,restore the normal morphology of left atria,left ventricle and maintain the function of left ventricle.
