Abstract:

Objective To compare the effects of chordal transfer, edge-to-edge suture and artificial chordae techniques in treatment of mitral insufficiency induced by anterior mitral valve diseases. Methods According to different surgical methods, 171 patients with anterior mitral valve diseases were divided into chordal transfer group (group Ⅰ), edge-to-edge suture group (group Ⅱ) and artificial chordate group (group Ⅲ), with 57 patients in each group. The mitral valve close was examined by transesophageal echocardiography (TEE), the effective mitral valve areas and parameters related to left ventricular function were measured by transthoracic echo, and the short and middle term data of mitral valve close were followed up. Results The percentages of patients with satisfied mitral valve revealed by postoperative TEE in group Ⅰ, group Ⅱ and group Ⅲ were 82.46% (47/57), 85.96% (49/57) and 84.21% (48/57), respectively. The postoperative effective mitral valve areas of all three groups were significantly smaller than those before operation (P<0.05). The postoperative left ventricular end diastolic diameters in all three groups were significantly shorter than those before operation (P<0.05). After follow up for 1 to 11 years (3.28 years in average), the percentages of satisfied mitral valve close in group Ⅰ, group Ⅱ and group Ⅲ were 82.46% (47/57), 85.96% (49/57) and 82.46% (47/57), respectively. Conclusion Chordal transfer, edge-to-edge suture and artificial chordae techniques are effective in treatment of anterior mitral valve diseases, and the choice of surgical procedure should be based on the age and disease condition.
