双孔二尖瓣技术治疗二尖瓣关闭不全

Double orifice technique to correct mitral insufficiency

目的使用双孔二尖瓣技术治疗不同原因所致的二尖瓣关闭不全,探讨该技术的有效性、合理性和最佳指证。方法以二尖瓣前叶脱垂为主要病变的二尖瓣关闭不全病人22例,将其二尖瓣前叶脱垂部位边缘与相对应的后瓣边缘缝合形成双孔二尖瓣,利用超声心动图等指标评价手术效果。结果全组术前平均瓣口面积为(8.4±1.4)cm2术后为(4.2±1.6)cm2,17例未探及反流,3例轻度反流,2例为中度反流,二尖瓣狭窄及死亡。结论双孔二尖瓣技术是矫治二尖瓣关闭不全的一种简便而有效的方法。

Objectives To evaluate the feasibility and effectiveness of double orifice technique for mitral insufficiency caused by different etiology.Methods Twenty-two cases with mitral insufficiency and the prolapse of anterior leaflet was main malformation,underwent mitral valve repair using the Double-orifice technique i.e.the edge of prolapsing anterior leaflet was anchored to the corresponding free edge of posterior leaflet.And the clinical effect was evaluated by echocardiography and other clinical index.Results The mean postoperative valve area was(4.2±1.6) cm2 against the preoperative valve area of(7.8±1.4) cm2;Mild regurgitation was found in 2 patients and moderate regurgitation was found in 3 patients after operation.There were no stenosis of valve and no late death.Conclusions Double orifice technique is a simplified and effective method to correct mitral insufficiency.
