We performed aortic valve replacement in 24 patients aged over 70 with small calcified valves. The surgical management of such patients remains controversial as the extensive calcification compromises implantation. Hence, we used an ultrasonic debridement instrument to remove calcium and selected a small prosthesis with the largest possible orifice without enlargement of the aortic annulus. Echocardiography showed significant reductions in left ventricular mass index compared with preoperative values. Early and mid-term prognosis has been relatively good.
我们对24例年龄超过70岁、伴有小钙化瓣膜的患者进行了主动脉瓣置换术。此类患者的手术管理仍存在争议，因为广泛的钙化会影响瓣膜植入。因此，我们使用超声清创器械去除钙化，并选择了一种尽可能大孔口的小型人工瓣膜，而不扩大主动脉瓣环。超声心动图显示，与术前值相比，左心室质量指数显著降低。早期和中期预后相对良好。
