Intermittently stuck valve after mitral valve replacement diagnosis by echocardiography: a case report
-
摘要: 本例患者二尖瓣机械瓣置换术后6年出现间歇性心悸, 术前经胸超声心动图(TTE)提示二尖瓣机械瓣卡瓣, 拟行瓣膜再次置换手术。术前麻醉后TTE实时三维经食管超声心动图(3D-TEE)提示存在不稳定性卡瓣, 原因为瓣环周围血管翳形成过长, 故更换手术方式, 未对二尖瓣机械瓣进行再次置换, 仅清除机械瓣周围血管翳。术后随访6个月, 患者心功能状态恢复良好, 生活质量明显改善。Abstract: The patient had the symptom as intermittent palpitations after the surgery of mechanical mitral valve replacement for six years later.Transthoracic echocardiography (TTE) indicated that mechanical mitral valve was stuck.Second valve replacement surgery was planned for treating with mitral valve.Preoperative anesthetized TTE and real-time three-dimensional transesophageal echocardiography (3D-TEE) indicated the presence of an unstable stuck valve, with the instability caused by excessive pannus formation around the annulus.Finally, we choosed to clean the surrounding pannus rather than replace the mechanical mitral valve again.Follow up in 6 months, the cardiac function recovered well, and the quality of life improved significantly.
