华中地区首例!免缝合主动脉瓣置换术在郑州成功实施

免缝合主动脉瓣置换术为心脏外科专家和患者提供了一个全新的先进解决方案。

3月17日,阜外华中心血管病医院副院长、全国知名心外科专家程兆云教授带领团队,成功实施华中地区首例免缝合主动脉瓣置换术,为患者解决了主动脉瓣膜疾病难题。

免缝合主动脉瓣置换术为心脏外科专家和患者提供了一个全新的先进解决方案。该手术的成功实施,标志着华中地区主动脉瓣外科置换术正式开启免缝合术式新时代。

接受这项领先技术治疗的患者姓李,来自商丘民权县,已经有68岁高龄。

5年前,李先生出现间断性心慌等症状,经治疗后症状减轻。1个月前,李先生感冒后,心慌症状加重,在民权县某医院住院治疗,被诊断为心律失常、心房颤动。

经过一段时间的治疗,心慌症状没有明显改善。

为寻求进一步治疗,家人带李先生来到阜外华中心血管病医院。

进一步完善检查后,心内科接诊的付海霞教授等专家发现,引起患者心慌的罪魁祸首除了心房纤颤外,还有心脏主动脉瓣狭窄和关闭不全。

李先生心脏的主动脉瓣狭窄和关闭不全到了什么程度了呢?

已经导致心室增大、心脏收缩及舒张功能降低。

鉴于患者病情复杂,经过心外科程兆云、赵子牛教授等会诊研究,患者需要进行瓣膜置换手术,结合患者的病情,专家们决定采用先进的免缝合主动脉瓣置换术,为患者破解难题。

为确保手术顺利进行,3月17日早上7:30,程兆云教授召集心外科、麻醉科、超声科、体外循环、手术室、重症监护等等多学科专家,对李先生的病情进行术前讨论,制定详细手术方案。

与此同时,专家们还通过互联网,与加拿大阿尔伯塔大学医学院汪少华教授共同分析患者病情,探讨免缝合主动脉瓣置换术的技术要领。

病人进入手术室后,麻醉科副主任赵亮教授实施麻醉和监护。手术开始后,程兆云、赵子牛教授等精准操作,体外循环科杨雷一、李建朝等专家实施体外循环管理。

专家们先为患者施行了房颤射频消融术,解决其心律失常问题。然后打开主动脉,切除患者病变的主动脉瓣膜,通过专用输送系统,准确地把人工瓣膜输送到预定位置。

由于该技术置入主动脉瓣膜无需缝合,手术操作简便,总体外循环时间仅1个小时余。术后经食道超声心动图结果显示,新置换的主动脉瓣启闭功能良好,无瓣周漏,心脏跳动有力,心电图显示为正常的窦性节律,术前的房颤彻底消失,而且没有心肌缺血的现象,手术获得成功。

程兆云教授介绍,免缝合主动脉瓣膜置换术具有切口小、植入快、安全性高、并发症发生率低、远期效果确切等优点。与传统外科瓣膜置换相比,免缝合瓣膜置换术不需要外科专家在主动脉瓣附近的局限空间内,进行复杂的缝合打结等操作,能够有效减少体外循环和心肌缺血时间,降低手术后心、脑、肝、肾等重要器官并发症发生率。

心脏瓣膜病是一种常见的心脏疾病,其患病率随年龄增长而显著增高。心脏瓣膜病致死率较高,在人口老龄化背景下,心脏瓣膜病死亡人数不断增长。免缝合主动脉瓣置换术将为更多高龄、重症瓣膜病患者带来重获健康的机会。
