摘要 目的探讨经食管超声心动图在心脏瓣膜置换术中的应用效果。方法选取我院86例心脏瓣膜置换术患者为研究对象,所有患者术前均行经胸超声心动图检查,术前、术中及术后行经食管超声心动图检查,以手术病理结果为参考标准,比较术前不同检查方法中主动脉瓣环内径及钙化检出率,手术前后患者瓣膜及主动脉瓣平均跨瓣压差、左心室射血分数及有效瓣口面积指数等心功能指标变化。结果在主动脉瓣环内径测量及钙化检出率方面,经胸超声心动图检查显著低于手术病理结果,二者比较存在统计学差异(P <0.05),经食管超声心动图二维及三维检查显著高于经胸超声心动图检查(P <0.05),且与手术病理结果比较无统计学差异(P> 0.05),术后主动脉瓣平均跨瓣压差较术前显著降低,有效瓣口面积指数及左室射血分数较术前显著升高,前后比较存在统计学差异(P <0.05),所有患者均顺利完成手术,瓣膜功能恢复正常。结论经食管超声心动图可有效提高心脏瓣膜置换术成功率,为手术方式选择提供指导,具有较高的应用价值。
