对于无症状的严重的主动脉瓣狭窄 (AS)患者,目前的指南建议,观察随访直到症状出现才行主动脉瓣置换术 (AVR) 。

研究者对无症状的严重AS患者进行了一项研究,探究一经诊断就行AVR治疗和保守策略两种方案对患者的长期影响。

该研究在2003年1月-2011年12月间,从多中心注册库纳入了3815名严重AS患者(主峰喷射速度>4.0 m/s,或平均主动脉压力梯度>40 mmHg,或主动脉瓣口面积<1.0 cm2)。对1808名无症状的患者,有291名进行了AVR手术治疗,1517名进行保守治疗。平均随访时间是1361天,第2年随访率为90%。 研究者根据倾向评分匹配了一个包含582名患者的队列,AVR和保守治疗组各291人,通过该队列进行主要的分析。

该队列除了AVR组年轻一点、主动脉瓣狭窄程度严重一点,其他基线资料两组相似。在保守治疗组,随访期间有41%的患者行了AVR。对于全因死亡的5年发生率以及因心衰住院的发生率在AVR组显著低于保守治疗组(15.4% vs 26.4%, p=0.009, and 3.8% vs 19.9%, p<0.001)。

研究结果表明,对于无症状的严重AS患者,当前推荐的保守治疗策略对该类患者的长期预后并不理想,若是诊断后便进行AVR手术治疗,可能会改善其长期预后。

CHC 2014:亚洲主动脉瓣狭窄患者情况更复杂

“由于种族差异,亚洲主动脉瓣狭窄患者主动脉环更为纤小且情况更为复杂,因此在进行经导管主动脉瓣置换术(TAVI)术要更为谨慎。另外,‘三个臭皮匠顶个诸葛亮’,成功的TAVI术离不开每一位参与其中的心脏团队的成员,而适宜的培训加上每位成员的努力,就会最大程度使手术完善、患者受益。”来自日本东京帝京大学医学部的Yusuke Watanabe 教授在中国心脏大会(CHC2014)介绍心脏团队建设时如是
