经导管主动脉瓣"瓣中瓣"植入1例
Chinese Journal of Evidence-Bases Cardiovascular Medicine(2021)
Abstract
主动脉瓣狭窄(AS),尤其是重度AS,既往主要依靠外科换瓣手术,而传统开胸术创面大,术后恢复慢,对于身体条件及心功能较差的老年患者而言风险高,甚至直接失去手术机会.近年来介入导管技术不断发展,经导管主动脉瓣植入术(TAVI)逐渐得到推广.本文报道1例重度AS患者症状反复发作,内科加强抗心力衰竭(心衰)治疗效果不佳,最终接受手术治疗,患者一般情况差、病情重,手术风险高,最终决定行TAVI,以主动脉瓣"瓣中瓣"解决了重度AS问题.
