经导管主动脉瓣置换术治疗二叶式主动脉瓣狭窄研究进展

Transcatheter Aortic Valve Implantation in Treating Bicuspid Aortic Valve Stenosis

二叶式主动脉瓣是常见的先天性心脏瓣膜畸形,常伴发主动脉瓣狭窄,老年患者通常需主动脉瓣置换术,但手术风险极高。经导管主动脉瓣植入术是治疗有症状的严重主动脉瓣狭窄一种有效的治疗手段。二叶式主动脉瓣由于解剖结构复杂,行经导管主动脉瓣植入术风险高,术后并发症多,在早期被作为经导管主动脉瓣植入术的禁忌证,但随着科技的发展以及经验的积累,经导管主动脉瓣植入术治疗二叶式主动脉瓣患者的有效性以及安全性得到显著提高,现将近期经导管主动脉瓣植入术治疗二叶式主动脉瓣的进展进行介绍。

Bicuspid aortic valve is the most frequently occurring congenital heart defect and often associated with aortic valve stenosis.However,aortic valve replacement is usually required in elderly patients,but the risk of surgery is often very high.Transcatheter aortic valve implantation is an effective treatment for severe symptomatic aortic stenosis.In the early times,bicuspid aortic valve has been considered a relative contraindication because of the complex anatomical structure,high risk,and many postoperative complications.Nevertheless,with the development of technology and the accumulation of experience,the efficacy and safety of transcatheter aortic valve implantation in patients with bicuspid aortic valve were significantly improved.This article describes the progress of transcatheter aortic valve implantation in treating bicuspid aortic valve.
