Transcatheter treatment of patients with degenerated aortic valve stentless prosthesis and low proximal coronary ostia to the aortic annulus remain a challenge because of the elevated risk for coronary obstruction. Newer generation transcatheter aortic valve devices that engage and pull the aortic valve calcium towards the aortic annulus may be beneficial in these patients. We present a case of successful treatment of a degenerated tubular stentless prosthesis with low coronary ostia with a Symetis Acurate TA prosthesis.
对于退化性无支架主动脉瓣膜假体且冠状动脉开口近端至主动脉瓣环距离较短的患者，经导管治疗仍然是一项挑战，因为冠状动脉阻塞风险较高。新一代经导管主动脉瓣装置可将主动脉瓣钙化组织向主动脉瓣环牵拉，这可能对这类患者有益。我们报告一例使用Symetis Acurate TA假体成功治疗退化性管状无支架假体且冠状动脉开口较低的病例。
