经股动脉经导管主动脉瓣置换术治疗单纯主动脉瓣反流的研究进展

经导管主动脉瓣置换术（TAVR）已成为国内外指南推荐治疗老年主动脉瓣狭窄（AS）的一线治疗方案,也适用于AS合并不同严重程度主动脉瓣反流的患者,但在单纯主动脉瓣反流（PAR）中却不做常规推荐,传统外科主动脉瓣置换术仍然是治疗PAR的金标准。外科手术禁忌或高危PAR患者,常放弃外科手术治疗,选择保守治疗,而后者的死亡率更高。经股动脉TAVR(TF-TAVR)为其提供了一种替代治疗方案,尽管仍面临手术技术要求高、缺乏针对PAR的瓣膜系统和术后长期随访数据等挑战,但随着TAVR技术经验积累、新一代瓣膜系统的发展及长期随访数据的反馈,TF-TAVR治疗PAR逐渐被证实是一种安全、可行的外科手术替代治疗方式,本文对TF-TAVR治疗PAR实施要点、临床研究现状以及未来的发展进行综述。     

经导管主动脉瓣置换术治疗白塞病合并重度主动脉瓣反流一例

Urgent transcatheter aortic valve replacement for severe acute aortic regurgitation following open mitral valve surgery

Transcatheter aortic valve replacement (TAVR) is not currently approved for pure native valve aortic incompetence, and is typically performed on a compassionate basis in selected patients who are at high risk for conventional surgery. We describe the first use of TAVR to treat iatrogenic severe acute pure aortic incompetence following mitral valve surgery. A 71‐year‐old gentleman developed life‐threatening acute aortic regurgitation (AR) within hours of a very challenging fifth open heart mitral valve replacement. Careful inspection of echocardiographic and computed tomographic imaging identified the cause as a disrupted left coronary cusp at the commissure caused by the surgical mitral annular reconstruction. Medical management with afterload reduction failed with recurrent pulmonary edema, and a sixth open heart surgery was deemed prohibitively high risk. The lack of aortic annular calcium onto which anchors a transcatheter valve was a concern for TAVR. However, we postulated that the struts of the mitral valve bioprosthesis would offer some support to the TAVR valve. We opted for a self‐expanding system because of concerns about potential unfavorable interaction between the balloon onto which balloon‐expandable bioprosthesis is mounted and the struts of the mitral bioprosthesis, and because the Evolut R system has additional anchoring points at the crown which might enhance transcatheter valve stability in the non‐calcified annulus, compared with the Edwards Sapien system. Transfemoral TAVR, performed with a Medtronic Evolut R 34 mm system under general anesthesia and using moderately rapid ventricular pacing, was successful with minimal residual AR. On follow‐up 1 month later the patient was asymptomatic, and the aortic and mitral bioprostheses were functioning normally on echocardiogram.     

Long-term outlook for transcatheter aortic valve replacement

Transcatheter aortic valve replacement (TAVR) revolutionized the treatment of severe symptomatic aortic stenosis (AS). TAVR is increasingly offered for lower-risk patients. The role and place of TAVR in the future treatment of AS is not clear yet. In this review, we discuss the long-term outlook for TAVR, its challenges and its relationship to conventional surgical aortic valve replacement.     

Transseptal approach for the management of paravalvular regurgitation after transcatheter aortic valve replacement

In the era of transcatheter aortic valve therapies, the presence of residual paravalvular regurgitation (PVR) after transcatheter aortic valve replacement (TAVR) may become a clinical challenge. Management of late symptomatic PVR is still unknown. We describe a challenging case of percutaneous closure attempt of a clinically significant PVR in a patient after Edwards SAPIEN (Edwards Lifesciences, CA) TAVR. © 2012 Wiley Periodicals, Inc.
