    Abstract: A holder for a hybrid heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The hybrid heart valve includes a non-expandable, non-compressible prosthetic valve and a self-expandable anchoring stent, thereby enabling attachment to the annulus without sutures. A first suture connects the holder to the valve and constricts an inflow end of the anchoring stent. A second suture connects the holder to the valve and extends down three holder legs to loop through fabric on the valve. Both sutures may loop over a single cutting well on the holder so that severing the first and second sutures at the single cutting well simultaneously releases the tension in the first suture, permitting the inflow end of the anchoring stent to expand, and disconnects the valve holder from the prosthetic heart valve.

    Abstract: A prosthetic heart valve configured to replace a native heart valve and for post-implant expansion and having a valve-type indicator thereon visible from outside the body post-implant. The indicator communicates information about the valve, such as the size or orifice diameter of the valve, and/or that the valve has the capacity for post-implant expansion. The indicator can be an alphanumeric symbol or other symbol or combination of symbols that represent information about the characteristics of the valve such as the valve size. The capacity for post-implant expansion facilitates a valve-in-valve procedure, where the valve-type indicator conveys information to the surgeon about whether the implanted valve is suitable for the procedure and informs the choice of the secondary valve.

    Abstract translation: 一种假体心脏瓣膜，其构造成代替天然心脏瓣膜并用于植入后扩张，并且在体外植入后可从外部观察到瓣膜型指示器。 指示器传达关于阀的信息，例如阀的尺寸或孔直径，和/或阀具有用于植入物扩张的能力。 指示符可以是代表关于阀的特性的信息的字母数字符号或其他符号或符号的组合，例如阀的尺寸。 植入后扩张的能力有利于瓣膜瓣膜手术，其中瓣膜型指示器向外科医生传达关于植入的瓣膜是否适于手术并且通知二次瓣膜的选择的信息。
