Abstract
Apparatus is provided for use at a native valve of a heart of a subject. The apparatus includes a delivery tube, transluminally advanceable to the heart; and a prosthetic valve support, configured to support a prosthetic valve at the native valve, and comprising an upstream support portion. The upstream support portion has a working configuration in which it is generally annular and has (1) a tissue-contacting side configured to be placed against an atrial surface of the native valve, and (2) an opposing side, and defines an opening therebetween. The upstream support portion also has a delivery configuration in which the upstream support portion is rolled up to define a channel, and is disposed within the delivery tube. The upstream support portion is configured to be transitioned from the delivery configuration to the working configuration by being exposed from the delivery tube, and unrolled.
