Abstract
A method is described for use with a heart of a subject, the heart having a valve and an atrium upstream of the valve. The method includes transluminally advancing multiple tissue anchors to the atrium; and securing an elongate contraction member at least partly around an annulus of the valve by anchoring the tissue anchors to the annulus, such that the tissue anchors are distributed along the elongate contraction member. The method further includes subsequently contracting the annulus by applying tension the elongate contraction member, such that a radiopaque indicator that is disposed within the heart and that is coupled to the contraction member undergoes a conformational change in response to the tension. The conformational change of the radiopaque indicator within the heart is observed, and the tension is adjusted responsively to the observed conformational change. Other embodiments are also described.
