Abstract: Systems and methods for monitoring and evaluating the function of a prosthetic heart valve (PHV) implanted in a patient are discussed. An exemplary medical-device system can receive heart sounds information including vibrational or acoustic information generated by an implanted PHV, and generate an indicator of function of the PHV using a HS metric of received acceleration information. An alert of PHV dysfunction can be presented to a system user. The PHV function may be monitored during a valve replacement procedure to assist in position adjustment of the prosthetic value, or after the valve replacement procedure to assess patient progress in recovery. According to some embodiments, the system can generate a risk indicator indicating patient natural valve function and a need for heart valve repair or replacement.

Abstract: This document discusses, among other things, systems and methods to produce a composite heart sound signal of a patient using a first signal including heart sound information over a first physiologic interval and a second signal including heart sound information over the first physiologic interval.
