1. An apparatus comprising:

  • an implantable sensor configured for coupling to an implantable lead, wherein the implantable lead is configured for placement through a heart valve, and wherein the implantable sensor provides an electrical vibration sensor signal representative of mechanical vibration induced on the implantable lead by the heart valve impacting the implantable lead;

    a signal analyzer circuit communicatively coupled to the implantable sensor, wherein the signal analyzer circuit is configured to;

    determine a baseline of the vibration sensor signal induced by the heart valve;

    detect a change in the vibration sensor signal from the baseline vibration sensor signal; and

    provide an indication of the change to a user or process.
