AbstractA heart valve prosthesis containing electronic circuitry for monitoring valve performance provides information to an implanted transceiver arranged to transmit digital or analog data transcutaneously to an external transceiver. The implanted electronics may be integrally contained within the heart valve prosthesis, or alternatively, may be separately housed in a moisture-proof container within the patient's body but external to the heart. By coupling the implanted transceiver to a pulse generator and electrode combination, electrical stimulating pulses can be applied to the heart upon command from an externally located monitor/transceiver combination.
