Sensors for prosthetic heart devices

A prosthetic heart valve system comprising:

• a prosthetic heart valve including:
• a stent extending along a longitudinal axis from an outflow portion to an inflow portion and having an expanded condition and a collapsed condition;
• and
• a valve assembly mounted to the stent;
• and
• a first sensor configured to measure physiological data, the first sensor including a body extending along a body axis and a plurality of apertures extending through the body on opposite sides of the body axis,
• wherein a first suture attaches the first sensor to the stent via at least some of the plurality of apertures so that, in the expanded condition of the stent, the longitudinal axis of the stent is not parallel to the body axis of the first sensor, and in the collapsed condition of the stent, the longitudinal axis of the stent is parallel to the body axis of the first sensor.
