Unmonitored changes in LA pressure of patients on the TandemHeart™ PTVA System (below a certain pressure threshold) may pose a threat to the patient due to a potential “suck down” of tissue (overdrainage of LA). This causes tissue damage and reduced blood flow.
Real time pressure readings in the LA can possibly prevent the tissue “suck down”.
The ultimate goal is to enable real-time measurements of Left Atrial Pressure (LAP) with TandemHeart use, by placing an absolute pressure sensor chip at the tip of the cannula.
+ Study the feasibility of the incorporation of RF transmitter complex to transmit the real-time measurements without need for wiring.
