The CardioClip study is exploring the use of a wireless sensor to monitor pressure in the pulmonary artery. This sensor is inserted much like the mTEER procedure, a non-surgical method through a vein in the groin. The investigators want to find out if the sensor, by constantly sending information about heart function, can help improve patient outcomes. This means doctors could adjust medications based on real-time pressure changes detected by the sensor. The results from this study will help pave the way for future trials, asking if using these wireless sensors could benefit people with valve disease and heart failure.
