Embolization Followed by Self-Repositioning of a CardioMEMS™ Wireless Pulmonary Artery Hemodynamic Monitoring Sensor Device.

We report a case of early migration of a CardioMEMS™ heart failure device (Abbott) from the right to the left pulmonary artery, which then spontaneously repositioned itself within the left pulmonary artery without the need for intervention. A balloon Swan-Ganz catheter was then used to reposition the device, successfully lodging it into a more distal position. This case underscores the importance of close device monitoring and demonstrates an effective technique for repositioning without device retrieval.
