Abstract

Intraprocedural device dislodgement of a 24-mm Watchman™ left atrial appendage (LAA) closure device occurred in a 83-year-old female with a wide left atrial appendage ostium (broccoli configuration) and a surgical mitral valve reconstruction. Device rested in the atrial cavity. A second stable 12French transseptal electrophysiological sheath and two snares were needed to stabilize, elongate and gently guide the device into the second sheath. One of the snares was unclamped at its proximal end and retrogradely pulled through. After successful retrieval, a 27-mm Watchman™ device could easily be implanted in the very same session via the left delivery sheath. Patient was discharged from hospital in good general health after regular turnaround time.
