Unexpected Coronary Sinus Embolization of a Leadless Pacemaker due to Initial Device Failure: A Case Report
Leadless pacemakers reduce complications compared to transvenous systems, but device dislodgement and embolization can occur. We report an 81-year-old man with atrial fibrillation and bradycardia who underwent Micra implantation. Because of inner shaft damage and insufficient tine fixation, the device embolized into the coronary sinus. It was successfully retrieved using a double-snare technique, and a new device was implanted. This case highlights the importance of meticulous deployment technique and thorough intraprocedural assessment of device attachment, as well as troubleshooting strategies for unexpected embolization.
期刊介绍:
Clinical Case Reports is different from other case report journals. Our aim is to directly improve global health and increase clinical understanding using case reports to convey important best practice information. We welcome case reports from all areas of Medicine, Nursing, Dentistry, and Veterinary Science and may include: -Any clinical case or procedure which illustrates an important best practice teaching message -Any clinical case or procedure which illustrates the appropriate use of an important clinical guideline or systematic review. As well as: -The management of novel or very uncommon diseases -A common disease presenting in an uncommon way -An uncommon disease masquerading as something more common -Cases which expand understanding of disease pathogenesis -Cases where the teaching point is based on an error -Cases which allow us to re-think established medical lore -Unreported adverse effects of interventions (drug, procedural, or other).
