Key result
A left atrial clipping device caused delayed severe coronary artery stenosis resulting in ventricular fibrillation 2 months after cardiac surgery, necessitating clip removal.
Why the study?
A clipping device can impinge on the coronary artery after left atrial appendage occlusion during cardiac surgery, causing rare perioperative or delayed cardiac ischaemia.
Case Report (n=1)
Left atrial clipping devices can cause delayed coronary artery stenosis and life-threatening arrhythmias, highlighting the need for awareness of this rare complication even months after surgery.
Rare delayed coronary stenosis after LAA clipping may cause late VF; leaves open questions on incidence and surveillance needs.
A clipping device may impinge on the coronary artery following left atrial appendage occlusion during cardiac surgery, causing rare cardiac ischaemia perioperatively. This report highlights a case of delayed severe coronary artery stenosis resulting in ventricular fibrillation 2 months after cardiac surgery with the implantation of a left atrial clipping device. Following a percutaneous coronary intervention, the patient underwent clip removal surgery. Postoperative three-dimensional heart model verification revealed that the base of the left atrial appendage was more dorsal than usual, thereby increasing the potential risk of the clip impinging on the coronary artery. We should remember that this rare complication can occur after left atrial clipping, either in the early postoperative period or later.
