Key result
Transesophageal echocardiography-guided left atrial appendage occlusion without fluoroscopy was successfully performed in 100% of 14 patients with atrial fibrillation, with no serious complications.
Why the study?
The authors sought to investigate a new method of left atrial appendage occlusion without fluoroscopy.
Does left atrial appendage occlusion guided only by transesophageal echocardiography provide safe and successful procedural outcomes in patients with atrial fibrillation?
Does left atrial appendage occlusion guided only by transesophageal echocardiography provide safe and successful procedural outcomes in patients with atrial fibrillation?
Left atrial appendage occlusion guided solely by transesophageal echocardiography is a feasible and safe approach that eliminates radiation exposure.
May enable fluoroscopy-free LAAO in select AF patients; leaves open confirmation in randomized trials.
AIMS: To investigate a new method of left atrial appendage occlusion without fluoroscopy. METHODS AND RESULTS: We performed left atrial appendage occlusion for 14 patients with atrial fibrillation in our hospital. All of the surgeries were completed in a general surgery setting, avoiding fluoroscopy, and in each case, the entire procedure was guided by transesophageal echocardiography (TEE). All of the surgeries were performed through the femoral vein pathway. All operations went smoothly with no serious complications. Postoperative TEE indicated that each device was in a good position, and there was no residual shunt around any of the devices. CONCLUSIONS: TEE-guided left atrial appendage occlusion is safe and reliable, simplifies the procedure, protects doctors and patients from radiation, and is gradually becoming the mainstream operation for left atrial appendage occlusion. This trial is registered with ChiCTR1800018387.
