“…In addition, the blood flow in the aneurysm is often slow, making thrombus formation easier. Once the thrombus dislodges, it will lead to a series of embolism symptoms [1,7,8]. In our case, the patient did not show any special symptoms, and the LAAA was accidentally discovered during a routine medical evaluation.…”

“…The incision approaches include median thoracotomy, right chest mini-incision and total thoracoscopy. At present, the most common treatment choice is aneurysm resection under cardiopulmonary bypass through a median sternotomy approach, and pericardial reconstruction is feasible if necessary [8]. In our case, the patient did not show any accompanying symptoms; therefore, he had no need for targeted drug treatment before and after the operation.…”

Background Left atrial appendage aneurysm is a rare cardiac mass, with only a few cases reported. There are usually no specific symptoms, and a few patients visit the doctor with symptoms. Case presentation A 20-year-old male presented to our hospital with a “pericardial cyst found by medical evaluation in another hospital for 2 years.” Cardiac ultrasound performed at clinics of our hospital suggested a cystic dark area in the left ventricular lateral wall and the anterior lateral wall, consistent with a pericardial cyst and mild mitral regurgitation. After further relevant examinations and ruling out contraindications, an excision of the left atrial appendage aneurysm was performed under general anesthesia and cardiopulmonary bypass with beating—heart. The postoperative pathological results identified that: (left atrial appendage) fibrocystic wall-like tissue with a focal lining of the flat epithelium, consistent with a benign cyst. Conclusion Left atrial appendage aneurysms are rare and insidious. They are usually found by chance during medical evaluations. If the location is not good or the volume is too large, then compression symptoms or arrhythmia, thrombosis and other concomitant symptoms will occur. Surgical resection is presently the only effective radical cure for a left atrial appendage aneurysm.

“…Isolated appendage aneurysms in healthy young adults have been resected endoscopically with access through an anterolateral mini-thoracotomy while on cardiopulmonary bypass using the femoral artery and vein. 15,16 Given the known risk and profound consequences of thromboembolic events, all patients should be considered for surgical resection regardless of aneurysm size or symptoms. Patients who are unable or decline to undergo surgical resection are naturally at higher risk for thromboembolic events, arrhythmias, and other morbidities.…”

Background Left (LAAA) and right atrial appendage aneurysms (RAAA) are rare entities, and their natural history, management, and long-term outcomes are not well studied. Methods This retrospective review includes all patients from 2000 to 2021 with atrial appendage aneurysms at our institution identified using an electronic search tool. LAAA and RAAA were confirmed using multimodality imaging and intraoperative findings. Results We identified 13 (87%) patients with LAAA and 2 (13%) with RAAA. At diagnosis, 11 (73%) were female, mean age was 51.4 ± 18.8 years, and ejection fraction 56.5 ± 13.1%. Three (20%) patients had congenital heart disease including 2 (13%) with atrioventricular septal defects and 1 (7%) with congenitally corrected transposition. LAAA/RAAA was diagnosed due to new-onset atrial fibrillation (AF) in 6 (40%) patients and embolic stroke in 2 (13%). Ten patients had preexisting AF diagnosed 2.9 ± 1.4 years earlier at a mean age of 50.2 ± 15.5 years. Thrombus within the aneurysm was identified in 2 (15%) LAAA patients. All patients were on anticoagulation and follow-up of the cohort from diagnosis was 7.1 ± 6.2 years. Eleven (73%) patients were surgically managed with 7 (64%) lesions excised, 1 (9%) stapled, and 3 (27%) ligated. Postoperative complications occurred in 2 (18%) patients with 1 (7%) developing tricuspid regurgitation and another with pericardial effusion and tamponade. Conclusions Atrial appendage aneurysm is a rare disease and nearly half of patients present with AF. Surgical treatment with concomitant AF ablation is a reasonable and safe management option.
