Why the study?
Left atrial appendage aneurysm is a rare but potentially hazardous defect with growing risk of lethal complications as it enlarges, with only about 150 cases described in the literature.
Left atrial appendage aneurysm is a rare pathology that may require complex surgical and interventional management, including annuloplasty and stenting, to prevent complications.
Successful recovery after complex repair may support intervention in symptomatic cases; leaves open optimal strategies for this rare entity.
BACKGROUND: An aneurysm of the left atrial appendage is one of the rare but potentially hazardous heart defects. The risk of lethal complications grows with its size. To date, about 150 cases of this defect have been described in the literature. We present a case of left atrial appendage aneurysm with the deformation of the mitral valve and the left main coronary and circumflex artery, which required mitral valve annuloplasty and bifurcation stenting. CASE SUMMARY: a median sternotomy with cardiopulmonary bypass. Intraoperative transesophageal echocardiography revealed relative mitral insufficiency that was corrected with an annuloplasty ring. Intraoperative coronary angiogram showed impaired blood flow in the left main coronary and circumflex artery and 60% stenosis. For this reason, bifurcation stenting was performed. The patient had an uneventful postoperative clinical course and was discharged from the hospital on the 10th day in a satisfactory condition. CONCLUSION: Left atrial appendage aneurysm is a rare and dangerous heart pathology that requires surgery to prevent related complications.
