“…The process of development of acquired aneurysms is the result of damage to the mitral valve or other conditions leading to an increase in pressure in the left atrium[ 10 ]. At the same time, it is often difficult to differentiate the acquired and congenital forms, as in our case, since moderate changes of the mitral valve can be caused by the presence of the appendage aneurysm itself[ 11 ].…”

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 58-year-old man presented to our hospital complaining of shortness of breath, general weakness, dizziness during physical exertion, and fatigue. Based on the results of echocardiography, an aneurysm of the left atrium was suspected. A free-breathing real-time cine magnetic resonance imaging with electrocardiograph synchronization confirmed the diagnosis of left atrial appendage aneurysm. The patient underwent an aneurysmectomy via 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.

“…In most cases, the disease is detected by chance because of a non-specific clinical picture. A convexity at the contour of the left atrium determined on a chest X-ray requires differential diagnosis with a pericardial cyst and heart and mediastinal tumors[ 10 , 11 ].…”

“…The management of LAA aneurysm is surgical excision even in asymptomatic patients [ 7 ]. The three commonly described aneurysmectomy approaches are midline sternotomy, left thoracotomy and mini-thoracotomy [ 8 , 9 ]. Surgical excision has been advised to prevent the occurrence of AF, systemic emboli, or myocardial dysfunction.…”

Introduction Congenital aneurysm of the left atrial appendage (LAAA) is a very rare heart with potentially serious and life-threatening complications. Diagnosis is difficult because of the asymptomatic forms, until complications arise. Early surgery is the treatment of choice, but the recommendation today remains unclear. Case report We present a case of congenital giant left atrial appendage aneurysm (LAAA), in a 55-year-old, woman, without any medical or surgical history, who presented with dyspnea, in whom transthoracic echocardiograhpy demonstrated the presence of a giant left atrial aneurysm with thickening of the small mitral valve, a chest scan confirmed the diagnosis of LAAA and a myocardial magnetic resonance imaging revealed the presence of thickened mitral valve with bi-valvular balloonization and annular disjunction, thickening of the basal segments of the inferior and lateral wall, left atrial aneurysm with a dilated right coronary artery. Coronary angiography showed a tortuous coronary artery with a loop in the second segment without any significant stenosis. The patient is currently awaiting surgery. Conclusion Left atrial appendage aneurysm is a serious illness will likely require years of medical care and follow up in the absence of surgical treatment. The choice and timing of surgical, conservative or catheter treatment always remains a challenge. Our case report shows that medical treatment is a safe approach that will delay or avoid surgery.

“…Medical management is also reported to delay surgery for avoiding operative risk 17 .Catheter ablation also been reported in a patient with paroxysmal AF and a congenital giant LAA who was successfully treated by percutaneous pulmonary vein antrum isolation (PVAI) 18 .Surgery is focused on excision ofthe sac and Correct any added pathology, like closure of neck repair of mitral valve, antiarrhythmia procedure.…”

Left atrial appendage aneurysm is a rare heart defect; Most often diagnosed incidentally but may be potentially hazardous when presented with a systemic embolization or arrhythmia. So early diagnosis and treatment is indicated. We have successfully operated two cases of left atrial aneurysm in recent past and sharing our experiences through this case reports.
