“…Despite the large size of the aneurysm, our patient did not have any of the following symptoms associated with compression of surrounding structures: (1) Compression of the left ventricle by the aneurysm may cause an increase in filling pressure and diastolic dysfunction, leading to the appearance of shortness of breath and heart failure[ 13 , 14 ]; (2) Compression of the left anterior descending artery may manifest as angina pectoris[ 15 ]; (3) A characteristic sign of irritation of the left phrenic nerve is hiccups[ 6 ]; and (4) The aneurysm proximity to the respiratory tract may cause a dry, unproductive cough[ 16 ].…”

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.

“…Some symptoms of this disease may not be related to the heart, so that the diagnosis is challenging in such cases. The most common manifestations are heart palpitations (43%), shortness of breath (22%), heart rhythm disturbances (15%), embolic disorders of cerebral circulation (11%), and chest pain, and discomfort (7%) ( 8 , 22 ). Cough and hiccups have been described as very rare and atypical presentations ( 7 , 8 ).…”

BackgroundCongenital left atrial appendage aneurysm (LAAA) is a rare cardiac anomaly with a variety of presentations, from being asymptomatic to potentially serious complications such as systemic thromboembolism and atrial tachyarrhythmia.Case PresentationWe report a case of congenital giant LAAA in a 35-year-old man presenting with acute massive cerebral infarction and atrial fibrillation (AF) with rapid ventricular rate. The AF was refractory to conventional antiarrhythmic agents, such as amiodarone and electrical cardioversion, but restored and maintained sinus rhythm after surgical resection of LAAA. The patient remained free of events and was in sinus rhythm during half-year follow-up.ConclusionGiant LAAA has the potential causing serious complications and should be managed surgically in most cases.
