Huge left atrial appendage aneurysm revealed by chronic hiccups

Abstract

Left atrial appendage (LAA) aneurysm is an extremely rare anomaly. So far, less than one hundred cases only have been reported worldwide. Revelation modes are dominated by complications such as arrhythmias and thromboembolic events. We herein report a pediatric case of huge congenital LAA aneurysm with an original revelation mode that has never been described before in medical literature.

Left atrial appendage aneurysm: A case report

“…However, due to embolic complications that occurred two years later, the removal of the left atrial appendage with blood clots was performed. To date, about 150 cases of this defect have been described in the literature[ 5 , 6 ].…”

“…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 ].…”

Case Report: Giant Congenital Left Atrial Appendage Aneurysm Presenting With Acute Massive Cerebral Infarction and Refractory Atrial Fibrillation: A Case Report and Literature Review

“…Congenital LAAA was firstly described in two children by Dr. Parmley in 1962 ( 19 ). Most studies about LAAA are individual case reports ( 4 , 8 , 13 ), and to date, about 150 cases of this defect have been reported in the literature ( 7 , 10 , 20 ). Although this disease is rare, its consequences are potentially hazardous and late diagnosis is common.…”

Diagnosis of a giant left atrial appendage aneurysm by contrast‐enhanced echocardiography: Case report and literature review

“…A recent study demonstrated that aneurysm size did not predict thrombus formation or thromboembolic events, and that thrombus formation could be related to the cardiac rhythm, the size of the LAAA neck, and intra‐aneurismal low‐flow velocity 3 . In spite of a large aneurysm size, patients in sinus rhythm with a large aneurysm neck and blood freely and rapidly flowing between the left atrium and the LAAA, may be exempt of thrombus 6 …”
