Abstract

A left atrial appendage aneurysm is a very rare medical condition which can develop by an inflammatory reaction or a degenerative change. If there is no accompanying anomaly, a left atrial appendage is considered a congenital disease. The majority of left atrial appendage aneurysms are detected incidentally because they usually do not cause any symptoms. Surgery is indicated, even for asymptomatic patients, because of the risk of life-threatening complications, such as atrial fibrillation, supraventricular tachycardia, systemic embolization, and cardiac arrest. Left atrial appendage aneurysms are usually treated by a median sternotomy with extracorporeal circulation, especially if the aneurysm has a broad base or contains a thrombus, but can treated by thoracotomy without extracorporeal circulation. We report a case of a successfully treated left atrial appendage aneurysm that was misdiagnosed as a partial pericardial defect without extracorporeal circulation in a 13-year old child.

좌심방 부속지류는 매우 드문 질환으로 염증반응이나 퇴행성 변화로 발생할 수 있지만, 동반된 다른 기형이 없을 경우 선천성으로 생각할 수 있다. 선천성 좌심방 부속지류는 대부분 증상이 없어 우연히 발견되지만, 심방 세동, 상심실성 빈맥, 전신 색전증상, 심정지 등 합병증이 발생할 수 있어 진단되면 증상이 없어도 수술을 권장하고 있다. 개흉술을 통해 접근이 가능하지만, 기저부가 넓은 경우나 좌심방 부속지내에 혈전이 있는 경우에는 체외순환이 필요해 정중흉골 절개술이 필요할 수 있다. 저자들은 부분 심낭 결손증으로 오인되었던 선천성 좌심방 부속지류를 좌측 개흉술을 통해 체외순환 없이 성공적으로 수술하였기에 증례 보고를 하는 바이다.
