ABSTRACT
Objective:To summarize the ultrasonophic features of left atrial appendage aneurysm, and to provide an important reference for the early and accurate diagnosis of left atrial appendage aneurysm.Methods:Patients with atrial appendage aneurysm have no obvious symptoms in the early stage, and there are many difficulties and challenges in diagnosis. This paper analyzed and summarized the diagnostic characteristics of a child with left atrial appendage aneurysm by combining the prenatal and postnatal ultrasonic imaging characteristics.Results:Echocardiography is the first choice for the diagnosis of left atrial appendage aneurysm. Some cases can make precise diagnosis prenatally.Conclusions:Echocardiography is the preferred imaging examination method for evaluating left atrial appendage aneurysm. Multimodal imaging technology can identify and diagnose left atrial appendage aneurysm early and accurately, and provide important basis for clinical diagnosis and treatment plan.
ABSTRACT
Left atrial appendage (LAA) aneurysm is a rare, pathologic condition that may lead to atrial tachyarrhythmia or thromboembolic events. A 49-year-old man presented with aggravated palpitation and dizziness. He suffered from refractory atrial fibrillation despite a previous history of radiofrequency catheter ablation. Echocardiography revealed a 57-mm LAA aneurysm. Surgical ablation was performed through a right mini-thoracotomy, and the LAA aneurysm was obliterated with a 50-mm AtriClip (Atricure Inc., Westchester, OH, USA). However, follow-up computed tomography showed residual communication, so the patient is still taking warfarin. We report that a minimally invasive strategy for treating LAA aneurysm can be considered, but incomplete closure may occur; thus, caution is needed.
