Left Atrial Appendage Aneurysm Characterized by Multimodal Imaging

We present a four-year-old female with an incidental finding of a congenital left atrial appendage aneurysm who underwent surgical resection with excellent results. This case highlights the importance of multimodal imaging in the diagnosis and characterization of this rare condition.

Left Atrial Appendage Aneurysm

Abstract The left atrial appendage (LAA) aneurysm is a rare condition that can produce local compressive effects and complications including supraventricular tachyarrhythmias, thromboembolic events and myocardial ischaemia. We present a rare case of a neonate with a congenital LAA aneurysm which resulted in local compressive effects on the left ventricle, severe mitral regurgitation and malposition of the left anterior descending (LAD) coronary artery. Intraoperatively, the LAD was found to be within the aneurysmal wall exterior to the left ventricular epicardium and was inadvertently injured during LAA aneurysm resection. Retrospective review of the preoperative computed tomography and echocardiography scans demonstrated the LAD lying within the wall of the LAA aneurysm, although this had not been well appreciated at that time. This highlights the importance of thorough multimodal preoperative imaging and intraoperative assessment for recognition of this rare association between the LAA aneurysm and LAD malposition, and prevention of inadvertent LAD injury during aneurysm resection.

Left Atrial Appendage Aneurysm

A congenital left atrial appendage aneurysm (LAAA) is a rare cardiac malformation that is usually diagnosed in adulthood. It is rarely diagnosed prenatally. In most cases, surgical resection is recommended soon after the diagnosis has been made due to the risk of arrhythmia and thrombotic events. The present report describes a case of LAAA which was prenatally diagnosed and was asymptomatic postnatally. Imaging revealed the relation of the cardiac and airway structures around the LAAA in detail. The patient underwent surgical resection of the LAAA successfully at 7 months of age and is currently healthy at 5 years of age.

Abstract Background While it is the most common thoracic venous anomaly, a persistent left vena cava superior may present in atypical variations, which are important to consider during clinical management. Case presentation Here we report a 35-year-old Caucasian female patient with drainage into the left atrial appendage who presented with shortness of breath accompanied by mild hypoxemia. Venous contrast filling in the context of pulmonary scintigraphy suspected an additional superior caval vein connected to the left atrial appendage. Diagnosis was confirmed by transesophageal echocardiography. Cardiac catheterization revealed a minor right-to-left shunt. The symptoms could be allocated to a bronchial asthma and treated according to guidelines. Cerebral lesions detected in the patient were due to a coincident multiple sclerosis rather than cerebral embolisms. Thus, the venous anomaly was classified as an incidental finding currently requiring no treatment. Conclusions To the best of our knowledge, this is the first report of a persistent left vena cava superior draining into the left atrial appendage.
