Echocardiographic diagnosis of an asymptomatic giant right atrial appendage aneurysm
نویسندگان
چکیده
A 36-year-old man with exertional fatigue was referred to the outpatient department of our hospital for assessment. Transthoracic echocardiogram revealed a large cystic mass close to the right chambers, which compressed the entire right ventricle. The lateral side of the tricuspid valve annulus was displaced because of compression (Fig. 1, 2, Video 1). Additionally, transesophageal echocardiography revealed a thin-walled outpouching cavity (85 x 45 mm) with dense echocardiographic contrast in continuity with the right atrium; this was confirmed as a giant right atrial appendage aneurysm (Fig. 3-5, Video 2, 3). Giant right atrial appendage aneurysm is extremely rare. Because of the risk

Contrast echocardiography in the non-invasive diagnosis of giant aneurysm of the right atrial appendage.
A 57 year-old male patient was admitted to our echocardiography laboratory to rule out thrombus in left atrium before electrical cardioversion of atrial fibrillation. Transoesophageal echocardiography (TEE) demonstrated in the bicaval view, the right atrial appendage measured 10 x 5 cm, area: 42 cm(2), volume: 229 mL (Figure, left). A quick injection of 15 cc of echo-contrast fluid (shaken sali...

Introduction: Cardiovascular diseases are one of the leading causes of mortality in today’s industrial world. Occlusion of left atrial appendage (LAA) using the manufactured devices is a growing trend. The objective of this study was to develop a computer-aided diagnosis system for the identification of LAA in echocardiographic images. Method: The data used in this descriptive analytical study ...

متن کاملA case of right atrial appendage aneurysm mimicking a pericardial cyst on echocardiogram
UNLABELLED Right atrial appendage aneurysms (RAAAs) are rarely encountered. If symptomatic, they present with atrial arrhythmias or embolic events. Surgical resection is indicated for symptomatic patients. We describe a 65-year-old man presenting with palpitation for 6 months. Electrocardiogram showed atrial flutter. Transthoracic echocardiography revealed a large thin-walled cystic mass anteri...
متن کاملA Semi-Automated Algorithm for Segmentation of the Left Atrial Appendage Landing Zone: Application in Left Atrial Appendage Occlusion Procedures
Background: Mechanical occlusion of the Left atrial appendage (LAA) using a purpose-built device has emerged as an effective prophylactic treatment in patients with atrial fibrillation at risk of stroke and a contraindication for anticoagulation. A crucial step in procedural planning is the choice of the device size. This is currently based on the manual analysis of the “Device Landing Zone” fr...
