Multimodality Imaging of Giant Right Coronary Aneurysm and Postsurgical Coronary Artery Inflammation.

Multimodality imaging in the evaluation of aorta-right atrial tunnel.

Aorta—right atrial tunnel is a rare congenital anomaly characterized by an extracardiac tunnel-like vascular communication arising from an aortic sinus and emptying into the right atrium (RA) (Fig. 1). We report the case of a 33-year-old man diagnosed following Streptococcus viridans endocarditis. The patient underwent successful surgical repair (Fig. 2). The proximal ostiumwas closed using a p...

Echocardiographic diagnosis of an asymptomatic giant right atrial appendage aneurysm

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 echocardiogr...

Surgical Repair of Giant Right Atrial Aneurysm in a Neonate

Right atrial aneurysm is an extremity rare congenital heart defect. We report a case which was diagnosed during the early fetal stage and operated on in a 2 week old neonate. Following median sternotomy, aneurysmectomy was performed under a cardiopulmonary bypass. Histopathological examination of the resected atiral tissue showed a lipotomatous degeneration and reduction of the muscular element...
