Prominent crista terminalis mimicking a right atrial mass: case report
نویسندگان
چکیده
The crista terminalis is a normal anatomical structure within the right atrium that is not normally visualised in the standard views obtained while performing a transthoracic echocardiogram. In this case report, transthoracic echocardiography suggested the presence of a right atrial mass in a patient with end stage renal disease. However, subsequent transesophageal echocardiography revealed that the right atrial mass was actually a thick muscular bridge in the right atrium consistent with a prominent crista terminalis. An understanding of the anatomy and the echocardiographic appearance of a prominent crista terminalis will minimize the misdiagnosis of this structure avoiding unnecessary expensive additional tests.

Crista terminalis bridge: a rare variant mimicking right atrial mass.
Prominent crista terminalis is a variant of normal heart anatomy mimicking right atrial mass-like tumour, thrombus, or vegetation. The case report depicts a rare kind of this structure that constitutes a thick muscular bridge in the right atrium. Detection by 2D and 3D echocardiography can avoid further useless investigation.

A prominent crista terminalis is a normal anatomic variant which consist of thick muscular bridge within the right atrium. However, it could be often misdiagnosed with an abnormal mass on the transthoracic echocardiography. The case report presented here, describe the findings of transthoracic echocardiography that suggested a right atrial mass in patients with pulmonary embolism. However, subs...
متن کاملA prominent crista terminalis associated with atrial septal aneurysm that mimics right atrial mass leading to atrial arrhythmias: a case report
UNLABELLED INTRODUCTION The crista terminalis is a variant of normal anatomical structures within the right atrium that mimics an atrial mass on a transthoracic echocardiogram. Atrial septal aneurysm is a rare but well-recognized cardiac abnormality of uncertain clinical significance. The association between crista terminalis and atrial septal aneurysm is unusual but not completely casual. B...

A 68-year-old woman came to our observation with a clinical history of isolated systolic hypertension poorly controlled by the combination of ramipril 5 mg and hydrochlorothiazide 12.5 mg o.d. The ECG showed sinus rhythm with heart rate of 68 beats per minute and signs of left ventricular hypertrophy without strain. Further investigation included an echocardiogram that showed normal left and ri...
متن کاملProminent crista terminalis and Eustachian ridge in the right atrium: Two dimensional (2D) and three dimensional (3D) imaging.
The crista terminalis and Eustachian ridge are normal anatomical structures within the right atrium that are not normally looked for or visualised in the standard views obtained while performing a transthoracic echocardiogram (TTE). In this case report, the prominent terminal ridge (a normal anatomical variant) appeared as a "mass" in the right atrium that needed to be differentiated from a pat...
