Pericardial Mass as a Rare Cause of Unstable Angina in a Young Veteran.

ABSTRACT:

Clinical condition

A 35-year-old healthy male veteran presented with angina, shortness of breath with exertion, and near-fainting episodes. A transthoracic echocardiogram showed a septated cyst compressing the left ventricle. Cardiac magnetic resonance imaging and computed tomography angiography confirmed the presence of a pericardial cyst measuring 7.9 × 4.4 × 4.1 cm, located just 2 mm from the left anterior descending artery.

Key questions

1) Was the pericardial cyst the cause of his symptoms? 2) Does its location affect the left anterior descending artery? 3) Is diastolic collapse of the left ventricle related to the symptoms?

Outcome

The veteran underwent a robot-assisted excision of the pericardial cyst, which was completed without complications, leading to the c
