Aneurysms of the left main coronary artery are a rare entity, being found in 0.1% of angiograms. This case involves a middle aged man with left main coronary aneurysm, complicated with severe obstruction at the ostium of the left anterior descending artery, the ostium of a ramus, and the ostium of the left circumflex artery.

Diagnosis and management of pericardial effusions.

Pericardial effusions are a relatively common phenomenon, largely in part due to its many possible etiologies. Although a considerable amount of cases are idiopathic, careful history and physical examination will reveal the etiology in a vast majority of patients. The most effective tools, echocardiography and right heart catheterization, should be aimed not only at the diagnosis of the pericardial effusion, but also to the assessment of the severity of the pericardial effusion, since this will determine that individual patient's management.
