Pericardial sinus

The pericardial sinuses are impressions in the pericardial sac formed between the points where great vessels enter it.

Structure

There are three pericardial sinuses: superior, transverse and oblique.

Clinical significance

During pericardial effusion, fluid may build up in the pericardial sinuses. This may be diagnosed with transoesophageal echocardiography.
