Definition
Broadbent sign is a clinical sign characterized by retraction of the left posterior thoracic wall during systole (the phase of the heartbeat when the heart muscle contracts and pumps blood from the chambers into the arteries). This sign is typically observed in patients with constrictive pericarditis, a condition where the pericardium (the sac-like covering of the heart) becomes thickened and rigid, restricting the heart's ability to function properly.
