- Straight left cardiac border sign
Straight left heart border sign is a described finding on chest radiograph in cases of hemopericardium. It is a fairly specific (84%) sign of hemopericardium after a penetrating chest trauma, although sensitivity at 40% is relatively poor. Positive predictive value (PPV) was found to be 89% 1.
It is different to the flat waist sign of the left heart border seen in left lower lobe collapse.
