Isolated pericardial rupture after blunt chest injury.

A case of isolated pericardial defect, probably due to blunt chest injury, in a symptomless 39-year-old man is described. The diagnosis was based on the clinical finding of an abnormal paradoxic pulsation at the 3rd intercostal space in the absence of auscultatory abnormalities or ischaemic heart disease, and on the characteristic shape of the heart in the plain chest radiograph. Artificial pneumothorax and cardioangiography confirmed the diagnosis.
