Ultrasound of the pericardial sac may be associated with a false negative result in the presence of a hemothorax. A filling in of the left heart border inferior to the pulmonary artery, called the straight left heart border (SLHB), is a radiological sign on chest X\u2010ray that we have found to be associated with the finding of a hemopericardium at surgery. The aim of the present study was to determine if this was a reliable and reproducible sign.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This was a prospective study of patients with a penetrating chest injury admitted between 1 October 2001 and 28 February 2009, who had no indication for immediate surgery, and were taken to the operating room for creation of a subxiphoid pericardial window (SPW).
