Patients with penetrating cardiac injuries present in a stable or only mildly shocked condition--especially if the laceration has sealed off and the patient has been adequately resuscitated. A large proportion of patients presenting to our unit are in a reasonably stable condition after resuscitation, and rapid diagnosis may be difficult. We present our experience over a 5-year period (191 patients), with particular reference to the stable patient. ⋯ Cardiac ultrasound is very useful (in the absence of haemothorax), and was performed in 103 of 191 patients, with 8 false-negatives and 3 false-positives. When an unstable patient presents with an obvious diagnosis use of cardiac ultrasound should be restricted. A subxiphoid window has diagnostic value where the cardiac ultrasound is inconclusive.
