Penetrating injuries of the heart.
This study represents a review of 33 patients seen at the Kingston Public Hospital, Jamaica, with penetrating cardiac injuries over a 7-year period from 1982 to 1989. Male patients between the ages of 12 and 30 years accounted for more than 80 per cent of cases. A history of syncope associated with haemodynamic instability were the predominant clinical features on presentation. The clinical triad of raised central venous pressure, muffled heart sounds, and low blood pressure levels was present in 33 per cent of the patients with cardiac tamponade. Pulsus paradoxus was not a significant diagnostic sign. Most of the injuries were stab wounds to the left anterior chest. The most commonly injured heart chamber was the right ventricle (48 per cent). Pericardiocentesis was not helpful in making the diagnosis and was only performed as a resuscitative measure in unstable patients prior to thoracotomy. Cardiorrhaphy was performed in the majority of patients through a left anterior lateral thoracotomy with median sternotomy being used only for suspected hilar injuries. A high index of suspicion in patients with penetrating thoracic trauma with expeditious thoracotomy will result in the greatest salvage rate.
