Traumatic right coronary arterial-right atrial fistula.
A healthy 25 year old man presented with a machinery murmur and a history of a penetrating thoracic injury. Hemodynamic and angiographic evaluation demonstrated a fistula from the right coronary artery to the right atrium that was later successfully repaired. This case and similar reported cases indicate that fistula formation is a late complication of penetrating thoracic injuries. The onset of the murmur occurs with enlargement of the fistula and typically is delayed for several weeks to months after the initial injury.
