Traumatic fistula between the left anterior descending coronary artery and a left ventricular pseudoaneurysm

Post Traumatic Pseudoaneurysm of Left Anterior Descending Artery Presenting as Acute Coronary Syndrome

Penetrating cardiac injuries are highly lethal and carry high mortality rate. Both blunt and penetrating cardiac injuries in patients who survive are known to present with well-known sequelae that often appear days to weeks after the initial insult. In the literature there have been documented cases of cardiac injury induced myocardial infarction, ventricular aneurysms, valvular dysfunction and even fistulous tracts between the coronary vessels and chamber. Although the most commonly injured vessel is the left anterior descending (LAD) coronary artery, traumatic injuries to the left coronary artery result in early death in the majority of cases. We present a unique case of LAD pseudo aneurysm and stenosis presenting as acute coronary syndrome (ACS) months after the initial penetrating cardiac injury successfully managed by stenting. There are only few isolated case reports of coronary artery pseudoaneurysm following penetrating chest trauma published in English literature.

Posttraumatic Left Ventricular Pseudoaneurysm in a Child

A 7-year-old boy developed a left ventricular pseudoaneurysm after being struck by a tractor. The pseudoaneurysm was diagnosed and successfully resected 5 years after the accident.

Traumatic coronary artery fistula management

Traumatic coronary artery-cameral fistulas (TCAF) are uncommon sequelae of trauma that require early surgical intervention to prevent complications. The etiology of traumatic coronary artery-cameral fistulas may be classified as accidental or iatrogenic and have distinctly different courses depending on the etiology. The two operations described for definitive surgical closure of a traumatic coronary-cameral fistula are external ligation/obliteration of the fistula (with or without bypass grafting to the coronary artery distal to the fistula) and direct repair of the fistula from within the recipient chamber. The technique of fistula closure from within the recipient chamber is associated with a reduced incidence of fistula recurrence. A case report and a collective literature review are presented.
