P64 covered stent in a chest trauma: congenital coronary arterial fistula or traumatic coronary perforation?

Abstract Coronary arterial fistula consists in a communication between a coronary artery and a cardiac cavity. It is tipically a congenital condition, but it can also be a result of invasive cardiac procedure. Although chest truama generally evolve to massive pericardial effusion, in some cases it can determine also a coronary perforation, with a consequent coronary arterial fistula. A 22–year–old male patient, with no cardiovascular history, was admitted after a road accident, reporting pelvis break, 17 costal break, and sternal break, with consequent chest pain. On admission the patient had a heart rate of 100 b.p.m. and a blood pressure of 130/80 mmHg. Elettrocardiogram (ECG) reported ST elevation in antero–septal derivations (V1–V4). Echocardiogram showed a global left ventricular (LV) ejection fraction of 55%, with an apical–septal akinesia, with a minimal anterior pericardial effusion, not emodinamically significant. So, an emergency coronary angiography was performed, showing a fistula of the distal segment of the left anterior discendent coronary (LAD). In this case there were two possible options, a previously unknown congenital coronary arterial fistula, or a traumatic coronary perforation, determining a coronary arterial fistula. Considering the possibility of a traumatic coronary perforation, with the consequent risk of rapid pericardial effusion worsening, the decision was to perform percutaneous coronary intervention (PCI) with a covered stent (Biotronik Papyrus 2.5 x 20 mm, 8 atm), with a good final result, with total occlusion of fistula. At 1 month follow up, the patient was asymptomatic for dyspnea or chest pain, with a heart rate of 70 b.p.m. and a blood pressure of 130/80 mmHg. ECG showed no anomalies in ST–T tract.
