A 25-year-old man, current smoker and cannabis abuser, was admitted to the emergency department for acute chest pain and dyspnea. He had no relevant past medical disease. He was admitted in the Intensive Care Unit at another institution twenty days ago for a cardiac arrest following a traumatic massive left hemothorax after a stab wound. Immediate resuscitation was successful, without no-flow and with a less than 5 min low-flow; left pleural drainage was performed. CT scan control showed multiple parenchymatic contusions and a small right pleural effusion. On day 2, cardiac monitoring showed transient diffuse ST elevation without any chest pain, and troponin I (cTn I) increased up to 16 μg/l (cut-off value of 0.15 μg/l). Transthoracic echocardiography (TTE) showed no pericardial effusion, LVEF was 57% and there was no wall motion abnormality. A cardiac MRI showed neither myocardium rupture, nor pericardial effusion. cTn I concentration decreased and the patient was discharged at day 6 after a second normal echocardiography. At presentation to our institution, heart rate was 115 bpm, blood pressure was 110/75 mm Hg, and blood temperature was 37.9 °C. He had no signs of heart failure or any abnormal cardiac murmur.

X-ray showed widened cardiac silhouette evocative of pericardial effusion that was confirmed by immediate TTE. A CT scan ruled out type A aortic dissection and showed non-proximal right pulmonary embolism, basal left lung contusion and large pericardial effusion (Fig. 1). While he received no anticoagulant or antiplatelet therapy, signs of cardiac tamponade occurred (Fig. 2); a pericardiocentesis by subxiphoid approach was performed under ultrasound guidance and 800 cm3 of active hemorrhagic fluid was collected within 10 min. Immediate sternotomy was performed after general anesthesia and showed 1) hemorrhagic pericardial effusion, 2) multiple pericardial adherences, and 3) a pericardial and myocardial breaches localized at the apex of the left ventricle. After surgical correction of the myocardium breach, drains were placed in left pleural cavity, in retro-sternal area and in pericardial cavity. Twelve hours after surgery, a collapse occurred. Immediate treatment included fluid expansion, norepinephrine, antibiotherapy and heparin therapy for possible massive pulmonary embolism and/or septic shock. TTE showed localized pericardial effusion that involved the left ventricle, with markedly reduced cardiac output. Surgery confirmed localized pericardial effusion that was responsible of left ventricle collapse. After pericardial surgical drainage, he progressively recovered and was discharged two weeks later. Penetrating chest trauma is a very severe and complex condition. Delayed cardiac tamponade after a penetrating chest trauma has been previously reported although it is assumed to be a very rare condition [1–3]. However, post pericardiotomy syndrome and sepsis are the most common cause of delayed pericardial effusion. Our observation is very original as 1) we assume that delayed cardiac tamponade occurred as a consequence of initial penetrating chest trauma. This is suggested by the collection of hemorrhagic fluid and the findings of a myocardial breach at the time of surgery. 2) While ST elevation occurred and cTn-I increased 48 h after the stab wound, myocardial breach remains unnoticed despite repeated echocardiography, MRI examination [4] and CT scan[5]. Overall, our case report emphasizes the need of comprehensive evaluation, possibly including surgical examination, in a large number of patients with acute chest trauma [6,7]. In our observation, we had no evidence of active infection; however, a possible benefit of antibiotic prophylactic treatment has been suggested [8,9].
