Apr 15, 2021 · Of 105 patients with severe blunt chest trauma, only 20 patients (19%) had a suboptimal TTE and underwent complementary TEE. Examination with a TEE could detect an additional 9 cases of myocardial contusion, 4 cases of focal aortic intimal injury, and one case of aortic transection.
Jul 17, 2024 · BCI from blunt chest trauma is most commonly due to motor vehicle collisions (50%), with 20% of all motor vehicle collision deaths involving blunt chest trauma. Other mechanisms, including falls, blast injuries, assault, and other blunt mechanisms, also play a role. [2]

Blunt thoracic trauma is more common than penetrating trauma and represents a significant burden for trauma services. 1 This article provides an overview for clinicians caring for patients with potentially life-threatening blunt thoracic trauma.
Sep 30, 2019 · INTRODUCTION. Blunt cardiac injury (BCI) refers to injury sustained due to blunt trauma to the heart which is more common than penetrating injuries. [1] . Misdiagnosis and high mortality are major concerns in these injuries. The true incidence rate of BCIs varies greatly in the literature.

Cardiac contusions are the most common injuries to the heart resulting from blunt trauma. Mild cardiac contusions often recover without lasting consequences while severe injuries more often result in lasting consequences and mortality . Histologically, it is characterized by a contused myocardium with haemorrhagic infiltrate, localised necrosis, an...
Nonspecific signs and concomitant injuries make the clinical diagnosis of blunt myocardial injury difficult. Signs such as hypotension associated with distended neck veins and muffled heart sounds suggest pericardial tamponade, which may occur with BCI. However, such signs may not be present; the patient with haemorrhage and hypotension may not hav...
Septal injury appears to be rare, and its presentation varies. Septal injury may involve insignificant tears or frank rupture, and may occur in isolation or with valvular injury . Findings may include acute valvular insufficiency with widened pulse pressure and signs of acute heart failure. Isolated valvular injury is likewise rare . The aortic val...
BCI often presents with concomitant injuries. These can include injuries to the head, thorax, abdomen, and spine. In one autopsy series, sternal fractures were found in 76% of cases involving cardiac injury but only 18% of deaths without BCI . Nevertheless, a sternal fracture does not necessarily imply the presence of BCI, but a high degree of susp...
Myocardial infarction is a rare complication of BCI reported in victims of motor vehicle collisions and minor trauma. Causes include coronary artery dissection, laceration, and thrombosis [12, 13]. The left anterior descending artery appears to be involved most often .
Although it occurs in only 20% of all blunt thoracic trauma patients, in patients with severe thoracic injury or multiple injuries, the incidence of BCI may be as high as 76%. Clinical studies looking at BCI in chest and abdominal trauma report incidences significantly lower than in autopsy series.
Aside from chest wall pain due to trauma, many patients with BCI are initially asymptomatic. In the patient with ECG abnormality or shock, it is important to differentiate BCI from acute coronary syndrome, heart failure exacerbation, or other nontraumatic cardiac problem.
