Traumatic Coronary Artery Dissection with Secondary Acute Myocardial Infarction after Blunt Thoracic Trauma

Coronary artery intramural hematoma causing myocardial infarction mimicking pseudoaneurysm or dissection from trauma: A case report

Blunt chest trauma caused ST-segment elevation myocardial infarction. Diagnosis of intramural hematoma (IMH) using computed tomography was confirmed using electrocardiography, cardiac marker tests, and subsequent coronary angiography. After conservative treatment, the hematoma was completely resolved 1 year later. Differentiating IMH from other arterial injuries is critical for appropriate management.

Delayed acute myocardial infarction in a young man with traumatic multivessel coronary artery dissection after blunt chest injury

A man in his 20s with no medical illness sustained a blunt chest injury with pneumothorax and lung contusion after involving in a motorbike accident. Five days postadmission, he subsequently had myocardial infarction with cardiac arrest, in which coronary angiogram and intravascular ultrasound showed diffused multivessel coronary artery dissection.

Traumatic coronary artery dissection misdiagnosed as stress-induced cardiomyopathy in a patient with multiple trauma

Traumatic coronary artery dissection resulting from blunt trauma, is a relatively rare and life-threatening event. We present a case report of a 42-year-old male who presented with electrocardiogram abnormality and cardiac enzyme elevation following a fall from a height of 3 m. The patient was misdiagnosed with stress-induced cardiomyopathy because of the absence of clinical signs of acute coronary syndrome. The patient was subsequently diagnosed with traumatic coronary artery dissection using coronary angiography, and the relevance of the trauma was confirmed using intravascular ultrasonography (IVUS). Herein, we highlight that trauma team should maintain a high suspicion of traumatic coronary artery dissection, although the early recognition of traumatic coronary artery dissection can be difficult. Additionally, the importance of coronary angiography with IVUS modalities for the evaluation of traumatic coronary artery dissection is highlighted.

Traumatic left main coronary artery dissection in a young adult following blunt chest trauma – A case report

Blunt chest trauma may cause variable degrees of thoracic injuries. Most of the patients may remain asymptomatic after sustaining blunt chest trauma. But in rare instances, life-threatening conditions such as coronary artery dissection may occur. The authors present a 29-year-old male adult with persistent chest pain following blunt trauma with a rise in cardiac troponins and elevated ST segment in ECG. Coronary CT and conventional angiography demonstrated dissection of the left main coronary artery. It is deemed necessary to suspect cardiac injury in patients with a history of blunt chest trauma in appropriate clinical settings. Early recognition of coronary artery dissection is vital to reduce morbidity and mortality. ECG combined with cardiac enzymes can be essential tools helping the physicians raise the suspicion towards a cardiac injury followed by cross-sectional and conventional angiographies for confirmation.

Blunt traumatic coronary artery dissection: A case study

Background

Coronary artery dissection is an extremely rare but lethal complication of blunt chest trauma. Dissection may cause thrombus formation or vasospasm, leading to the clinical presentation of acute myocardial infarction. Diagnosis can be difficult as traumatic chest pain has several etiologies; therefore, an electrocardiogram (ECG) is necessary in all cases of thoracic trauma [1-3].

Case report

Thirty-eight-year old female, with no significant past medical history, presented to a freestanding emergency department with complaints of severe chest pain and right shoulder pain after a blunt trauma water sport accident. Upon selective angiography of left and right coronary artery and left heart catheterization, the patient was found to have an occluded distal left anterior descending artery (LAD). The patient underwent aspiration thrombectomy of the proximal LAD artery and percutaneous transluminal coronary angioplasty (PTCA) of distal LAD artery, which decreased the stenosis from 100% to less than 10%. The patient was discharged home on hospital day three with follow up in one month.Coronary artery dissection should be considered in blunt thoracic trauma particularly in cases of unexplained chest pain, regardless of the mechanism of injury, age of patient or comorbidities. Patients should be evaluated with an ECG, troponin, and possibly an echocardiogram to rule out this type of injury.

Traumatic mitral annular avulsion and interventricular septum dissection

We presented a rare case of traumatic mitral annular avulsion and interventricular septum dissection after an unintentional falling injury in a 5-year-old female child. A successful surgical repair of mitral annulus and interventricular septum was performed to restore the haemodynamic stability.

Blunt-chest-trauma-induced acute myocardial infarction

Blunt chest trauma (BCT) is one of the rarest causes of acute myocardial infarction (AMI). This paper reports the case of a young married man who suffered from AMI due to BCT sustained in a fight with his wife. The histopathology examination revealed a rupture of atherosclerotic plaque with superimposed thrombus in the proximal left anterior descending artery. This report also reviews previously reported BCT-induced AMI cases in the literature.

Early Recanalization of a Traumatic Coronary Artery Dissection With Medical Therapy Alone

We describe a patient who presents with chest discomfort 30 h after having an accident with an all-terrain vehicle. His follow-up coronary computed tomography angiogram revealed early recanalization of his coronary artery with conservative medical therapy. (Level of Difficulty: Intermediate.)

Multivessel Traumatic Coronary Artery Dissection After a Motor Vehicle Accident With Successful Percutaneous Coronary Intervention

Coronary artery dissection is a rare complication of blunt chest wall trauma. We report a case of acute left anterior descending and right coronary artery dissections after a motor vehicle accident. The musculoskeletal injuries obscured the cardiac symptoms. Electrocardiogram and bedside echocardiogram revealed cardiac pathology, which prompted urgent coronary angiography and intervention. (Level of Difficulty: Advanced.)

Traumatic Right Coronary Artery Dissection as a Cause of Inferior Wall ST-Elevation Myocardial Infarction

Blunt cardiac injury, causing coronary artery dissection in the absence of other forms of injury to the heart or lungs is a rare occurrence. Here we present a case of a 41-year-old male who presented with right coronary artery (RCA) dissection after blunt chest trauma. The patient initially presented with chest pain and was diagnosed with an inferior wall myocardial infarction (MI). He then developed a complete heart block and bedside echocardiogram showed right ventricular akinesis. Immediate coronary angiography showed RCA dissection, and TIMI 3 flow was established after the placement of four drug-eluting stents. Blunt trauma-induced RCA dissection is associated with high mortality which needs immediate treatment. Hence through this case report, we would like to stress the importance of having a high index of suspicion for this condition in patients with a blunt chest injury.

Traumatic coronary artery dissection leading to ventricular tachycardia

Traumatic coronary artery dissection is an unusual injury following trauma. It is potentially life threatening and requires prompt recognition on presentation. We present a case report of a 42-year-old male who presented with ventricular tachycardia following a high-speed motorcycle collision that was found to have a coronary artery dissection. The patient had multiple complications, highlighting the importance of early recognition of this disease process.
