From Blunt Cardiac Injury to Heart Transplant Following Motorcycle Collision

Area of Science:

• Cardiology
• Trauma Surgery
• Cardiovascular Surgery

Background:

• Blunt cardiac injury (BCI) is a serious condition with diverse pathologies.
• Coronary artery dissection and occlusion are rare but severe complications of BCI.

Observation:

• A 24-year-old male sustained sternal fracture and BCI after a motorcycle accident.
• He developed thrombotic occlusion and dissection of the left anterior descending artery (LAD), requiring mechanical thrombectomy and stenting.
• Subsequent complications included ventricular fibrillation, cardiogenic shock, ischemic cardiomyopathy, and mitral regurgitation, necessitating a heart transplant.

Findings:

• This case highlights the potential for BCI to result in coronary artery dissection and occlusion.
• The progression of cardiac damage ultimately led to the need for heart transplantation, a previously undescribed outcome in this context.
• Mechanical thrombectomy and stenting were initial interventions, but did not prevent long-term cardiac dysfunction.

Implications:

• Clinicians should maintain a high index of suspicion for BCI in patients with relevant trauma.
• Close monitoring and timely diagnostic testing are essential for identifying coronary artery complications.
• Early and aggressive management strategies are critical for improving outcomes in patients with blunt cardiac injury and associated coronary artery pathology.
