Key result
Blunt chest trauma linked to perfusion-metabolism mismatch and life-threatening arrhythmias in a 37-year-old man.
Why the study?
Blunt cardiac injury can cause life-threatening arrhythmias, but the role of perfusion–metabolism mismatch detected by dual myocardial scintigraphy is not well characterized.
Case Report (n=1)
Blunt cardiac injury can cause perfusion-metabolism mismatch detectable by dual myocardial scintigraphy, which may be associated with the development of life-threatening arrhythmias.
May alert clinicians to metabolic mismatch in post-traumatic arrhythmias; leaves open validation in larger cohorts.
Patient A healthy 37‐year‐old man who bruised his chest with a steel frame developed ventricular fibrillation, pulseless ventricular tachycardia, and temporary torsade de pointes, and was resuscitated with emergency medical treatment. Thallium 201 scintigraphy 7 days later revealed a defect only in a small area of the apex, whereas 123I‐beta‐methyl iodophenyl pentadecanoic acid scintigraphy showed defects in a larger area of the apex, ventricular septum, and inferior wall, indicating perfusion–metabolism mismatch. Follow‐up dual myocardial scintigraphy on day 49 showed that the scintigraphic defects persisted only at a small area of the apex. Conclusion Blunt external force appeared to have caused perfusion–metabolism mismatch and subsequent life‐threatening arrhythmias in this patient.

Morikawa et al. (2013) conducted a case report in Blunt cardiac injury (n=1). Blunt external force (chest trauma) was evaluated on Perfusion-metabolism mismatch and life-threatening arrhythmias. Blunt external force to the chest caused perfusion-metabolism mismatch and subsequent life-threatening arrhythmias in a 37-year-old man.
