Which statement is most accurate regarding cardiac contusion?

Cardiac contusion is a myocardial injury resulting from blunt chest trauma, typically affecting the right ventricle more commonly than the left ventricle because of its anterior location and proximity to the chest wall. The injury can range from mild bruising to severe myocardial damage and dysfunction.

It does not result from myocardial infarction (which is ischemic injury), nor does it cause hypertrophy or hypercontractility. Instead, it may cause wall motion abnormalities, arrhythmias, or even rupture.

These features are detailed in echocardiography and trauma cardiology literature, including the "Textbook of Clinical Echocardiography" and clinical guidelines on blunt cardiac injury【16:Textbook of Clinical Echocardiography, 6e†p.600-605】【12:ASE Trauma Cardiology Guidelines†p.500-505】.
