Which part of the heart is most likely to become injured in a blunt cardiac injury (cardiac contusion)?

Bundle of His
Right ventricle
Left ventricle
Bicuspid valve

Explanation

Answer: B- In cases of cardiac contusion, the right ventricle is more vulnerable to injury than the left ventricle, the bundle of His, and the bicuspid valve.

Due to its proximity to the sternum and position in the chest, the right ventricle is most likely to take the brunt of the impact on the heart in blunt chest trauma.
