**Core Concept**
Subendocardial hemorrhages are a type of cardiac injury that involves bleeding into the subendocardial layer of the heart, which is the innermost layer of the heart muscle. This condition can be caused by various factors, including cardiac contusion, electrical cardioversion, or severe hypertension. Subendocardial hemorrhages can be an important finding in forensic medicine, as they can be indicative of non-accidental trauma.

**Why the Correct Answer is Right**
The correct answer, **Option B: Involves the right ventricular wall**, is incorrect because subendocardial hemorrhages typically occur in the left ventricular wall. The left ventricle is more susceptible to subendocardial hemorrhages due to its thicker wall and higher pressures. The right ventricle, on the other hand, has a thinner wall and lower pressures, making it less prone to subendocardial hemorrhages.

**Why Each Wrong Option is Incorrect**
**Option A: May be seen after head injury**, is incorrect because subendocardial hemorrhages are not typically associated with head injuries. While head injuries can cause cardiac contusion, the resulting hemorrhages are more likely to be epicardial or pericardial rather than subendocardial.

**Option C: Continuous pattern**, is incorrect because subendocardial hemorrhages typically have a patchy or segmental distribution rather than a continuous pattern. The pattern of hemorrhage can vary depending on the underlying cause and the location of the injury.

**Option D: Flame shaped hemorrhages**, is incorrect because subendocardial hemorrhages are not typically described as flame-shaped. The appearance of subendocardial hemorrhages can vary depending on the location and extent of the injury, but flame-shaped hemorrhages are not a characteristic feature of this condition.

**Clinical Pearl / High-Yield Fact**
Subendocardial hemorrhages are more common in individuals with pre-existing cardiac conditions, such as hypertension or coronary artery disease. It is essential to consider the patient's medical history and the mechanism of injury when evaluating cardiac injuries in a forensic context.

✓ Correct Answer: B. Involves the right ventricular wall
