Continuous murmur is found in all, EXCEPT
**Core Concept**
A continuous murmur is a type of heart murmur that occurs throughout the cardiac cycle, without interruption. This phenomenon is typically associated with **patent ductus arteriosus**, **aortic regurgitation**, and **coronary arteriovenous fistula**. The underlying principle involves abnormal communication between high-pressure and low-pressure systems.
**Why the Correct Answer is Right**
The correct answer choice is not provided, however, continuous murmurs are classically heard in conditions where there is a constant flow of blood from a high-pressure artery to a low-pressure vein or another artery throughout systole and diastole.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option details, we cannot determine why it is incorrect.
**Option B:** Similarly, without details, the reasoning behind its incorrectness cannot be provided.
**Option C:** The same applies here, as the option text is missing.
**Option D:** Again, the absence of the option text makes it impossible to explain why it is incorrect.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that continuous murmurs are often associated with **shunts** or **fistulas** that allow blood to flow continuously from a high-pressure system to a low-pressure system.
**Correct Answer:** Not provided in the query.
