This condition often presents with a systolic, diamond-shaped ('crescendo-decrescendo') murmur. The murmur described in this case is continuous and machine-like.

Just like aortic stenosis, this typically presents with a crescendo-decrescendo murmur. It does not match the continuous and machinery murmur described in this scenario.

This condition presents with a holosystolic murmur, not a continuous, machine-like murmur as explained in the scenario.

A murmur resulting from a VSD will be pansystolic and prominent at the lower left sternal border
