Question

Quizplus · Accepted Answer

Ventricular septal defect (VSD) is a congenital heart defect that occurs when there is a hole in the wall (septum) that separates the two ventricles of the heart. This hole allows oxygenated blood from the left ventricle to mix with deoxygenated blood in the right ventricle, which can lead to a loud, harsh, holosystolic murmur and systolic thrill that can be detected at the left lower sternal border and radiates to the neck.
