Detailed explanation-1: -A ventricular septal defect (pronounced ven·tric·u·lar sep·tal de·fect) (VSD) is a birth defect of the heart in which there is a hole in the wall (septum) that separates the two lower chambers (ventricles) of the heart.
Detailed explanation-2: -Echocardiogram. This is the most commonly used test to diagnose a ventricular septal defect. Sound waves are used to create pictures of the heart in motion. An echocardiogram can show how well blood is moving through the heart and heart valves.
Detailed explanation-3: -Children born with a VSD have a hole in the heart wall, called the septum, that separates the left and right lower chambers, called the ventricles. If the hole is large, too much blood is pumped into the lungs, making the heart work harder than normal. This may lead to congestive heart failure.
Detailed explanation-4: -The murmur of VSD is typically pan-systolic best heard in the left lower sternal border; it is harsh and loud in small defects but softer and less intense in large ones. Handgrips increase afterload, increasing the strength of the murmur. Infundibular defects are best heard in the pulmonic area.
