Ventricular Septal Defect (VSD)

The commonest heart defect ("Hole in the heart"). When small, such defects cause little in the way of problems and often "heal" (close) on their own. Blood flows from left ventricle to right ventricle at high pressure, often producing a loud "murmur" with each heart beat. The effect on heart function depends on the size of the defect, but may be very minor. Surgery may not be required, if the heart shows no evidence of "strain".

Larger VSDs allow more blood to flow from the left ventricle to the right ventricle and lead to increase in pressure and flow in the lung circulation. This places significant strain on the heart and affected babies usually need surgical repair of the defect. An operation may be required in the first three to four months of life, though some defects, which are causing less trouble, may be left for a few years, in the hope that they may get smaller, only needing surgery if they remain large or are associated with other problems.
