How Can A PDA be fixed?
It can be closed either with surgery or with non-surgical techniques. Surgical ligation of PDA does not require use of cardiopulmonary bypass. Non-surgical techniques involve closing the ductus with the use of stainless steel coils or an umbrella made of a material called nitinol. VENTRICULAR SEPTAL DEFECT (VSD): It is a defect in the partition separating the two ventricles. Usually, the left ventricle (LV) pressures are higher than the right ventricle (RV) ones. Hence the blood flows from the LV to the RV through the defect. This results in oxygenated, pure blood going back into the lungs, resulting in the heart having to pump an extra amount of blood. However, if a large defect is left untreated, the pressure in the lung arteries tends to increase. This results in impure blood from the RV flowing into the LV and subsequently into the body. SYMPTOMS depend upon the size of the hole and the pressure in the RV. During the newborn period, the pressures in the RV are high and the child ma
