Ventricular Septal Defect

  • Etiology: types – outlet / supracrystal (5%) associated with truncus arteriosus + Tetralogy of Fallot, menbranous (80%), inlet (5%) associated with AV canal, muscular (10%)
  • Clinical: most common congenital heart disease, 33% resolve spontaneously, present in second month when pulmonary vascular resistance decreases and a shunt can develop so therefore most common cause of shunt vascularity in infants + children but not in neonates
