Determine if PA needs to be removed or if removing the excessive muscle tissue will help to function correctly. Additionally, an atrial septal defect was found on necropsy, resulting in the final diagnosis of Tetralogy of Fallot with an atrial septal defect (a subclass of Pentalogy of Fallot). Tetralogy of Fallot (TOF) encompasses a spectrum of cardiac defects that stem from anterocephalad deviation of the outlet septum, along with abnormal septoparietal trabeculations which contribute to right ventricular infundibular narrowing.

TETRALOGY OF FALLOT It is a rare condition caused by a combination of four heart defects that are present at birth (congenital). The role of echocardiography, conventional X-ray, CT and MR techniques and nuclear imaging will be discussed below. LV overload is curtailed but at the cost of cyanosis 90% of cases PHYSIOLOGY When the great arteries are normally related, When VSD is non restrictive and pulmonary vascular resistance is low PBF and LV volume over load - excessive Cyanosis is mild Tetralogy of Fallot is a type of congenital heart defect. With the advent of fetal echocardiography (ultrasound scanning of the unborn child's heart), the diagnosis can sometimes be made before the child is born. Breath-hold electrocardiographically gated cardiac magnetic resonance (MR) imaging and contrast material-enhanced MR angiography are emerging as ideal techniques for the evaluation of complex congenital heart disease. This leads to the four well-known components of TOF: Anterior malalignment ventricular septal defect (VSD) TOF is frequently associated with chromosomal and extracardiac anomalies, and cases with severe obstruction of the pulmonary tract very often require assessment and treatment immediately after birth. Physical Examination Essential abnormal cardiac findings in severe tetralogy of Fallot: cyanosis and systolic ejection murmur with a single second heart sound Overt clubbing of fingers and toes typically not detected until 2-3 months of age The baby may be normally grown, although a higher proportion weighs less than would be expected by chance
