Study Notes

Overview of Tetralogy of Fallot (TOF)

  • Occurs during fetal development in the womb.
  • Considered a cyanotic heart defect, characterized by reduced oxygen levels in the blood.

Defects in Tetralogy of Fallot

  • Involves four main heart defects represented by the mnemonic RAPS:
    • Right ventricular hypertrophy
    • Aorta displacement
    • Pulmonary stenosis
    • Septal defect (ventricular)

Pathophysiology of Blood Flow

  • Blood flows from the right atrium through the tricuspid valve into the left ventricle, leading to complications.
  • Presence of a ventricular septal defect allows mixing of unoxygenated and oxygenated blood.

Pulmonary Stenosis

  • Narrowing of the pulmonary valve and artery, impeding blood flow to the lungs.
  • This can lead to a right-to-left shunt, increasing the volume of unoxygenated blood in systemic circulation.

Right Ventricular Hypertrophy

  • The right ventricle enlarges due to increased workload.
  • Can lead to severe complications, including heart failure.

Aorta Displacement

  • Enlargement of the aortic valve can result in the displacement of the aorta, contributing to poor oxygenation throughout the body.

Signs and Symptoms

  • Symptoms can be recalled using the mnemonic AFFLICT:
    • Activity leads to cyanosis (Tet spells)
    • Finger clubbing
    • Fatigue during activities
    • Lifting knees to chest decreases right-to-left shunting
    • Inability to grow properly due to hypoxemia
    • Cardiac: presents with a harsh systolic murmur adjacent to the left sternal border
    • Trouble feeding and failure to thrive (FTT), evidenced by poor weight gain

Treatment

  • Surgical intervention is typically required to correct the defects; there may be temporary surgery options available.

Medication

  • Aprostadil (prostaglandin E) is used to manage symptoms and maintain blood flow to the lungs.
