Tetralogy of Fallot, parasternal long axis

This model shows a parasternal long axis echo plane of a heart with the tetralogy of fallot. Tetralogy of Fallot is is a congenital heart defect (a problem considering the structure of the heart that is present by birth). It involves four hear defects: - A large ventricular septal defect (VSD) - Pulmonary stenosis - Right ventricular hypertrophy - An overriding aorta
