- Tetralogy of Fallot
- Mildly hypoplastic pulmonary valve
- Anterior deviation with hypertrophied pulmonary infundibulum into the right ventricular outflow tract (denoted by the star) causing subpulmonary stenosis
- Tetralogy of Fallot
- Mildly hypoplastic pulmonary valve
- Anterior deviation with hypertrophied pulmonary infundibulum into the right ventricular outflow tract (denoted by the star) causing subpulmonary stenosis
- Flow turbulence across the subpulmonary and pulmonary valvar region consistent with stenosis
- Tetralogy of Fallot
- Moderate to severe pulmonary stenosis by spectral Doppler
- peak velocity ~4.2 meters/sec
- peak gradient ~70 mmHg
- Moderate to severe pulmonary stenosis by spectral Doppler
