1. TOF encompasses a wide spectrum of abnormalities beyond the classic findings of RVH, PS, VSD and Overriding Aorta, including subvalvar RVOT stenosis, branch pulmonary artery stenoses and aneurysms, aortopulmonary collaterals and airway complications. 2. The postoperative appearance is variable depending on disease severity and surgical technique. 3. What quantitative parameters and imaging findings need to be reported by radiologists.

I. Spectrum of TOF. a. All forms: big VSD b. Mild: mild PS, normal PAs (VSD physiology) c. Moderate: subpulmonic or pulmonic stenosis, normal PAs (classic TOF) d. Severe: Severe subpulmonic stenosis or pulmonic atresia, hypoplastic PAs with PDA (duct-dependent) e. Very severe: Pulmonic atresia, absent pulmonary arteries, MAPCA f. TOF with absent pulmonary valve: Airway obstruction, severe PI, large MPA and branch PAs. II. Early palliation. a. Balloon angioplasty/stenting b. BT shunt c. Transannular patch, VSD closure d. Valve sparing RVOT augmentation, PA augmentation e. Homograft or RV to PA conduit f. Unifocalization, RV to PA conduit III. Adult evaluation. a. RVEF and EDV b. Pulmonic Regurgitant fraction c. RVOT and PAs d. Retrosternal anatomy. IV. Late intervention. a. Valve placement surgical/transcatheter b. Homograft replacement c. Pulmonary artery patching.
