==[[Tetralogy of Fallot]]== 
Tetralogy of fallot is a congenital heart disease comprised of four anatomic features stemming from the malalignment of the infundibular septum: 
#Right ventrifular outflow obstruction (pulmonic stenosis)
#[[Ventricular Septal Defect]]
#Overriding aorta
#Right ventricular hypertrophy

*Clinically, it is a cyanotic heart defect and generally is diagnosed in infancy or early childhood. 

===Echo functions in Tetralogy of Fallot===
*Characterization of defects
*Options for surgical intervention
*Post-operative repair function

===Best evaluated by:=== 
* parasternal long-axis view
* short-axis view (to evaluate size of septal defect)

===Post surgical evaluation should include:===
* Evaluation of VSD repair
* Residual shunting 
* Right ventricular size and contractility
* Right ventricular outflow tract for residual stenosis
* Severity of pulmonary regurgitation
