A.Valvular stenosis
B.Infundibular stenosis
C.Over riding of aorta
D.RVH
The correct answer is A.Valvular stenosis
Right ventricular outflow obstruction is one of the characteristic of tetralogy of Fallot.
Pulmonary valve stenosis(alone) rarely contributes to the right ventricular outflow obstruction in Tetralogy of Fallot.
Note:Tetralogy of Fallot (TOF) is one of the most common congenital heart disorders (CHDs). This condition is classified as a cyanotic heart disorder, because tetralogy of Fallot results in an inadequate flow of blood to the lungs for oxygenation (right-to-left shunt).
The 4 features typical of tetralogy of Fallot include right ventricular (RV) outflow tract obstruction (RVOTO) (infundibular stenosis), ventricular septal defect (VSD), aorta dextroposition, and right ventricular hypertrophy.
