combination of congenital heart defects: 1) constricted pulmonary semilunar valve, 2) interventricular septal opening, 3) emergence of aorta from both ventricles (instead of from left only), and 4) enlarged right ventricle
This congenital heart lesion has four major abnormalities. These are a hole or defect in the ventricular septum (VSD), displacement of the aorta overtop the ventricular septum, hypertrophy of the muscle of the right ventricle and obstruction to blood flow from the right ventricle or right ventricular outflow tract obstruction (which most often results from pulmonary stenosis). Babies with Tetralogy of Fallot are often referred to as 'Tet' babies.
Congenital heart defect characterized by the presence of a ventricular septal defect (VSD) and severe pulmonic stenosis, together with an abnormally positioned aorta and thickening of the right ventricle.
In this condition, a combination of four heart defects keeps some blood from getting to the lungs. As a result, the baby has episodes of cyanosis (a blue or grey discoloration of the skin caused by insufficient oxygen) and may grow poorly. New surgical techniques allow early repair of this complex heart defect.
a congenital heart defect producing cyanosis; characterized by four symptoms: pulmonary stenosis and ventricular septal defect and malposition of the aorta over both ventricles and hypertrophy of the right ventricle
major defect of the heart's chambers and blood vessels leading to and from the heart. The 4 components are: underdeveloped right heart, hole between the lower heart chambers, overriding aorta and underdeveloped pulmonary artery.
A malformation where the right ventricle connects to the pulmonary artery causing pulmonary stenosis with a large ventricular septal defect.
A genetic heart disease involving four structural defects in the heart, which result in insufficient levels of oxygen in the blood.
A congenital cardiac anomaly consisting of four defects: ventricular septal defect, pulmonary valve stenosis or atresia, displacement of the aorta to the right, and hypertrophy of right ventricle. The condition is corrected surgically.
a Ventricular Septal Defect (hole between the two ventricles) and Pulmonary Stenosis - a narrowing between the right ventricle and the artery carrying blood to the lungs
Congenital heart condition characterized by an over riding aorta and right ventricular outflow tract (pulmonary artery) obstruction.
A congenital anomaly, the primary pathophysiologic components of which are obstruction to right ventricular outflow at the infundibular level and a large non-restrictive VSD. The other two components of the "tetralogy" are an over-riding aorta and concentric right ventricular hypertrophy. Valvar RVOTO (pulmonic stenosis) and distal pulmonary artery stenosis are often present. The essential morphogenetic anomaly is malalignment of the infundibular (outlet) septum such that it fails to unite with the trabecular septum (hence the VSD) due to anterior deviation (hence the RV outflow tract obstruction). Lillehei first described the repair in 1955. (Lillehei CW et al. Direct vision intracardiac surgical correction of the tetralogy of Fallot, pentalogy of Fallot, and pulmonary atresia defects; reports of first ten cases. Ann Surg 1955;142:418-445.) pentalogy of Fallot Tetralogy of Fallot with an associated ASD or PFO. pink tetralogy of Fallot Tetralogy of Fallot presenting with increased pulmonary blood flow and minimal cyanosis because of a lesser degree of RVOT obstruction. syn. acyanotic Fallot.
A congenital heart defect that includes a ventricular septal defect, and pulmonary stenosis. Blood received from both R & L ventricels-hypertrophy of R ventricle. Results in "blue baby"
The tetralogy of Fallot is a congenital heart defect which classically has four anatomical components. It is the most common cyanotic heart defect and the most common cause of blue baby syndrome.
