Tetralogy of Fallot is the most common heart defect in children which ultimately leads to the child's blood not being fully oxygenated. In tetralogy of Fallot ( TOF ), four related heart defects change the way blood flows to the lungs and through the heart. Tetralogy of Fallot (TOF) could be a internal organ anomaly that refers to a mix of 4 connected heart defects that ordinarily occur together.Tetralogy of Fallot (pronounced te-tral Some babies have heart defects because of changes in their genes or chromosomes.

Tetralogy of Fallot (TOF) with absent pulmonary valve is a rare congenital anomaly characterized by features of tetralogy of Fallot with either rudimentary ridges or the complete absence of pulmonic valve tissue. A common genetic condition with tetralogy of Fallot (seen in about 1520 % of cases) is deletion 22q11, a condition in which a small part of chromosome 22 is missing. Tetralogy of Fallot is a heart condition youre born with that makes it hard to get enough oxygen to your body because of four abnormalities in your hearts structure. The blood from the right ventricle preferentially enters the aorta which is overriding the ventricular Borgeskov, S, et al. Untreated Fallots tetralogy can lead to several complications including: Recurrent cyanotic spells. The TOF changes in a baby's heart develop in the early weeks of pregnancy. What are the complications of tetralogy of Fallot?Blood clots (which may be in the brain causing stroke)Infection in the lining of the heart and heart valves (bacterial endocarditis)Abnormal heart rhythms (arrhythmias)Heart failure.Death.

Some infants need more than one heart surgery. The perioperative mortality has reduced significantly in the current era (<4%) 1 but the long-term survival is still not equal to the general population. Anatomy Tetralogy of Fallot (TOF) is a form of cyanotic congenital heart disease (CHD) that encompasses four anatomic features ( figure 1) (see 'Anatomy' above): Prevalence The prevalence of TOF is approximately 4 per 10,000 live births. TOF is a defect combining 4 abnormal- Tetralogy of Fallot (TOF or "TET") is a combination of four congenital heart defects, including: Ventricular septal defect (VSD) - an opening in the ventricular septum, or dividing wall between the two lower chambers of the heart known as the right and left ventricles. Echocardiography 2013; 30:81. Poor growth and development. Tetralogy of Fallot is a complex congenital heart defect characterized by a large ventricular septal defect (hole between the right and left ventricles), pulmonary stenosis It occurs equally as often in males and females. Borgeskov, S, et al. All the features of tetralogy of Fallot result from anterosuperior displacement of the infundibular septum leading to abnormal septation between the pulmonary trunk and the aortic root. Introduction.

The infant or child will then Whatever the cause of Fallots tetralogy, it is present from birth and, in fact, from very early on in the pregnancy (possibly the 7th week after conception). Overview:-. The hemodynamics of tetralogy of Fallot depend on the degree of right ventricular (RV) outflow tract obstruction (RVOTO). But sooner or SUMMARY AND RECOMMENDATIONS. Tetralogy of Fallot is the infrequent condition that is caused by an amalgamation of four heart defects that are congenital (present at the birth). Current strategy of repair of tetralogy of Fallot in children and adults: emphasis on a new technique to create a monocusp-patch for reconstruction of the right ventricular outflow tract. Tetralogy of Fallot is treated with two kinds of surgery. Tetralogy of Fallot is 4 congenital heart defects. This imperfection affects the heart Tetralogy of Fallot (TOF) includes the following major features : Right ventricular outflow tract (RVOT) obstruction Malalignment ventricular septal defect (VSD) Suppl 2:115-8. These episodes are called tet spells. In some Tetralogy of Fallot is a rare, complex congenital heart defect, meaning that it is present at birth. Congenital heart defects are relatively common overall. One provides temporary improvement by a shunt to give more blood flow to the lungs. Tetralogy of Fallot causes low oxygen levels in the blood. Tetralogy of Fallot (TOF) is a common defect in which obstruction to the flow of blood from the heart to the lungs causes low oxygen levels in the blood. Tetralogy of Fallot (TOF) is a common defect in which obstruction to the flow of blood from the heart to the lungs causes low oxygen levels in the blood. A pathogenetic mechanism for the formation of tetralogy of Fallot is postulated. Borgeskov S, Brockner J, Poulsen T, et al.

Danish Medical Bulletin, vol. We propose that the right ventricular ejection stream is divided into a transseptal aortic stream and an infundibular pulmonary stream during embryonic life before the ventricular septum is closed. Pulmonary stenosis (right ventricular outflow obstruction) 3.

Tetralogy of Fallot is 4 congenital heart defects. The key morphological abnormality is anterior and cephalad deviation of the muscular outlet of the ventricular septum, which causes the 4 classic findings: (1) a mal-alignment ventricular septal defect (VSD), (2) aorta over-riding the VSD, (3) right ventricular outflow tract obstruction, (4) Tetralogy of Fallot Causes. Tetralogy of Fallot is a complex heart disease with four components: pulmonic stenosis, ventricular septal defect, right ventricular concentric hypertrophy, and dextropositioned (overriding) aorta. Right-to-left shunting across the ventricular septal defect may result in generalized cyanosis and polycythemia. Bhat AH, Kehl DW, Tacy TA, et al. INTRODUCTION.
