Can Tetralogy Of Fallot Cause Heart Failure?

Most heart failure seen in patients with TOF (of all ages) is mediated, at least in part, by pulmonic insufficiency. Nevertheless, there is a trend toward increased numbers of TOF patients developing biventricular or left-sided heart failure in the absence of significant pulmonic valve dysfunction.

What is the most common complication found in patients with tetralogy of Fallot?

Early postoperative complications following repair of tetralogy of Fallot (TOF) include the creation of heart block and residual ventricular septal defects (VSDs). Ventricular arrhythmias are more common and are reportedly the most frequent cause of late postoperative death.

How does Tetralogy of Fallot affect the heart?

Tetralogy of Fallot (teh-TRAL-uh-jee of fuh-LOW) is a rare condition caused by a combination of four heart defects that are present at birth (congenital). These defects, which affect the structure of the heart, cause oxygen-poor blood to flow out of the heart and to the rest of the body.

What are the complications of tetralogy of Fallot?

What are possible 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.

Is Tetralogy of Fallot coronary heart disease?

Background. An anomalous coronary artery is reported in 2% to 23% of patients with tetralogy of Fallot (TOF). Knowledge of coronary anatomy prior to corrective surgery is vital to avoid damage to vessels crossing the right ventricular outflow tract (RVOT).

Is tetralogy of Fallot fatal?

Tetralogy of Fallot (TOF) is a congenital heart defect that can be fatal if it’s left untreated. It’s also known as “tet.” The “tetra” in the name of the condition comes from the four problems associated with it. The condition is named after Dr. Etienne Fallot.

What is the most common congenital heart defect?

The most common type of heart defect is a ventricular septal defect (VSD).

What causes fetal heart defects?

It is caused by abnormal formation of the heart during growth in the womb. In most cases, when a baby is born with a congenital heart defect, there is no known reason for it. Some types of congenital heart defects can be linked to an abnormality in the number of a baby’s chromosomes.

How long can you live with tetralogy of Fallot?

Conclusions: The vast majority of the patients seemed to live normal lives 20–37 years after Tetralogy of Fallot repair. Late deaths were cardiac in origin, including sudden death from arrhythmias.

Why do patients with tetralogy of Fallot squat?

Squatting is a compensatory mechanism, of diagnostic significance, and highly typical of infants with tetralogy of Fallot. Squatting increases peripheral vascular resistance (PVR) and thus decreases the magnitude of the right-to-left shunt across the ventricular septal defect (VSD).

Can tetralogy of Fallot be cured?

Tetralogy of Fallot can cause problems if the heart is not fixed, however, corrective surgery performed in childhood for tetralogy of Fallot does not cure the condition. A surgical procedure called pulmonary valve replacement is usually performed, typically while under cardiopulmonary bypass.

What is hypoplastic left heart syndrome?

Hypoplastic left heart syndrome (HLHS) is a birth defect that affects normal blood flow through the heart. As the baby develops during pregnancy, the left side of the heart does not form correctly. Hypoplastic left heart syndrome is one type of congenital heart defect. Congenital means present at birth.

What causes right ventricular hypertrophy in tetralogy of Fallot?

The right ventricular hypertrophy occurs secondary to high pressure in the right ventricle (RV), created by the pulmonary stenosis and the large VSD. In the extreme situation, the right ventricular outflow tract is completely blocked off, in which case you have tetralogy of Fallot with pulmonary atresia.

Is tetralogy of Fallot a disability?

Congenital heart disease comes in many forms, with some presenting serious limitations for the patient and others being barely noticeable. If your type of congenital heart disease is so severe that you are unable to work, you may be able to get disability benefits from Social Security (SSDI or SSI).

What causes cyanosis in tetralogy of Fallot?

The cause of cyanosis is a lower than normal blood oxygen level. Patients with tetralogy of Fallot are at risk for cyanosis because the narrowing of blood flow to the lungs in combination with a VSD or hole allows blood in many instances to bypass the lungs and go directly up to the body.
