Taussigand lab assistant Vivien Thomas at Johns Hopkins University developed a palliative surgical procedure, which involved forming a side to end anastomosis between the subclavian artery and the pulmonary artery. An aortic valve with biventricular connection, that is, it is situated above the ventricular septal defect and connected to both the right and the left ventricle.

The Blalock-Thomas-Taussig procedure, initially the only surgical treatment available for tetralogy of Fallot, was palliative but not curative.

Embryology studies show that it is a result of anterior malalignment of the aorticopulmonary septumresulting in the clinical combination of a VSD, pulmonary stenosis, and an overriding aorta. This then prevents ventricular wall closure, therefore VSD, and this increases the pressures on the right side, and so the R ventricle becomes bigger to handle the work.

The first total repair of tetralogy of Fallot was done by a team led by C. These are no longer used.

The right ventricle is more muscular than normal, causing a characteristic boot-shaped coeur-en-sabot appearance as seen by chest X-ray. Tet spells may be treated with beta-blockers such as propranololbut acute episodes require rapid intervention with morphine or intranasal fentanyl [26] to reduce ventilatory drive, a vasopressor such as phenylephrineor norepinephrine to increase systemic vascular resistance, and IV fluids for volume expansion.

It increases pressure on the left side of the heart, decreasing the right to left shunt thus decreasing the amount of deoxygenated blood entering the systemic circulation. A hole between the two bottom chambers ventricles of the heart. Journal page Archives Contents list.

Tetralogie de Fallot

Congenital heart defects are now diagnosed with echocardiographywhich is quick, involves no radiation, is very specific, and can be done prenatally. The RV enlargement and severe RV dysfunction increase risk tetralogiw ventricular tachycardia VT and sudden death in the long-term.


The Potts shunt [29] and the Waterston-Cooley shunt [30] [31] are other shunt procedures which were developed for the same purpose. This increases systemic vascular resistance and allows for a temporary reversal of the shunt. Archived from the original on 10 February All patients should have regular follow-up in a specialized grown-up congenital heart disease GUCH center to detect as soon as possible pathological signs of RV enlargement.

Retrieved 2 Dallot Episodes of bluish color to the skindifficulty breathing, heart murmurfinger clubbing [2]. TOF occurs in about 1 in 2, newborns. This progresses to heart failure which begins in the right ventricle and often leads to left heart failure and dilated dde. Access to the PDF text.

Mortality rate depends on the severity of the tetralogy of Fallot. Tetralogy of Fallot results in low oxygenation of blood dde to the mixing of oxygenated and deoxygenated blood in the left tetralogid via falloot ventricular septal defect VSD and preferential flow of the mixed blood from both ventricles through the aorta because of the obstruction to flow through the pulmonary valve.

Falllt more sophisticated techniques became available, chest x-ray was the definitive method of diagnosis. The clinical anatomy of tetralogy of Fallot. Congenital heart defects Medical pentads. In other projects Wikimedia Commons.

Ninety percent of people with total repair as babies develop a progressively leaky pulmonary valve later in life. Retrieved from ” https: Irregular heart ratepulmonary regurgitation [3]. Archived from the original on January 30, Right ventricular hypertrophy develops progressively from resistance to blood flow through the right ventricular outflow tract. Archived from the original on This may be initiated by any event leading to decreased oxygen saturation or that causes decreased systemic vascular resistance, which in turn leads to increased shunting through the ventricular septal defect.

The Sydney Morning Herald. Top of the page – Article Outline. The condition was initially thought untreatable until surgeon Alfred Blalockcardiologist Helen B. The baby may turn blue with breast feeding or crying. These are acute hypoxia spells, characterized by shortness of breath, cyanosis, falloot, and loss of consciousness.

The defect is centered around the most superior aspect of the ventricular septum the outlet septumand in the majority of cases is single and large. Access to the full text of this article requires a subscription. Its cause is thought to be due to tetfalogie or genetic factors or a combination.

Tetralogy of Fallot

Contact Help Who are we? From Wikipedia, the free encyclopedia. It can occur at the pulmonary valve valvular stenosis or just below the pulmonary valve infundibular stenosis.

It is associated with chromosome 22 deletions and DiGeorge syndrome. Diagram of a healthy heart and one with tetralogy of Fallot.

The primary symptom is low blood oxygen saturation with or without cyanosis from birth or developing in the first year of life. Repair of tetralogy of Fallot TOF exists for more than 40 years.
