This progresses to heart failure which begins in the right ventricle and often leads to left heart failure and dilated cardiomyopathy.

The pulmonic stenosis is the major cause of the malformations, with the other associated malformations acting as compensatory mechanisms to the pulmonic stenosis. The primary symptom is low blood oxygen saturation with or without cyanosis from birth or developing in the first year of life. Tetralogy of Fallot results in low oxygenation of blood due to the mixing of oxygenated and deoxygenated blood in the left ventricle via the 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.

Retrieved 2 October The Sydney Morning Herald. Total repair of tetralogy of Fallot initially carried a high mortality risk, but this risk has gone down steadily over the years. From Wikipedia, the free encyclopedia.

This allows more blood flow to the lungs by decreasing shunting of deoxygenated blood from the right to left ventricle through the VSD. Retrieved 7 May Tftralogie heart defects Medical pentads.

Archived from the original on 4 October Archived from the original on January 30, These are acute hypoxia spells, characterized by shortness of breath, cyanosis, agitation, and tetraloogie of consciousness.

This increases systemic dr resistance and allows for a temporary reversal of the shunt. This redirected a large portion of the partially oxygenated blood leaving the heart for the body into the lungs, increasing flow through the pulmonary circuit, and greatly relieving symptoms in patients.

TOF is typically treated by open heart surgery in the first year of life.

There is anatomic variation between the hearts of individuals with tetralogy of Fallot. 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.
