Tetralogy of Fallot - Tetralogía de Fallot

Four abnormalities that make the blood circulate throughout the body without enough oxygen

Narrowing of the pulmonary valve, the medical term for this pathology is pulmonary infundibular stenosis

Thickening of the right ventricular wall, the medical term for this condition is right ventricular hypertrophy.

Displacement of the aorta over the ventricular septal defect, the medical term for this condition is overriding aorta.

Opening in the ventricular septum between the left and right ventricles, the medical term for this condition is ventricular septal defect.

Cuatro anomalías que hacen que la sangre circule sin suficiente oxigeno por el cuerpo

Estrechez de la válvula pulmonar, el termino medico para esta patología es estenosis pulmonar infundibular

Engrosamiento de la pared ventricular derecha, el termino medico para esta patología es hipertrofia ventricular derecha.

Desplazamiento de la aorta sobre el defecto del tabique ventricular, el termino medico para esta patología es dextraposición de la aorta o aorta cabalgante.

Abertura del defecto del tabique ventricular entre los ventrículos izquierdo y derecho, el termino medico para esta patología es comunicación interventricular.

Tetralogy of Fallot

Tetralogy of Fallot is a congenital heart defect which usually involves four anatomical abnormalities of the heart. It is the most common cause of blue baby syndrome. It results in low oxygenation of blood due to the mixing of oxygenated and deoxygenated blood in the left ventricle via the ventricular septal defect, and preferential flow of the mixed blood through the overriding aorta because of the obstruction of the pulmonary stenosis. This is known as a right-to-left shunt.

This condition is characterized by noticeable cyanosis, fatigue, a heart murmur, delayed growth and physical development, dyspnea on exertion, and finger clubbing. It is common to see these children frequently squatting, this is a mechanism to alleviate the hipoxigenación that affects them, due to the increase in systemic vascular resistance.

Tetralogía de Fallot

La Tetralogía de Fallot es un defecto cardíaco congénito que generalmente implica cuatro anormalidades anatómicas del corazón. Es la causa más común del síndrome del bebé azul. Es el resultado de baja oxigenación de la sangre debido a la mezcla de sangre oxigenada y desoxigenada en el ventrículo izquierdo a través de la comunicación interventricular, y el flujo preferencial de la sangre mixta a través de la aorta cabalgante debido a la obstrucción de la estenosis pulmonar. Esto se conoce como un cortocircuito derecha-izquierda.

Esta patología es caracterizada por una marcada cianosis, fatigabilidad, soplos cardiacos, retraso en el crecimiento y el desarrollo físico, disnea de esfuerzo y dedos en palillo de tambor. Es común ver a estos niños acuclillarse frecuentemente, esto es un mecanismo para aliviar la hipoxigenación que los afecta, dado por el aumento de las resistencias vasculares sistémicas.
