tetralogy of FallothemodynamicsFrom the hemodynamic point of view, TOF has two basic components viz., a large ventricular septal defect (VSD) and RVOT obstruction. Since the VSD is nonrestrictive, both right and left ventricle have the same systolic pressure. [...] the pulmonary blood flow ...

This patient was operated upon for a cardiac defect, when she was 3 years old. The most common congenital cyanotic heart disease that is associated with survival until adolescence and sometimes even into adulthood is tetralogy of Fallot. Therefore, in all probability, this patient was operated upo...
The anatomy of tetralogy of Fallot (TOF) was first described by Stetson in 1671, and it was more than a century before Fallot published in 1888.1 The first management strategies involved establishing a reliable source of pulmonary blood flow with palliative procedures, such as the Blalock-Taussig...
A hallmark of tetralogy of fallot is the deficiency of oxygenated blood being pumped to the heart from the lungs and from the heart into the aorta to the rest of the body. To better understand how this abnormality can have a negative effect on patients it helps to visualize how the heart...
As obstruction in RV outflow tract increases, more blood is shunted through the VSD to the left side of the heart to cause more cyanosis (see fig 23C). Increases in resistance to flow in the general arteries of the body causes less shunting, and decreases cause more shunting to the left...
One-hundred and twenty-two patients underwent intracardiac repair for tetralogy of Fallot between the ages of four and twenty-one. Isolated infundibular stenosis was seen in 63.6 per cent combined infundibular and valvular stenosis in 17.3 per cent, diffuse hypoplasia of outflow tract and main ...
This displacement also causes pulmonary stenosis by blocking flow to the pulmonary artery; the result is increased pressure on the right side of the heart and right ventricular hypertrophy. 目前认为法洛四联症产生的原因是由于胚胎时期漏斗部发育不良及漏斗部间隔向前及向上移位所致,这个移位导致了室间隔缺损...
or uncommonly right heart failure. Sudden death before 1 year of age is common from hypoxia, hyperviscosity, or cardiac arrhythmias. The most common cardiac auscultatory finding in animals with tetralogy of Fallot is a left basilar, systolic ejection murmur produced by blood flow through the sten...
tetralogy of Fallot a congenital heart defect that combines four structural anomalies: obstruction to pulmonary flow; ventricular septal defect (abnormal opening between the right and left ventricles); dextroposition of the aorta (aortic opening overriding the septum and receiving blood from both ventricl...
