Blood Flow VelocityTwenty-six patients with tetralogy of Fallot and Potts anastomosis were evaluated 6 to 18 years after creation of the anastomosis. Thirteen of the 26 patients had evidence of moderate to sever

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...
Similar to many complex congenital heart diseases, tetralogy of Fallot is frequently diagnosed during fetal life (figure 2). For those with severely obstructed pulmonary blood flow, fetal diagnosis allows better planning of perinatal management and facilitates early prostaglandin therapy to maintain ductal...
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...
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...
Tetralogy of Fallot (TOF) is one of the most common congenital heart disorders (CHDs). This condition is classified as a cyanotic heart disorder, because tetralogy of Fallot results in an inadequate flow of blood to the lungs for oxygenation (right-to-le
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...
Background Despite widespread uses of ketamine, the clinical studies determining its effect on pulmonary blood flow in children with tetralogy of Fallot (TOF) are lacking. Furthermore, the quantification of pulmonary blood flow is not possible in these patients, because pulmonary artery catheter is ...
