The most common multiple defect is tetralogy of Fallot, in which four heart abnormalities occur together: a ventriculoseptal defect, pulmonary stenosis, a displaced aorta, and a thickened right ventricle.
a blood vessel in a fetus that bypasses pulmonary circulation by connecting the pulmonary artery directly to the ascending aorta; normally closes at birth
PATENT DUCTUS ARTERIOSUS
The ductus arteriosus is a blood vessel that connects the pulmonary artery to the aorta in the fetus so that blood bypasses the lungs.
a semilunar valve between the right ventricle and the pulmonary artery; prevents blood from flowing from the artery back into the heart
In this condition, the pulmonary valve, which opens to allow blood to flow from the right ventricle into the pulmonary artery, is narrowed so that blood flow is restricted.
French physician who described cardiac anomalies including Fallot's tetralogy (1850-1911)
The most common multiple defect is tetralogy of Fallot, in which four heart abnormalities occur together: a ventriculoseptal defect, pulmonary stenosis, a displaced aorta, and a thickened right ventricle.
an integer that is a multiple of two or more other integers
The most common multiple defect is tetralogy of Fallot, in which four heart abnormalities occur together: a ventriculoseptal defect, pulmonary stenosis, a displaced aorta, and a thickened right ventricle.
the chamber on the right side of the heart that receives venous blood from the right atrium and pumps it into the pulmonary trunk
In this condition, the pulmonary valve, which opens to allow blood to flow from the right ventricle into the pulmonary artery, is narrowed so that blood flow is restricted.
Children may be susceptible to chest infections and are at increased risk of infection of the lining of the heart (see Infective endocarditis), especially after surgery or dental treatment.
a chamber of the heart that receives blood from an atrium
In this condition, the pulmonary valve, which opens to allow blood to flow from the right ventricle into the pulmonary artery, is narrowed so that blood flow is restricted.
a series of four related works (plays or operas or novels)
The most common multiple defect is tetralogy of Fallot, in which four heart abnormalities occur together: a ventriculoseptal defect, pulmonary stenosis, a displaced aorta, and a thickened right ventricle.
a dividing partition between two tissues or cavities
In this defect, there is a hole in the septum (the inner wall that divides the heart) either between the two lower chambers (ventriculoseptal defect) or alternatively between the two upper chambers (atrioseptal defect).
yielding readily to or capable of undergoing a process
Children may be susceptible to chest infections and are at increased risk of infection of the lining of the heart (see Infective endocarditis), especially after surgery or dental treatment.
