This page from Great Ormond Street Hospital (GOSH) explains tracheal stenosis, how it can be treated and what to expect when a child has treatment. This page mainly concentrates on the ‘long segment’ type of tracheal stenosis and its treatment.
Pulmonary stenosis is a narrowing of the valve between the right pumping chamber (right ventricle) and the large blood vessel that carries blood to the lungs to pick up oxygen (pulmonary artery).
The ductus arteriosus is a blood vessel that connects the pulmonary artery (main vessel supplying the blood to the lungs) to the aorta (main vessel supplying the blood to the body). This connection is present in all babies in the womb, but should close shortly after birth. In some babies, especially in those born prematurely, this vessel may remain open. This is called a patent or persistent ductus arteriosus.
Hypoplastic left heart syndrome is a condition where the left lower pumping chamber (left ventricle) of the heart does not develop properly so is much smaller than usual. The mitral valve between the left ventricle and the upper left filling chamber (left atrium) is often closed or very small.
Functionally univentricular heart is the term used to describe a number of congenital heart defects whose common feature is the lack of two fully-developed pumping chambers (ventricles).
Truncus arteriosus is a condition where there is just one large blood vessel instead of two separate vessels leaving the pumping chambers (ventricles) of the heart.
