How is subaortic stenosis treated?
The subaortic stenosis is repaired by opening the aorta just above the aortic valve. The subaortic membrane can be seen through the valve. The membrane can then be cut out, leaving the left ventricle’s outflow tract open and smooth.
How serious is subaortic stenosis?
As the obstruction worsens, some patients may have chest pain or pass out during exercise or exertion. Others may develop fast heart beats or, rarely, congestive heart failure as fluid builds up in the heart. Patients with severe or untreated subaortic stenosis may be at risk for sudden cardiac death.
What is Subvalvular?
Medical Definition of subvalvular : situated or occurring below a valve (as a semilunar valve) subvalvular stenosis.
What can aortic stenosis lead to?
Aortic valve stenosis may lead to heart failure. Heart failure signs and symptoms include fatigue, shortness of breath, and swollen ankles and feet.
What does stenosis mean?
Stenosis, which means narrowing, can cause pressure on your spinal cord or the nerves that go from your spinal cord to your muscles. Spinal stenosis can happen in any part of your spine but is most common in the lower back. This part of your spine is called your lumbar area.
Is subaortic stenosis a heart disease?
Subaortic stenosis is a congenital heart defect, so there are no known risk factors for it. However, physical stress, including exercise and pregnancy, can cause symptoms to develop if the condition is untreated or if treatments aren’t successful.
How common is subaortic stenosis?
Excerpt. Subvalvular aortic stenosis (SAS), also called subaortic stenosis, is a rare disorder seen in infants. In most cases, there is a membrane (usually muscular) just below the aortic valve which causes a fixed obstruction to the blood flow across the left ventricular outflow tract.
What causes Subvalvular aortic stenosis?
Subvalvular aortic stenosis causes Subvalvular aortic stenosis is a congenital heart defect that occurs during fetal development. The precise cause is unknown, but genetics may play a role. Subaortic stenosis has also been associated with several congenital syndromes.
What is Infundibular stenosis?
First described by Elliotson, infundibular pulmonary stenosis (IPS) refers to obstruction of outflow from the right ventricle (RV) within the body of the RV, as opposed to obstruction at the pulmonary valve, pulmonary artery (PA), or its branches.
Is spinal stenosis serious?
Spinal stenosis is a condition that results in the narrowing of the spinal column, often accompanied by painful, debilitating compression of the spinal cord as well as nerve roots. For some people, the pain can be so severe it is incapacitating, making even everyday activities nearly impossible.
What is subvalvular aortic stenosis?
Subvalvular aortic stenosis, or subaortic stenosis, consists of a heterogeneous group of abnormalities, several of which are associated with other types of cardiac malformation.
Is membranous subaortic stenosis associated with patent ductus arteriosus?
branous subaortic stenosis but is in keeping with the predominance of female patients with patent ductus arteriosus. The etiology of discrete membranous subaortic stenosis in general and in association with patent ductus arteriosus is unclear. We wonder whether
Which imaging findings are characteristic of discrete membranous subaortic stenosis (MS)?
Clinical, hemodynamic, angiographic and echocardiographic findings in a patient with discrete membranous subaortic stenosis are presented. Echocardiography revealed evidence of a normal mitral valve and abnormal movement of the aortic valve with poor motion and fluttering of the anterior cusp.
What is subsubaortic stenosis?
Subaortic stenosis is a narrowing below the aortic valve (Fig. 5-14). There are two commonly described subtypes: a fibromuscular ridge and a tunnel-type obstruction. Color flow Doppler imaging detects turbulence whereas pulsed wave Doppler imaging helps to localize the origin of acceleration.
