What is the usual direction of blood flow across a Ventricular Septal Defect?
the world may never know
Can people with supra ventricular tachycardia SVT donate blood?
No...you should not donate blood if you are tachycardic. Most blood banks will not allow you to donate blood if you heart rate is over 100. Some people with SVT can have a seizure if they donate blood. This is a question you need to have answered by your cardiologist.
What do right-side elevated oxygen levels indicate in a cardiac catheterization?
Right-side elevated oxygen levels in a cardiac catheterization may suggest the presence of a congenital heart defect such as an atrial septal defect or a ventricular septal defect. It can cause blood to be shunted from the left side of the heart to the right side, leading to higher oxygen levels in the right side of the heart.
How do you explain about the VSD?
Ventricular septal defect (VSD) is a congenital heart defect where there is an abnormal opening in the wall that separates the heart's lower chambers (ventricles). This opening can cause oxygen-rich and oxygen-poor blood to mix, leading to increased workload on the heart. Symptoms can vary depending on the size of the defect, but treatment may involve monitoring, medications, or surgery to repair the defect.
Why tetralogy of fallot babies go blue after being born?
Their blue skin, a condition called cyanosis, comes from the Ventricular Septal defect. This is a whole in the wall of the left and right ventricles which allows deoxygenated, blue, blood to travel throughout the rest of the body.
Anatomy and physiology of tetralogy of fallot?
Tetralogy of Fallot is a congenital heart defect characterized by four specific heart defects: ventricular septal defect, overriding aorta, pulmonary stenosis, and right ventricular hypertrophy. This condition results in decreased oxygen levels in the blood due to mixing of oxygen-rich and oxygen-poor blood, leading to symptoms such as cyanosis (blue discoloration of the skin). Surgical correction is typically necessary to improve blood flow and oxygenation.
Surgical management of tetralogy of fallot?
There are two common surgical procedures for treatment of tetralogy of fallot: the Blalock-Tausigg Shunt and a patch. The Blalock-Tausigg Shunt is used to direct more blood flow to the lungs, in order to relieve cyanosis, but it is only meant as a temporary treatment until the patient is stable enough to undergo further treatment. A patch is used, during open heart surgery, to close a ventricular septal defect or atrial septal defect.
How does ASD affect the heart?
Atrial Septal Defect, also known as ASD, affects the heart by allowing oxygen rich blood into the chamber with oxygen poor blood. The septum between the two has a defect allowing this to happen, therefore allowing blood with a poor concentration of blood to travel to the lungs.
What are the symptoms of a ventricular septal defect?
Ventricular Septal Defect SymptomsSmall holes in the ventricular septumusually produce no symptoms but are often recognized by the child's health care provider when a loudheart murmur along the left side of the lowerbreast bone or sternum is heard. Large holes typically produce symptoms 1-6 months after an infant's birth. The left ventricle begins to fail, producing the following symptoms:Fast breathingSweatingPallorVery fast heartbeatsDecreased feedingPoor weight gainWhen a ventricular septal defect is not detected early in life, it can cause more severe problems and more severe symptoms as time goes on. The biggest concern is development of high pressure in the lungs (pulmonary hypertension). If the ventricular septal defect is not surgically closed, irreversible pulmonary hypertension can develop, and the child is no longer operable and has a poor prognosis. The following are typical symptoms of pulmonary hypertension:FaintingShortness of breathChest painBluish discoloration of the skin (cyanosis)The skin turns faintly bluish when the tissues are not receiving quite enough oxygen. This condition is often termed "hypoxemia" or "hypoxia."
What causes atrial septal defect?
Atrial septal defect is typically caused by a failure of the septum between the upper chambers of the heart (atria) to close properly during fetal development. This can lead to a hole in the septum, allowing blood to flow between the two atria. In some cases, the cause may be genetic or related to other factors such as maternal exposure to certain substances during pregnancy.
What conditions can be revealed by cardiac catheterization?
enlargement of the left ventricle; ventricular aneurysms (abnormal dilation of a blood vessel); narrowing of the aortic valve; insufficiency of the aortic or mitral valve; and septal defects
What causes a heart murmur and how does it sound?
Some causes of heart murmurs can include a congenital defect in a heart valve, a hole in the wall of the heart, endocarditis, and many other medical conditions. Some symptoms of a heart murmur are shortness of breath, fainting, and pain in the chest area.
