1)In a child with ASD,blood can travel across the hole from the left atrium to the right atrium and out into the lung arteries.If the ASD is large,the extra blood being pumped into the lung arteries makes the heart and lungs work harder and the lung arteries can become gradually damaged.In children with a large ASD,the main risk is the to the blood vessels in the lungs because more blood than normal is being pumped there.over time,this may cause permenant damage to lung blood vessels.
2)In a child with VSD,blood can travel across the hole from the left vetricle to the right ventricle and out into the lung arteries.If the VSD is large,high pressure may occur in the blood vessels in the lungs because more blood than normal is being pumped there.
3)The oxygenated blood and deoxygenated blood will mix.this will then can transported around the body.The child with Large ASD may not be able to do very strenous avtivity

1) Effects of ASD
1.Right heart enlargement that leads to heart failure.
2.Blood flows reverse,that is blood flows from right to left,instead of left to right,which will lead to pulmonary hypertension and oxygen levels of blood decreases.
3.Oxygenated blood and Deoxygenated blood mix together,some blood with oxygen return to lungs,causing the heart to be inefficient to transport oxygenated blood around the body,at the same time, causes the blood with no oxygen to spread around the body without oxygen.
3)A child with ASD would be different from a normal child as the child may experience deficiency of oxygen unlike other normal children,which causes rapid breathing during physical activity,easy tiredness and poor growth,frequently, these special children may also have lung infections.
2)Effects of VSD
1. Easily tired, breathing fast or incapable of breathing and poor diet,which leads to stagnant weight for young children.
2)Abnormal heart rhythms and valve problems

The left side of the heart only pumps blood to the body, while the right side of the heart only pumps blood to the lungs. But for a patient with ASD, blood can travel across the hole from the left atrium to the right atrium and out into the lung arteries.If the ASD is large, the extra blood being pumped into the lung arteries makes the heart and lungs work harder, which may result in the gradual damage of the lungs.

The heart functions as stated in the above, In a child with VSD, blood can travel across the hole from the left ventricle to the right ventricle and out into the lung arteries. If the VSD is large, the extra blood being pumped into the lung arteries makes the heart and lungs work harder and the lungs can become congested.

For a child with minor ASD, he can carry on with his daily activities with not much risk involved. But for those with a more major ASD, the child may have to limit himself.

The left atrium assist the left side of the heart to pump oxygenated blood around the body. The right atrium assist the right side of the heart to pump deoxygenated blood to the lungs. But if a child is affected with atrial septal defect(ASD) the oxygenated blood on the left and deoxygenated blood on the right will mixe this thus this may affect the amonut of oxygen pump around the body.
As the heart system is stated, if a child is affected with venticular septal defect(VSD) the affect would be the same as ASD.
A child would feel more tired easily than normal due to the lack of oxygen pump aroung the body. This will thus affect how active the child can be.

1]effects of ASD
-the hole in the heart will cause the deoxygenated blood in right atrium to mix with the oxygenated blood in left atrium,so when blood is pump to any part of the body ,there will be a inefficient transfer of oxygen,this will cause the need for the heart to pump faster.
2]effects of VSD
the hole in the heart will cause the deoxygenated blood in right ventricle to mix with the oxygenated blood in left ventricle,so when blood is pump to any part of the body ,there will be a inefficient transfer of oxygen,this will cause the need for the heart to pump faster.
3]child with asd v normal child
-child with asd will have a faster heart beat than normal child
-child with asd will have a more irregular heart beat than a normal child.

1)Effects of ASD
-The opening in the tissue of the upper chamber of the heart allows oxygenated blood to leak into the deoxygenated blood chambers.
-Thus causing inefficient transport of oxygen around the body.
-There are also may be heart rhythm disturbances.
-There is high Chances for strokes to occur also.
2)Effects of VSD
-The opening in the tissues of the lower chambers of the heart causes oxygenated blood to mix with deoxygenated blood.
-Thus causing inefficient transport of oxygen around the body as the heart needs to pump faster to get the required amount of oxygen.
-Due to this if the VSD is large,the extra blood being pumped into the lung arteries makes the heart and the lungs to work harder and the lungs could also become congested due to this.
3)ASD vs NORMAL
-A child with ASD will experience more challenge and will be tired out more easily when taking part in a strenuous activity. As when it comes to a normal child as the heart of a child with ASD can transport little oxygen at a time compared to a heart of a normal child who can transport more oxygen at a time.

1) When a child has ASD, blood from the left side and the right side of the atrium mixes which cause the heart to not work at an efficient level. It causes the right heart to enlarge which leads to right heart failure. It also causes heart rhythm disturbances, including atrial fibrillation or atrial flutter and a leaking tricuspid and mitral valves as a result of enlargement of the heart

2) Normally, the left side of the heart only pumps blood to the body, and the heart's right side only pumps blood to the lungs. In a child with VSD, blood can travel across the hole from the left ventricle to the right ventricle and out into the lung arteries. If the VSD is large, the extra blood being pumped into the lung arteries makes the heart and lungs work harder and the lungs can become congested.

3) A child with ASD would not be able to do vigorous activities because the heart does not work efficiently as deoxygenated blood mixes with oxygenated blood which causes the heart to do extra work to transport oxygen throughout the body.

1) When a child is born with ASD, oxygenated blood from the left side of the heart and deoxygenated blood from the right side of the heart would mix and the heart generally would not work at its most effiecient level.

2) Blood from the left side of the heart (oxygenated) would be forced into the right side of the heart. It is pumped back to the lungs even though it is already oxygenated. The heart would then be caused to work harder to pump more blood.

3)A child born with ASD would have a faster and irregular heartbeat compared to a normal child

1) the left side of the heart pumps oxygenated blood into the body while the right side of the heart pumps deoxygenated blood into the lungs to convert them into oxygenated blood.The hole at the upper chambers of the heart will cause the deoxygenated blood to travel into the left atrium and mixing with the oxygenated blood.The extra blood pumped into the lungs arteries will make the heart and lungs work harder and faster as the amount of oxygenated blood is lesser and hence the lungs have to work harder to convert the deoxygenated blood into oxygenated blood while the heart work harder by pumping more blood so that the body can receive the oxygenated blood at a faster rate.

2)The left side of the heart pumps oxygenated blood into the body while right side of heart pumps deoxygenated blood into the lungs. Due to the hole between the the left ventricle and right ventricle, the blood will travel from the the left ventricle to the right. Hence the heart and lungs will work harder and become congested.

3) Child with asd will have a faster heart rate due to the faster rate of pumping of the heart to allow oxygenated blood to travel to the rest of the body while normal child will have a normal heart rate as they have a stable amount of oxygenated blood traveling around the body hence the heart do not need to work very hard and hence slower heart rate than child with asd.

1) Effects of ASD would be that the concentration of oxygen in the left and right atrium would equalized, which is bad as lesser amount of oxygen is transported to the rest of the body. Forcing the heart to pump faster.

2)Effects of VSD would also be the same as ASD, the concentration of oxygen in the left and right ventricle would equalize and lesser amount of oxygen is transported to the rest of the body. Forcing the heart to pump faster.

2) The child with ASD would be more exhausted more frequently than a normal child. This is because, the amount of oxygen needed would be the same but due to the lesser amount of oxygen transported, the heart will pump faster to meet the required amount of oxygen needed. So more energy would be used.

3)A hole in the septum between the heart's two upper chambers is called an atrial septal defect. Which means a hole between the left and right atriums of the heart. It may cause Right heart enlargement (leading to right heart failure) Heart rhythm disturbances, or even stroke as not enough oxygenated blood is transported out of the heart to all other parts of the body.

2) A hole in the septum between the heart's two lower chambers is called a ventricular septal defect(VSD) and VSD allows blood to pass from the left side of the heart to the right side. If this hole is too big, blood will travel from the left side of the heart to the right side of the heart, into the lungs, causing high blood pressure which may lead to permanant damage in the lung's blood vessels in the future.

3) A child with ASD, will not be able to pump as much blood that is oxygenated to all other parts of his body, thus he might feel more fatigued and tired, compared to a normal and healthy child who is able to pump more oxygenated blood

The effects of ASD and VSD - Aaron

2016-07-27 23:09:53 UTC

ASD is when there is a hole between the left and right atrium. This causes deoxygenated blood in the right atrium to flow into the left atrium and vice versa. Because of this, the concentration of oxygen in the blood that it pumped into the aorta throughout the body is lower than normal,

1)The effects of ASD could cause the right side of the heart to enlarge, this might lead to heart failure. The enlargement of the heart may also cause the tricuspid and bicuspid to leak. ASD would allow the blood from both atrium to mix, causing oxygen levels to decrease and hence the heart would pump harder and faster. It could also affect the heart rhythm or cause the patient to get stroke.

2)The effects of VSD are the same as the effects of ASD
3)A child with ASD could have symptoms such as poor appetite , poor growth , fatigue ,shortness of breath and lung problems and infections like pneumonia.

1. Usually, the right atrium of the heart pumps blood that is deoxygenated to the lungs, whereas the left atrium of the heart pumps oxygenated blood to the blood. Thus, when one is diagnosed with ASD, the blood from the right atrium of heart is mixed with the left atrium of heart, it causes the heart
to be working not as efficient. The effects of ASD would be the enlargement of right heart that may have the risk of having right heart failure, heart rhythm disturbances, stroke and pulmonary hypertension which means the high blood pressure in the arteries that supply blood to the lungs and lastly the leaking of tricuspid and bicuspid valves.

2. The effects of VSD are similar to the effects of ASD. When a person is diagnosed with VSD, blood can travel from the left ventricle to the right ventricle and to the lung arteries. Hence when a person has a VSD that is big, the excess blood that is pumped into the lung arteries caused both the lungs and the heart to work harder, and
subsequently the lungs can also become congested.

3. There will be differences between a child with ASD and a normal child. Differences will be that the child with ASD will have difficulties in breathing and the heart will also not be able to pump as much blood that is oxygenated to other parts of the body. The child with ASD will also feel more tired when doing physical activities compared to a normal child.

1)Effects of ASD
The opening in the tissue of the upper chamber of the heart allows oxygenated blood to be mixed with the deoxygenated blood of the other chambers.Thus causing inefficient transport of oxygen around the body which may lead to heart rhythm disturbances and strokes.
2)Effects of VSD
-The opening in the tissues of the lower chambers of the heart causes oxygenated blood to mix with deoxygenated blood.
Hence, resulting in inefficient transport of oxygen to all parts of the body as the heart needs to pump faster to ensure there is sufficient oxygen transported to all parts of the body.
3)Differences between a child with ASD and a normal child.
A child with ASD will face challenges such as being easily tired out when taking part in a strenuous activity. He or she will also be of higher risk of breathing problems and asthma due to them being able to transport lesser oxygen. Meanwhile, when it comes to a normal child the heart will be able to pump sufficient oxygenated blood to all parts of the body. Thus, being able to conduct activities without feeling fatigue easily.

Effect of ASD:
ASD causes a hole in between the left atrium and right atrium which can allow the mixing of oxygenated blood from the pulmonary veins with the deoxygenated blood from the pulmonary artery. This can lead to the ineffectiveness of the circulation.

Effect of VSD:
VSD causes a hole in between the left ventricle and right ventricle that can allow the mixing of oxygenated and deoxygenated blood as well. It also lowers the effectiveness of our circulation.

How would a child with ASD be different from a normal child???
The child with ASD may be harder for respiration and he/she may gets tired easily. In addiction, he/she may has high blood pressure.

1. oxygenated blood can flow from the left atrium to mix with the deoxygenated blood in the right atrium of the heart.This can lead to lower oxygen levels in the arterial blood that supplies the brain, organs, and tissues in the body
2. VSD caused a hole in the wall separate the left and right ventricles,so blood can travel across the hole from the left ventricle to the right ventricle.If the VSD is large, the extra blood being pumped into the lung arteries makes the heart and lungs need to work extra hard and there will be an unnatural accumulation of blood in the lungs.
3. -a child with ASD may have shortness of breath when exercising, so they cannot do outdoor activities like normal child
-they may have frequent lung infections and need to go hospital very often，making them cannot go to school like normal children
-easier to get stroke as their blood have lesser concentration of oxygen

1. Those under the effects of ASD will show that the dividing wall that separates the left atrium and right atrium is defective or absent, this allows the deoxygenated blood in the right atrium to mix with the oxygenated blood in the left atrium, affecting the concentration of oxygen that is transported around the body, as a result, the heart requires to pump blood faster in order to compensate for the decrease in oxygen being transported.
2. Those under the effects of VSD have a hole in the wall and the oxygenated blood in the right ventricle mixes with the deoxygenated blood in the left ventricle, this leads to more blood entering the lungs, increasing the pressure in the capillaries in the lungs.
3. blood will shunt from the left atrium to the right atrium. This extra blood from the left atrium may cause a volume overload of both the right atrium and the right ventricle. If untreated, this condition can result in enlargement of the right side of the heart and ultimately heart failure.
