Cardiovascular Medicine Is One Of The Fastest Growing Area Of Study

Atrioventricular Canal Defect is an abnormality that causes the mixing of blood. There is a hole in center of heart where the wall between the upper and lower chambers meet. The tricuspid and mitral valves aren’t formed properly and one large valve crosses the defect. The defect lets oxygen rich blood pass to the heart’s right side and mix with deoxygenated blood, then go back to the lungs. Another abnormality is Atrial Septal Defect (ASD), where the walls of the upper chambers of the heart don’t close completely, causing a left to right movement of blood due to the higher pressure. The mixing of oxygenated and deoxygenated blood may cause the right atrium and ventricle to enlarge due to the higher volume of blood.

Over the past few years cardiovascular diseases have become the number one global cause of death. These diseases were first discovered 3,500 years ago with the Egyptians, and ever since then the causes have been pretty much the same. Although there are things that can be done to either increase or decrease the chances of getting heart disease. “Heart diseases describe a range of conditions that affect the heart” (Sheen 1). It can range from a myocardial infarction- a heart attack-, to a cerebral vascular disease, which is a disease of the blood vessels. Either way these diseases can impact the life of people in many negative aspects. Cardiovascular diseases have become the number one cause in global death due to the bad habits, diets, stress, and natural and chemical causes that the global population has.

2. The defect in Caleb’s heart allows blood to mix between the two ventricular chambers. Due to this defect would you expect the blood to move from left-to-right ventricle or right-to-left ventricle during systole? Explain your answer based on blood pressure and resistance in the heart and great vessels. It goes left to right during systole. The difference is normally, oxygen-poor (blue) blood returns to the right atrium from the body, travels to the right ventricle, and then is pumped into the lungs where it receives oxygen. Oxygen-rich (red) blood returns to the left atrium from the lungs, passes into the left ventricle, and then is pumped out to the body through the aorta. But when an infant has ventricular septal defect it still allows oxygen-rich (red) blood to pass from the left ventricle, through the opening in the septum, and then mix with oxygen-poor (blue) blood in the right ventricle. (ROCHESTER.EDU) but instead when systole occurs the blood gets mixed because of the septum therefore heart needs to pump harder to ensure that enough blood with oxygen reaches the body.

The medical field is rapidly growing with so many different careers to choose from. There are many different things that you could specialize in. There are so many opportunities in the medical field for you to grow and become something bigger. A very interesting field to go in is a pediatric nurse. This specific career path interests me because when my little brother was 5 years old he suddenly woke up one morning with his body completely swollen. We immediately rushed him to the hospital. While at the hospital they told us that he had Nephrotic Syndrome. His kidneys weren’t properly working and he was leaking excess protein in his urine. Since that day I knew exactly what I wanted to do. I wanted to help others, especially kids in their

Individuals with this disorder further acquire congenital heart defects. It specifically blocks off the natural blood flow from the lungs and right chamber of the heart and/or causes an anomalous gap in the barrier that divides the heart chambers in two. Another symptom of this disorder are the problems involved in the digestive system. People who have this syndrome are

In a normal human being the heart correctly functions by the blood first entering through the right atrium from the superior and inferior vena cava. This blood flow continues through the right atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary valve and into the pulmonary trunk. Blood is then distributed from the right and left pulmonary arteries to the lungs, where carbon dioxide is unloaded and oxygen is loaded into the blood. The blood is returned from the lungs to the left

A ventricular septal defect or VSD is a heart defect. It’s congenital, this means that a baby is born with it. It is an opening or hole in the dividing wall called the Septum, between the two lower chambers of the heart, right and left ventricles. Ventricular septal defects are the most common type of congenital heart defects. A VSD allows oxygen-rich blood to pass from the left ventricle through the opening in the septum. Then it mixes with oxygen-poor blood in the right ventricle. There are different types of ventricular septal defects, the type your child has depends on which part of the wall between the ventricles is involved. Also the size of the opening or hole varies. A ventricular septal defect may occur more often in some families, this is because of gene defects. But most of the time, the cause is unknown. Similarly to ventricular septal defect, an Atrial septal defect is a birth defect of the heart in which there is also a hole in the wall in the septum, but instead of dividing the lower chambers it divides the upper chambers of the heart (atria), here a hole can vary in size and may close on its own or may require surgery as well. An atrial septal defect is one type of congenital heart defect, in which also the baby is born with it.

Tetralogy of Fallot (ToF) is a rare, complex congenital heart defect. It occurs in about five out of every 10,000 babies. When babies are born with ToF, they have four different heart problems:

Cardiovascular Assessment: No visible pulsations, no heaves or lifts. Apical pulse present in the fifth intercostal space at the left midclavicular line. Auscultation of apical rate 62 beats per minute, normal rhythm regular S1 - S2 heart sounds present. Pulsations present when supine and disappear at a 45 degree angle position. Extremities are brown color without redness, cyanosis, lesions or varicosities bilaterally. Temperature warm bilaterally, Allen test was negative. Homan’s sign negative. Carotids: +2 and present bilaterally. Right Radial +2, left radial +1 , Right Brachial: +2

I. Description: Congestive Heart Failure is more of a syndrome than a disease. Heart failure may be classified according to the side of the heart affected, (left- or right-sided failure), or by the cardiac cycle involved, (systolic or diastolic dysfunction). (Schilling-McCann p. 176). The word "failure" refers to the heart's inability to pump enough blood to meet the body's metabolic needs. (Schilling-McCann p. 176). When the heart fails to deliver adequate blood supply edema may develop. (Cadwallader p. 1141). Where edema occurs depends on what side of the heart is failing.

During his wait for a transplant, cardiac stents were placed to keep vessels open and increase blood flow (Cardall, 2010). As a child, Cardall had the nickname of purple plum, due to being cyanotic; however, following the Fontan procedure his color was finally pink (Cardall, 2010). To redirect the blood flow one’s heart anatomy needs to be reconstructed and to have the Fontan procedure perform it is necessary to have two or three surgeries first (Porth & Matfin, 2009). A heart transplant is needed for those with progressing heart failure and there is no guarantee. The physiologic complications consist of arrhythmias, hemodynamics problems, and complications of cyanosis, endocarditis, residual lesion, additional surgery, exercise intolerance, and the need of non-cardiac surgery (Porth & Matfin, 2009).

Congenital heart diseases (CHDs) are the most prevalent of all birth defects and the leading cause of death in the first year of life, (1) with an annual prevalence ranging from six to twelve affected infants per 1,000 live births. (2)

Atrial Septal Defect(ASD) is a very large problem concerning the heart in its overall function. When the heart, being the core of the cardiovascular system, has issues; it effects the rest of the body as a result. The core of the problem resides in the atrial septum. Normally the heart is divided into four separate chambers. But a person with atrial septal defect has an atrial septum that allows the blood from the left side of the heart back into the right side. This results in increased pulmonary blood flow and diastolic overload of the right ventricle. By having this constant left-to-right shunt, it can alter the pulmonary vascular resistance leading to hypertension or even the reversal of the shunt itself.

Atrial Septal Defect is a common and interesting disorder. Atrial Septal Defect is mostly know as “a hole in the heart.” This disorder is birth defect. It can happen to male, female, adult, and kids. This disorder mostly happens to kids and infant. Atrial Septal Defect is when there is a hole in your heart that doesn’t allow oxygen to flow through. This can causes difficulty breathing, heart murmur, and e.t.c... There three different types of level. These level are called ostium secundum, ostium primum, and sinus venosus. The most severe level is ostium secundum which is the true atrial septal. Then is ostium primum, and last sinus venosus. This genetic disorder is typically diagnosed by noticing .symptoms.

Patent ductus arteriosus (PDA), one of the more common cardiac defects at birth, is the persistence of an opening between the pulmonary artery and the descending thoracic aorta. This opening is as a result of failure of the physiological fetus ductus arteriosus to close, which normally occurs soon after birth. This hole allows for oxygenated blood from the aorta to mix with oxygen-depleted blood from the pulmonary artery. As a consequence, significant strain is placed on the heart and pressure within the lungs’ arteries is dramatically increased.
