What´s Complete Atrioventricular Canal Defect?

Good Essays
Introduction
Complete atrioventricular canal defect (CAVC) is a heart condition in which there is a large hole in the center of the heart and only one heart valve. Normally, the heart is divided into four chambers, and there is one valve on each side of the heart. The chambers on the right side of the heart receive blood from the body and pump it to the lungs where the blood gets oxygen. The chambers on the left side of the heart get the oxygen-rich blood from the lungs and pump it back out to the body. In CAVC, the blood in the chambers mix, and the heart valve may not close tightly. This makes the heart work much harder than normal.
CVAC is a problem that is present at birth (congenital heart defect). Children with CAVC usually start to have

    Imagine giving birth to a beautiful, healthy looking, baby girl and holding her in your arms for the first time. Now imagine a doctor telling you that this little miracle has a possible life threatening congenital heart defect. I can because this happened to me. My daughter suffers from three different congenital heart defects. According to the American Medical Association Family Medical Guide, about 8 out of every 1,000 children are born with heart abnormalities, or congenital heart defects.( AMAFMG p. 389) The 4 most recurring defects are Pulmonary Stenosis, Aortic Stenosis, Atrial Septal Defect and Ventricular Septal Defect.

    Congestive Cardiac Failure

    Congestive cardiac failure (CCF) is a progressive disease of the heart, which involves loss of pumping ability by the heart. Congestive cardiac failure occurs when the myocardium loses its ability to pump enough blood to meet the body’s metabolic needs and is generally accompanied by fluid accumulation in the body tissues, especially the lungs. The build–up of fluid affects the normal function of the heart, pulmonary circulation, blood pressure, the distribution of oxygen and nutrients, and electrolyte balance. Where oedema occurs in the body depends on the part of the heart that is affected by heart failure. Heart failure is almost always a chronic, long term condition, although sometimes it can develop suddenly. Pump failure usually occurs in a damaged left ventricle, but may also happen in the right ventricle. Usually, left ventricle heart failure develops first [Springhouse 2009 p38].…

    CHDs are present at birth and can affect the structure of a baby’s heart and the way it works. They can affect how blood flows through the heart and out to the rest of the body. CHDs can vary from mild (such as a small hole in the heart) to severe (such as missing or poorly formed parts of the heart).…

    There are two types of aortic valve diseases: regurgitation and stenosis. Aortic regurgitation is a condition in which blood flows backward from a weak or widened aortic valve into the heart’s left ventricle. Aortic Stenosis is a narrowing or blockage of the aortic valve. This happens with the valve leaflets become coated with deposits. Since this is makes the aortic valve smaller, the left ventricle has to work harder in order to get the same amount of blood through the small opening, over time, this extra work can weaken the heart. There are three mitral valve diseases: mitral valve prolapse, mitral regurgitation, and mitral stenosis. Mitral valve prolapse disease is where one or both of the valve flaps (cusps or leaflets) are enlarged and the flaps’ supporting muscles are too long; instead of closing evenly, the one or both of the flaps collapse or bulge into the left atrium. Mitral regurgitation is caused by earlier conditions that have weakened the heart, such as if a person has had a heart attack or had rheumatic fever as a child. Mitral stenosis is a narrowing or blockage of the mitral valve, the narrowed valve causes blood to back-up into the heart’s upper-left chamber instead of flowing into the lower-left chamber. Atrial septal defect, also known as ASD, is a “hole” in the wall that separates the top two chambers of the heart. Ventricular septal defect (VSD), is the opposite of ASD, it is a hole in the wall separating the two lower chambers of the heart. Tetralogy of fallot is a combination of four different problems: a hold between the lower chambers of the heart, the muscle surrounding the lower right chamber becomes overly thickened, an obstruction from the heart to the lungs, and when the aorta is over the hole in the lower chambers. These are a few of the heart conditions that a cardiothoracic surgeon…

    Heart failure occurs when the heart cannot pump enough blood for the body due to a weakened or damaged heart. The heart's pumping action moves oxygen-rich blood as it travels from the lungs to the left atrium, then on to the left ventricle, which pumps it to the rest of the body. The left ventricle supplies most of the heart's pumping power, so it's larger than the other chambers and essential for normal function. (American Heart Association). In left-sided or left ventricular heart failure, the left side of the heart must work harder to pump the same amount of blood. (American Heart Association). There are two types of left-sided heart failure: systolic heart failure and diastolic heart failure. Heart…

    In my Speech 1 class, the class delivered informative speeches based on the topics students chose. Also, the class was assigned to do a peer evaluation and the student I had to evaluate was Emily. The specific purpose statement for Emily’s speech was “To inform my audience about Atrioventricular Canal Defect”, and her method of organization seemed to be topical, which is a good when informing your audience about a health problem. Also, the main points of her speech included: what is atrioventricular canal defect, what are the symptoms, and what are the treatment options. Although Emily’s speech had many strengths and weakness when it came to the content and delivery of her speech, overall she did a great job.…

    Calcium in the diet of a teenager is absorbed in the small intestine and transferred to the intestinal capillaries. It diffuses into the bloodstream through the gastric vein into the hepatic vein and then through the common iliac vein into the superior/inferior vena cava that brings the blood into the right atrium of the heart. The sinoatrial node which is located in the right atrial wall, would send an electrical impulse through the heart, causing it to contract. This would then trigger the AV node (which is located between the septum between two atria) to contract as well. When the AV node contracts it sends an impulse through the AV bundle and into the purkinje fibers (which in return causes the entire heart to contract). After going through the right atrium, when the heart contracts it opens up the tricuspid valve, therefore pushing the calcium into the right ventricle. When the heart contracts again (SA node contracts again through AV bundle and purkinje fibers) it causes the pulmonary semilunar valve to open and enters the pulmonary trunk and pulmonary arteries which then brings the blood into the lungs. Then it goes through a systemic loop (the tissue capillaries of the lungs) , which takes the now oxygenated blood and returns to the heart via the pulmonary veins from the lungs. Then from the pulmonary veins the blood enters the left atrium (SA node will contract, causing AV node to contract, sending impulse through the AV bundle, ending at the purkinje fibers) and…

    Congenital heart diseases (CHDs) are the most common cause of all birth defects and account for nearly 30% of all major congenital anomalies leading to mortality in the first year of life. It occurs with an incidence of 1 per 100 live births. The major genetic causes for CHD include chromosomal disorders, single gene disorders, teratogenic disorders and multifactorial disorders. In one third of cases extracardiac anomalies are present, including urogenital anomalies.In this study we present a rare case of a 46,XY patient with CHD associated with ambiguous genitalia. Ambiguity of the external genitalia included: clitoris – like phallus (1.5 cm long), bifid scrotum, two palpable gonads were present in the bifid scrotum. Echocardiogram revealed…

    CVA (Cerebrovascular Accident), commonly known as a stroke, is a cardiovascular disease affecting the blood vessels that supply blood to the brain. A stroke occurs when a blood vessel that brings oxygen and nutrients to the brain bursts (hemorrhagic) or is clogged by a blood clot or some other mass (ischemic). When a vessel bursts or is clogged it deprives the brain of blood and oxygen it needs. If the brain does not receive the…

    It then continues as the right external iliac which comes together to the inferior vena cava, also known as the posterior vena cava. It is a vein that carries deoxygenated blood from the lower body to the heart. From there, the inferior vena cava leads to the right atrium of the heart. The right atrium is only one of the four hollow chambers of the heart. It receives blood from the superior vena cava and the inferior vena cava. The blood that comes through these veins is low in oxygen (“Right Atrium”, n.d.). After passing through the right atrium, we pass through the right atrioventricular (AV) valve, also called the tricuspid valve, and then we shall go through the right ventricle, lower right-hand chamber of the heart that pumps blood from the right atrium into the pulmonary arteries then to the lungs, to the pulmonary valve, or the pulmonary semilunar valve. The valves of the pulmonary semilunar valve opens when the right ventricle contracts. When the muscles…
