    Aortic Surgeon Research Paper

    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…

    Congenital Heart Defects in Children

    The most common form of congenital defect is Ventricular Septal Defect or VSD. A VSD is an opening of the septum that separates the left and right side of the heart, or commonly known as a hole in the heart. This is found between the ventricles. The severity of the symptoms vary based on the size of the hole. Smaller defects often don’t present any symptoms, where patients with larger defects will often have a distinct heart murmur. The Atrial Septal Defect, or ASD, is a defect or hole in the wall between the atria, which is the two upper chambers of the heart. Children that suffer from atrial defects typically don’t show any symptoms. These defects generally do not require any intervention and close on their own over time. Two other types of defects are the Pulmonary and Aortic Stenosis’s . A Pulmonary Stenosis is the narrowing of the heart valve that normally allows blood flow from the heart to the lungs. The Aortic Stenosis is the narrowing of the heart valve that lets the blood flow from the heart into the main artery of the body, or aorta, and out to the rest of the body. Both types require the heart to work overtime to provide the necessary blood flow that the body needs.…

    Psy 201 Week 2 Developmental Interview Questions

    She used mostly concrete, observable characteristics. The textbook indicates that children do not talk about self worth until age 8, but that their behavior may indicate self-esteem. I feel that Suzy has developed self-esteem and demonstrates self-esteem related issues already with regards to her peer group. A young child's self concept extends to what makes her happy or sad. Social psychologists such as Jean Piaget believe that a child’s concept of self evolves as he gets older. The ability to reason and understand morals, or to differentiate right from wrong, grows as he understands more fully that he is a separate individual from his parents and the rest of the world. Parents can aid in their children's moral development by engaging in age-appropriate activities with their children and basing moral teachings on their children's ability to understand. Preoperational children often have relatively high self-esteem because early self-concepts are based on easily defined and observed variables, and because many young children are given lots of encouragement. Young children are also generally optimistic that they have the ability to learn a new skill, succeed, and finish a task if they keep trying. Self-esteem comes from several sources, such as school ability, athletic ability, friendships, relationships with caregivers, and other helping and playing…
