Left-handedness

SINGLE VENTRICLE DEFECTS? Single ventricle defects are heart problems that you were born with (congenital heart defects). Normally the heart has two pumping chambers. These are the right and left ventricles. The right ventricle pumps blood to the lungs to get oxygen. After blood returns from the lungs, the left ventricle pumps it out to the body. Single ventricle defects come in many forms. They can involve one or more valves in your heart and a ventricle that does not pump effectively In…

recently invented to support one of the functions of the heart is the Left Ventricle Assist Device. What is Left…

Introduction Mitral valve regurgitation, also called mitral regurgitation, is a condition in which blood leaks from the mitral valve in the heart. The mitral valve is located between the upper left chamber of the heart (left atrium) and the lower left chamber of the heart (left ventricle). Normally, this valve opens when the atrium pumps blood into the ventricle, and it closes when the ventricle pumps blood out to the body. Mitral valve regurgitation happens when the mitral valve does not close…

undergoes adjustments in the first trimester to become the heart. The heart is made up of four chambers: the right atrium, the left atrium, the right ventricle, and the left ventricle. There are two atrioventricular valves: the tricuspid valve in the right side and the mitral valve in the left side. There are also the pulmonary and aortic valves that originate from the right and the left ventricles. The heart is located in the mediastinum. During embryonic development, oxygenated blood from the…

of major and minor cardiac criteria. (A minimum of three major criteria or at one major and three minor criteria). • Major criteria include advanced atrioventricular block, basal thinning of the interventricular septum, cardiac gallium uptake, and left ventricular ejection fraction 40 mg/day of prednisone) compared with those treated with a low dose (35 percent and/or lack of heart failure: • In patients with cardiac sarcoidosis with an inducible ventricular arrhythmia at electrophysiologic…

Any sort of symptoms depends on the size and the location of the VSD. Small VSDs usually won't cause any type of symptoms, and might close on their own later on. Older kids or teens who have small VSDs that don't close usually have no symptoms other than the heart murmur which is the extra noise and if this is the case visiting a doctor is permitted. Medium and large VSDs that haven't been treated in childhood may cause noticeable symptoms. Babies may have faster breathing and get tired out…

cardiomyopathies. This disease affects the cardiovascular system. The heart has many important anatomical features. One of these being the ventricle of the heart. The ventricle of the heart is the main heart muscle that pumps blood. When HCM occurs the left ventricle within the heart thickens. When the thickening of the ventricle occurs there will be a decreased ventricular chamber volume, and abnormal ventricular relaxation. This deals with the diastolic aspect of the heart. Since the amount of…

only come, if the government was overhauled, African Americans got civil rights, and poverty was to end. When John F. Kennedy became president, he listened to the people’s demands. The Americans believed that the Old Left was problematic so they came up with the New Left. The New left believed that the government needed to do more than reform, the government ad to reorganize government institutions, change how the government provided for the needs of the Americans, and play a more active role in…

profession who worked for every 6 months while at military. On observation, the patient entered the room with a standard cane. The speech was not affected but there was evident drooping of lips on the left side. The patient’s chief complaint was weakness and reduced sensations in the left leg and left arm since June 2005 when he suffered from stroke. Also, the patient complained of difficulty in performing activities of daily living like buttoning his shirt,…

Ghost Hearts Doris A. Taylor, inventor/creator of the ghost hearts constantly harvest organs from the newly dead by re-engineering them. Doris is the director of the regenerative Medicine Research for the center of Cell and Organ Biotechnology at the Texas Heart Institute. Dr. Taylor worked on methods of decellularization and in 2008 she perfected the method. Decellularization is taking all the cells out of the organ leaving it with the lipids, sugar, and proteins. Ghost heart or a ghost-like…
