Ventricle

The pulmonary circuit transports blood from the right ventricle to the pulmonary trunk to the lungs to the left atrium. This oxygenates the blood. The systemic circuit transports blood from the left ventricle through the aorta to the body’s tissues. Coronary arteries are used by the heart to collect oxygen-poor blood from the capillaries and deposit it into the right atrium. Toxins…

In 1971 Dr. Fontan and Dr. Baudet [26] did the first total cavopulmonary connection ‘‘Fontan Procedure’’ which is the final palliative stage for single ventricle patients. Since then, multiple techniques and modifications were invented. However, the ultimate goal of all different procedures is to achieve near complete separation of pulmonary venous return from systemic venous return. As such, all systemic venous circulation will be directed to the Fontan circulation (except the coronary sinus…

and the systemic circuit. The pulmonary circuit is simply the movement of blood from the heart, to the lungs, and back up to the heart again. Deoxygenated blood leaves the right ventricle of the heart and runs through the pulmonary artery; from here, the blood is pumped through the right atrium and into the right ventricle. The blood continues its course and travels through the lungs. While in the lungs, the deoxygenated blood releases its carbon dioxide and picks up oxygen through the process…

chambers. 1. Right atrium 2. Left atrium 3. Right ventricle 4. Left ventricle The atria are a lot smaller than the ventricles. The walls of the atria are a lot thinner and a lot less muscular than the ventricles. The atria are there to act as receiving chambers for blood. They are connected to the veins which takes the blood to the heart. The ventricles are much larger they are also much stronger to be able to pump blood out of the heart. The ventricles are connected to the arteries that…

control the rich and poor oxygenated blood to mix. These are the right and left side that contains the four chambers; right atrium and right ventricle for right side and the left contains the left atrium and left ventricles. The upper part which are the left and right atrium are the one receiving the blood meanwhile the lower chambers, the left and right ventricle, are the one that pumps the blood our of our heart as the heart contracted. On the right atrium, there is a part called superior…

generating an electrical impulse which travels to the left and right atria, causing them to contract. Following the start of atrial depolarization, the impulse quickly arrives at the atrioventricular node which is responsible for the contraction of ventricle. The SA node creates the electrical impulse which causes the heart to beat, but the Autonomic Nervous System controls the heart rate and the strength of heart contractions. The ANS consists of two parts, the Sympathetic Nervous System and…

properly. When the cardiac cycle and BP are affected then the body is in danger of being greatly damaged. The cardiac cycle is what causes the BP to rise and fall. This occurs first through a ventricular contraction. When this contraction of the ventricles happens the blood is forced to go into the pulmonary artery and the aorta. This causes the pressure to increase…

Left side ventricle CHF have common respiratory signs are increased rate of breathing and also in increase of working to breath such as jugular venous distention. Rales or crackles can also occur because of the buildup of fluid in the lungs that can be heard when the patient inhales and exhales. When there’s fluid in the lungs it can also cause cyanosis which will then develop as a late sign of pulmonary edema. Left sided can cause a backwards failure of the atrium and ventricles that will which…

Right Ventricular Function Assessment in Single LAD lesion Patients Using Strain and Strain Rate Imaging Abstract Background. Strain and strain rate imaging is currently the most popular echocardiographic technique that reveals subclinical myocardial damage, no available data on this imaging method with regard to assessing right ventricular involvement in single LAD lesion. Aim. to evaluate right ventricular regional functions using strain and strain rate imaging tissue Doppler method in…

reduced diastolic volume of either [one] or both ventricles with normal or near normal systolic function and wall thickness.” There are many types of Cardiomyopathy, Restrictive cardiomyopathy is the least common type. The tell-tale sign of RCM is diastolic dysfunction. Diastolic dysfunction is when the heart does not fill up correctly, either too slowly or too quickly. This can occur in one or both ventricles, and the wall thickness of the left ventricle is usually increased. An…
