Atrial/Ventricular Septal Defect Repair Surgical Procedure Task An atrioventricular septal defect is a condition that results in a defect located in the middle of the heart. The condition takes place when a hole forms between the heart 's atrium and ventricular chambers. This defect causes complications and makes it difficult for the mitral valve to regulate blood flow in the heart. The deregulation of blood flow affects the lungs by allowing extra blood to flow into the organs. The heart then has to overwork itself in order to pump this extra blood out of the lungs and will cause the heart muscle to enlarge, leading to high blood pressure and even heart failure if left untreated. Atrioventricular septal defect is …show more content…

Both complete and partial atrioventricular septal defects can be repaired by surgery. During the surgery, the doctor will both close the hole in the heart’s chambers and reconstruct the valves that have been damaged. The hole is closed during the procedure by applying one or two patches to the septum. These patches will become a permanent fixture of the heart’s septum, as eventually, the lining of the heart will grow over the patches. The mitral valve is also reconstructed during surgery either by repairing it or, if needed, replacing it so that the valve will close tightly enough to regulate the blood flow. However, during a complete atrioventricular septal defect repair, the doctor will also divide the single mitral valve into two separate valves, with one each on the left and right sides of the repaired septum. If dividing the mitral valve is not possible for the procedure, then a heart valve replacement would be needed to proceed.
The anatomical system that is affected by this procedure is the cardiovascular system. The operation is performed in the chest cavity on the heart, with the septum and valves being reconstructed or replaced. The cardiovascular system is affected because this determines how well the heart is able to pump blood throughout the body. The surgical pathology of the atrioventricular septal defect repair procedure abnormal anatomy. This defect, which is created during gestation pre-birth, is considered

Pathophysiology When Pulmonary Stenosis is present, resistant to blood flow cause right ventricular hypertrophy – right atrial pressure will increase – reopening of the foramen ovale, shunting of unoxygenated blood into the left atrium, systemic circulation. Clinical manifestation: Cyanosis, characteristic murmur , cardiomegaly . Treatment: Baloon angioplasty (neonate).

Right chambers dimensions and right ventricular function were normal (TAPSE of 20 mm Hg), a calcific trileaflet aortic valve with normal leaflet excursion was observed, with normal gradients and no regurgitation. Mitral valve was normal, without regurgitation, and tricuspid valve and pulmonary valve were also normal. There was absence of pericadial effusion and both septae were

TAVI is an invasive procedure to aortic valve. In this invasive surgery a new valve that is a stainless steel tube with biological materials of cows, is inserted through a balloon catheter to the heart. This procedure can be done with local or general anaesthetic. This new valve insertion can be done with two common ways. Firstly is the transfemoral, which means through the femoral artery or second common way is the transapical way that is through a small cut to the left side to the chest.

Cardiac murmurs can be present at birth (congenital; often caused by malformations) or acquired and manifests later in the animals life. (Ex: disease of the cardiac muscles, disease of the cardiac valves, etc.). It is important to note that many animals with heart murmurs can live a long and happy life without

Normally, low-oxygen blood entering the right side of the heart stays on the right side, and subsequently oxygen-rich blood stays on the left side of the heart, where it is then pumped to the body and tissues. When a defect or "hole" is present between the atria (or upper chambers of heart), some oxygen-rich blood leaks back to the right side of the heart. It then goes back to the lungs even though it is already rich enough in oxygen. Because of this, there is a significant increase in the blood that goes to the lungs overall. Atrial septal defects can

The laboratory evaluation for sepsis was reported later as negative. Subsequent abdominal ultrasonogram revealed a left sided hydronephrosis. Echocardiogram confirmed the presence of multiple small ventricular septal defects (VSD), patent ductus arteriosus (PDA) of moderate size and markers of pulmonary hypertension. After discussion with surgical services two management options were considered; the first was surgical intervention to facilitate patient care and possibly ameliorate the course of illness and the second was the expectant conservative management. As the long-term outcomes were dependant on the final diagnosis, parents and treating team opted for no surgical intervention at this stage.

Over the following years, it laid the base for heart transplantation to become a well-established form of therapy for end-stage cardiac disease. Today, the process of a heart transplant had become a relatively routine for many doctors. With the new discovery of heart transplants actually being successful, it helped in other surgeries such as orthopedic heart transplantation, development of heterotopic heart transplantation, xenotransplantation and many more. In orthopedic heart transplantation there were 10 patients and each one lived various of months or years after the surgery. Dirk van Zyl was the one who survived the longest of more than 23 years.

Ablation of cardiac tissue using radio frequency catheter: This is to stop abnormal paths of the electrical signal generated in the heart 's natural pacemaker. They are used for these purpose radiofrequency electrodes that are mounted on special catheters that are inserted into the heart through an artery. Reconstructive plastic surgery of heart valves

First, it was 61 years ago, in 1954, that Dr. C. Walton Lillehei performed the fi rst cross-circulation procedures at the University. One year ago in January, Earl Bakken (the cofounder of Medtronic) turned 90 years old; Dr. Bakken has fi ve implanted Medtronic devices and continues to be an inspiration to those working in this fi eld. For the past 15 years, the University of Minnesota has presented the week-long short course Advanced Cardiac Physiology and Anatomy , which was designed specifi cally for the biomedical engineer working in the industry; this serves as the course textbook. Thus there was a need to update the textbook to include state-of-the-art information on a variety of topics related to cardiac anatomy, physiology, and devices. For example, six new chapters were added to this third edition, and all other chapters were carefully updated and/or greatly expanded.

The Pintails heart is like a mammals consisting of four chambers, two ventricles and two atria. The left ventricle pumps blood to all major organs in the body and throughout the rest, only excluding the lungs. This causes the left ventricle to be larger and more muscular. The lungs are fed blood from the right ventricle, which is the only the only function of that ventricle. The oxygenated blood coming from the lungs is fully separated from the oxygenated blood coming from other parts of the body.

Blood will flow from the left ventricle into the right ventricle with this particular defect. The defect causes increased blood flow into the lungs and can eventually result in pulmonary hypertension. Pulmonary hypertension will causes damage to the small blood vessels in lungs progressively through time. This is known as pulmonary vascular disease. As the damage progresses, pulmonary hypertension will increase and the small blood vessels become thickened and blocked affecting the flow of blood.

Pulmonary edema or congestion happens when the left ventricle of the heart fails. This is simply because the inefficiency of its ventricle to pump effectively causes the blood to back up to the pulmonary capillaries as the pulmonary venous blood rises its pressure into the tissues and alveoli impairing the gas exchange. Pulmonary congestion will be manifested in crackles, difficulty of breathing, frothy pink-tinged sputum and shortness of breath. In addition, the decreased amount of blood ejected from the left side causes ineffective tissue perfusion. This is detrimental to other vital organs such as the kidneys.

This artery also sends a branch to the moderator band and the anterior papillary muscle of the tricuspid valve (right ventricle), which is reasonable that the moderator is part of the septomarginal trabeculae of the interventricular septum; this artery is often called moderator artery (Laizzo,
