Transcathter Management for Neonatal Coarctation Coarctation of the aorta usually affects the aortic aspect of the insertion of the ductus arteriosus (Isthmus). Theoretically‚ it might be explained by a abnormal migration of the ductal smooth muscle cells into the periductal area in early the fetal life. This theory can explain the narrowing and constriction of the aorta in the periductal area. 1 Balloon angioplasty has been used for managing coarctation since early 1980s. There is strong evidence

ventricle contraction‚ PULMONARY VALVE- prevents blood from moving from pulmonary trun into right ventricle during ventricular relaxation‚ MITRAL VALVE- prevents blood from moving from left ventricle into right atrium during ventricular relaxation. AORTIC VALVE- prevents blood from moving from aorta into left ventricle during ventricular relaxation 6) Review the path of blood through the heart. As the right atrial wall contracts the blood passes through the tricuspid valve and enters the chamber

Therefore‚ a very rapid heart will often have

Heart valve replacements are more common than most people think. In the United States it is said that over 99‚000 heart valve surgeries are performed yearly. The majority of the valve replacement surgeries are to replace or repair the mitral or aortic valve‚ since the left side of the heart works harder than the right. There are several types of valve disease‚ the two most common are valvular stenosis and valvular insufficiency. Valvular stenosis occurs when the opening of the valve is smaller

Chapter 16 Notes The heart lies in the mediastinum and is surrounded by a doubled layered membrane called the pericardium. The outer most layer of the pericardium is called the fibrous pericardium‚ which anchors the heart to surrounding structures. The inner layer is called the serous pericardium and is composed of two layers. The outer portion is called the parietal pericardium‚ the inner portion is called the visceral pericardium (epicardium). Epicardium- outer most layer of the heart wall

identification of certain physical characteristics that are commonly prevalent in MFS subjects. Although Marfan Syndrome is characterized by a triad of symptoms‚ most patients only have a few manifestations. Loose joints‚ long thin extremities‚ and aortic aneurysms are the primary symptoms of MFS. These clinical manifestations may be present at birth or develop later in life (Marfan Syndrome‚ n.d.). Her explanation of the management of this disease was very specific. She explains that MFS management requires
