The drug ambrisentan is prescribed to patients suffering from pulmonary hypertension. In this rare form of hypertension, there is too much pressure exclusively in the pulmonary artery. The drug blocks the hormones that cause high blood pressure to develop. What is ambrisentan? Infographic on the anatomy and progression in pulmonary hypertension . Click to enlarge. … Ambrisentan: Effects, Uses & Risks
The pulmonary artery is an artery that carries deoxygenated blood from the heart to one of the two lungs. The two arteriae pulmonales are branches of the truncus pulmonalis, the pulmonary trunk that connects to the right ventricle of the heart. Sensuously, the two pulmonary arteries are referred to as the sinistra pulmonary artery for … Pulmonary Artery: Structure, Function & Diseases
The term hypoplastic left heart syndrome is used to describe a severely underdeveloped left heart and several other associated severe heart defects in newborns, most commonly involving the mitral and aortic valves. Survival after birth in these children is initially dependent on maintaining the prenatal short circuit between the pulmonary and systemic circulation via the … Hypoplastic Left Heart Syndrome: Causes, Symptoms & Treatment
Truncus arteriosis communis is the name given to a very rare heart defect in newborns caused by incomplete separation of the pulmonary arterial trunk from the arterial trunk of the systemic circulation. The aorta and pulmonary artery arise in a common trunk, resulting in mixing of the oxygen-depleted arterial blood of the pulmonary circulation with … Truncus Arteriosus Communis: Causes, Symptoms & Treatment
The heart rhythm can be divided into the two main phases systole, with tension phase and ejection phase, and diastole, with the relaxation phase. The tension phase is the beginning part of systole, in which the two leaflet valves are closed passively, by the increase in pressure, and also actively, by muscle tension, and the … Tension Phase: Function, Tasks, Role & Diseases
Double outlet right ventricle refers to various malformations of the heart. In this case, the large arteries, pulmonary artery and aorta, originate exclusively in the right ventricle. What is double outlet right ventricle? Double outlet right ventricle (DORV) is the English name for right double outlet ventricle. It refers to congenital malformations of the heart. … Double Outlet Right Ventricle: Causes, Symptoms & Treatment
Systole in clinical parlance refers to the tightening and subsequent contraction phase of the two ventricles of the heart. During the contraction phase, the two leaflet valves through which blood flowed from the two atria into the ventricles are closed, and the two leaflet valves in the left and right ventricles open. Blood is pumped … Systole: Function, Tasks, Role & Diseases
The ejection phase of systole follows the tense phase. During the ejection phase, stroke volume is pumped into the aorta. Synonymous with the ejection phase of systole is the term expulsion phase. Valvular defects, such as tricuspid regurgitation, can disrupt the ejection phase and cause pathologic changes in the heart. What is the ejection fraction? … Ejection Phase: Function, Tasks, Role & Diseases
The medulla oblongata and pons are the circulatory centers of the brain and constantly receive information on blood pressure and gas composition. From here, actions to regulate the circulation are initiated if necessary, which is known as central circulatory regulation. In cardiovascular disease, the system is disrupted. What is central circulatory regulation? The circulatory system … Central Circulatory Regulation: Function, Role & Diseases
Introduction Multiple factors play a role in the chances of survival after a pulmonary embolism. Special emphasis should be placed on immediate medical care after an embolism, as this significantly improves the chances of survival regardless of the severity of the disease. Of course, the size of the pulmonary embolism also plays a role. The … What are the chances of survival in case of a pulmonary embolism?
Chance of survival with a fulminant pulmonary embolism The fulminant pulmonary embolism describes the embolism in its most severe form. Fulminant means that the embolism occurs very suddenly and is followed by a very rapidly progressing and critical course. The early mortality rate here is over 15%. In most cases, a fulminant pulmonary embolism leads … Chance of survival with a fulminant pulmonary embolism | What are the chances of survival in case of a pulmonary embolism?
Which factors negatively influence the chances of survival of a pulmonary embolism? Factors that negatively influence the chances of survival after a pulmonary embolism concern the embolism itself, but previous illnesses of the affected person must also be taken into account. The principle applies to pulmonary embolism: the larger the embolism, the less favorable the … Which factors negatively influence the chances of survival of a pulmonary embolism? | What are the chances of survival in case of a pulmonary embolism?
