• #1 Eisenmenger Syndrome: Background, Pathophysiology, Etiology

  https://emedicine.medscape.com/article/154555-overview

  Eisenmenger syndrome occurs in patients with large, congenital cardiac or surgically-created extracardiac left-to-right shunts. These shunts initially cause increased pulmonary blood flow. If left unchecked, increased pulmonary blood flow and/or elevated pulmonary arterial pressure can result in remodeling of the pulmonary microvasculature, with subsequent obstruction to pulmonary blood flow. This is commonly referred to as pulmonary vascular obstructive disease (PVOD). […] The progression to Eisenmenger physiology is represented by a spectrum of morphologic changes in the capillary bed that progress from reversible lesions to irreversible ones. Endothelial dysfunction and smooth muscle proliferation result from the changes in flow and pressure, increasing the PVR. […] The cellular and molecular mechanisms remain fully uncharacterized, representing pathways of inflammation, cell proliferation, increase in the extracellular matrix, vasoconstriction, fibrosis, and intravascular thrombosis.

  https://www.cardionerds.com/328-achd-eisenmenger-syndrome-with-dr-alexander-sasha-opotowsky/

  Eisenmenger syndrome is an end-stage complication of congenital heart disease that occurs when a left to right shunt causes pulmonary over-circulation, leading to vascular remodeling, increased vascular resistance, and ultimately even shunt reversal. […] First described in 1897 by Victor Eisenmenger, Eisenmenger syndrome is a long-term complication of unrepaired left to right shunts, resulting from pulmonary vascular remodeling and pulmonary hypertension. This eventually leads to reversal of the shunt, with right to left flow causing cyanosis. […] The pulmonary vasculature is not used to seeing the increased flow it receives in the context of a left to right shunt. Over time this leads to an increase in pulmonary vascular resistance and pulmonary hypertension. When pulmonary pressures exceed systemic pressures, this causes shunt reversal with right to left shunting causing deoxygenated blood to cross from right side of the heart to the left side bypassing the lungs and causing cyanosis.

  Eisenmenger syndrome (ES) is a constellation of symptoms that arise from a congenital heart defect and result in large anatomic shunts. […] Any heart defect that leads to the development of PAH can cause Eisenmenger syndrome. This is commonly seen in atrial septal defects (ASD), ventricular septal defects (VSD), atrioventricular septal defects, and patent ductus arteriosus (PDA), but it can occur in more complex lesions as well. Unrepaired Tetralogy of Fallot may also result in Eisenmenger syndrome. […] Without early repair, reversal of a left-to-right shunt may result in a bidirectional or right-to-left shunt. The subsequent hypoxemia due to this shunt may not be responsive to oxygen.

  Eisenmenger syndrome is usually caused by an unrepaired hole between the main blood vessels or chambers of the heart. The hole is called a shunt. A shunt is a heart problem present at birth, which means it’s a congenital heart defect. […] Congenital heart defects that can cause Eisenmenger syndrome include: […] Ventricular septal defect. This is the most common cause of Eisenmenger syndrome. There is a hole in the wall of tissue between the bottom heart chambers. […] In any of these heart conditions, blood flows in a way it usually doesn’t. As a result, pressure rises in the pulmonary artery. Over time, the increased pressure damages the smaller blood vessels in the lungs. […] In Eisenmenger syndrome, blood pressure rises in the side of the heart that has oxygen-poor blood, also called blue blood. The blue blood goes through the hole in the heart or blood vessels. Oxygen-rich and oxygen-poor blood now mix. This causes low blood oxygen levels.

• #9 Eisenmenger syndrome | Radiology Reference Article | Radiopaedia.org

  https://radiopaedia.org/articles/eisenmenger-syndrome-1?lang=us

  The Eisenmenger syndrome is a complication of an uncorrected high-flow, high-pressure congenital heart anomaly leading to chronic pulmonary arterial hypertension and shunt reversal. […] In general, the shunts that lead to Eisenmenger syndrome share high pressure and high flow. As such the three lesions that account for most cases are: ventricular septal defect (VSD), atrioventricular septal defect (AVSD), and patent ductus arteriosus (PDA). […] Exposure of the right heart and pulmonary circulation to increased flow and pressure results in changes including arteriolar medial hypertrophy, intimal proliferation and fibrosis, and eventual capillary and arteriolar occlusion due to the development of plexiform lesions and necrotizing arteritis. […] Concurrently, and in response to increased vascular resistance in the pulmonary vascular bed, the right ventricle hypertrophies, generating ever-increasing pressures. Eventually, a critical balance is reached at which point the pressures generated on the right are higher than those on the left, and the shunt reverses, with de-oxygenated blood passing into the systemic circulation and resulting in cyanosis. […] The radiographic differential is essentially that of pulmonary arterial hypertension.

• #11 Eisenmenger syndrome – Humanitas.net

  https://www.humanitas.net/diseases/eisenmenger-syndrome/

  The main cause for Eisenmenger syndrome is defect in the heart caused by abnormal blood circulation. A heart defect causes a hole (shunt) to develop between two chambers of the heart, causing blood to circulate abnormally in the heart and lungs. Increased blood flow returns to the lungs instead of going to the rest of your body, making it difficult to receive oxygen to other parts of the body. […] Heart defects that can cause Eisenmenger syndrome include: Ventricular septal defect: A hole (shunt) that develops in the wall of tissue that divides the left and right ventricles of the heart, causing blood to circulate abnormally in the heart and lungs. Atrial septal defect. A hole (shunt) that develops in the wall of tissue that divides the right and left sides of the upper chambers of the heart (atria). Patent ductus arteriosus. An opening between the pulmonary artery that carries oxygen-poor blood to the lungs and the artery that carries oxygen-rich blood to the rest of the body (aorta) Atrioventricular canal defect. A large hole that develops in the center of the heart where the walls between the upper chambers (atria) and lower chambers (ventricles) meet.

• #12 Eisenmenger Syndrome – ACHA

  https://www.achaheart.org/your-heart/educational-qas/types-of-heart-defects/eisenmenger-syndrome/

  The incidence of ES has decreased with advancements in cardiac surgery since the 1950s. Although the overall incidence is not known, ES occurs in from 1-6% of CHD patients in regions with well-developed systems for CHD care. It can occur more frequently in areas with less access to advanced CHD care. This is because septal defects are repaired more often and earlier. ES is more often diagnosed in young adulthood as the damage takes years to occur but may vary from one patient to another. […] Which congenital heart defects cause ES? Unrepaired ventricular septal defects (VSD) that are moderate to large. Unrepaired atrial septal defects (ASD) that are moderate to large. Atrioventricular (AV) canal defect or complete AV canal. Patent ductus arteriosus (PDA). Other types of complex congenital heart disease, such as single ventricle or double inlet left ventricle.

  Eisenmenger syndrome is a condition that affects blood flow from the heart to the lungs in some people who were born with structural problems of the heart. […] Eisenmenger syndrome is a condition that results from abnormal blood circulation caused by a defect in the heart. Most often, people with this condition are born with a hole between the two larger pumping chambers — the left and right ventricles — of the heart (ventricular septal defect). The hole allows blood that has already picked up oxygen from the lungs to flow back into the lungs, instead of going out to the rest of the body. […] Other heart defects that can lead to Eisenmenger syndrome include: Atrioventricular canal defect, Atrial septal defect, Cyanotic heart disease, Patent ductus arteriosus, Truncus arteriosus. […] Over many years, increased blood flow can damage the small blood vessels in the lungs. This causes high blood pressure in the lungs. As a result, the blood flow goes backward through the hole between the two pumping chambers. This allows oxygen-poor blood to travel to the rest of the body.

• #25 Eisenmenger Syndrome: Symptoms, Cause, Treatment

  https://www.webmd.com/heart-disease/eisenmenger-syndrome-facts

  Eisenmenger syndrome is a kind of high blood pressure in the lungs, called pulmonary arterial hypertension. It’s caused by a heart defect that lets blood from opposite sides of your heart mix together. Usually, this happens when there’s a hole between the two lower chambers of your heart, called the ventricles, or a hole between the upper chambers, called the atria. […] Over time, the blood vessels of your lungs are damaged. They get stiff and thick, and the pressure inside them rises. Eventually, pressure also rises in the right side of your heart. That forces blood from the right side into the left, so blood that hasn’t made it to the lungs yet is mixed with the oxygen-rich blood being pumped out to your body. Organs and tissues don’t get enough oxygen, and that causes serious problems. […] This damage happens slowly, and symptoms can take many years to show up. The process starts before a child turns 2, and by the teenage years, blood starts to flow the opposite way through the hole in the heart and oxygen levels drop. Health problems start in the teens and 20s.

• #27 Eisenmenger’s Effects

  https://www.rnceus.com/vsd/eisen22.html

  Eisenmengers syndrome (ES) is an advanced form of pulmonary arterial hypertension (PAH) that is associated with congenital heart defects (CHD). A number of congenital heart defects can increase the flow and blood pressure in the pulmonary arterial vasculature. The cardiac defects most associated with ES are ventricular septal defects (VSDs), atrial septal defects (ASDs), atrioventricular septal defects, and patent ductus arteriosus. […] Early surgical correction of CHD has reduced the incidence of ES, but once PAH has developed surgical correction is contraindicated. […] The disease model begins with: An uncorrected left-to-right shunt that increases pulmonary artery pressure and blood flow. Increased blood flow causes shear stress on the endothelium and circumfrential stretch of the walls of the pulmonary arteries. Endothelial stress injury leads to vascular remodeling characterized by inflammation, intimal proliferation of smooth muscle, deposition of extracellular matrix and intravascular thrombosis.

  Eisenmenger syndrome develops when too much blood flows through the arteries that carry blood to your lungs from your heart. […] Eisenmenger syndrome is usually the result of one or more untreated congenital (present at birth) heart defects. […] Eisenmenger syndrome typically develops in children and young adults who have an uncorrected ventricular septal defect (VSD). […] Eisenmenger syndrome also can result from other unrepaired congenital heart defects such as: Atrioventricular canal defect, Atrial septal defect, Cyanotic heart disease, Patent ductus arteriosus, Tetralogy of Fallot, Truncus arteriosus.

• #39 Eisenmenger Syndrome: Symptoms, Cause, Treatment

  https://www.webmd.com/heart-disease/eisenmenger-syndrome-facts

  Eisenmenger syndrome is a kind of high blood pressure in the lungs, called pulmonary arterial hypertension. It’s caused by a heart defect that lets blood from opposite sides of your heart mix together. Usually, this happens when there’s a hole between the two lower chambers of your heart, called the ventricles, or a hole between the upper chambers, called the atria. […] Over time, the blood vessels of your lungs are damaged. They get stiff and thick, and the pressure inside them rises. Eventually, pressure also rises in the right side of your heart. That forces blood from the right side into the left, so blood that hasn’t made it to the lungs yet is mixed with the oxygen-rich blood being pumped out to your body. Organs and tissues don’t get enough oxygen, and that causes serious problems. […] This damage happens slowly, and symptoms can take many years to show up. The process starts before a child turns 2, and by the teenage years, blood starts to flow the opposite way through the hole in the heart and oxygen levels drop. Health problems start in the teens and 20s.

  Eisenmenger syndrome is a condition that affects blood flow from the heart to the lungs in some people who were born with structural problems of the heart. […] Eisenmenger syndrome is a condition that results from abnormal blood circulation caused by a defect in the heart. Most often, people with this condition are born with a hole between the two larger pumping chambers — the left and right ventricles — of the heart (ventricular septal defect). The hole allows blood that has already picked up oxygen from the lungs to flow back into the lungs, instead of going out to the rest of the body.

  Eisenmenger syndrome (ES) is the most severe form of pulmonary arterial hypertension (PAH) related to congenital heart disease (CHD). It results from a cardiac defect allowing significant systemic-to-pulmonary (left-to-right) shunting, which triggers the development of pulmonary vascular disease (PVD) if the defect is not repaired in a timely fashion. […] Long-term exposure of the pulmonary bed to increased pulmonary flow and pressure from a post-tricuspid (eg, ventricular septal defect [VSD]) left-right shunt results in vascular remodeling and dysfunction. This, in turn, leads to a rise in PVR, which, if severe enough, results in reversal of the shunt and the clinical cyanosis characteristic of ES. […] The exact prevalence of ES is not known. According to historical data and before the advent of timely intervention, ~8% of patients with CHD and 11% of those with left-to-right shunts developed ES.

  Eisenmenger syndrome occurs when blood flows from the right to the left side of the heart across a structural heart lesion, bypassing the lungs. Three underlying lesions can result in Eisenmenger syndrome: Atrial septal defect, Ventricular septal defect, Patent ductus arteriosus. […] Eisenmenger syndrome can develop within a few years with large lesions or in adulthood with small shunts. It can develop more rapidly during pregnancy. […] Early management of the underlying lesion can prevent Eisenmenger syndrome. […] Eisenmenger syndrome reduces life expectancy by around 20 years compared with healthy individuals. The main causes of death are heart failure, infection, thromboembolism and haemorrhage. The mortality can be up to 50% in pregnancy.

  Eisenmenger syndrome (pulmonary vascular disease leading to shunt reversal) is a result of an untreated large left-to-right shunt (interatrial, interventricular, or aortopulmonary) and increased pulmonary perfusion, leading to severe irreversible pulmonary hypertension and shunt reversal (ie, a right-to-left shunt). It is a complication of simple or complex defects associated with large shunts. Eisenmenger syndrome frequently develops in childhood; in adults, the diagnosis is made mainly in patients with an atrioventricular septal defect, large interatrial shunt, nonrestrictive ventricular septal defects, or patent ductus arteriosus (PDA). […] The most common causes of death are heart failure, sudden cardiac death, and massive hemoptysis. The risk factors for severe complications or death include pregnancy, general anesthesia, dehydration, hemorrhage, surgical procedures (noncardiac), diuretics overuse, certain oral contraceptives, anemia (usually after unnecessary phlebotomies), cardiac catheterization, intravenous therapy, and pulmonary infections.

  Eisenmenger Syndrome most commonly occurs as the consequence of a hole in the heart, for example a ventricular septal defect (VSD) or an atrial septal defect (ASD). […] It can also occur due to a patent ductus arteriosus (PDA) or due to more complex heart conditions. […] These conditions allow increased blood flow into the lungs, usually at high blood pressure. […] High blood pressure in the lungs is known as pulmonary arterial hypertension and Eisenmenger syndrome is one cause of pulmonary hypertension. […] Eisenmenger syndrome results in less blood going through the lungs and therefore less oxygen being picked up. […] Eisenmenger Syndrome is a major heart condition which cannot be cured by surgery and it needs careful follow-up in the ACHD clinic. […] Pregnancy is very dangerous for women with Eisenmenger Syndrome. The risk of dying during pregnancy is up to 50%.

  The placenta has low resistance to blood flow, meaning that it is very easy for blood to go through the blood vessels in the placenta. In women with Eisenmenger syndrome this results in more blood going around the body and less blood going through the lungs, making oxygen levels even lower than they are prior to the pregnancy.

  Eisenmenger syndrome is an end-stage complication of congenital heart disease that occurs when a left to right shunt causes pulmonary over-circulation, leading to vascular remodeling, increased vascular resistance, and ultimately even shunt reversal. […] First described in 1897 by Victor Eisenmenger, Eisenmenger syndrome is a long-term complication of unrepaired left to right shunts, resulting from pulmonary vascular remodeling and pulmonary hypertension. This eventually leads to reversal of the shunt, with right to left flow causing cyanosis. […] The pulmonary vasculature is not used to seeing the increased flow it receives in the context of a left to right shunt. Over time this leads to an increase in pulmonary vascular resistance and pulmonary hypertension. When pulmonary pressures exceed systemic pressures, this causes shunt reversal with right to left shunting causing deoxygenated blood to cross from right side of the heart to the left side bypassing the lungs and causing cyanosis.

  Eisenmenger syndrome (ES) is the most severe form of pulmonary arterial hypertension (PAH) related to congenital heart disease (CHD). It results from a cardiac defect allowing significant systemic-to-pulmonary (left-to-right) shunting, which triggers the development of pulmonary vascular disease (PVD) if the defect is not repaired in a timely fashion. […] Long-term exposure of the pulmonary bed to increased pulmonary flow and pressure from a post-tricuspid (eg, ventricular septal defect [VSD]) left-right shunt results in vascular remodeling and dysfunction. This, in turn, leads to a rise in PVR, which, if severe enough, results in reversal of the shunt and the clinical cyanosis characteristic of ES. […] The exact prevalence of ES is not known. According to historical data and before the advent of timely intervention, ~8% of patients with CHD and 11% of those with left-to-right shunts developed ES.

  Eisenmenger syndrome is a life-threatening condition caused as a complication of untreated congenital heart defects. […] The most common cause of Eisenmenger syndrome is an unrepaired hole between the heart chambers or the heart’s main blood vessels. A shunt is a congenital heart defect; that is, it is present at birth. […] Various conditions of the heart can cause Eisenmenger syndrome, which is as follows: Ventricular Septal Defect: It is the most common cause of this condition. In this, there is a hole between the ventricles of the heart. […] The above four heart defects change the normal pathway of blood flow in the heart and, thus, the body. Hence, there is an increase in blood pressure within the pulmonary vessels. After some time, these changes damage the smaller blood vessels in the lungs. These damaged blood vessels make it difficult to transport blood to the lungs.
