How to recognize early signs/red flags - Video 1 ASD

Due to the communication between the atria that occurs in ASDs, disease entities or complications from the condition are possible. Patients with an uncorrected atrial septal defect may be at increased risk for developing a cardiac arrhythmia, as well as more frequent respiratory infections.

ASDs, and particularly PFOs, are a predisposing risk factor for decompression sickness in divers because a proportion of venous blood carrying inert gases, such as helium or nitrogen does not pass through the lungs.

If some of the inert gas-laden blood passes through the PFO, it avoids the lungs and the inert gas is more likely to form large bubbles in the arterial blood stream causing decompression sickness.

If a net flow of blood exists from the left atrium to the right atrium, called a left-to-right shunt, then an increase in the blood flow through the lungs happens.

Initially, this increased blood flow is asymptomatic, but if it persists, the pulmonary blood vessels may stiffen, causing pulmonary hypertension, which increases the pressures in the right side of the heart, leading to the reversal of the shunt into a right-to-left shunt.

Reversal of the shunt occurs, and the blood flowing in the opposite direction through the ASD is called Eisenmenger's syndrome, a rare and late complication of an ASD.

Venous thrombus clots in the veins are quite common. Embolizations dislodgement of thrombi normally go to the lung and cause pulmonary emboli. In an individual with ASD, these emboli can potentially enter the arterial system, which can cause any phenomenon attributed to acute loss of blood to a portion of the body, including cerebrovascular accident stroke , infarction of the spleen or intestines , or even a distal extremity i.

This is known as a paradoxical embolus because the clot material paradoxically enters the arterial system instead of going to the lungs.

Some recent research has suggested that a proportion of cases of migraine may be caused by PFO. While the exact mechanism remains unclear, closure of a PFO can reduce symptoms in certain cases.

The high frequency of these facts finding statistically significant relationships between PFO and migraine difficult i. In a large randomized controlled trial , the higher prevalence of PFO in migraine patients was confirmed, but migraine headache cessation was not more prevalent in the group of migraine patients who underwent closure of their PFOs.

The many types of atrial septal defects are differentiated from each other by whether they involve other structures of the heart and how they are formed during the developmental process during early fetal development.

The secundum atrial septal defect usually arises from an enlarged foramen ovale , inadequate growth of the septum secundum , or excessive absorption of the septum primum.

An ostium secundum ASD accompanied by an acquired mitral valve stenosis is called Lutembacher's syndrome. Most individuals with an uncorrected secundum ASD do not have significant symptoms through early adulthood.

Symptoms are typically decreased exercise tolerance, easy fatigability, palpitations , and syncope. Complications of an uncorrected secundum ASD include pulmonary hypertension , right-sided heart failure , atrial fibrillation or flutter , stroke , and Eisenmenger's syndrome.

A patent foramen ovale PFO is a remnant opening of the fetal foramen ovale , which normally closes after a person's birth.

In medical use, the term "patent" means open or unobstructed. On echocardiography, shunting of blood may not be noted except when the patient coughs.

Clinically, PFO is linked to stroke , sleep apnea , migraine with aura , and decompression sickness. No cause is established for a foramen ovale to remain open instead of closing naturally, but heredity and genetics may play a role.

The mechanism by which a PFO may play a role in stroke is called paradoxical embolism. In the case of PFO, a blood clot from the venous circulatory system is able to pass from the right atrium directly into the left atrium via the PFO, rather than being filtered by the lungs, and thereupon into systemic circulation toward the brain.

PFO is more prevalent in patients with cryptogenic stroke than in patients with a stroke of known cause. Statistically speaking, this is particularly true for patients who have a stroke before the age of Some data suggest that PFOs may be involved in the pathogenesis of some migraine headaches.

A defect in the ostium primum is occasionally classified as an atrial septal defect, [27] but it is more commonly classified as an atrioventricular septal defect.

A sinus venosus ASD is a type of atrial septum defect in which the defect involves the venous inflow of either the superior vena cava or the inferior vena cava.

It is located at the junction of the superior vena cava and the right atrium. It is frequently associated with anomalous drainage of the right-sided pulmonary veins into the right atrium instead of the normal drainage of the pulmonary veins into the left atrium.

Common or single atrium is a failure of development of the embryologic components that contribute to the atrial septal complex. It is frequently associated with heterotaxy syndrome.

The interatrial septum can be divided into five septal zones. If the defect involves two or more of the septal zones, then the defect is termed a mixed atrial septal defect.

In unaffected individuals, the chambers of the left side of the heart are under higher pressure than the chambers of the right side because the left ventricle has to produce enough pressure to pump blood throughout the entire body, while the right ventricle needs only to produce enough pressure to pump blood to the lungs.

This extra blood from the left atrium may cause a volume overload of both the right atrium and the right ventricle. If untreated, this condition can result in enlargement of the right side of the heart and ultimately heart failure.

Any process that increases the pressure in the left ventricle can cause worsening of the left-to-right shunt. This includes hypertension, which increases the pressure that the left ventricle has to generate to open the aortic valve during ventricular systole , and coronary artery disease which increases the stiffness of the left ventricle, thereby increasing the filling pressure of the left ventricle during ventricular diastole.

The left-to-right shunt increases the filling pressure of the right heart preload and forces the right ventricle to pump out more blood than the left ventricle.

This constant overloading of the right side of the heart causes an overload of the entire pulmonary vasculature.

Eventually, pulmonary hypertension may develop. The pulmonary hypertension will cause the right ventricle to face increased afterload.

The right ventricle is forced to generate higher pressures to try to overcome the pulmonary hypertension. This may lead to right ventricular failure dilatation and decreased systolic function of the right ventricle.

If the ASD is left uncorrected, the pulmonary hypertension progresses and the pressure in the right side of the heart becomes greater than the left side of the heart.

This reversal of the pressure gradient across the ASD causes the shunt to reverse - a right-to-left shunt. This phenomenon is known as Eisenmenger's syndrome.

Once right-to-left shunting occurs, a portion of the oxygen-poor blood gets shunted to the left side of the heart and ejected to the peripheral vascular system.

This causes signs of cyanosis. Most individuals with a significant ASD are diagnosed in utero or in early childhood with the use of ultrasonography or auscultation of the heart sounds during physical examination.

The development of signs and symptoms due to an ASD are related to the size of the intracardiac shunt. Individuals with a larger shunt tend to present with symptoms at a younger age.

Adults with an uncorrected ASD present with symptoms of dyspnea on exertion shortness of breath with minimal exercise , congestive heart failure , or cerebrovascular accident stroke.

They may be noted on routine testing to have an abnormal chest X-ray or an abnormal ECG and may have atrial fibrillation.

If the ASD causes a left-to-right shunt, the pulmonary vasculature in both lungs may appear dilated on chest X-ray, due to the increase in pulmonary blood flow.

The physical findings in an adult with an ASD include those related directly to the intracardiac shunt, and those that are secondary to the right heart failure that may be present in these individuals.

Upon auscultation of the heart sounds , a systolic ejection murmur may be heard that is attributed to the pulmonic valve, due to the increased flow of blood through the pulmonic valve rather than any structural abnormality of the valve leaflets.

In unaffected individuals, respiratory variations occur in the splitting of the second heart sound S 2. During respiratory inspiration, the negative intrathoracic pressure causes increased blood return into the right side of the heart.

The increased blood volume in the right ventricle causes the pulmonic valve to stay open longer during ventricular systole.

This causes a normal delay in the P 2 component of S 2. During expiration, the positive intrathoracic pressure causes decreased blood return to the right side of the heart.

The reduced volume in the right ventricle allows the pulmonic valve to close earlier at the end of ventricular systole, causing P 2 to occur earlier.

In individuals with an ASD, a fixed splitting of S 2 occurs because the extra blood return during inspiration gets equalized between the left and right atria due to the communication that exists between the atria in individuals with ASD.

The right ventricle can be thought of as continuously overloaded because of the left-to-right shunt, producing a widely split S2. Because the atria are linked via the atrial septal defect, inspiration produces no net pressure change between them, and has no effect on the splitting of S2.

In transthoracic echocardiography , an atrial septal defect may be seen on color flow imaging as a jet of blood from the left atrium to the right atrium.

If agitated saline is injected into a peripheral vein during echocardiography, small air bubbles can be seen on echocardiographic imaging.

Bubbles traveling across an ASD may be seen either at rest or during a cough. Bubbles only flow from right atrium to left atrium if the right atrial pressure is greater than left atrial.

Because better visualization of the atria is achieved with transesophageal echocardiography, this test may be performed in individuals with a suspected ASD which is not visualized on transthoracic imaging.

Newer techniques to visualize these defects involve intracardiac imaging with special catheters typically placed in the venous system and advanced to the level of the heart.

This type of imaging is becoming more common and involves only mild sedation for the patient typically.

If the individual has adequate echocardiographic windows, use of the echocardiogram to measure the cardiac output of the left ventricle and the right ventricle independently is possible.

In this way, the shunt fraction can be estimated using echocardiography. The ECG findings in atrial septal defect vary with the type of defect the individual has.

Individuals with atrial septal defects may have a prolonged PR interval a first-degree heart block. The prolongation of the PR interval is probably due to the enlargement of the atria common in ASDs and the increased distance due to the defect itself.

Both of these can cause an increased distance of internodal conduction from the SA node to the AV node. A common finding in the ECG is the presence of incomplete right bundle branch block , which is so characteristic that if it is absent, the diagnosis of ASD should be reconsidered.

ASD with pulmonary embolism resulting in a right to left shunting of blood [36]. Most patients with a PFO are asymptomatic and do not require any specific treatment.

In those where a comprehensive evaluation is performed and an obvious etiology is not identified, they are defined as having a cryptogenic stroke.

The mechanism for stroke is such individuals is likely embolic due to paradoxical emboli, a left atrial appendage clot, a clot on the inter-atrial septum, or within the PFO tunnel.

Until recently, patients with PFO and cryptogenic stroke were treated with antiplatelet therapy only.

Previous studies did not identify a clear benefit of PFO closure over antiplatelet therapy in reducing recurrent ischemic stroke. However, based on new evidence [39] [40] [41] and systematic review in the field, [38] percutaneous PFO closure in addition to antiplatelet therapy is suggested for all who meet all the following criteria: A variety of PFO closure devices may be implanted via catheter-based procedures.

People with ASD often have problems with social, emotional, and communication skills. They might repeat certain behaviors and might not want change in their daily activities.

Many people with ASD also have different ways of learning, paying attention, or reacting to things. Diagnosing ASD can be difficult since there is no medical test, like a blood test, to diagnose the disorders.

ASD can sometimes be detected at 18 months or younger. By age 2, a diagnosis by an experienced professional can be considered very reliable.

This delay means that children with ASD might not get the early help they need. There is currently no cure for ASD. Services can include therapy to help the child talk, walk, and interact with others.

Even if your child has not been diagnosed with an ASD, he or she may be eligible for early intervention treatment services.

The Individuals with Disabilities Education Act IDEA says that children under the age of 3 years 36 months who are at risk of having developmental delays may be eligible for services.

These services are provided through an early intervention system in your state. Through this system, you can ask for an evaluation.

In addition, treatment for particular symptoms, such as speech therapy for language delays, often does not need to wait for a formal ASD diagnosis.

We do not know all of the causes of ASD. However, we have learned that there are likely many causes for multiple types of ASD. There may be many different factors that make a child more likely to have an ASD, including environmental, biologic and genetic factors.

ASD continues to be an important public health concern. Understanding the factors that make a person more likely to develop ASD will help us learn more about the causes.
