** **Atrial Septal Defect (ASD)** is a congenital heart defect characterized by an abnormal opening in the wall (septum) between the heart's two upper chambers (atria), leading to abnormal blood flow and potential complications. **CONTENT:** ### Overview Atrial Septal Defect (ASD) is a relatively common congenital heart defect that affects approximately 1 in 1,500 births. It occurs when there is an abnormal opening in the septum, the wall of tissue that separates the heart's two upper chambers (atria). This opening allows blood to flow between the left and right atria, disrupting normal blood flow and potentially leading to complications. ASDs can be classified into three main types: secundum, primum, and sinus venosus. ASDs can be asymptomatic at birth, but as the child grows, they may experience symptoms such as shortness of breath, fatigue, and palpitations. In some cases, ASDs may not be diagnosed until adulthood, when they can lead to complications such as arrhythmias, heart failure, and pulmonary hypertension. ### History/Background The first reported case of ASD was in 1861 by the French physician Claude Bernard. However, it wasn't until the 20th century that ASDs were more widely recognized and studied. In the 1950s and 1960s, surgical techniques for repairing ASDs were developed, and since then, the condition has become more manageable with advances in medical technology and treatment options. ### Key Information **Causes:** ASDs are usually caused by a genetic mutation or a combination of genetic and environmental factors during fetal development. They can also be associated with other congenital heart defects. **Symptoms:** Symptoms of ASDs may include: * Shortness of breath * Fatigue * Palpitations * Chest pain * Coughing * Swelling in the legs and feet **Diagnosis:** ASDs are typically diagnosed using echocardiography, a non-invasive test that uses sound waves to create images of the heart. Other diagnostic tests may include electrocardiography (ECG), chest X-rays, and cardiac catheterization. **Treatment:** Treatment options for ASDs depend on the size and location of the defect, as well as the individual's overall health. Surgical repair is usually the recommended treatment, which involves closing the abnormal opening in the septum. In some cases, catheter-based procedures may be used to close the defect. ### Significance ASDs can have significant consequences if left untreated, including arrhythmias, heart failure, and pulmonary hypertension. Early diagnosis and treatment can significantly improve outcomes and quality of life for individuals with ASDs. **INFOBOX:** - **Name:** Atrial Septal Defect (ASD) - **Type:** Congenital heart defect - **Date:** First reported case in 1861 - **Location:** Affects approximately 1 in 1,500 births worldwide - **Known For:** Abnormal opening in the septum between the heart's two upper chambers **TAGS:** Atrial Septal Defect, Congenital Heart Defect, Heart Health, Cardiology, Pediatric Cardiology, Cardiac Surgery, Echocardiography, Electrocardiography. **Important Note:** If you suspect you or a loved one may have an ASD, it is essential to seek medical attention from a qualified healthcare professional.

** This encyclopedia entry is about **Atrial Septal Defect (ASD)**, a congenital heart defect that affects the atrial septum, the wall of tissue that separates the right and left atria of the heart. **CONTENT:** ### Overview Atrial Septal Defect (ASD) is a congenital heart defect that occurs when there is an abnormal opening in the atrial septum, the wall of tissue that separates the right and left atria of the heart. This opening allows blood to flow between the two atria, which can lead to an increased workload on the heart and potentially cause complications. ASD is a relatively common congenital heart defect, affecting approximately 1 in 2,500 births. ASD can be classified into three main types: **Secundum ASD**, **Sinus Venosus ASD**, and **Primum ASD**. Secundum ASD is the most common type, accounting for approximately 75% of all ASD cases. Sinus Venosus ASD is a less common type that occurs near the superior vena cava, while Primum ASD is a rare type that occurs in the lower part of the atrial septum. Symptoms of ASD may not be apparent at birth, but they can develop over time. Common symptoms include shortness of breath, fatigue, and palpitations. In some cases, ASD may not cause any noticeable symptoms until adulthood. ### History/Background The first reported case of ASD dates back to 1672, when the French physician Jean Riolan described a patient with a heart defect that allowed blood to flow between the two atria. However, it wasn't until the 20th century that ASD was recognized as a distinct congenital heart defect. In the 1950s and 1960s, surgeons began to develop techniques for repairing ASD using open-heart surgery. The first successful ASD repair was performed by Dr. Alfred Blalock in 1945. Since then, ASD repair has become a routine procedure, with many patients undergoing surgery as children. ### Key Information Key facts about ASD include: * **Prevalence**: ASD affects approximately 1 in 2,500 births. * **Types**: ASD can be classified into three main types: Secundum, Sinus Venosus, and Primum. * **Symptoms**: Common symptoms include shortness of breath, fatigue, and palpitations. * **Treatment**: ASD can be treated with surgery or catheter-based procedures. * **Complications**: Untreated ASD can lead to complications such as heart failure, arrhythmias, and pulmonary hypertension. ### Significance ASD is a significant congenital heart defect that affects millions of people worldwide. Understanding ASD is crucial for developing effective treatments and improving patient outcomes. Advances in medical technology and surgical techniques have significantly improved the prognosis for patients with ASD, allowing many to lead normal, active lives. **INFOBOX:** - **Name**: Atrial Septal Defect (ASD) - **Type**: Congenital heart defect - **Date**: First reported case in 1672 - **Location**: Affects the atrial septum, the wall of tissue that separates the right and left atria of the heart - **Known For**: ASD is a relatively common congenital heart defect that can be treated with surgery or catheter-based procedures. **TAGS:** Congenital Heart Defect, Atrial Septal Defect, Heart Surgery, Cardiology, Pediatric Cardiology, Cardiovascular Disease, Heart Health, Medical Condition. **Important Note:** If you or a loved one has been diagnosed with ASD, it is essential to seek medical attention from a qualified healthcare professional.

** Mitral Valve Prolapse (MVP) is a condition where the mitral valve in the heart does not close properly, allowing blood to flow backward into the left atrium. **CONTENT:** ### Overview Mitral Valve Prolapse (MVP) is a common heart condition characterized by the mitral valve, which separates the left atrium and left ventricle, not closing properly. This allows blood to flow backward into the left atrium, which can lead to various symptoms and complications. MVP is often associated with a clicking or snapping sound heard during a heartbeat, known as a "click." The condition can be asymptomatic, but in some cases, it may cause chest pain, shortness of breath, or palpitations. MVP is a relatively common condition, affecting approximately 2-3% of the general population. It can occur at any age, but it is most commonly diagnosed in young adults and children. The exact cause of MVP is not fully understood, but it is believed to be related to genetic factors, as well as abnormalities in the mitral valve structure. ### History/Background The concept of mitral valve prolapse dates back to the early 20th century, when it was first described by physicians. However, it was not until the 1960s that the condition gained significant attention, with the development of echocardiography, a non-invasive imaging technique that allows for the visualization of the heart's structures. This led to a better understanding of the condition and its diagnosis. In the 1970s and 1980s, MVP became a topic of interest in the medical community, with numerous studies investigating its causes, symptoms, and treatment options. This led to the development of guidelines for the diagnosis and management of MVP, which have been updated over the years to reflect new research and evidence. ### Key Information * **Prevalence:** MVP affects approximately 2-3% of the general population. * **Age:** MVP can occur at any age, but it is most commonly diagnosed in young adults and children. * **Symptoms:** MVP can be asymptomatic, but it may cause chest pain, shortness of breath, or palpitations. * **Causes:** The exact cause of MVP is not fully understood, but it is believed to be related to genetic factors, as well as abnormalities in the mitral valve structure. * **Diagnosis:** MVP is typically diagnosed using echocardiography, which allows for the visualization of the mitral valve. * **Treatment:** Treatment for MVP depends on the severity of the condition and the presence of symptoms. In some cases, medication may be prescribed to alleviate symptoms, while in others, surgery may be necessary to repair or replace the mitral valve. ### Significance MVP is a significant condition because it can lead to various complications, including mitral regurgitation, heart failure, and arrhythmias. In some cases, MVP can also increase the risk of stroke and other cardiovascular events. Therefore, early diagnosis and treatment are crucial to prevent these complications and improve outcomes. **INFOBOX:** - **Name:** Mitral Valve Prolapse (MVP) - **Type:** Heart condition - **Date:** First described in the early 20th century - **Location:** Affects the mitral valve in the heart - **Known For:** Characterized by a clicking or snapping sound heard during a heartbeat **TAGS:** Heart condition, Mitral valve, Echocardiography, Cardiology, Cardiovascular disease, Heart failure, Arrhythmias, Stroke prevention.
