VENTRICULAR SEPTAL DEFECT

Аннотация

(Summary Explanation): A Ventricular Septal Defect (VSD) is a congenital condition where there is an abnormal opening in the septum dividing the heart's lower chambers (ventricles). This allows oxygen-rich blood from the left ventricle to mix with oxygen-poor blood in the right ventricle, leading to increased blood flow to the lungs. Depending on the size of the defect, symptoms may range from none to serious complications like heart failure or growth delays in infants. Diagnosis is usually through echocardiography, and treatment options vary from watchful waiting to surgical repair. Key Words: congenital heart defect, septum, ventricles, left-to-right shunt, heart murmur, pulmonary hypertension, echocardiogram, cardiac surgery, oxygenated/deoxygenated blood, hemodynamics. A congenital heart defect is a structural problem in the heart present at birth. One common example is a Ventricular Septal Defect (VSD), which involves an opening in the septum—the wall separating thetwo ventricles (the heart’s lower chambers). In a healthy heart, oxygenated blood from the lungs flows from the left ventricle to the body, while deoxygenated blood from the body flows from the right ventricle to the lungs. In a VSD, due to the hole in the septum, blood flows abnormally from the left to the right ventricle—a process called aleft-to-rightshunt. This causes extrabloodto bepumped intothelungs. This abnormal flow can be detected by a heart murmur, a sound made by turbulent blood flow, which is often the first clue in diagnosis. Over time, if untreated, the increased pressure in the lungs may lead to pulmonary hypertension, a serious condition where the lung arteries become stiffor narrow. Diagnosis is typically confirmed through an echocardiogram, a non-invasive ultrasound of the heart that shows thesizeand location ofthe defect andthedirection ofblood flow. www.wordlyknowledge.uz ILMIYMETODIK JURNAL JOURNAL OFIQRO –ЖУРНАЛ ИҚРО –IQRO JURNALI –volume 15,issue01,2025 ISSN:2181-4341, IMPACT FACTOR( RESEARCH BIB )–7,245,SJIF–5,431 Depending on the severity, treatment may include monitoring, medications, or cardiac surgery to close the defect. Understanding the hemodynamics—how blood flows through the heart and vessels—is essential indeciding theappropriate intervention. Ventricular Septal Defect is a significant congenital heart defect that affects the hemodynamics of the heart by creating a left-to-right shunt between the ventricles. Early detection through echocardiogram and timely intervention, including cardiac surgery when necessary, can prevent complications such as pulmonary hypertension and ensure a healthy life. Awareness of related signs like a heart murmur and the mixing of oxygenated and deoxygenated bloodis key inearly diagnosis andmanagement. VSDtypes There are four main types of ventricular septal defects. They differ in their location and the structure ofthehole(or holes). Thetypes ofVSDs are: Membranous. This is the most common type of VSD. These VSDs happen in the upper section ofthe wall between your ventricles. Muscular. These happen in the lower part of the wall. With this type, there’s often more than one hole. Inlet. This is a hole just below the tricuspid valve in your right ventricle and the mitral valve in your left ventricle. Whenbloodenters your ventricles, it mustpass aVSDthat connects them. Outlet. This kind of VSD creates a hole just before the pulmonary valve in your right ventricle and just before the aortic valve in your left ventricle. Blood has to go by the VSD on its way through both valves. Symptoms ofa VSD Ventricularseptal defect symptoms in anewborn maylook likeheart failure. These include: Shortness ofbreath, including fast breathing orstruggling to breathe Sweatiness orfatigueduring feeding Growth faltering (slowweight gain) Frequent respiratory infections A VSD heart defect in older children and adults can make them feel tired or out of breath during physical activity. Most people with VSDs don’t have symptoms because the hole is less than 3 millimeters around. This is about as big around as a toothpick and isn’t large enough to cause symptoms. But if the hole is large enough (or if there are multiple holes), it can cause blood to leak between the two heart chambers. A VSD that’s moderate (3 to 5 mm around) to large (6 to 10 mm around or about the sizeofapea) may cause symptoms.

But it does sometimes happen along with other issues present at birth, like heart defects, heart conditions or genetic disorders likeDown syndrome. In very rare cases, a heart attack can tear a hole between the ventricles and create a VSD. This type of ventricular septal defect or rupture is technically a side effect. But it’s still a dang
