The best pediatricians for heart disease ### Congenital heart diseases **coarctation of the aorta** Coarctation of the aorta occurs when the main artery of the body is narrowed.. In this condition, less blood flows inside it.... This congenital heart disease may present itself alone or in combination with other types of congenital heart disease such as defects of the interventricular wall or ductus arteriosus.... Aortic stenosis can be severe and require treatment shortly after the birth of the **child** or it may occur in the late stages of life. Aortic valve stenosis is a dangerous congenital defect of the heart... the aortic valve, which controls the flow of blood from the heart's main pump chamber (left ventricle) to the body's main artery (aorta), narrows... because it is more difficult for the heart to pump.. ** ductus arteriosus** When the **fetus** is growing in the mother's womb, a blood vessel called the ductus arteriosus directly connects the pulmonary artery to the aorta.. This vessel directs blood from the lungs to the aorta.. It's easy, but if ignored.. it causes irreparable problems for the heart... **Pulmonary valve stenosis** In pulmonary valve stenosis, the pulmonary valve that controls the flow of blood from the right ventricle of the heart to the lungs is narrower than normal. In this congenital heart disease, which is a rare disease, the valve on the right side of the heart (tricuspid valve) that separates the right atrium from the right ventricle does not develop well, and as a result, blood flows in the wrong direction in the **heart** and the right ventricle is pumped less and the blood in it becomes smaller and smaller.. it reaches the lungs and causes bruising in the patient.... **Atrial septal defect** In atrial septal defect, there is a hole between the two collecting chambers of the heart (right and left atrium) and excess blood passes through this hole to the right side of the heart, causing it to stretch and enlarge and cause many problems for the heart in the long run... #### Read more: **Best Children's Doctors*.. **single ventricular defect** In monoventricular defect, only one of the pumping chambers develops well, which leads to death if not treated within a few weeks after birth. Of course, today, complex heart surgeries are performed to increase the life span of affected **children**, but the patient's symptoms do not disappear.... Two types of defects: single ventricle: Left heart hypoplastic syndrome Hypoplastic **heart** syndrome is a rare type of congenital heart disease in which the left side of the heart is not well developed and is very small....this condition causes the body to not receive enough oxygen-rich blood....ventricular septal defect Ventricular septal defect is a common form of congenital heart disease.. This disease occurs when there is a cavity between the two pumping cavities of the heart (right and left ventricle).. Due to the pressure between the two ventricles, extra blood flows from the left ventricle to the right side in this cavity, causing an increase in blood pressure to the left.. Chamber... Small cavities often end up... fixed but larger holes must be surgically closed... #### Read more: **Best Doctors Children of Tehran** **displacement of large vessels** This **congenital** defect is rare and dangerous.... In displacement of the great arteries, the aortic and pulmonary valves and the arteries connected to them (pulmonary artery and aortic artery) are displaced and connected to the improper pumping chamber, causing improper pumping of blood throughout the body **** In tricuspid atresia, the tricuspid **heart** valve does not form properly.. This valve separates the right collecting chamber (right atrium) from the right pumping chamber (right ventricle). **repair of aortic stenosis** Aortic stenosis occurs when a part of the aorta narrows. Aortic stenosis causes problems with blood flow to the lower limbs. Over time, problems such as high blood pressure develop. To repair aortic stenosis, a type of congenital heart disease surgery is performed in which an incision is made on the left side or several grooves on the rib. Stenosis.. #### Read more: **List of Best Pediatricians** The common way to treat this disease is **surgery** in that narrow area where the heart is cut and connected to a larger vein. The second method for the treatment of aortic stenosis. The narrow part is removed and the remaining parts are stitched together... This procedure is often performed in older **children**... The third method for this type of surgery is the subclavian flap... First, an incision is made in the narrow part of the aorta, and then a patch is taken from the left subclavian artery to enlarge the narrow part of the artery. The pipe flows. In fact, it bypasses the narrow part of the aorta.. The atrial septum is a wall between the right and left atrium of the heart... In this wall of the atrial septum there is a hole where blood with or without oxygen can mix and cause medical problems and arrhythmia over time.. In some cases, this defect is fixed with open heart surgery... **Children**, the surgeon makes a small incision in the groin; A wire enters the blood vessel to reach the heart. In the next stage of surgery for congenital heart diseases, umbrella-like sliding devices are placed on both sides of the septum. These devices are attached to each other, thereby closing the hole in the wall... In an open **heart**, another surgery is to fix the atrial septum with another way to fix the atrial wall. The cavity of the heart is the use of one piece, the other blood vessel is in the form of a patch.. Tehran, the best pediatrician, the best pediatrician, Tehran, pediatrician, pediatrician
