The following are 5 common congenital heart diseases with good treatment results, such as ventricular septal defect, atrial septal defect, patent ductus arteriosus, bilobed aortic valve and aortic constriction. One of the congenital heart diseases with good treatment results: ventricular septal defect Hong Hao, Department of Cardiac Surgery, Wuhan Union Hospital Ventricular septal defect refers to the presence of abnormal openings in the left and right ventricular septum, which can be located at any position of the septum, and is therefore divided into different anatomical types, with septal defects of different diameters and single or multiple occurrences. It is the most common congenital disease in childhood and accounts for 10% of all adult congenital diseases. Due to advances in medical technology, patients who used to die from infective endocarditis and heart failure have been able to survive into adulthood but septal defects older than 40 years of age are rare. The second congenital heart disease with good treatment results: atrial septal defect Atrial septal defect is an abnormal direct opening between the left and right atria. It is the most common type of congenital heart disease in adults, accounting for about 1/4. It is mostly of the secondary hole type (65%-75%), while the primary hole type accounts for only 15%-20% and the others account for 5%-10%. Patients with atrial septal defect without severe pulmonary hypertension or Eisenmenger’s syndrome can undergo atrial septal defect repair. The success rate and cure rate is very high according to the overall situation of this type of surgical treatment in China. The third congenital heart disease with very good treatment effect: arteriovenous ductus arteriosus is less common in adults abroad, and it is mostly treated by radical surgery in pediatrics, accounting for only 2% of adult precocious heart disease, which is ranked 10th. According to the literature, 16.7% of adults over 18 years of age still have preexisting heart disease in China, accounting for the third place, mostly in women. There are still more cases that require further diagnosis and treatment. The arterial duct is made of normal embryonic tissue and originates from the sixth aortic arch. It is located between the main pulmonary artery and the descending aorta. Its origin and course vary widely. The typical ductus arteriosus is located between the bifurcation of the main pulmonary artery and the left pulmonary artery and the descending aorta (just distal to the origin of the left subclavian artery); the ductal morphology is conical, i.e., wide at the aortic end and small at the pulmonary end, columnar, and windowed. The main pathophysiological changes are left-to-right shunting at the arterial level, increased pulmonary venous return to the left atrium and left ventricle, resulting in an increased volume load on the left atrium and left ventricle, which increases the cardiac output of the left ventricle and increases the aortic systolic pressure; some of the blood flow is then shunted to the pulmonary artery through the unclosed duct. When the left ventricle is diastolic, the aortic diastolic pressure is higher than the pulmonary artery diastolic pressure, so part of the blood continues to flow from the aorta to the pulmonary artery via the catheter, causing the diastolic pressure to decrease and the pulse pressure difference to increase, forming a peripheral vascular sign. Congenital heart disease with good treatment effect No. 4: Bilobed aortic valve Bilobed aortic valve is one of the very common congenital malformations with a prevalence of 1-2% in the population. The valve malformation can cause turbulence, which results in calcification and degeneration of the aortic valve. This is usually associated with incomplete aortic valve closure, and aortic stenosis is also a common complication of congenital diastolic aortic valve. Congenital heart disease with good treatment outcome #5: Aortic constriction usually occurs due to the elevation of the luminal crest-like tissue at the location of the distal left subclavian artery and the arterial ligament, forming a “shelf” and resulting in aortic constriction, and in some cases, the location of the constriction is often proximal to the left subclavian artery. There is an increase in blood pressure proximal to the constriction, including the upper extremity and head circulation, in addition to extensive collateral circulation between the intrathoracic, intercostal, and subclavian arteries. Note that aortic constriction often coexists with a mitral aortic valve.
