Surgical treatment of complete endocardial cushion defects in infants and children Abstract: Objective To explore the surgical methods and complications prevention and treatment of endocardial cushion defects in infants and…
Endocardial cushion defects are a rare form of severe congenital heart disease. The endocardial cushion is an embryonic connective tissue involved in the formation of the interatrial septum, the interior…
Complete endocardial cushion defects Type A are commonly treated with surgical repair of the defective deformity. Endocardial cushion defects, also known as atrioventricular septal defects or atrioventricular channel defects, are…
Surgical complications 1. Atrioventricular block. If permanent, a pacemaker needs to be implanted. 2.Low cardiac output syndrome. It is the most serious postoperative complication that endangers the patient’s life. 3. Residual shunt…
Timing of surgery Partial endocardial cushion defects are usually operated on between the ages of 2 and 4 years. Earlier surgery is indicated if there is significant mitral regurgitation or…
Endocardial cushion defects are classified as partial, excessive, or complete according to the degree of development of the atrial septal tissue around the atrioventricular valve and the atrioventricular valve malformation. 1.Partial…
Partial Patients with small shunts can be asymptomatic, with only a heart murmur detected on physical examination. In patients with larger shunts, as pulmonary vascular resistance decreases after birth, patients…
Definition of complete endocardial cushion defect. A group of cardiac malformations caused by abnormal endocardial cushion development, characterized morphologically by the absence of the atrioventricular septum and the presence of only…
