Cardiopulmonary bypass
Study Notes
Heart Defects and Treatment
- Incomplete fusion of the endocardial cushions results in Atrioventricular Canal Defect (AVCD)
- Infants with severe symptoms of AVCD are managed with aggressive medical therapy, including cardiotonic agents, diuretics, and correction of acid-base imbalance
- Patients with Patent Ductus Arteriosus (PDA) exhibit a continuous machinery-like murmur on auscultation
- Indomethacin is administered to premature infants with PDA to close the defect
- Complete AVCDs are often surgically repaired using the Two-Patch Method
Test your knowledge on cardiac defects causing increased pulmonary blood flow, focusing on atrioventricular canal defect and patent ductus arteriosus. Learn about the management options for these defects.
