Congenital Heart Defects Questions with complete solution 2024 Aortic stenosis - correct answer This defect is the narrowing or stricture of the aortic valve, causing resistance to blood flow from the left ventricle into the aorta, resulting in decreased CO, left ventricular hypertrophy, and pulmonary vascular congestion Atrial Septal Defect (ASD) - correct answer An abnormal opening between the atria that causes increased flow of oxygenated blood into the right side of the heart. Atri...
