TRICUSPID ATRESIA A congenital heart defect in which the valve between the R atrium and R ventricle fail to develop → resulting in no opening to allow blood to flow from the R atrium to the R ventricle, and through the pulm artery into the lungs Bood returning from the systemic circulation to the R atrium cannot enter the R ventricle d/t agenesis of the tricuspid valce. Deoxygenated blood passes through the atrial septum into the L atrium – it never enters the pulmonary vasculature Oxygenated blood mixes w deoxygenated→ and then travels to the lungs ASSESSMENT: Consider hx since birth Cyanosis at birth or a few days later when the ductus arteriosus closes Rapid respirations Difficulty feeding Cyanosis/pale gray color Overactivity of the apical HR Sucking strength (usually poor) Crackles/wheezes Murmurs Cool or clammy skin in extremities Clubbing – in older infants * LABS/DX: CBC- to check H/H, erythrocytes → can indicated development of polycythemia Pulse ox/ABGS – determine oxygen saturation levels Echocardiography- reveals absence of tricuspid valve or underdeveloped R ventricle EKG- can indicate HF Cardiac catherization- to check for extent of structure defects
