Study Notes
Coarctation of the Aorta
- The left ventricle has to work harder in coarctation of the aorta due to the obstruction of blood flow.
Effects on Body Systems
- The circulatory system is impaired due to the lack of space caused by coarctation of the aorta.
Effects on the Heart
- The heart muscles (left ventricle) become thicker and stronger in coarctation of the aorta to pump blood through the narrowed aorta.
Blood Pressure
- Blood pressure increases in the upper body in coarctation of the aorta due to the obstruction of blood flow.
Effects on Lower Extremities
- Blood flow to the lower extremities is decreased in coarctation of the aorta, leading to cold feet, weakness, and cramping.
