Heart valves and blood vessels play a crucial role in keeping circulation moving smoothly — and when they fail, the results can be life-threatening. In this lesson, we’ll review the function of cardiac valves, common terminology, and the different types of valve replacements used in patient care. We’ll also dive into aneurysms, starting with an overview of aortic anatomy, then breaking down thoracic (TAA), abdominal (AAA), and dissecting (DAA) aneurysms. Finally, we’ll connect it all to treatment options and the critical nursing considerations for these conditions.
