I35: Nonrheumatic aortic valve disorders

Nonrheumatic aortic valve disorders are a group of conditions that affect the aortic valve in the heart, which is responsible for controlling the flow of blood out from the heart to the rest of the body. These disorders are nonrheumatic, meaning they're not caused by rheumatic fever, a condition that can result from untreated strep throat or scarlet fever. Symptoms and severity of these disorders can vary, but common signs often include chest pain, fatigue, lightheadedness, and shortness of breath especially during physical activity. Over time, these disorders can lead to complications such as heart failure, stroke, blood clots, and sudden cardiac arrest. The affected systems primarily include the cardiovascular system but it can indirectly impact other systems due to poor blood circulation. It's important to note that these disorders can develop for numerous reasons such as aging, infections, congenital heart defects, or damage to the heart muscle.
