What is the most common cardiac valve dysfunction seen in the United States?

Aortic valve stenosis is often identified as the most common cardiac valve dysfunction in the United States, particularly among older adults. This condition occurs when the aortic valve narrows, which restricts blood flow from the heart into the aorta and to the rest of the body. The increased pressure the heart must exert to pump blood through the narrowed valve can lead to a variety of symptoms, including chest pain, fatigue, and shortness of breath.

In the aging population, the prevalence of aortic valve stenosis has increased due to factors such as age-related calcification of the valve, which is a common degenerative process. It is especially significant in older individuals who may have other underlying risk factors like high blood pressure or high cholesterol. Therefore, understanding the dynamics of aortic valve stenosis helps healthcare providers recognize and manage this condition effectively, especially in populations at risk.

Although other valvular conditions exist, they tend to be less prevalent or are often secondary to other health issues. Aortic valve stenosis stands out due to its direct impact on the aging population and the consequences of untreated valve disorders. As a result, it is commonly encountered in clinical practice, reinforcing its position as a primary concern for cardiovascular health in the U.S
