I30-I52: Other forms of heart disease
I34: Nonrheumatic mitral valve disorders
Nonrheumatic mitral valve disorders are a group of conditions that affect the mitral valve in the heart, which controls blood flow from the left atrium to the left ventricle. These disorders are not caused by rheumatic fever, a disease that can develop from strep throat. These conditions might be present at birth (congenital) or develop later in life due to valve wear. Nonrheumatic mitral valve disorders can lead to improper functioning of the valve, such as problems with the valve not closing correctly, which might enable the blood to flow backward into the atrium (known as mitral valve insufficiency or regurgitation) or the valve becoming narrowed, restricting the blood flow (known as mitral valve stenosis). Symptoms may include fatigue, shortness of breath, rapid heartbeat palpitations, and chest pain. Over time, these disorders can develop into more serious conditions, including heart failure.
