Because valvular heart disease can cause the heart to work harder, enlarge, and ultimately lead to congestive heart failure, symptoms like shortness of breath, fatigue, fainting, chest pain, and ankle swelling may appear as the disease progresses.
The pulmonary valve controls the flow of blood from the heart to the lungs, and the aortic valve governs blood flow between the heart and the aorta, and thereby the blood vessels to the rest of the body. The mitral and aortic valves are the ones most frequently affected by valvular heart disease. High blood pressure and atherosclerosis may damage the aortic valve. 2  A heart attack may damage the muscles that control the heart valves. 3  Other disorders such as carcinoid tumors, rheumatoid arthritis, systemic lupus erythematosus, or syphilis may damage one or more heart valves.
