10 Heart Conditions That Present Differently in Women

8. Valvular Heart Disease - The Hormonal and Anatomical Influences

Valvular heart disease in women presents unique challenges related to anatomical differences, hormonal influences, and specific conditions that disproportionately affect female patients. Women have smaller cardiac structures overall, including smaller valve annuli, which can complicate surgical interventions and influence the choice of prosthetic valves. Mitral valve prolapse, a condition where the valve leaflets bulge back into the left atrium during contraction, affects women three times more often than men and is often associated with symptoms of chest pain, palpitations, and anxiety that may be mistakenly attributed to psychological causes rather than recognized as cardiac pathology. Rheumatic heart disease, while declining in developed countries, still affects women disproportionately in many parts of the world and can lead to severe mitral and aortic valve stenosis that may not become symptomatic until pregnancy when increased cardiac demands unmask the underlying pathology. Pregnancy itself creates unique challenges for women with valvular disease, as the physiological changes of pregnancy – including increased blood volume, heart rate, and cardiac output – can exacerbate symptoms and lead to complications in women with previously well-tolerated valve abnormalities. Aortic stenosis in women often presents later in life and may progress more rapidly once symptoms develop, yet women are less likely to be referred for valve replacement surgery and more likely to experience delays in treatment. The symptoms of valvular disease in women, including fatigue, shortness of breath, and exercise intolerance, are often subtle and may be attributed to aging or deconditioning rather than recognized as signs of significant cardiac pathology requiring intervention.
