Which predominantly female valvular disorder is thought to have an autosomal dominant inheritance pattern?

• A. tricuspid valve prolapse
• B. tricuspid prolapse
• C. mitral valve prolapse
• D. aortic stenosis

Answer: (C)

Mitral valve prolapse is predominantly observed in females and is associated with an autosomal dominant inheritance pattern. This condition occurs when the mitral valve does not close properly during heart contraction, allowing blood to leak backward into the left atrium. Genetic studies have identified various connective tissue disorders, such as Marfan syndrome, which also demonstrate an autosomal dominant inheritance pattern and are frequently associated with mitral valve prolapse. This association provides a genetic and familial aspect to the condition, supporting the understanding that mitral valve prolapse can run in families and is more common in females due to hormonal and anatomical factors. Therefore, identifying mitral valve prolapse as the correct answer highlights the key characteristics of this valvular disorder.
