Which of the following conditions is in the intermediate risk category?

Mild mitral valve stenosis is categorized within the intermediate risk group mainly due to its hemodynamic implications and the potential for complications during pregnancy and labor. While it may not pose as significant a risk as severe valvular heart diseases or conditions like pulmonary arterial hypertension, it still requires careful monitoring and management due to the possibility of worsening symptoms or heart failure in the setting of increased blood volume and changes in cardiac output that occur during pregnancy.

Mild mitral valve stenosis typically does not significantly obstruct blood flow or lead to severe complications, which is why it is distinguished from high-risk conditions. However, it carries more risk than conditions considered low risk, such as well-managed congenital heart disease (e.g., minor ASD). Thus, it is important for obstetricians and gynecologists to be aware of the factors associated with mild mitral valve stenosis, ensuring appropriate management strategies to mitigate risks during pregnancy.
