Which condition is classified under mWHO Risk Class II?

The condition classified under mWHO Risk Class II is repaired Tetralogy of Fallot. This classification is used to categorize the risk of maternal morbidity during pregnancy in women with pre-existing heart conditions.

Repaired Tetralogy of Fallot generally has a good prognosis for most women, especially when the surgical repair has been successful and there are no significant residual defects. Women in this category typically have functional capacity of Class I or II according to the New York Heart Association (NYHA) classification, meaning they can engage in ordinary physical activity without undue fatigue, palpitations, or shortness of breath.

In contrast, severe mitral valve stenosis and unrepaired cyanotic heart disease both represent higher-risk conditions requiring closer monitoring during pregnancy due to the increased likelihood of complications. Pregnancy with severe pulmonary hypertension is particularly concerning and classified as a higher risk due to the significant strain it places on the cardiovascular system, which can lead to adverse outcomes for both the mother and the fetus.

Thus, repaired Tetralogy of Fallot sits comfortably within mWHO Risk Class II as it is associated with relatively lower risk, highlighting the importance of successful surgical intervention and regular follow-up in managing congenital heart defects during pregnancy.
