A characteristic of mWHO Risk Class III is a significant risk for complications during pregnancy. This classification is part of the modified World Health Organization (mWHO) guidelines that assess the cardiovascular status of women with pre-existing heart conditions before and during pregnancy.

Women categorized as mWHO Risk Class III often have conditions that pose a moderate-to-high risk, which can lead to serious complications during pregnancy, such as heart failure or severe arrhythmias. These patients require careful monitoring and management due to the potential for increased morbidity.

Healthy cardiovascular status is not associated with mWHO Risk Class III, as this classification indicates a higher risk rather than a healthy state. Low risk for arrhythmias is also inconsistent with this classification, as women in this group may indeed have an increased likelihood of arrhythmic events. Furthermore, the presence of only mild physical impairments does not accurately reflect the overall risk profile of mWHO Risk Class III, which encompasses a broader range of serious cardiovascular issues that can affect pregnancy outcomes.
