Hypertrophic cardiomyopathy and pregnancy

Area of Science:

• Cardiology
• Maternal-Fetal Medicine
• Genetics

Background:

• Women with pre-existing cardiomyopathies have limited cardiovascular reserve.
• Pregnancy, labor, and delivery present unique hemodynamic challenges, increasing risks for heart failure, arrhythmias, and maternal mortality in this population.
• Hypertrophic cardiomyopathy (HCM) is a significant concern during pregnancy.

Purpose of the Study:

• To review the hemodynamic stressors of pregnancy in women with hypertrophic cardiomyopathy.
• To discuss risk assessment strategies for pregnant patients with HCM.
• To examine existing evidence on the management of HCM during pregnancy, labor, and delivery.

Main Methods:

• Literature review of hemodynamic changes during pregnancy.
• Analysis of risk stratification tools for cardiovascular conditions in pregnancy.
• Synthesis of current management guidelines for hypertrophic cardiomyopathy in expectant mothers.

Main Results:

• Pregnancy significantly increases cardiac workload, posing risks for decompensation in women with HCM.
• Preconception counseling and risk assessment are critical for informed decision-making.
• Multidisciplinary team management and controlled delivery are essential for optimal outcomes.

Conclusions:

• Managing hypertrophic cardiomyopathy during pregnancy requires a proactive, individualized approach.
• Careful monitoring and planning are necessary to mitigate risks associated with pregnancy in women with HCM.
• Further research is needed to optimize management strategies and long-term outcomes.
