Cardiopulmonary bypass in pregnancy

Area of Science:

• Cardiology
• Obstetrics
• Cardiopulmonary Bypass

Background:

• Cardiac surgery during pregnancy poses risks, particularly for the neonate.
• Cardiopulmonary bypass (CPB) is a significant factor in adverse maternal and fetal outcomes.
• CPB can lead to utero-placental hypoperfusion, impacting fetal cardiac output and oxygenation.

Purpose of the Study:

• To review the outcomes of cardiac surgery performed on cardiopulmonary bypass (CPB) during pregnancy.
• To identify strategies for improving maternal and fetal outcomes in this high-risk population.

Main Methods:

• Review of existing literature on cardiac surgery in pregnant women undergoing CPB.
• Analysis of factors contributing to adverse outcomes.
• Identification of potential interventions and management strategies.

Main Results:

• Maternal outcomes are comparable to non-pregnant patients undergoing similar surgery.
• Neonatal outcomes are frequently poor, largely due to CPB effects.
• CPB-related issues include utero-placental hypoperfusion, reduced fetal cardiac output, and hypoxia.

Conclusions:

• Early pre-operative optimization of maternal cardiovascular status is crucial.
• Perioperative fetal monitoring and CPB optimization are essential.
• Elective surgery in the second trimester, potentially after fetal delivery, may improve outcomes.
