Pregnancy and Heart Disease

Pregnancy increases stress on a woman’s heart and circulatory system, posing significant, sometimes life-threatening, risks for mothers and their babies. This includes women who have pre-existing heart conditions and those who develop conditions during pregnancy.

Changes to the heart and circulatory system during pregnancy include:

  • Increased blood volume
  • Increased amount of blood pumped by the heart
  • Increased heart rate
  • Lowered blood pressure

These factors lead to increased risks for heart rhythm abnormalitiesheart valve (artificial or natural) issues and congestive heart failure in pregnant mothers. Also, if a mother was born with a heart defect, her baby has an increased risk of developing a congenital heart defect.

Combining clinical and research expertise in cardiovascular disease and high-risk obstetrics, the Brigham and Women’s Hospital (BWH) Heart & Vascular Center cares for women with significant medical conditions who either are pregnant or would like to become pregnant.

Our specialists use a multidisciplinary approach to diagnose and treat women with arrhythmia, cardiomyopathycoronary artery disease, structural heart disease, vascular disease and other serious cardiovascular conditions. This includes care for women with pre-existing heart and vascular disease or for women who develop cardiovascular conditions during pregnancy. Experts from interventional cardiologycardiac surgeryadult congenital heart disease, vascular medicine, electrophysiology, high-risk obstetrics, prenatal genetics, infertility, reproductive surgery and other specialties collaborate to ensure that women are carefully evaluated and treated to address both their health and their child’s health.

Diagnosis of Heart Disease in Pregnancy

Cardiovascular specialists in the Complex Consultative Cardiology Program provide expert evaluation and diagnosis with the aid of the latest in advanced imaging technologies, including techniques that are safe for use during pregnancy. Along with a careful physical examination, the cardiologist may order one or more of the following tests or procedures, with some only used before a woman becomes pregnant:

Treatment for Heart Disease in Pregnancy

Whenever possible, cardiovascular issues are addressed prior to conception to manage existing conditions safely during pregnancy, including coordinating care with cardiac surgeons, interventional cardiologists and electrophysiologists. For women with congenital heart disease or other pre-existing cardiovascular conditions who are considering pregnancy, specialists may adjust medications and will communicate risks of pregnancy and the steps that you should take prior to conception.

Our specialists develop individualized treatment plans for patients based on:

  • Age
  • Expectations for course of the disease
  • Overall health
  • Medical history
  • Presence of other conditions
  • Severity and form of the disease
  • Tolerance for specific medications or procedures
  • Whether the patient is pregnant

Treatment, ranging from lifestyle changes to surgery, may include:
