Pregnancy is one of the biggest physical challenges the heart ever faces. For most women, it passes without difficulty. For women with an existing heart condition, it can be entirely safe, but only with planning. The single most important step is to involve a cardiologist before pregnancy, not after.
What pregnancy does to the heart
By the middle of pregnancy, the blood volume in the body rises by around 40 to 50 per cent, and the heart pumps considerably more blood each minute. Hence, heart rate increases. Labour and delivery bring sudden shifts in blood pressure and fluid, and the first days after birth add another period of strain. A healthy heart can adapt. A heart with a structural or rhythm problem may struggle.
Which conditions need specialist planning?
Congenital heart disease is the most common heart condition in pregnant women in many countries, because most children born with heart defects now survive into adulthood. Some conditions, such as a small repaired hole between chambers, carry little extra risk. Others, such as complex repaired defects, need close monitoring.
Other conditions that need planning include heart valve disease (including rheumatic valve disease), cardiomyopathy, heart rhythm disorders, a previous heart attack, an artificial heart valve, and inherited conditions affecting the aorta, such as Marfan syndrome.
A small number of conditions, including severe pulmonary hypertension, carry such high risk that pregnancy is generally advised against.
What does pre-pregnancy planning involve?
A cardiologist will assess your heart using tests such as an echocardiogram and, if needed, a cardiac MRI or exercise test. They will use established guidelines to assess the risks and explain what they mean for you.
Medicines are a major part of the conversation. Some heart medicines, including certain blood pressure tablets and the blood thinner warfarin, can harm a developing baby and may need to be changed before conception. Women with mechanical heart valves need careful anticoagulation planning throughout pregnancy.
There is also the question of inheritance. Some congenital and genetic heart conditions can be passed on, and a fetal echocardiogram during pregnancy may be recommended to check the baby’s heart.
Joint care during pregnancy
For women with significant heart disease, care is usually shared between a cardiologist, an obstetrician experienced in high-risk pregnancy and an anaesthetist. Together they agree how often to monitor, the safest timing and method of delivery, the plan for pain relief and the level of monitoring needed after birth. Most women with heart disease can deliver vaginally; a caesarean is not automatically required.
Warning signs during pregnancy
Some breathlessness and ankle swelling are normal in pregnancy. Seek urgent advice for breathlessness that is getting rapidly worse or occurs at rest, chest pain, palpitations with dizziness or fainting, or coughing up blood.
After the birth
The heart continues to adjust in the weeks after childbirth as fluid levels and hormone levels change. Women with existing heart disease may need closer monitoring during this time. Peripartum cardiomyopathy, a rare condition that weakens the heart muscle, can develop towards the end of pregnancy or in the months after delivery.
Breathlessness and swelling may be mistaken for normal postnatal changes, so these symptoms should not be ignored. Before leaving hospital, women should discuss how their heart medicines may affect breastfeeding and choose suitable contraception. Any plans for another pregnancy should be reviewed with their cardiologist.
Why multispeciality care matters here
Pregnancy with heart disease is a clear example of why specialities need to work together. Families comparing options for a top multispeciality hospital in Dubai should ask whether cardiology, high-risk obstetrics, anaesthesia and neonatal care work as a single team, rather than separately.
Where is joint cardiac and pregnancy care available in Dubai?
Aster Hospitals, a hospital group with hospitals in Mankhool, Al Qusais and Muhaisnah and Aster Cedars Hospital & Clinic in Jebel Ali, runs an adult congenital cardiology service in which pregnancy is planned jointly with its maternity team, supported by cardiac MRI and 3D echocardiography.
People searching for the best adult congenital cardiology hospital will find that service described in full. Aster Hospital Mankhool was ranked 2nd in the UAE for both cardiology and obstetrics and gynaecology in Newsweek’s World’s Best Specialised Hospitals 2027, powered by Statista.
Having a poor heart condition does not automatically mean you cannot have a baby. What matters is knowing the risks before conception and having the right specialists involved from the start.
A cardiologist and obstetrician can help you prepare for pregnancy, manage your medicines and plan for delivery and recovery. Early advice gives you time to make evidence-based decisions on your health and your baby’s wellbeing.
