Mitral valve prolapse during pregnancy
Mitral valve prolapse (MVP) and pregnancy can be an unfavorable combination, especially when there are symptoms of prolapse and complications, such as mitral regurgitation. Yet most often in women with MVP, pregnancy, which ends in the birth of a healthy child, is completely normal.
Only a small percentage of women have problems with mitral valve loss and mitral valve regurgitation.
However, there are no two women or identical pregnancies, and disorders associated with heart valves do increase the likelihood of problem symptoms and complications. Therefore, it is extremely important to be careful when considering mitral valve prolapse on the background of developing pregnancy.

Effect of mitral valve prolapse on pregnancy
Most women with mitral valve prolapse tolerate pregnancy well. Sometimes women with MVP often find that the symptoms of the disease decrease in frequency and severity during pregnancy. Even women with severe mitral regurgitation can have a safe, successful pregnancy if there are no other cardiovascular problems.
During pregnancy, various physiological changes occur in the body:
- Blood volume increases (up to 50%).
- Blood vessels dilate.
- Blood pressure drops.
- There is a decrease in systemic vascular resistance.
- Cardiac output increases.
These cardiovascular changes can significantly improve the symptoms of PMK and cause a decrease in the severity of mitral regurgitation.
Yet, not all women experience a problem-free pregnancy with mitral valve prolapse and regurgitation. PMK can adversely affect the course of pregnancy, causing or worsening symptoms. In particular, it may occur:
Such signs are often possible symptoms of pregnancy with PMK. When mitral regurgitation may develop complications such as heart failure, arrhythmia and endocarditis.
Mitral valve prolapse during labor
Women with mitral valve prolapse usually do not experience problems during labor. However, before pregnancy, it is advisable to contact a cardiologist and get quality antenatal care. In cases of severe prolapse, significant mitral regurgitation, and / or systolic dysfunction of the left ventricle, careful planning of labor should be carried out, which often take place with the help of a multidisciplinary medical team.
Medical professionals usually recommend vaginal delivery when a mitral valve comes in and pregnancy occurs. Pain and symptoms such as palpitations are treated as needed during childbirth.
If there is significant mitral regurgitation and poor heart function, or if the symptoms of MVP can potentially cause complications, doctors can prescribe an epidural anesthesia.
Straining during labor causes the heart to work harder. Epidural anesthesia reduces the load on the heart, reducing the response to pain, stress and the need to push the baby. Since epidural anesthesia makes pushing difficult, vacuum extraction or forceps may be required. In extreme cases, a caesarean section. Also, doctors can prescribe antibiotics before delivery to women at high risk of infective endocarditis.

Effect of mitral valve prolapse on a child
If complications do not develop during pregnancy or during childbirth, MVP and mitral valve regurgitation, as a rule, do not pose any threat to the fetus. In some cases, heart valve disorders can affect the fetus, and, according to some studies, women with MVP are at risk for preterm labor. They are also more likely to have low birth weight babies.
Additionally, it is important to point out that women with mitral valve prolapse are more likely to have children with the same disease.
Is mitral valve prolapse a hereditary disease? Yes, most often PMH has a strong hereditary tendency. The good news is that most babies born with prolapse do not experience the symptoms or complications of this disease.
Mitral valve prolapse in children rarely causes health problems. Most often, many people live, completely unaware that their mitral valve is broken. However, patients with MVP should monitor and monitor their condition. Parents should monitor the symptoms of mitral prolapse and ensure that a sick child regularly undergoes medical examinations, as mitral valve disease may progress with time.
Mitral valve prolapse after pregnancy
PMK can sometimes worsen after pregnancy. As a result of the stress that pregnancy imposes on the body, clinics may occur in women with asymptomatic mitral valve prolapse. Those who have signs of the disease may experience an increase in the frequency and intensity of symptoms of MVP after childbirth. This may be accompanied by complications or proceed without them.
In most cases, cardiac complications after pregnancy develop only in cases of severe MVP and in those who have mitral valve regurgitation.
In general, mitral valve prolapse with regurgitation and pregnancy increases the risk of a woman feeling worse.However, most patients do not experience health problems after pregnancy due to heart valve disease. Otherwise, suitable treatment options for the affected heart valve are used.
Problems after pregnancy due to MVP with (or without) regurgitation are most often caused by the following:
- A woman is 30 years old and older.
- The woman suffered several pregnancies.
- The woman had more than one fruit.
Women with ventricular dysfunction and preeclampsia (a serious disorder caused by pregnancy, accompanied by high blood pressure) are also usually at a higher risk for the progression of MVP.
General recommendations for pregnant women with mitral valve prolapse
For safety reasons, women with PMH should receive proper care before and during pregnancy.
A healthy diet is one way to reduce the risks associated with pregnancy and the state of the mitral valve.
In fact, the exclusion of certain foods that should be avoided with mitral valve prolapse can prevent the worsening of symptoms and complications. It is also important to have enough rest and avoid stressful situations.
In addition to conventional medications that should not be taken in patients with mitral valve prolapse, some of the drugs commonly used to treat PMH and mitral regurgitation may be unsafe during pregnancy. These include antiarrhythmic drugs, ACE inhibitors and beta-blockers, and aldosterone antagonists . Vasodilators and anticoagulants, such as warfarin for mitral valve prolapse and pregnancy, can also be harmful in some cases.
The risk of mortality is high for the mother and fetus with severe heart valve disorders and dysfunction. For this reason, medical professionals recommend that women with such diseases avoid pregnancy. Patients with mild PMK / valvular disease and normal cardiac performance are usually not contraindicated. In such cases, it is important to consult a midwife, a cardiologist and an obstetric anesthesiologist in a timely manner.
