Heart Issues Around Birth (Peripartum Cardiomyopathy)
The short answer
Peripartum cardiomyopathy (PPCM) is a rare but serious form of heart failure that can develop in the last month of pregnancy or up to 5 months after delivery. It occurs in approximately 1 in 1,000-4,000 pregnancies. Early recognition and treatment are critical, as most people recover with proper medical care.
Parents everywhere have the same worry. You are doing the right thing by looking into it.
By Age
What to expect by age
PPCM typically presents in the last month of pregnancy. Symptoms include shortness of breath (beyond normal pregnancy breathlessness), persistent cough, swelling in the legs and feet, rapid weight gain from fluid retention, and palpitations. Because these symptoms overlap with normal pregnancy, PPCM can be missed. If breathlessness is severe, progressive, or occurs while lying flat, seek evaluation.
PPCM most commonly presents in the first month after delivery. Symptoms include extreme fatigue, inability to lie flat without breathing difficulty, persistent cough, swelling, and rapid heartbeat. Risk factors include age over 30, multiple pregnancies, African American descent, and preeclampsia history. With treatment (heart failure medications), about half of people fully recover heart function.
What Should You Do?
When to take action
- Mild shortness of breath with exertion in late pregnancy
- Mild ankle swelling that improves with elevation
- Occasional palpitations lasting seconds
- Shortness of breath that is worsening or more severe than expected for your stage of pregnancy
- Swelling that is rapid or does not improve with rest
- Heart palpitations that are frequent or prolonged
- Severe shortness of breath, especially when lying down or at rest
- Chest pain with breathing difficulty
- Persistent rapid heartbeat with dizziness or fainting
- Coughing up frothy or pink-tinged sputum

Heart Problems After Birth (Postpartum Cardiomyopathy)
Postpartum cardiomyopathy (PPCM) is a rare but serious form of heart failure that develops in the last month of pregnancy or up to 5 months after delivery. It occurs in approximately 1 in 1,000-4,000 deliveries. Symptoms include severe shortness of breath, persistent swelling, rapid heartbeat, and extreme fatigue beyond normal postpartum tiredness. Early diagnosis and treatment are crucial - most people respond well to heart failure medications.
Breathing Difficulty in Pregnancy
Shortness of breath affects up to 75% of pregnant people. It is caused by hormonal changes (progesterone increases respiratory drive), increased oxygen demand, and the growing uterus pushing the diaphragm upward. While usually normal, sudden or severe breathlessness should be evaluated promptly.
Dealing with Abnormal Prenatal Screening Results
An abnormal prenatal screening result can be terrifying, but it is important to understand that screening tests are designed to cast a wide net and have significant false-positive rates. Most people with abnormal screening results go on to have healthy babies after further testing confirms the baby is fine. An abnormal screening is a reason for more information, not a diagnosis.
Pregnancy Over 35 (Advanced Maternal Age)
While pregnancy after 35 carries some increased risks (including chromosomal abnormalities, gestational diabetes, and hypertension), the vast majority of people over 35 have healthy pregnancies and healthy babies. The term "geriatric pregnancy" is outdated and does not reflect reality. With appropriate prenatal care and monitoring, outcomes are excellent.
Amniocentesis Questions and Fears
Amniocentesis is a diagnostic test performed between 15-20 weeks that analyzes amniotic fluid to detect chromosomal conditions and genetic disorders with over 99% accuracy. The risk of pregnancy loss from the procedure is approximately 1 in 500-1,000 when performed by an experienced provider. Understanding the actual risks can help you make an informed decision.
20-Week Anatomy Scan Unexpected Findings
The 20-week anatomy scan checks your baby's major organs, structures, and growth. Most scans are completely normal. When unexpected findings are identified, they range from minor variants that resolve on their own to conditions that need further evaluation. Many findings require nothing more than a follow-up ultrasound to confirm the baby is developing well.
