Referral guidelines and recommendations

1. Preexisting cardiovascular conditions

Individuals with preexisting cardiovascular conditions such as congenital heart disease, valvular heart disease, cardiomyopathy, arrhythmias, diseases of the aorta, inherited disorders such as Marfan Syndrome, etc., should be referred to a cardio-obstetrics clinic. These conditions may require close monitoring and specialized management during pregnancy.

2. History of cardiac surgery or interventions

Patients with a history of prior cardiac surgery such as heart valve replacement or repair, coronary artery bypass grafting, or cardiac device implantation (e.g., pacemaker or defibrillator), may need specialized care to ensure the stability of their cardiovascular status during pregnancy.

3. Severe hypertension

Pregnant individuals with severe hypertension (blood pressure consistently ≥ 160/100 mm Hg) may benefit from evaluation by both an MFM specialist and a cardiologist. Uncontrolled hypertension during pregnancy poses significant risks and requires close monitoring and management.

4. Medication management

Pregnant or preconception individuals who require cardiovascular medications for preexisting conditions should be referred to assess the safety and efficacy of these medications during pregnancy. Adjustments or alternative medications may be needed.

5. Significant cardiac symptoms

Patients experiencing significant cardiac symptoms during pregnancy such as chest pain, palpitations, shortness of breath or syncope (fainting) should be promptly evaluated by both an MFM specialist and a cardiologist to determine the underlying cause and appropriate management.

6. Individualized assessment

Referrals should also be based on individualized assessment, considering the unique medical history and risk factors of each patient. Obstetricians should use their clinical judgment to determine when multidisciplinary care is necessary.

Frequently asked questions (FAQs)

For example, should the MFM’s referral come first, so the MFM coordinates with the cardiologist? Are there particular images or labs that should accompany a cardio-obstetrics referral?

The obstetrician should take a thorough cardiovascular and obstetrical history and assess potential risk factors for poor cardiovascular health. Such pertinent history may include a history of arrhythmia, cardiovascular surgery, hypertension, diabetes, dyslipidemia or obesity. If there are multiple concerns or a previous history of preeclampsia or hypertension, the obstetrician should consult an MFM specialist and cardiologist together. Providers can order a prepregnancy lipid panel and hemoglobin A1C for patients they are referring.

Team-based, value-based, patient-centered care is a collaborative approach that is designed to help patients and their families set expectations and develop a plan, which is then carried out throughout the pregnancy. This approach involves a team of healthcare professionals, which may include some or all of the following: a cardiologist, adult congenital heart disease specialist, intensivist, heart failure specialist, genetics specialist, electrophysiologist, OB-GYN, MFM specialist and obstetric anesthesiologist. All team members work together to care for higher-risk pregnancy patients. The team provides care and support to help patients through the pregnancy and postpartum period. Effective communication among team members is an essential part of this approach.

For pregnant individuals who do not require a referral to a cardiologist or MFM specialist, there are several general recommendations to optimize cardiovascular health during pregnancy. These recommendations are based on the American Heart Association's (AHA) Life's Essential 8 principles, encompassing essential aspects of heart health.

Patients should meet with cardiologists and specialists. They should be taking hypertension medications and may need to have tests for the heart such as an echocardiogram, stress test, ECG and Holter monitors (outpatient heart rhythm monitoring). Patients and their providers should discuss the likelihood that pregnancy will complicate these findings.

 

Obstetricians should be aware of the American College of Cardiology/AHA care pathways for the management of acute myocardial infarction, atrial fibrillation, cardiogenic shock, acute decompensated heart failure and maternal stroke. They should consult with cardiologists as well as the MFM and neurology teams.
