145. ACHD: Pregnancy and Congenital Heart Disease with Dr. Carole Warnes

Cardionerds: A Cardiology Podcast

CardioNerds (Amit Goyal and Daniel Ambinder), ACHD series co-chair Dr. Agnes Koczo (UPMC), and ACHD FIT lead Dr. Katia Bravo (UCLA) join ACHD expert Dr. Carole Warnes (Professor of Medicine and founder of the Adult Congenital Heart Disease Clinic at Mayo Clinic), to discuss adult congenial heart disease and pregnancy. They cover preconception counseling in women with congenital heart disease, appropriate risk stratification to estimate maternal and neonatal morbidity using existing tools and an individualized care approach and preparation for a multidisciplinary delivery plan. Audio editing by CardioNerds Academy Intern, Dr. Leticia Helms. The CardioNerds Adult Congenital Heart Disease (ACHD) series provides a comprehensive curriculum to dive deep into the labyrinthine world of congenital heart disease with the aim of empowering every CardioNerd to help improve the lives of people living with congenital heart disease. This series is multi-institutional collaborative project made possible by contributions of stellar fellow leads and expert faculty from several programs, led by series co-chairs, Dr. Josh Saef, Dr. Agnes Koczo, and Dr. Dan Clark. The CardioNerds Adult Congenital Heart Disease Series is developed in collaboration with the Adult Congenital Heart Association, The CHiP Network, and Heart University.

Pearls Women with congenital heart disease can safely carry a pregnancy if appropriate risk stratification and management is performed by an expert multidisciplinary cardio-obstetrics team.There are a myriad of hemodynamic and vascular changes which impact congenital cardiac physiology and evolve throughout the different stages of pregnancy. Therefore, planning is key. An evaluation of heart rate response to exercise and optimization of potential factors that could worsen during pregnancy, such as arrhythmias, are recommended.Maternal morbidity & mortality risk-stratification systems such as the modified WHO, CARPREG or ZAHARA criteria are helpful starting points. Ultimately, each patient requires individualization given the heterogeneity that exists among congenital heart defects.Vaginal delivery is generally preferred over C-section from a cardiac standpoint. An assisted second stage of labor during the period of greatest hemodynamics changes should also be considered if vaginal delivery is pursued.

Why is preconception counseling important in women with congenital heart disease and what does it entail? Ensuring women with congenital heart disease are optimized prior to conception decreases maternal and neonatal complications. For this reason, preconception counseling is paramount for these patients.In addition, counseling leads to patients making more informed decisions about family planning.The integral parts of preconception counseling include: (1) discussing the current anatomical and physiological status, (2) discussing possible complications during pregnancy specific to the patient's congenital heart defect (with genetic counseling referral if appropriate), (3) evaluating cardiac medications, taking into account benefits vs teratogenic potential, (4) discussing and planning for necessary pre-pregnancy tests or interventions (exercise stress testing is an important tool in evaluating how the patient will tolerate the stressors of pregnancy), (5) organizing antepartum care with high-risk obstetrics teams, (6) discussing location,
