Congenital Heart Disease and Reproductive Risk: An Overview for Obstetricians, Cardiologists, and Primary Care Providers

Sexual and Reproductive Health in Sickle Cell Disease: A Qualitative Analysis of Pediatric Hematologist Perspectives

PURPOSE

Significant progress in managing sickle cell disease (SCD) has led to improved mortality and a growing population of people living with SCD. Sexual and reproductive health (SRH) for individuals with SCD is a critical but under-addressed aspect of care. This study characterizes clinicians' current practices in SRH care for adolescents with SCD.

METHODS

In a cross-sectional qualitative study, we recruited clinicians who care for adolescents with SCD from a national professional listserv. Participants completed in-depth semistructured qualitative interviews over video conference from May 2022 to May 2023. The study involved 20 SCD providers (14 female and 6 male). Interviews explored the clinician's role, perceived barriers and facilitators, and recommendations for SRH care for adolescents with SCD.

RESULTS

Key concerns identified included managing vaso-occlusive events during menstruation, priapism, and contraceptive choice. Clinicians expressed different readiness for incorporating SRH care in their practice and identified barriers, such as training, time, and subspecialist availability. While all participants acknowledged the priority of SRH care for adolescents with SCD, clearly outlined guidelines are needed to enhance counseling and the provision of SRH care. Clinicians with specific expertise or familiarity with the patient are best suited to providing aspects of SRH care.

DISCUSSION

This study emphasizes clinician interest in comprehensive SRH care for individuals with SCD. Well-defined guidelines are necessary to aid clinicians in addressing the unique SRH needs in SCD. Further study is needed to understand patient attitudes and establish evidence-based guidelines for SRH in SCD.

Management of Fallot's Uncorrected Tetralogy in Adulthood: A Narrative Review

The majority of cyanotic congenital cardiac defects are caused by the tetralogy of Fallot. Some symptoms include a biventricular connection of the aortic root, right ventricular hypertrophy, blockage of the right ventricular outflow tract, and a ventricular septal defect. Our understanding of tetralogy of Fallot (TOF) has significantly advanced since it was first described in 1888, and early diagnosis has led to improved surgical management and increased life expectancy. Adults with unrepaired and repaired TOF present with a range of late complications, including heart failure, the need for re-interventions, and late arrhythmias. Right ventricular (RV) failure, often caused by chronic pulmonary regurgitation, is a significant cause of heart failure in patients with TOF. Current treatment options are limited, and mainstay surgical procedures such as pulmonary-valve replacement (PVR), trans-annular repair (TAR), or infundibular widening repair have not shown a significant reduction in preventing right ventricular (RV) failure or death. Here, we explain the mechanisms of RV failure in ToF, chronic pulmonary regurgitation, heart failure, and secondary polycythemia. HF management in untreated adults is discussed. The progression of the disease, as well as complications, are also discussed. The treatment plan and the need to investigate the best management approach for this unsolved problem are included. This review aims to fill the knowledge gaps and supply valuable information regarding mechanisms of RV failure, chronic pulmonary regurgitation, and secondary polycythemia. To summarize, a new combat strategy must be found to battle RVF, and a more profound vision of these mechanisms is required. If it is not corrected, it will be one of the future research lines that will contribute to designing more efficacious treatment techniques for adults with TOF.

Associations of Reproductive Health Concerns, Health-Related Quality of Life, and Stress Among Adolescents and Young Adults with Chronic Illness

OBJECTIVE

Adolescents and young adults (AYA) living with chronic illness are as sexually active and interested in having children as healthy peers. Few studies have examined the intersection of managing chronic illness and concerns about realizing reproductive goals, including fertility, pregnancy, childbirth, and parenting. Even less is understood regarding how these concerns might be associated with psychological distress. This study examines associations between the reproductive health concerns (RHC) and health-related stress of AYA patients living with chronic conditions including rheumatologic, cardiac, pulmonology, gastrointestinal disorders, and solid organ transplant.

METHODS

A total of 140 patients aged 15 to 20 years (68% female; 81% Hispanic/Latinx) recruited from a transition program located at a safety-net pediatric institution completed surveys examining multiple dimensions of RHC and health-related quality of life (life satisfaction, illness burden, and illness-related anxiety) and condition-related stress. Exploratory factor analyses of RHC variables yielded 3 factors used in regression analyses to identify convergent validity of RHC factors with health-related mental health measures.

RESULTS

Three RHC factor loadings emerged: concern about availability to raise children (timing/future), impact of condition/medication on fertility and childbearing (pregnancy/fertility), and impact of condition on motivation to have children (motivation/decision-making). Positive associations were found between all RHC factors and illness-related anxiety; condition-related stress was associated with motivation/decision-making.

CONCLUSION

RHC, health-related anxiety, and stress can impede healthy sexual and reproductive health and development of AYA living with chronic conditions. Providers' proactive exploration of patients' concerns about their reproductive future can offer critical support as they navigate the unique existential challenges of early adulthood.

Adolescent Women with Congenital Heart Disease: Self-Reported Reproductive Health Discussions with Health Care Providers

STUDY OBJECTIVE

This study evaluated self-reported discussions with health care providers (HCPs) among adolescent and young adult (AYA) women with congenital heart disease (CHD).

DESIGN

Data were collected through a one-time survey of AYA women.

SETTING

Participants were recruited from pediatric cardiology clinics.

PARTICIPANTS

AYA women with CHD, ages 14-21 (N = 107) INTERVENTIONS: None MAIN OUTCOME MEASURES: Questionnaires assessed adolescent characteristics and specific HCP discussions regarding transmissibility of a cardiac condition to the infant, risk of pregnancy, and hormonal contraception. Outcome measures were self-reported discussions with HCPs about these reproductive health topics.

RESULTS

Mean age was 16.8 years (SD = 2.1). Self-reported reproductive health discussions were infrequent, including discussions on transmissibility of a heart condition to their offspring (37%), risk of pregnancy to their offspring (34%), risks of pregnancy to their health (46%), and risks of hormonal contraception given their heart condition (21%). Reported discussions were most commonly with a cardiologist.

CONCLUSIONS

AYA women with CHD reported limited discussions about reproductive health topics important to those with CHD. Lack of appropriate and timely counseling could lead to poor maternal and child health outcomes. Targeted interventions that improve reproductive health discussions between HCPs and AYA women with CHD are needed to close critical information and service gaps.

Pregnancy Complications and Outcomes Among Women With Congenital Heart Disease in Beijing, China

Objective

To conduct a comparative analysis of the complications and outcomes in pregnant women with and without congenital heart disease (CHD) in Beijing, China.

Methods

We compared pregnancy-related complications and outcomes experienced by women with and without CHD throughout 19,424 deliveries in Beijing Anzhen Hospital between 2010 and 2019, including cardiovascular and obstetric factors, fetal events, delivery methods, and other complications over a mean 5-years post-delivery follow-up period.

Results

There were 1,040 women with CHD (5.35% of all deliveries). Compared to women without CHD, these women had longer hospital stays (7.83 ± 4.65 vs. 4.93 ± 3.26 days) and a higher death rate (1.92 vs. 0.02%). They also had a greater risk of comorbidities, including pre-term delivery (odds ratio: 13.65 vs. 6.71), heart failure (odds ratio: 4.90 vs. 0.40), and arrhythmia (odds ratio 12.69 vs. 4.69). Pulmonary hypertension, New York Heart Association functional class III~IV, and no congenital heart disease surgery prior to pregnancy were associated with adverse events such as cesarean section, pre-term delivery, and heart failure. The fetuses of mothers with CHD were more likely to be born pre-term (odds ratio: 13.65 vs. 6.71) and have low birth weight (odds ratio: 8.56 vs. 4.36). Eleven infants (1.82%) born to mothers with CHD and four infants (0.64%) born to mothers without CHD were diagnosed with CHD.

Conclusions

Women with CHD generally increase maternal and infant risk during pregnancy and the perinatal period. Pulmonary hypertension, decrease in cardiac function, and no previous CHD surgery increase the risk in women with CHD. Greater attention should be paid to pregnant women with CHD and their fetuses, newborns.

Management of Implantable Cardioverter-Defibrillators during Pregnancy-A Systematic Review

Background: With the advent of implantable cardioverter-defibrillator (ICD) technology in recent decades, patients with inherited or congenital cardiomyopathy have a greater chance of survival into adulthood. Women with ICDs in this group are now more likely to reach reproductive age. However, pregnancy represents a challenge for clinicians, as no guidelines for the treatment of pregnant women with an ICD are currently available. Methods: To analyze this issue, we performed a systematic screening of the literature using the keywords: pregnancy with ICD, lead fracture in pregnancy, lead thrombi in pregnancy, ventricular tachycardia in pregnancy, inappropriate shocks in pregnancy, ICD discharge in pregnancy and ICD shock in pregnancy. Of 1101 publications found, 27 publications were eligible for further analysis (four retrospective trials and 23 case reports). Results: According to physiological changes in pregnancy, resulting in an increase in heart rate and cardiac output, a vulnerability for malignant arrhythmias and device-related complications in ICD carriers might be suspected. While the literature is limited on this issue, maternal complications including arrhythmia burden with following ICD therapies, thromboembolic events and lead complications as well as inappropriate shock therapy have been reported. According to the limited available studies, associated risk seems not to be more frequent than in the general population and depends on the underlying cardiac pathology. Furthermore, worsening of heart failure and related cardiovascular disease have been reported with associated risk of preterm delivery. These observations are exaggerated by restricted applications of diagnostics and treatment due to the risk of fetal harm in this population. Conclusions: Due to limited data on management of ICDs during pregnancy, further scientific investigations are required. Consequently, careful risk assessment with individual risk evaluation and close follow ups with interdisciplinary treatment are recommended in pregnant ICD carriers.

Association of Adult Congenital Heart Disease With Pregnancy, Maternal, and Neonatal Outcomes

IMPORTANCE

With the help of medical advances, more women with adult congenital heart disease (ACHD) are becoming pregnant. Adverse maternal, obstetric, and neonatal events occur more frequently in women with ACHD than in the general obstetric population. Adult congenital heart disease is heterogeneous, yet few studies have assessed whether maternal and neonatal outcomes differ across ACHD subtypes.

OBJECTIVE

To assess the association of ACHD and its subtypes with pregnancy, maternal, and neonatal outcomes.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study used data from the Discharge Abstract Database, which contains information on all hospitalizations in Canada (except Quebec) from fiscal years 2001-2002 through 2014-2015. Discharge Abstract Database information was linked with maternal and infant hospital records across Canada. All women who gave birth in hospitals during the study period were included in the study. Data were analyzed from December 18, 2017, to March 22, 2019.

EXPOSURES

Women with ACHD were identified using diagnostic and procedural codes. Subtypes of ACHD were classified using the Anatomic and Clinical Classification of Congenital Heart Defects scheme.

MAIN OUTCOMES AND MEASURES

Primary outcomes were defined a priori and included severe maternal morbidity (measured using the Maternal Morbidity Outcomes Indicator), neonatal morbidity and mortality (measured using the Neonatal Adverse Outcomes Indicator), ischemic placental disease, preterm birth, congenital anomalies, and small-for-gestational-age births. Absolute and relative rates of each outcome were calculated overall and by ACHD subtype. Logistic regression using generalized estimating equations assessed crude and adjusted odds ratios (aORs) for each outcome in women with ACHD compared with women without ACHD after adjustment for comorbidities, mode of delivery, and study year.

RESULTS

The 2114 women with ACHD included in the analysis (mean [SD] age, 29.4 [5.7] years) had significantly higher odds of maternal morbidity (aOR, 2.7; 95% CI, 2.2-3.4) and neonatal morbidity and mortality (aOR, 1.8; 95% CI, 1.6-2.1) compared with women without ACHD (n = 2 682 451). Substantial variation was observed between women with different subtypes of ACHD. For example, the aORs of preterm birth (<37 weeks) varied from 0.4 (95% CI, 0.4-0.5) for women with anomalies of atrioventricular junctions and valves to 4.7 (95% CI, 2.9-7.5) for women with complex anomalies of atrioventricular connections.

CONCLUSIONS AND RELEVANCE

These results suggest that women with different subtypes of ACHD are not uniformly at risk for adverse maternal and neonatal outcomes. Although some women with ACHD can potentially expect healthy pregnancies, it appears that clinical care should be modified to address the heightened risks of certain ACHD subtypes.
