Pregnancy still contraindicated in pulmonary arterial hypertension related to congenital heart disease: True or false?

Pregnancy feasibility in women with mild pulmonary arterial hypertension: a systematic review and meta-analysis

BACKGROUND

The aim of this study was to evaluate the pregnancy feasibility of women with mild pulmonary hypertension according to pregnancy outcomes.

METHODS

This systematic review and meta-analysis compared the differences in maternal and fetal outcomes between mild and moderate-to-severe pulmonary hypertension. Relevant English and Chinese literature were searched in the PubMed, Embase, Cochrane Central Register of Controlled Trials (COCHRANE), CNKI, WanFang Data, and VIP databases between January 1st, 1990 and April 18th, 2023, and the references of the included articles and relevant systematic reviews were reviewed to determine whether studies were missed. The inclusion criteria were randomized controlled and observational studies (including case-control studies and cohort studies) examining maternal and fetal pregnancy outcomes with pulmonary hypertension. Conference abstracts, case reports, case series reports, non-comparative studies, and review articles were excluded.

RESULTS

This meta-analysis included 32 studies. In this study, maternal and fetal outcomes were better in the mild pulmonary hypertension group than in the moderate-to-severe group. Regarding maternal mortality, the mild group was much lower than the moderate to severe group. We found a significant decrease in maternal mortality in the mild group after 2010. However, no significant difference in maternal mortality before and after 2010 was observed in the moderate to severe group. Cardiac complications, ICU admission, neonatal preterm birth, small for gestational age infants, low birth weight infants, neonatal asphyxia, and neonatal mortality were significantly lower in the mild pulmonary hypertension group than in the moderate to severe pulmonary hypertension group. The cesarean section rates of the two groups were similar. However, the vaginal delivery rate in the mild pulmonary hypertension group was significantly higher than that in the moderate to severe pulmonary hypertension group.

CONCLUSIONS

This meta-analysis confirmed that pregnancies with mild pulmonary hypertension had significantly better maternal and fetal outcomes than those with moderate to severe pulmonary hypertension. For patients with mild pulmonary hypertension and good cardiac function, continued pregnancy or even delivery should be considered under multidisciplinary monitoring. However, maternal and fetal complications with moderate to severe pulmonary hypertension significantly increase. Hence, it is essential to evaluate pregnancy risk and terminate it in time.

Barriers and facilitators of experiencing pregnancy and motherhood with congenital heart disease: A secondary qualitative analysis

AIMS

To explore and describe perceived factors that favour or hinder the challenges faced by mothers with congenital heart disease during pregnancy and motherhood.

DESIGN

A secondary qualitative analysis, according to the interpretative phenomenological analysis approach.

METHODS

A previous study by Flocco et al., 2020 led us to identify that this population share risks, fear, worries and challenges related to pregnancy. To better understand two a priori themes, barriers and facilitators, we adopted The Standards for Reporting Qualitative Research guidelines, and the processes of credibility, transferability and dependability guaranteed the rigour.

RESULTS

The perceived barriers that were identified from the twelve semi-structured interviews were mainly identified in clinical and psychological risks, uncertainty about the future. The main facilitators were identified in positive mental attitude, self-motivation, trust in support by clinicians and nurses.

CONCLUSION

The study results confirmed two main a priori themes, revealing that CHD women perceive considerable obstacles and figure out facilitators to face the difficulties encountered in their path to become mothers.

Pregnancy in Congenital Heart Disease, Complicated by Pulmonary Arterial Hypertension—A Challenging Issue for the Pregnant Woman, the Foetus, and Healthcare Professionals

Background and Objectives: Pregnancy and delivery in patients with congenital heart disease (CHD) and pulmonary arterial hypertension (PAH) carry a very high risk for maternal and foetal complications and are contraindicated according to the guidelines. In the last decades, when an available modern PAH-targeted medication therapy and a new management concept improved patients’ well-being and survival, some PAH-CHD females decided to conceive. Of note, despite advanced treatment and modern healthcare system possibilities, dealing with pregnancy in a diverse PAH-CHD population is still challenging. The study aimed to share our experience with PAH-CHD pregnancies and discuss the risk assessment and current management of these patients with the combination of two rare diseases. Materials and Methods: The retrospective search of pulmonary hypertension and adult CHD registries in our hospital was performed, selecting all patients with CHD and PAH who conceived pregnancy from 2013 to 2021. Baseline demographic, clinical, and functional characteristics and clinical outcomes were collected. Results: Thirteen pregnancies in eight patients with PAH-CHD resulted in seven live births, three miscarriages, and three terminations. Five women were diagnosed with Eisenmenger syndrome (ES) and three with residual PAH after CHD repair. Before pregnancy, half of them were in WHO functional class III. Seven (87.5%) patients received targeted PAH treatment with sildenafil during pregnancy. In addition, the two most severe cases were administered with iloprost during peripartum. Three ES patients delivered preterm by Caesarean section under general anaesthesia. No neonatal mortality was reported. Maternal complications were observed in half of our cases. One patient died 12 days after the delivery in another hospital due to deterioration of heart failure. Conclusions: On the basis of our clinical experience, we conclude that pregnancy and delivery carry a high risk for maternal complications and should be avoided in women with PAH-CHD. The individualised approach of multidisciplinary care and appropriate monitoring are mandatory in reducing the risk of adverse outcomes.

Counseling for Perinatal Outcomes in Women with Congenital Heart Disease

As the adult congenital heart disease population grows, more women are reaching childbearing age. Women with moderate to complex congenital heart disease have an increased risk of morbidity and mortality than the general population. There is increased risk of prematurity and intrauterine growth restriction in infants. Regular preconceptual adult congenital heart disease care, contraception counseling, and multidisciplinary care during a pregnancy can help minimize the risk during pregnancy for both mother and baby.

Adult congenital heart disease with pulmonary arterial hypertension: mechanisms and management

Adult congenital heart disease (ACHD) encompasses a range of structural cardiac abnormalities present before birth attributable to abnormal foetal cardiac development. The pulmonary circulation of patients with ACHD and intracardiac or extracardiac defects is often exposed to increased blood flow and occasionally to systemic pressures. Depending on the location and magnitude of the defect as well as the time of surgical correction, the patient with ACHD is at risk of developing pulmonary arterial hypertension (PAH), which dramatically increases morbidity and mortality. It is encouraging that therapies applied in idiopathic PAH and significantly improve outcome are also effective in ACHD-related PAH (ACHD-PAH). This review summarizes the challenges encountered in the diagnosis and management of ACHD-PAH.

Exploring the lived experiences of pregnancy and early motherhood in Italian women with congenital heart disease: an interpretative phenomenological analysis

OBJECTIVE

This study explored the lived experiences of women with congenital heart disease (CHD) during pregnancy and early motherhood.

DESIGN

Qualitative study using semistructured interviews. Data were analysed according to interpretative phenomenological analysis.

SETTING

San Donato Milanese, Italy.

PARTICIPANTS

12 adult women during pregnancy or early motherhood.

RESULTS

Three main themes emerged from the analysis that were labelled as follows: 'Being a woman with CHD'; 'Being a mother with CHD'; and 'Don't be alone'. Mothers described both positive and negative feelings about their pregnancies and transitions from childless women to mothers with CHD. They needed supportive care to improve the management of their health during pregnancy and early motherhood.

CONCLUSION

This study explored the lived experiences of women with CHD during pregnancy and early motherhood. The emerged themes represent an initial framework for implementing theory-grounded educational and supportive strategies that improve self-care, engagement and quality of life for women with CHD. Furthermore, the study's results provide guidance for operationalising the described experiences into items and domains for future cross-national surveys.
