Background and study aims
Standardised monitoring of obstetric, maternal and fetal outcomes, as well as patient-reported outcomes and experiences (PROs and PREs), is needed to ensure that future recommendations take into account the needs and requirements of pregnant women with cardiovascular disease themselves. Currently, there is a lack of evidence on the impact of pregnancy in women with a cardiovascular profile on pregnancy outcomes. The development of a comprehensive patient registry combining clinical, maternal and fetal outcome measures, complemented by a validated set of PROs and PREs, is of paramount importance. There is also a need for scientific understanding of the relationship between these clinical outcomes and patient-reported outcome measures.
The aim of this study is to create a general registry for women with heart and/or vascular disease that will record clinical outcomes (such as disease-specific data and possible pregnancy complications), patient-reported outcomes, and experiences during and after pregnancy.

Who can participate?
Female patients with a current pregnancy who are being followed by a gynaecologist and/or cardiologist in the cardio-obstetrics department of one of the participating hospitals.

What does the study involve?
This study will collect data from medical records and questionnaires. Questionnaires will be sent digitally to participants, often a few days before their scheduled hospital appointment with their gynaecologist or cardiologist. These questionnaires will measure their experience of the care and support received during pregnancy and labour. These questionnaires will also measure how they feel (or felt) during this time.
In total, participants will be asked to complete questionnaires at three different times during their pregnancy: the first, second and third trimesters. They will also be asked to complete questionnaires at three different times after giving birth: in the first week, about 6 weeks, and about 12 weeks after giving birth.

What are the possible benefits and risks of participating?
Participation in the study is completely voluntary and participants have the right to refuse to take part in the study without this affecting their care in the hospital. They have the right to withdraw from the study at any time, even after they have signed the consent form. They do not have to give a reason for withdrawing your consent to participate. Withdrawal will not result in any disadvantages or loss of benefits.
There are no specific risks associated with taking part in this study. However, it is possible that certain questions about experiences and/or feelings may trigger certain emotions or memories. For this reason, the questionnaires will also be prepared and analysed with the utmost care for the mental and emotional wellbeing and privacy of the participants. The researchers may refer study participants to appropriate psychological care if they feel this is desirable for their general and mental wellbeing, but this will always be done in close consultation with the patient.
If participants agree to take part in this study, the researchers cannot confirm that they will personally benefit directly. The results will help the researchers to understand the experiences, feelings and other outcomes of women with cardiovascular disease during and after pregnancy. Taking part in the study will help our healthcare team improve the advice and support they give to these women in the future. In order to achieve this goal, participation in this survey will be very valuable.

Scientific titleDevelopment of a registry of clinical, patient-reported outcomes and experiences for pregnant women with cardiovascular conditions
Study acronymWelZCaVa
Study objectivesStandardised monitoring of obstetric, maternal and fetal outcomes, as well as patient-reported outcomes and experiences (PROMs and PREMs), is needed to ensure that future recommendations take into account the needs and requirements of pregnant women with cardiovascular disease themselves. Currently, there is a lack of evidence on the impact of pregnancy in women with a cardiovascular profile on pregnancy outcomes. The development of a comprehensive patient registry combining clinical, maternal and fetal outcome measures, complemented by a validated set of PROs and PREs, is of paramount importance. There is also a need for scientific understanding of the relationship between these clinical outcomes and patient-reported outcome measures.

This study, which is part of a PhD programme, aims to establish a multi-centre patient registry of pregnant women with acquired, hereditary or congenital cardiovascular disease, in which a range of obstetric, maternal and fetal outcomes, as well as PROMS and PREMS, will be collected during the perinatal and post-partum period (cf. 4th trimester). This study aims to:
1. Determine the impact of pregnancy through a range of maternal, obstetric and fetal/neonatal outcomes
2. Determine the impact of pregnancy through a range of patient-reported outcomes and experiences in the perinatal and post-partum period
3. Explore the associations between maternal, obstetric and fetal/neonatal outcomes and PROMS/PREMS in the perinatal and post-partum period

Health condition(s) or problem(s) studiedFemale patients who are currently pregnant and being followed for congenital, hereditary or acquired cardiovascular disease
InterventionData are collected using the medical/electronic patient record and a set of questionnaires covering the selected PROMS and PREMS.

The registry will collect data from the first consultation at a tertiary centre up to and including 12 weeks after delivery (cf. fourth trimester). There will be at least four data collection points for each enrolled pregnant woman: at least one data collection point during the perinatal period, depending on the date of enrolment and current gestational age (cf. trimester 1, 2 or 3) and at least three data collection points during the postpartum period (see week 1-2, 4-6 and 6-12 postpartum). At each data point, questionnaires will be sent out asking about patient-reported outcomes and/or experiences. Clinical data will be collected once during the perinatal period and once during the postpartum period to monitor more general maternal and fetal outcomes.
Intervention typeOther
Primary outcome measurePatient-reported outcomes:
1. The possible presence of depressive symptoms is measured using the validated Whooley scale
2. The possible presence of an anxiety disorder is measured using the General Anxiety Disorder 7 questionnaire
3. Autonomy and shared decision-making are assessed using the Mothers on Autonomous Decision Making (MADM) scale
4. Social support is measured using the validated Oslo-3 scale
5. Empowerment is assessed using the validated Pregnancy Related Empowerment Scale (PRES)
6. Symptoms of possible (postnatal) depression, anxiety and suicidal ideation assessed using the Edinburgh Postnatal Depression Scale (EPDS)
7. Mother-infant bonding is assessed using the Mother-Infant Bonding Scale (MIBS). The validated Postpartum Bonding Questionnaire (PBQ) is also administered at the same time to ensure that mother-child bonding has been properly assessed.

Patient-reported experiences:
Patient satisfaction will be measured using the validated Maternity Satisfaction with Care Questionnaire (MSCQ) developed as part of the Born in Belgium study.

The registry will collect these data from the first consultation in a tertiary centre up to and including 12 weeks after delivery (cf. fourth trimester). For each enrolled pregnant woman, there will be at least 4 data collection points: at least 1 data collection point during the perinatal period, depending on the date of enrolment and the current gestational age (cf. trimester 1, 2 or 3) and at least 3 data collection points during the postpartum period (cf. week 1, 6 and 12 postpartum).

Figure 1 of the study protocol provides a visual overview of the respective data collection points for demographics and clinical outcomes. Figure 2 also provides a visual overview of the respective data collection points for the PROMS and PREMS datasets. It is important to note that the date of enrolment during the perinatal period is a highly variable element of the study, where the date of the patient's first registration at the outpatient clinic may vary between trimester 1, 2 or 3. During this perinatal period there will be at least one measurement time per participating patient. However, depending on the patient's exact enrolment date and gestational age, an attempt will be made to provide one data collection point per trimester. Ideally, however, the maximum number of measurement times (one measurement time per trimester) should be achieved, as shown in the figure.
Secondary outcome measuresThe following set of obstetric, maternal and fetal/neonatal outcomes will be collected from the medical record once at 2 weeks postpartum:
1. The set of maternal and obstetric outcomes listed in Appendix 2 of the study protocol will consist of the following variables: maternal mortality, length of stay, haemorrhage; obstetric outcomes such as abruptio placentae, haemorrhage, emergency caesarean section, rupture of membranes (ROM); left ventricular ejection fraction, cardiomyopathy (CMP), arrhythmia, pulmonary hypertension, thromboembolic complications; hypertension, endocarditis and cardiomyopathy.
2. The set of fetal/neonatal outcomes listed in Appendix 3 of the protocol will consist of the following data: APGAR score, birth weight, length of stay, fetal mortality, reason for preterm birth, neonatal admission, neonatal mortality, intrauterine growth restriction (IUGR) and birth injury.

The registry will collect these data from the first consultation in a tertiary centre up to and including 12 weeks after delivery (cf. fourth trimester). For each enrolled pregnant woman, there will be at least 4 data collection points: at least 1 data collection point during the perinatal period, depending on the date of enrolment and the current gestational age (cf. trimester 1, 2 or 3) and at least 3 data collection points during the postpartum period (cf. week 1, 6 and 12 postpartum).

Figure 1 of the study protocol provides a visual overview of the respective data collection points for demographics and clinical outcomes. Figure 2 also provides a visual overview of the respective data collection points for the PROMS and PREMS datasets. It is important to note that the date of enrolment during the perinatal period is a highly variable element of the study, where the date of the patient's first registration at the outpatient clinic may vary between trimester 1, 2 or 3.
