This study sought to determine the independent role of N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels in addition to other parameters in predicting adverse cardiovascular events during pregnancy in women with CHD. METHODS AND RESULTS: We conducted a national, prospective multicentre cohort study. Follow-up with clinical evaluation and echocardiography and NT-proBNP measurement was performed at 20-week gestation. Adverse cardiovascular events occurred in 10.3% of 213 pregnancies. N-terminal pro-B-type natriuretic peptide levels >128 pg/mL at 20-week gestation, the presence of a mechanical valve, and subpulmonary ventricular dysfunction before conception were independently associated with events [odds ratio (OR) 10.6 (P = 0.039), OR 12.0 (P = 0.016), and OR 4.2 (P = 0.041), respectively]. The negative predictive value of NT-proBNP levels 128 pg/mL at 20 weeks of gestation had an additional value in predicting the occurrence of adverse cardiovascular events on the top of the other identified predictors (area under the curve 0.90 vs. 0.78, P = 0.035). CONCLUSION: Increased NT-proBNP levels at 20 weeks of gestation are an independent risk predictor of cardiovascular events during pregnancy in women with CHD.

DESIGN: A retrospective multicentre study. SETTING: Tertiary centres in the Netherlands and Belgium. METHODS: Women were identified using two congenital heart disease registries. Eighty-eight women were identified who had experienced 202 pregnancies, including 46 miscarriages and nine terminations of pregnancy. Information on each completed pregnancy (n = 147; unrepaired VSD, n = 104; repaired VSD, n = 43) was obtained using medical records and telephone interviews. Data from the Generation R database (prospective cohort study; n = 9667) were used to determine the background risk (controls). Odds ratios and 95% CI were estimated using general estimation equation analysis adjusted for multiple pregnancies per woman, maternal age and parity status. MAIN OUTCOME MEASURES: Adjusted odds ratios (AORs) for developing pregnancy complications in relation to corrective status. RESULTS: Pregnancies in women with an unrepaired VSD were associated with a higher risk of pre-eclampsia (AOR 4.59, 95% CI 2.01-10.5, P < 0.001) compared with controls. No differences were observed when comparing women with repaired VSD and controls. Pregnancies in women with repaired VSD were associated with a higher risk of premature labour (AOR 4.02, 95% CI 1.12-14.4, P = 0.03) and small-for-gestational-age (SGA) births (AOR 4.09, 95% CI 1.27-13.2, P = 0.02) compared with women with unrepaired VSD. CONCLUSIONS: Women with unrepaired VSD are at increased risk of pre-eclampsia, which suggests that it is not a benign condition. In addition, women with repaired VSD are at increased risk of premature labour and SGA births compared with women with unrepaired VSD. 01 mei 2010

DESIGN: A retrospective multicentre study. SETTING: Tertiary centres in the Netherlands and Belgium. POPULATION: Women with ASD without associated complex cardiac lesions. METHODS: Women were identified using two congenital heart disease registries. One hundred women were identified who had 243 pregnancies, including 49 miscarriages and six terminations of pregnancy. Detailed information on each completed pregnancy (n = 188; unrepaired ASD, n = 133; repaired ASD, n = 55) was obtained using medical records and telephone interviews. In addition, data from the Generation R database (a prospective cohort study; n = 9667) were used to determine the background risk (control group). MAIN OUTCOME MEASURES: Adjusted odds ratios (AORs) for cardiac, obstetric and neonatal events controlled for multiple pregnancies per woman using general estimating equation analysis. RESULTS: Women with an unrepaired ASD had a higher risk of neonatal events (AOR = 2.99, 95% confidence interval [CI] 1.14-7.89, P = 0.027) than women with a repaired ASD. The risk of cardiac and obstetric complications was comparable between women with unrepaired and repaired ASDs. Compared with the general population, women with an unrepaired ASD had higher risks of pre-eclampsia (AOR = 3.54, 95% CI 1.26-9.98, P = 0.017), small-for-gestational-age births (AOR = 1.95, 95% CI 1.15-3.30, P = 0.013) and fetal mortality (AOR = 5.55, 95% CI 1.77-17.4, P = 0.003). By contrast, no differences were observed when comparing women with a repaired ASD versus controls. CONCLUSIONS: Women with an unrepaired ASD are at increased risk of neonatal events in comparison with women with a repaired ASD. Compared with the general population, women with an unrepaired ASD are at increased risk of pre-eclampsia, small-for-gestational-age births and fetal mortality.

In this paper the Working Group on Myocardial and Pericardial Disease proposes a revised definition of dilated cardiomyopathy (DCM) in an attempt to bridge the gap between our recent understanding of the disease spectrum and its clinical presentation in relatives, which is key for early diagnosis and the institution of potential preventative measures. We also provide practical hints to identify subsets of the DCM syndrome where aetiology directed management has great clinical relevance. © The Author 2016.

Item does not contain fulltext OBJECTIVE: To investigate the existing evidence for a link between maternal cardiac function, abnormal uteroplacental flow and poor perinatal outcome in women with and without known cardiac disease. METHODS: PubMed and EMBASE databases were searched systematically for studies relating cardiac functional parameters and uteroplacental Doppler flow with pregnancy outcome in women with pre-existing congenital cardiac disease and women without known cardiac disease. Only studies based on echocardiography were included. RESULTS: From 1732 citations, 10 articles were included. In women with known congenital heart disease, a relationship was found between abnormal uteroplacental Doppler flow patterns and cardiac function before and during pregnancy. Conversely, women without a history of congenital heart disease, but with abnormal uterine artery resistance and pregnancy complications, more often showed global left ventricular diastolic dysfunction (33%; P = 0.0001), impaired myocardial relaxation (72%; P < 0.0001) and left ventricular systolic dysfunction (17%; P = 0.006), even up to 1 year postpartum. CONCLUSION: There is increasing evidence for an association between pre-existing subclinical cardiac dysfunction, poor placentation (reflected by uteroplacental Doppler flow abnormalities) and poor pregnancy outcome. It may be postulated that pre-existing suboptimal cardiac performance, as a result of either congenital heart disease or a subclinical latent condition, is one of the common denominators of poor placentation, leading to poor pregnancy outcome.

Item does not contain fulltext OBJECTIVES: Adequate prepregnancy prediction of maternal cardiovascular and offspring risk is important for counselling and management of pregnancy in women with congenital heart disease (CHD). Therefore we performed a study to identify the optimal assessment strategy for estimating the risk of pregnancy in women with CHD. METHODS: In this prospective study, we determined the outcomes of 213 pregnancies in 203 women with CHD. The ZAHARA I (Zwangerschap bij Aangeboren HARtAfwijkingen I) and CARPREG (CARdiac disease in PREGnancy) risk scores were calculated for each pregnancy, as was the total number of cardiovascular (TPc) or offspring risk predictors (TPo) from these and other studies combined. Pregnancies were also classified according to the modified WHO classification of maternal cardiovascular risk and according to disease complexity (DC). RESULTS: Maternal cardiovascular events occurred during 22 pregnancies (10.3%). Offspring events occurred during 77 pregnancies in 81 children (37.3%). Cardiovascular and offspring event rates increased with higher risk scores, higher TPc or TPo, higher WHO class and greater DC. The highest area under the curve (AUC) for maternal cardiovascular risk was achieved by the WHO class (AUC: 0.77, p
