Contains fulltext : 225482.pdf (Publisher’s version ) (Open Access), Congenital heart disease (CHD) affects 0.8% of live births and over the past decades technical improvements and large-scale repair has led to increased survival into adulthood of over 95% of the new-born. A new group of patients, those who survived their congenital heart defect, has emerged but late complications including heart failure, pulmonary hypertension (PH), arrhythmias, aneurysms and endocarditis appeared numerous, with a huge impact on mortality and morbidity. However, innovations over the past years have changed the landscape of adult CHD dramatically. In the diagnostic process important improvements have been made in the use of MRI, biomarkers, e‑health concepts and 3D visualisation of anatomy. Care is now concentrated in specialised centres, with a continuous emphasis on education and the introduction of weekly multidisciplinary consultations on diagnosis and intervention. Surgery and percutaneous intervention have been refined and new concepts applied, further reducing the burden of the congenital malformations. Research has matured from case series to global networks. Currently, adults with CHD are still facing high risks of early mortality and morbidity. By global collaboration and continuous education and development and innovation of our diagnostic and therapeutic arsenal, we will improve the perspectives of these young patients.

Objective:N-terminal pro-brain natriuretic peptide has an established role in the diagnosis and prognosis of heart failure. In Fontan patients, this peptide is often increased, but its diagnostic value in this particular non-physiologic, univentricular circulation is unclear. We investigated whether N-terminal pro-brain natriuretic peptide represents ventricular function or other key variables in Fontan patients.Methods and results:Ninety-five consecutive Fontan patients ≥10 years old who attended the outpatient clinic of the Center for Congenital Heart Diseases in 2012-2013 were included. Time since Fontan completion was 16 ± 9 years. Median N-terminal pro-brain natriuretic peptide was 114 (61-264) ng/l and was higher than gender-and age-dependent normal values in 54% of the patients. Peptide Z-scores were higher in patients in NYHA class III/IV compared to those in class I/II, but did not correlate with ventricular function assessed by MRI and echocardiography, nor with peak exercise capacity. Instead, peptide Z-scores significantly correlated with follow-up duration after Fontan completion (p < 0.001), right ventricular morphology (p = 0.004), indexed ventricular mass (p = 0.001), and inferior caval vein diameter (p < 0.001) (adjusted R2 = 0.615).Conclusions:N-terminal pro-brain natriuretic peptide levels in Fontan patients correlate with functional class, but do not necessarily indicate ventricular dysfunction. Increased peptide levels were associated with a longer existence of the Fontan

Hypertensive disorders in pregnant women are associated with inadequate uteroplacental flow, which is related to adverse offspring outcome. The aim of this study was to investigate the relationship of maternal cardiac function, placental function and pregnancy complications in women with rCoA. METHODS: We included 49 pregnant women with rCoA and 69 controls from the prospective ZAHARA-studies (Zwangerschap bij Aangeboren HARtAfwijkingen, pregnancy in congenital heart disease). Clinical evaluation, echocardiography and uteroplacental Doppler flow (UDF) measurements were performed at 20 and 32weeks gestation. Univariable regression analysis was performed. RESULTS: Comparison of rCoA and healthy women. In women with rCoA, tricuspid annular plane systolic excursion (TAPSE) decreased during pregnancy (25.7mm to 22.8mm, P=0.006). UDF indices and pregnancy complication rates were similar in both groups. Offspring of rCoA women had lower birth weight (3233g versus 3578g, P=0.001), which was associated with beta-blocker use during pregnancy (beta=-418.0, P=0.01). Association of cardiac function and UDF. Right ventricular (RV) function before pregnancy (TAPSE) and at 20weeks gestation (TAPSE and RV fractional area change) were associated with impaired UDF indices (umbilical artery pulsatility index at 20weeks beta=-0.02, P=0.01, resistance index at 20 and 32weeks beta=-0.01, P=0.02 and beta=-0.02, P=0.01 and uterine artery pulsatility and resistance index at 20weeks gestation beta=-0.02, P=0.05 and beta=-0.01, P=0.02). CONCLUSIONS: Women with rCoA tolerate pregnancy well. However, RV function is altered and is associated with impaired placentation.

Our objective is to focus on patients treated surgically in childhood (0-18 y). We study the intended treatment (biventricular or 1.5 ventricle repair or univentricular palliation), freedom from unplanned reoperation and survival of this specific age group, in a nationwide study. DESIGN: Records of all Ebstein's anomaly patients born between 1980 and 2013 were reviewed. Demographic variables, intraoperative procedures and postoperative outcomes were analyzed. RESULTS: Sixty-three patients underwent 109 operations. Median follow-up after diagnosis was 121 months (range 0-216 months). Twenty-nine (46%) patients required surgery in the first year of life, including 21 who required neonatal surgery. The intended treatment was biventricular (n = 37, 59%) and 1.5 ventricle (n = 5, 8%) repair or univentricular (n = 21, 33%) palliation. The one-, five-, and 10-year freedom from unplanned reoperation was 89%, 79%, and 75% respectively. There were nine (14%) in hospital deaths (within 30 d after surgery). Causes of death were low cardiac output syndrome, cardiac failure, hypoxemia, pulmonary hypertension or an unknown cause. There were no late deaths. CONCLUSIONS: Surgery in childhood represents the worse spectrum of disease, biventricular repair is often not applied. Patients often face revision surgery. Mortality is limited to the immediate postsurgical period.

Contains fulltext : 171019.pdf (publisher's version ) (Open Access), OBJECTIVES: N-terminal Btype natriuretic peptide (NT-proBNP) is an important biomarker for the detection of heart failure. Adults with congenital heart disease (ACHD) and a prosthetic heart valve are at risk for heart failure. This study aimed to determine the value of NT-proBNP in ACHD patients with a prosthetic valve and investigate its relationship with cardiac function and exercise capacity. METHODS: In this multi-centre cross-sectional observational study, data regarding medical history, echocardiography, exercise testing (VO2peak) and laboratory blood evaluation (including NT-proBNP) were collected in ACHD patients with a single prosthetic valve (either homografts, heterografts or mechanical valves). RESULTS: A total of 306 ACHD patients with pulmonary valve replacement (PVR, n = 139), aortic valve replacement (n = 141), mitral valve replacement (n = 21) or tricuspid valve replacement (n = 5) were investigated. The majority of patients (77 %) were in NYHA class I or II. Elevated NT-proBNP levels (cut-off >/=125 pg/ml) were found in 50 % of the patients, with the highest levels in patients with mitral valve replacements. In this study population, NT-proBNP levels were associated with gender (p = 0.029) and VO2max (p < 0.001). In PVR patients, NT-proBNP levels were associated with lower VO2peak, also after adjustment for age, gender and age at valve replacement in a multivariate model (p = 0.015). CONCLUSIONS: In patients with ACHD and a prosthetic valve, elevated NT-proBNP levels are frequently observed despite preserved NYHA class. In PVR patients, a higher NT-proBNP level was associated with a lower VO2peak. These results may be of importance in the ongoing discussion about the timing of valve replacement in patients with CHD.

Objectives: To investigate outcome of pregnancy and fertility in women with double outlet right ventricle (DORV). Methods: Using 2 congenital heart disease registries, 21 female patients with DORV (aged 18-39 years) were retrospectively identified. Detailed recordings of each patient and their completed (>20 weeks gestation) pregnancies were recorded. Results: Overall, 10 patients had 19 pregnancies, including 3 spontaneous miscarriages (16%). During the 16 live birth pregnancies, primarily (serious) noncardiac complications were observed, e.g. premature labor/delivery (n = 7 and n = 3, respectively), small for gestational age (n = 4), preeclampsia (n = 2) and recurrence of congenital heart disease (n = 2). Except for postpartum endocarditis and deterioration of subpulmonary obstruction, only mild cardiac complication pregnancies were recorded. Two women with children reported secondary female infertility. Several menstrual cycle disorders were reported: secondary amenorrhea (n = 4), primary amenorrhea (n = 3) and oligomenorrhea (n = 2). Conclusion: Successful pregnancy in women with DORV is possible. Primarily noncardiac complications were observed and only few (minor) cardiac complications. Infertility and menstrual cycle disorders appear to be more prevalent. Copyright

This review describes the outcome of 2,491 pregnancies, including 377 miscarriages (15%) and 114 elective abortions (5%). Important cardiac complications were seen in 11% of the pregnancies. Obstetric complications do not appear to be more prevalent. In complex CHD, premature delivery rates are high, and more children are small for gestational age. The offspring mortality was high throughout the spectrum and was related to the relatively high rate of premature delivery and recurrence of CHD.

Contains fulltext : 49575.pdf (publisher's version ) (Closed access), BACKGROUND: Information on the outcome of pregnancy in patients with pulmonary valvar stenosis is scarce, mostly limited to cardiac complications observed during pregnancy. OBJECTIVES: To investigate the magnitude and determinants of non-cardiac and fetal risks during pregnancy of women with isolated pulmonary valvar stenosis. METHODS: Using the nationwide registry (CONgenital CORvitia), 106 women with (un-)corrected pulmonary valvar stenosis receiving care in six tertiary medical centres in The Netherlands were included. A total of 51 women had 108 pregnancies, including 21 (19%) miscarriages and 6 elective abortions. RESULTS: In the 81 completed (>20 weeks of gestation) pregnancies, we observed a high number of hypertension-related disorders (n = 12, 15%, including pre-eclampsia (n = 4) and eclampsia (n = 2)), premature deliveries (n = 14, 17%, including one twin) and thromboembolic events (n = 3, 3.7%). Furthermore, recurrence of congenital heart defects in the offspring was detected in three children (3.7%, pulmonary valvar stenosis (n = 2) and complete transposition of the great arteries in combination with anencephaly). In addition to the intrauterine fetal demise of the transposition child, three other children died shortly after birth owing to immaturity, hydrocephalus combined with prematurity and meningitis (overall offspring mortality, 4.8%). CONCLUSION: In this largest report on pregnancy in women with (un-) corrected isolated pulmonary valvar stenosis, an excessive number of (serious) non-cardiac complications and mortality were observed in the offspring.

DESIGN AND PATIENTS: Two congenital heart disease registries were used to investigate 38 female patients who had undergone Fontan palliation (aged 18-45 years): atriopulmonary anastomosis (n = 23), atrioventricular connection (n = 5) and total cavopulmonary connection (n = 10). RESULTS: Six women had 10 pregnancies, including five miscarriages (50%) and one aborted ectopic pregnancy. During the remaining four live-birth pregnancies clinically significant complications were encountered: New York Heart Association class deterioration; atrial fibrillation; gestational hypertension; premature rupture of membranes; premature delivery; fetal growth retardation and neonatal death. Four of seven women who had attempted to become pregnant reported female infertility: non-specified secondary infertility (n = 2), uterus bicornis (n = 1) and related to endometriosis (n = 1). Moreover, several important menstrual cycle disorders were documented. In particular, the incidence of primary amenorrhoea was high (n = 15, 40%), which resulted in a significant increase in age at menarche (14.6 (SD 2.1) years, p < 0.0001, compared with the general population). CONCLUSION: Women can successfully complete pregnancy after adequate Fontan palliation without important long-term sequelae, although it is often complicated by clinically significant (non-)cardiac events. In addition, subfertility or infertility and menstrual disorders were common.

Using a nationwide congenital heart disease registry (CONgenital CORvitia [CONCOR]), 9 women with biventricular repair for PAVSD (aged 21 to 38 years) were identified. Ten pregnancies were observed in 5 different women with PAVSD, including 3 spontaneous miscarriages. Clinically significant (non)cardiac complications were documented in 3 of 7 completed pregnancies. These complications were: (1) atrioventricular reentry tachycardia with symptomatic right-sided heart failure; (2) eclampsia with hemolysis, elevated liver enzymes, and low platelets syndrome further complicated by abruptio placentae leading to premature delivery of a small-for-gestational-age child; and (3) premature delivery due to cervical insufficiency with antepartum demise of an immature child. Furthermore, none of the women reported infertility. Moreover, none of the women reported irregularities of their natural menstrual cycle (age at menarche 13 years; cycle duration 28 days), with the exception of delayed menarche (>16 years) in 2 patients. In conclusion, successful pregnancy in patients with biventricular repair of PAVSD is possible, although often complicated by serious clinically significant events. Infertility and menstrual cycle disorders do not appear to be more prevalent, except for a high incidence of primary amenorrhea.

Using a nationwide registry (CONCOR), 37 patients with pulmonary atresia were identified, 6 of whom (aged 21 to 34 years) had biventricular repair for PAIVS. Three PAIVS patients had a total of 5 pregnancies, including 1 abortion and 1 ectopic pregnancy. Besides minor noncardiac complications, the 3 live-birth pregnancies were successful. None of the women reported infertility or irregularities (hypermenorrhea, dysmenorrhea, polymenorrhoea, oligomenorrhea, or amenorrhea) of their natural menstrual cycle. In conclusion, successful pregnancy in women with biventricular repair for PAIVS is possible, and only minor complications were observed. Infertility and menstrual cycle disorders do not appear to be more prevalent than usual.

DESIGN AND PATIENTS: Two congenital heart disease registries were used to investigate 38 female patients who had undergone Fontan palliation (aged 18-45 years): atriopulmonary anastomosis (n = 23), atrioventricular connection (n = 5) and total cavopulmonary connection (n = 10). RESULTS: Six women had 10 pregnancies, including five miscarriages (50%) and one aborted ectopic pregnancy. During the remaining four live-birth pregnancies clinically significant complications were encountered: New York Heart Association class deterioration; atrial fibrillation; gestational hypertension; premature rupture of membranes; premature delivery; fetal growth retardation and neonatal death. Four of seven women who had attempted to become pregnant reported female infertility: non-specified secondary infertility (n = 2), uterus bicornis (n = 1) and related to endometriosis (n = 1). Moreover, several important menstrual cycle disorders were documented. In particular, the incidence of primary amenorrhoea was high (n = 15, 40%), which resulted in a significant increase in age at menarche (14.6 (SD 2.1) years, p < 0.0001, compared with the general population). CONCLUSION: Women can successfully complete pregnancy after adequate Fontan palliation without important long-term sequelae, although it is often complicated by clinically significant (non-)cardiac events. In addition, subfertility or infertility and menstrual disorders were common.

OBJECTIVES: To investigate the magnitude and determinants of non-cardiac and fetal risks during pregnancy of women with isolated pulmonary valvar stenosis. METHODS: Using the nationwide registry (CONgenital CORvitia), 106 women with (un-)corrected pulmonary valvar stenosis receiving care in six tertiary medical centres in The Netherlands were included. A total of 51 women had 108 pregnancies, including 21 (19%) miscarriages and 6 elective abortions. RESULTS: In the 81 completed (>20 weeks of gestation) pregnancies, we observed a high number of hypertension-related disorders (n = 12, 15%, including pre-eclampsia (n = 4) and eclampsia (n = 2)), premature deliveries (n = 14, 17%, including one twin) and thromboembolic events (n = 3, 3.7%). Furthermore, recurrence of congenital heart defects in the offspring was detected in three children (3.7%, pulmonary valvar stenosis (n = 2) and complete transposition of the great arteries in combination with anencephaly). In addition to the intrauterine fetal demise of the transposition child, three other children died shortly after birth owing to immaturity, hydrocephalus combined with prematurity and meningitis (overall offspring mortality, 4.8%). CONCLUSION: In this largest report on pregnancy in women with (un-) corrected isolated pulmonary valvar stenosis, an excessive number of (serious) non-cardiac complications and mortality were observed in the offspring.

DESIGN: Data were collected from 83 patients through interviews and review of medical records. RESULTS: In 29 patients 63 pregnancies were observed, of which 13 ended in an abortion. Fifty successful pregnancies were observed in 26 patients. During six successful pregnancies (12%) complications (symptomatic right sided heart failure, arrhythmias, or both) occurred. Both patients who developed symptomatic heart failure had severe pulmonary regurgitation. No clear relation between offspring mortality, premature birth or being small for gestational age, and cardiac characteristics of the mother was identified. Fifty seven patients were childless (41 (72%) voluntarily). Recurrence risk for congenital heart disease was 2.2%. Infertility was uncommon. CONCLUSIONS: Although complications did occur in five of 26 (19%) of the patients with a corrected tetralogy of Fallot, pregnancy was generally well tolerated in this largest report so far. No obvious predictors for maternal events or child outcome were determined, except for a possible relation between severe pulmonary regurgitation and symptomatic heart failure.
