Vliegen (b), Albert de Roos (a) Abstract: Cardiovascular magnetic resonance (CMR) is becoming an important tool in the clinical management of patients with congenital heart disease. Because of the diverse problems patients may face after initial correction for tetralogy of Fallot and the large amount of CMR techniques that can be applied, creating a patient-orientated imaging protocol is a difficult issue. Although it is still not certain what the impact of some parameters, provided by CMR, should be on clinical decision making, new techniques are being developed and applied. In this report, we review the current clinical issues in patients with tetralogy of Fallot and review the current implication and limitations of CMR in this patient category.

Background: Risk stratification in patients with repaired tetralogy of Fallot (rTOF) have focused on poor clinical outcomes while predictors of a benign clinical course have not been characterized.Objective: The goal of this study was to Identify cardiac magnetic resonance (CMR) markers of a good clinical course late after TOF repair.Methods: Clinical and CMR data from the International Multicenter TOF Registry (INDICATOR) were analyzed. The primary outcome was time to the earliest occurrence of a composite of death, aborted sudden death, and sustained ventricular tachycardia (VT). The secondary outcome was time to the earliest occurrence of atrial arrhythmia, nonsustained VT, and NYHA class >II. Multinomial regression was used to identify predictors of the 3-category outcome: (a) good outcome, defined as freedom from the primary AND secondary outcomes at age 50 years; (b) poor outcome, defined as presence of the primary outcome before age 50 years; and (c) intermediate outcome, defined as not fulfilling criteria for good or poor outcomes.Results: Among 1088 eligible patients, 96 had good outcome, 60 experienced poor outcome, and 932 had intermediate outcome. Patients were age 25.8±10.8 years at the time of the index CMR. Median follow-up was 5.8 years (IQR 3.0, 9.9) after CMR in event-free patients. By univariate analysis, smaller right ventricular (RV) end-systolic and end-diastolic volume index, smaller left ventricular end-systolic volume index, higher right and left ventricular ejection fraction, lower right and left ventricular mass index, and lower left ventricular mass/volume ratio were associated with good outcome. Multivariable modeling identified higher RV ejection fraction (OR 2.38 per 10% increase, P = .002) and lower RV mass index (OR 1.72, per 10 g/m2 decrease, P = .002) as independently associated with good outcome after adjusting for age at CMR. Classification and regression tree analysis identified important thresholds associated with good outcome that were specific to patients age ≥37 years at the time of CMR; these were RV ejection fraction ≥42% and RV mass index <39 g/m2.Conclusions: Adults with rTOF and no more than mild RV dysfunction combined with no significant RV hypertrophy are likely to be free from serious adverse clinical events into their sixth decade of life and may require less frequent cardiac testing.

Background: Sudden cardiac death (SCD) is the main preventable cause of death in patients with adult congenital heart disease (ACHD). Since robust risk stratification methods are lacking, we developed a risk score model to predict SCD in patients with ACHD: the PRospEctiVE study on implaNTable cardIOverter defibrillator therapy and suddeN cardiac death in Adults with Congenital Heart Disease (PREVENTION-ACHD) risk score model.Objective: The purpose of this study was to prospectively study predicted SCD risk using the PREVENTION-ACHD risk score model and actual SCD and sustained ventricular tachycardia/ventricular fibrillation (VT/VF) rates in patients with ACHD.Methods: The PREVENTION-ACHD risk score model assigns 1 point each to coronary artery disease, New York Heart Association class II/III heart failure, supraventricular tachycardia, systemic ejection fraction < 40%, subpulmonary ejection fraction < 40%, QRS duration ≥ 120 ms, and QT dispersion ≥ 70 ms. SCD risk was calculated for each patient. An annual predicted risk of ≥3% constituted high risk. The primary outcome was SCD or VT/VF after 2 years. The secondary outcome was SCD.Results: The study included 783 consecutive patients with ACHD (n=239 (31%) left-sided lesions; n=138 (18%) tetralogy of Fallot; n=108 (14%) closed atrial septal defect; median age 36 years; interquartile range 28-47 years; n=401 (51%) men). The PREVENTION-ACHD risk score model identified 58 high-risk patients. Eight patients (4 at high risk) experienced the primary outcome. The Kaplan-Meier estimates were 7% (95% confidence interval [CI] 0.1%-13.3%) in the high-risk group and 0.6% (95% CI 0.0%-1.1%) in the low-risk group (hazard ratio 12.5; 95% CI 3.1-50.9; P < .001). The risk score model's sensitivity was 0.5 and specificity 0.93, resulting in a C-statistic of 0.75 (95% CI 0.57-0.90). The hazard ratio for SCD was 12.4 (95% CI 1.8-88.1) (P = .01); the sensitivity and specificity were 0.5 and 0.92, and the C-statistic was 0.81 (95% CI 0.67-0.95).Conclusion: The PREVENTION-ACHD risk score model provides greater accuracy in SCD or VT/VF risk stratification as compared with current guideline indications and identifies patients with ACHD who may benefit from preventive implantable cardioverter-defibrillator implantation.

Renin-angiotensin-aldosterone system (RAAS) inhibition with angiotensin II receptor blockers or angiotensin-converting enzyme inhibitors is beneficial in patients with acquired left ventricular dysfunction. Adult patients with tetralogy of Fallot (TOF) with right ventricular (RV) dysfunction are at high risk for heart failure, arrhythmias, and sudden cardiac death. However, the efficacy of RAAS inhibition has not been established in these patients.Methods: The REDEFINE is an investigator-initiated, multicenter, prospective, randomized, double-blind, placebo-controlled trial to study the effects of the angiotensin II receptor blocker losartan (target dosage of 150 mg once daily) in adult patients with TOF. Patients with RV dysfunction in the absence of severe valvular dysfunction are eligible for inclusion. The primary end point is the change in RV ejection fraction after 18 to 24 months, as measured by cardiovascular magnetic resonance imaging. In addition, laboratory measurements, echocardiography, and cardiopulmonary exercise testing are performed.Conclusion: The REDEFINE trial will study the effects of RAAS inhibition with losartan in TOF patients with RV dysfunction.

The number of adults with congenital heart disease (CHD) has increased markedly over the past few decades as a result of astounding successes in pediatric cardiac care. Nevertheless, it is now well understood that CHD is not cured but palliated, such that life-long expert care is required to optimize outcomes. All countries in the world that experience improved survival in CHD must face new challenges inherent to the emergence of a growing and aging CHD population with changing needs and medical and psychosocial issues. Founded in 1992, the International Society for Adult Congenital Heart Disease (ISACHD) is the leading global organization of professionals dedicated to pursuing excellence in the care of adults with CHD worldwide. Recognizing the unique and varied issues involved in caring for adults with CHD, ISACHD established a task force to assess the current status of care for adults with CHD across the globe, highlight major challenges and priorities, and provide future direction. The writing committee consisted of experts from North America, South America, Europe, South Asia, East Asia, and Oceania. The committee was divided into subgroups to review key aspects of adult CHD (ACHD) care. Regional representatives were tasked with investigating and reporting on relevant local issues as accurately as possible, within the constraints of available data. The resulting ISACHD position statement addresses changing patterns of worldwide epidemiology, models of care and organization of care, education and training, and the global research landscape in ACHD.

Rationale: A number of randomized trials are underway, which will address the effects of angiotensin receptor blockers (ARBs) on aortic root enlargement and a range of other end points in patients with Marfan syndrome. If individual participant data from these trials were to be combined, a meta-analysis of the resulting data, totaling approximately 2,300 patients, would allow estimation across a number of trials of the treatment effects both of ARB therapy and of β-blockade. Such an analysis would also allow estimation of treatment effects in particular subgroups of patients on a range of end points of interest and would allow a more powerful estimate of the effects of these treatments on a composite end point of several clinical outcomes than would be available from any individual trial.Design: A prospective, collaborative meta-analysis based on individual patient data from all randomized trials in Marfan syndrome of (i) ARBs versus placebo (or open-label control) and (ii) ARBs versus β-blockers will be performed. A prospective study design, in which the principal hypotheses, trial eligibility criteria, analyses, and methods are specified in advance of the unblinding of the component trials, will help to limit bias owing to data-dependent emphasis on the results of particular trials. The use of individual patient data will allow for analysis of the effects of ARBs in particular patient subgroups and for time-to-event analysis for clinical outcomes. The meta-analysis protocol summarized in this report was written on behalf of the Marfan Treatment Trialists' Collaboration and finalized in late 2012, without foreknowledge of the results of any component trial, and will be made available online (http://www.ctsu.ox.ac.uk/research/meta-trials).

Background Pregnancy is increasingly common in women with congenital heart disease (CHD), but little is known about long-term cardiovascular outcome after pregnancy in these patients. We studied the incidence of cardiovascular events 1-year postpartum and compared cardiac function prepregnancy and 1-year postpartum in women with CHD. Methods From our national, prospective multicenter cohort study, 172 women were studied. Follow-up with clinical evaluation and echocardiography and NT-proBNP measurement were performed during pregnancy and 12 months postpartum. Cardiovascular events were defined as need for an urgent invasive cardiovascular procedure, heart failure, arrhythmia, thromboembolic events, myocardial infarction, cardiac arrest, cardiac death, endocarditis, and aortic dissection. Results Cardiovascular events were observed after 11 pregnancies (6.4%). Women with cardiovascular events postpartum had significant higher NT-proBNP values at 20-week gestation (191 [137-288] vs 102.5 [57-167]; P = .049) and 1-year postpartum compared with women without cardiovascular events postpartum (306 [129-592] vs 105 [54-187] pg/mL; P = .014). Women with cardiovascular events during pregnancy were at higher risk for late cardiovascular events (HR 7.1; 95% CI 2.0-25.3; P = .003). In women with cardiovascular events during pregnancy, subpulmonary end-diastolic diameter had significantly increased 1-year postpartum (39.0 [36.0-48.0] to 44.0 [40.0-50.0]; P = .028). No other significant differences were found in cardiac function or size 1-year postpartum compared with preconception values. Conclusions Cardiovascular events are relatively rare 1 year after pregnancy in women with CHD. Women with cardiovascular events during pregnancy are prone to develop cardiovascular events 1-year postpartum and have increased subpulmonary ventricular diameter compared with preconception values.

Objectives: Right ventricular (RV) failure after cardiac surgery is a clinical entity with high morbidity and mortality. Patients with congenital heart disease (CHD) often undergo right-sided cardiac surgery. The authors aimed to identify determinants of RV failure after cardiac surgery to differentiate patients with increased risk. Design: A retrospective chart review. Setting: University hospital. Participants: Adults with CHD operated on between January 2001 and January 2011. Interventions: Clinical characteristics, laboratory tests, surgical data, and intensive care unit outcome were obtained from medical records. Measurements and Main Results: The diagnosis of clinical RV failure was made by careful review of the medical records by 2 independent physicians. Patients only were identified as having RV failure if (1) they had elevated jugular venous pressure, (2) they had impaired postoperative RV function on transthoracic echocardiography, and (3) a diagnosis of RV failure was documented clearly in the medical charts by the treating physician. Data of 412 consecutive patients (median age 36 [range 18-74] years, 56% male) were studied. Eighteen patients had clinical RV failure (4.4%) postoperatively, of whom 6 patients died. Patients undergoing left- and both-sided surgery had an equal risk of developing clinical RV failure as compared with patients undergoing right-sided surgery. In multivariate logistic regression analysis, preoperative impaired RV function, supraventricular tachycardia, and cardiopulmonary bypass time >150 minutes were the strongest determinants of clinical RV failure (p<0.05, for all). Conclusions: RV failure after cardiac surgery is a serious complication, and occurs regardless of the side of surgery. A tailored approach in patients with CHD at highest risk of RV failure should be considered. [Copyright &y& Elsevier]

Purpose: The prevalence of adult patients with congenital heart disease (CHD) has been reported with a high degree of variability. Prevalence estimates have been calculated using birth rate, birth prevalence, and assumed survival and derived from large administrative databases. To report more robust prevalence estimate, we performed a systematic review for studies concerning CHD prevalence in adults. Moreover, to diminish bias of calculated estimates, we conducted an evidence-based calculation for the Netherlands. Methods: A systematic database search was performed to identify reports on the prevalence of adult CHD. Bicuspid aortic valve, mitral valve prolapse, Marfan syndrome, cardiomyopathy, congenital arrhythmia, and spontaneously closed defects were excluded. In addition, CHD prevalence was calculated using birth rate, birth prevalence, and survival estimates. Results: Our search yielded 10 publications on the prevalence of CHD in adults. Four reported results from population wide cross-sectional data, whereas in 6, prevalence was calculated. Mean prevalence reported by empirical studies was 3,562 per million when unspecified lesions were included and 2,297 per million when these were excluded. Mean prevalence derived from calculation was 3,536. Our calculated estimate was 3,228 per million adults. Taking these estimates as well as the limitations inherent to their derivation into consideration, the prevalence of CHD in the adult population is approximately 3,000 per million adults. Conclusion: This systematic review presents a comprehensive overview of publications on the prevalence of CHD in adults. The best available evidence suggests that overall prevalence of CHD in the adult population is in the region of 3,000 per million. [ABSTRACT FROM AUTHOR]

Objective: Management of pulmonary atresia with intact ventricular septum is challenging and depends on the severity of right ventricular hypoplasia. Clinical outcomes of biventricular repair seem favorable to univentricular palliation, but data on superiority of biventricular repair regarding exercise capacity are conflicting. We investigated the response to physical and pharmacologic stress in patients with surgically corrected pulmonary atresia with intact ventricular septum. Methods: Sixteen patients (7 patients after univentricular palliation, age 11.8 ± 2.6 years; 7 patients after biventricular repair, age 12.9 ± 2.7 years; and 2 patients after 1.5 ventricular repair, age 12 and 19 years) underwent cardiopulmonary exercise test, dobutamine stress magnetic resonance imaging, and delayed contrast-enhanced magnetic resonance imaging. Results: The univentricular group showed impaired exercise capacity in contrast with normal exercise capacity in the biventricular group. Left ventricular ejection fraction increased in both groups. With dobutamine, left ventricular stroke volume increased only in the biventricular group (+11.3 ± 5.0 mL, P < .001) and not in the univentricular group (−0.04 ± 3.6 mL, P = .9). Heart rate increase was inadequate in the univentricular group. Maximum oxygen consumption and oxygen pulse were strongly correlated with left ventricular stroke volume during stress but not at rest. The results of the 2 patients after 1.5 ventricular repair were comparable to those of the univentricular group. No myocardial fibrosis was detected. Conclusions: Impaired exercise capacity in children and adolescents with pulmonary atresia with intact ventricular septum after univentricular palliation is related to decreased cardiac reserve and inadequate chronotropic response. Young patients with pulmonary atresia with intact ventricular septum after biventricular repair show normal exercise capacity and cardiac reserve. [Copyright &y& Elsevier]

Background: In women with corrected tetralogy of Fallot (ToF), pregnancy is associated with maternal cardiac, obstetric, and offspring complications. Our aim is to investigate the magnitude and determinants of pregnancy outcome in women with corrected ToF. Methods: In this retrospective international multicenter study using 2 congenital heart disease registries, 204 women with corrected ToF were identified. Within this group, 74 women had 157 pregnancies, including 30 miscarriages and 4 terminations of pregnancy. Detailed information on each completed pregnancy (n = 123) was obtained using medical records and supplementary interviews. Results: Cardiovascular events occurred during 10 (8.1%) pregnancies, mainly (supra)ventricular arrhythmias. Obstetric and offspring events occurred in 73 (58.9%) and 42 (33.9%) pregnancies, respectively, including offspring mortality in 8 (6.4%). The most important predictor was use of cardiac medication before pregnancy (odds ratio for cardiac events 11.7, 95% CI 2.2-62.7; odds ratio for offspring events 8.4, 95% CI 1.4-48.6). In pregnancies with cardiovascular events, significantly more small-for-gestational-age children were born (P value < .01). Conclusions: Cardiovascular, obstetric, and offspring events occur frequently during pregnancies in women with ToF. Maternal use of cardiovascular medication is associated with pregnancy outcome, and maternal cardiovascular events during pregnancy are highly associated with offspring events.

Background: Previous studies demonstrated that ventricular response to stress cardiovascular magnetic resonance (CMR) is frequently abnormal in patients with a systemic right ventricle (RV). However, the clinical implications of these findings remained unknown. We sought to evaluate whether abnormal response to stress CMR predicts adverse outcome in patients with a systemic RV. Methods: Thirty-nine adult patients (54% male; mean age 26, range 18-65 years) with a systemic RV underwent stress CMR to determine the response of RV volumes and ejection fraction (EF). During follow-up, cardiac events, defined as hospitalization for heart failure, cardiac surgery, aborted cardiac arrest, or death, were recorded. The prognostic value of an abnormal response to stress, defined as lack of a decrease in RV end-systolic volume (ESV) or lack of an increase in RV EF, was assessed. Results: We frequently observed an abnormal response to stress, as RV ESV did not decrease in 17 patients (44%), and RV EF did not increase in 15 patients (38%). After a mean follow-up period of 8.1 years, 8 (21%) patients had reached the composite end point. The inability to decrease RV ESV during stress was predictive for cardiac events with a hazard ratio of 2.3 (95% CI 1.19-88.72, P = .034), as was the inability to increase RV EF with a hazard ratio of 2.3 (95% CI 1.31-81.59, P = .027). Conclusions: Stress CMR potentially has important prognostic value in patients with a systemic RV. Patients with a systemic RV who show abnormal cardiac response to stress have a substantially higher risk of adverse outcome. [ABSTRACT FROM AUTHOR]

Background: Angiotensin II receptor blockers have been proven to be beneficial in left ventricular failure. In patients with a morphologic right ventricle supporting the systemic circulation, its efficacy has not yet been established. Methods: We designed a multicenter, prospective, randomized, double-blind, placebo-controlled trial studying the effect of valsartan in patients with a systemic right ventricle due to a congenitally or surgically corrected transposition of the great arteries. The primary end point is the change in right ventricular ejection fraction as measured by cardiovascular magnetic resonance or multidetector row cardiac computed tomography in case of pacemaker patients. Conclusion: This large prospective, double-blind, randomized, placebo-controlled trial will establish the role of angiotensin II receptor blockers (valsartan) in the treatment of patients with a systemic right ventricle.

Abstract: Vis JC, Thoonsen H, Duffels MG, de Bruin-Bon RA, Huisman SA, van Dijk AP, Hoendermis ES, Berger RM, Bouma BJ, Mulder BJ. Six-minute walk test in patients with Down syndrome: validity and reproducibility. Objectives: To examine the validity of the six-minute walk test (6MWT) as a tool to evaluate functional exercise performance in patients with Down syndrome (DS). Design: Comparison of the six-minute walk distance (6MWD) in 2 distinct groups of DS patients: with and without severe cardiac disease. To test reproducibility, a group of patients with DS performed the 6MWT twice. Setting: Tertiary referral centers for patients with congenital heart defects and outpatient clinics for people with intellectual disabilities. Participants: Adult patients with DS with (n=29) and without (n=52) severe cardiac disease categorized by cardiac echocardiography. Interventions: Not applicable. Main Outcome Measure: Distance walked on the 6MWT. Results: The mean 6MWD in the group with severe cardiac disease was 289±104m and in the group without severe cardiac disease 280±104m (P=.70). Older age, female sex, and severe level of intellectual disability were all found to be independently and significantly correlated with a lower 6MWD (r=.67, P<.001). The paired 6MWD was not significantly different (310±88m vs 317±85m; P=.40) in patients who performed the 6MWT twice. The coefficient of variation was 11%. Conclusions: The 6MWD between the 2 groups was not significantly different. However, the walking distance inversely correlated with the level of intellectual disability. Therefore, the 6MWT is not a valid test to examine cardiac restriction in adult patients with DS. [Copyright &y& Elsevier]

Background: Data on long-term response to bosentan in adults and especially children with pulmonary arterial hypertension (PAH) associated with systemic-to-pulmonary shunt are scarce. Methods: We studied bosentan efficacy in 30 patients (20 adults, 10 children) with the disease at short- (4 months), and long-term follow-up (through 2.7 years). World Health Organization functional class (WHO class), transcutaneous oxygen saturation, and 6-minute walk distance were assessed at baseline, 4 months, 1 year, 1.5 years, and at latest follow-up (median 2.7 years). Results: At baseline, children tended to have more severe disease compared with adults with regard to WHO class and congenital heart defects. At 4 months'' follow-up, WHO class and 6-minute walk distance significantly improved in both adults and children. During long-term follow-up, this improvement persisted through 1 year but declined thereafter in the total group. In the children, a progressive decline in exercise capacity was observed from 1-year follow-up, whereas in the adults, improvement lasted longer. No change from baseline was seen in transcutaneous oxygen saturation. Three (10%) patients died, 2 (7%) discontinued bosentan, and 5 (17%) required additional PAH therapy (of whom 1 eventually died). One- and 2-year persistence of beneficial bosentan effect was 68% and 43% (total group), 78% and 57% (adults), and 50% and 20% (children), respectively. Conclusions: Our experience with bosentan suggests short-term improvement in both adults and children with PAH associated with systemic-to-pulmonary shunt. At long-term follow-up, a progressive decline in beneficial bosentan effect was observed. The decline appeared most pronounced in the pediatric patients, who, in this study, tended to have more severe disease at baseline. [Copyright &y& Elsevier]

Abstract: Survival of patients with aortic coarctation has dramatically improved after surgical repair became available and the number of patients who were operated and reach adulthood is steadily increasing. However, life expectancy is still not as normal as in unaffected peers. Cardiovascular complications are frequent and require indefinite follow-up. Concern falls chiefly in seven categories: recoarctation, aortic aneurysm formation or aortic dissection, coexisting bicuspid aortic valve, endocarditis, premature coronary atherosclerosis, cerebrovascular accidents and systemic hypertension. In this review, these complications, with particular reference to late hypertension, are discussed and strategies for the clinical management of post-coarctectomy patients are described.

The findings of this case report suggest that quantitative assessment of plasma neurohormones and magnetic resonance imaging functional parameters in patients with right ventricular pressure overload due to chronic pulmonary embolism might be used as indicators for right ventricular function before and after intervention. Monitoring of changes in these parameters may provide quantitative follow-up of right ventricular function in these patients. [Copyright &y& Elsevier]

Background: Many patients with congenital heart disease have persistent cardiac defects, psychosocial adjustment problems, and a poor quality of life. This study tested the relationship between negative thoughts and adaptation to congenital heart disease. Methods: Eighty-two adult out-Patients with congenital heart disease were divided on the basis of few, moderate or many negative thoughts. Group differences were tested in medical and psychosocial adjustment variables (including negative emotions), and quality of life. Results: Patients with many negative thoughts scored worse on psychosocial adjustment and quality of life, irrespective of severity of cardiac deviation, according to the cardiologist, New York Heart Association classification, number of passed and expected surgery, or use of medication. Conclusion: Negative affect in general, rather than negative thoughts is decisive in psychosocial adjustment and quality of life. Psychological intervention would be helpful for many patients.

Background. Failure of the systemic right ventricle (RV) often complicates adult survival in unoperated or physiologically repaired congenitally corrected transposition of the great arteries (CCTGA). Healthy controls schematically represent an optimal outcome of anatomic repair, which is increasingly performed to treat CCTGA. Magnetic resonance imaging dobutamine stress testing measures cardiac reserve, and sets to compare the left ventricle of controls with the systemic RV of unoperated and physiologically repaired patients with CCTGA.Methods. Baseline and stress magnetic resonance imaging (maximum dobutamine dose, 15 μg/kg/min) assessed systemic RV function in 13 minimally or asymptomatic adult patients with CCTGA (unoperated, n = 7; physiologically repaired, n = 6). The left ventricles of 11 healthy age-matched adults served as controls.Results. Baseline and stress end-diastolic volumes were similar between the systemic RV of unoperated patients and the left ventricle of controls, as well as base line end-systolic volumes. Stress ejection fraction was lower in unoperated and physiologically repaired patients (70 ± 6% and 60 ± 5%, respectively, vs healthy controls (84 ± 8%). However, comparable with healthy controls, both subsets of CCTGA patients responded appropriately to dobutamine stress, as illustrated by similar RV stroke volume, heart rate, mean blood pressure, and cardiac index.Conclusions. Compared with the left ventricles of healthy controls, both patient groups had larger systemic RV volumes, diminished ejection fraction, but an appropriate response to dobutamine stress. Values of unoperated patients are closer to normal than physiologically repaired patients. Magnetic resonance imaging dobutamine may help to define the subgroups of CCTGA patients with favorable anatomy, whereby asymptomatic adult survival could be anticipated without the need for an operation.

Little is known about the course of echocardiographic parameters used for the evaluation of valvular heart disease (VHD) during pregnancy, hampering interpretation of possible changes (physiological vs. pathophysiological). Therefore we studied the course of these parameters and ventricular function in pregnant women with aortic and pulmonary VHD. The cohort comprised 66 pregnant women enrolled in the prospective ZAHARA studies or evaluated by an identical protocol who had pulmonary VHD or aortic VHD (stenosis/prosthetic valve). The control group comprised 46 healthy pregnant women. Echocardiography was performed preconception, during pregnancy and 1 year postpartum. Peak gradient, mean gradient, aortic valve area (AVA)/effective orifice area (EOA), left ventricular ejection fraction (LVEF) and right ventricular function (RVF; TAPSE) were assessed. Peak and mean gradients increased during pregnancy compared to preconception in women with aortic VHD and controls (p < 0.0125), but not in women with pulmonary VHD. AVA/EOA remained unchanged. Preconception and postpartum gradients were comparable in all groups. Mean LVEF was normal in pregnant women with VHD and controls. Mean TAPSE was lower (p < 0.001) in women with pulmonary VHD compared to women with aortic VHD and controls (<20 mm vs. ≥23 mm; p < 0.001). In women with pulmonary VHD a decrease of TAPSE was observed during pregnancy (p = 0.005). Physiological changes during pregnancy lead to increased Doppler gradients in women with aortic VHD. This increase was not found in women with pulmonary VHD, probably caused by impaired RVF. Therefore, evaluation of RVF during pregnancy might be important to prevent underestimation of the degree of stenosis. • Serial changes in Doppler gradients and valve area in aortic and pulmonary valve disease were reported throughout pregnancy • Aortic valve gradients increased during pregnancy and returned to baseline postpartum, valve area remained unchanged • Valve gradients did not change in pregnant women with pulmonary valve disease, likely due to worse right ventricular function • Evaluation of the right ventricle might be important to prevent possible underestimation of the degree of pulmonary stenosis [ABSTRACT FROM AUTHOR]
