Blood Biomarkers Predict 10-Year Clinical Outcomes in Adult Patients With Congenital Heart Disease.

Background: The adult congenital heart disease (ACHD) population is growing and risk prediction is important to predict adverse outcome and consult patients during their lifecourse. Objectives: This study aims to describe the long-term prognostic value of blood biomarkers in ACHD. Methods: In this prospective observational cohort study, 602 patients with moderate or complex ACHD were included (median age 32.5 years [IQR: 24.7-41.2], 42% female, 90% New York Heart Association I). N-terminal pro-brain natriuretic peptide (NT-proBNP), high-sensitive-troponin T, growth differentiation factor 15, high-sensitive-C-reactive protein, suppression of tumorigenicity-2 and galectin-3, as well as full blood count, renal function, LDL, and HDL were measured. Cox models were applied to relate the selected biomarkers with the primary end point of all-cause mortality and secondary end point of mortality or heart failure. Standardized HRs adjusted for relevant prognostic factors, including age, sex, and complexity of diagnosis, were reported. Results: Abnormal biomarker levels were present in 424 (70.4%) patients. During a median follow-up of 10.1 years, 41 (6.8%) patients died and 81 (13.5%) developed heart failure. Associations were observed between the primary and secondary end point and red cell distribution width, NT-proBNP, and growth differentiation factor 15. In a multibiomarker model, only NT-proBNP remained associated with mortality (HR: 2.74; 95% CI: 2.01-3.74). NT-proBNP significantly improved the C-statistic of the clinical prediction model (0.85-0.92). Based on NT-proBNP alone, low-risk patients could be identified. Patients with NT-proBNP <76 ng/L showed a 10-year heart failure-free survival of 98.5%. Conclusions: Blood biomarkers have prognostic value in ACHD. NT-proBNP improves risk prediction and is able to identify low-risk patients. Its routine use should be implemented in ACHD.

Prognostic value of the electrocardiogram in patients with bicuspid aortic valve disease.

BACKGROUND: Identifying bicuspid aortic valve (BAV) patients at risk for cardiac events remains challenging and the role of the electrocardiogram (ECG) has not yet been described. Therefore, this study aims to describe ECG parameters in BAV patients, and investigate their prognostic value. METHODS: In this single-center prospective study patients with BAV without a prior aortic valve replacement (AVR) were included. Transthoracic echocardiogram and 12­lead resting-ECG were obtained. Associations between ECG parameters and the composite endpoint of all-cause mortality and AVR were assessed using Cox-proportional hazard analysis. RESULTS: 120 patients with BAV were included (median age 30 years, 61% male). Median aortic jet velocity was 2.4 m/s [IQR: 1.7-3.4] and 5 patients (4%) had severe aortic regurgitation. All patients were in sinus rhythm. Any ECG abnormality was present in 57 patients (48%). Median PR-interval was 156 [IQR: 138-170] msec. A deviating QRS axis was found in 17 patients (14%) and Cornell criteria for LVH were fulfilled in 20 patients (17%). Repolarization abnormalities were present in 12 patients (10%). Median follow-up duration was 7.0 [6.3-9.8] years, during which 23 patients underwent AVR and 2 patients died. After adjusting for age, a longer PR-interval was associated with worse intervention-free survival (HR 1.02, 95% CI: 1.01-1.04). CONCLUSION: Almost half of the patients with BAV had abnormalities on their ECG. Moreover, the PR-interval may be an interesting prognostic marker for intervention-free survival in BAV patients.

Inoperable chronic thromboembolic pulmonary hypertension: Evolution of prognosis over 10 years of new emerging therapies.

Therapies for inoperable chronic thromboembolic pulmonary hypertension (CTEPH) include balloon pulmonary angioplasty (BPA) and PH-specific medical therapy. This study compares survival and its predictors before and after the introduction of BPA. BPA was independently associated with survival; however, there was no difference in overall survival between the two cohorts.

Blood and Imaging Biomarkers in the Long-term Follow-up of Bicuspid Aortic Valve Patients.

Background: Bicuspid aortic valve (BAV) is a common congenital heart defect. Patients with BAV are at risk for long-term complications such as valve stenosis and regurgitation. This study aimed to investigate sex differences in blood and imaging biomarkers and to describe the long-term prognostic value of blood and echocardiographic biomarkers. Methods: Patients were included from 2 prospective observational cohort studies; they underwent venous blood sampling and transthoracic echocardiography including speckle tracking. Analyzed blood biomarkers were red-cell distribution width (RDW), creatinine, C-reactive protein (CRP), troponin T, N-terminal pro B-type natriuretic peptide (NT-proBNP), and transforming growth factor-beta (TGF-ß). Sex differences were analyzed at baseline. Associations between biomarkers and arrhythmia-free and intervention-free survival were determined by Cox regression, adjusted for age and sex. Results: A total of 182 patients with BAV were included: median age 34; interquartile range [IQR]: 23-46 years; 55.5% male. CRP, NT-proBNP, and RDW were higher in women, whereas creatinine, troponin T and TGF-ß were higher among men. After a median follow-up time of 6.9 (IQR: 6.5-9.9) years, arrhythmia-free and intervention-free survival was, 81.0% and 73.1%, respectively. NT-proBNP was associated with both arrhythmia-free and intervention-free survival (hazard ratio [HR], 1.94, P = 0.005 and HR, 2.06, P = 0.002, respectively). On echocardiography higher left atrial (LA) size, left ventricular end-diastolic diameter (LVEDD), left ventricular (LV) mass index and E/e' ratio were associated with lower arrhythmia-free survival, whereas higher LA size, LV mass index, aortic valve peak velocity, and aortic regurgitation were associated with lower intervention-free survival. Conclusions: Differences were observed in blood biomarkers between men and women with BAV. Besides LV systolic parameters, diastolic LV function and NT-proBNP should have a more prominent role as prognostic markers in clinical care.

Contexte: La bicuspide valvulaire aortique (BVA) est une anomalie cardiaque congénitale fréquente. Les patients atteints d'une BVA présentent des risques de complications à long terme, comme la sténose valvulaire ou la régurgitation valvulaire. Cette étude visait 1) à évaluer les différences entre les sexes en ce qui concerne les biomarqueurs sanguins et les biomarqueurs à l'imagerie; et 2) à décrire la valeur pronostique à long terme des biomarqueurs sanguins et échocardiographiques. Méthodologie: Des patients de 2 études de cohortes observationnelles prospectives ont été inclus dans l'analyse. Des échantillons de sang veineux ont été prélevés, et des échocardiographies transthoraciques, y compris le suivi des marqueurs acoustiques, ont été effectuées. Les biomarqueurs sanguins analysés étaient les suivants : indice de distribution des globules rouges (IDR), créatinine, protéine C-réactive (CRP), troponine T, propeptide natriurétique de type B N-terminal (NT-proBNP) et facteur de croissance transformant ß (TGF-ß). Les différences entre les sexes ont été analysées au départ. Les liens entre les biomarqueurs et la survie sans arythmie et sans intervention ont été déterminés par la régression de Cox, avec correction en fonction de l'âge et du sexe. Résultats: Cent quatre-vingt-deux patients présentant une BVA étaient inclus (âge médian de 34 [écart interquartile : 23-46] ans, 55,5 % hommes). La CRP, la NT-proBNP et l'IDR étaient plus élevées chez les femmes, alors que la créatinine, la troponine T et le TGF-ß étaient plus élevés chez les hommes. Après une période de suivi médiane de 6,9 (écart interquartile : 6,5-9,9) ans, les taux de survie sans arythmie et sans intervention étaient respectivement de 81,0 % et de 73,1 %. La NT-proBNP a été associée à la survie sans arythmie (rapport des risques instantanés [RRI] : 1,94, p = 0,005) et à la survie sans intervention (RRI : 2,06, p = 0,002). À l'échocardiographie, des valeurs élevées pour la taille de l'oreillette gauche, le diamètre télédiastolique du ventricule gauche (VG), l'indice de masse du VG et le rapport E/e' étaient associées à un faible taux de survie sans arythmie, alors que des valeurs élevées pour la taille de l'oreillette gauche, l'indice de masse du VG, la vitesse maximale aortique et la régurgitation aortique étaient associées à un faible taux de survie sans intervention. Conclusions: Les biomarqueurs sanguins variaient en fonction du sexe des personnes présentant une BVA. Outre les paramètres systoliques du VG, la fonction VG diastolique et la NT-proBNP devraient être davantage utilisées comme marqueurs pronostiques en soins cliniques.

Heart rate: an accessible risk indicator in adult congenital heart disease.

BACKGROUND: Higher resting heart rate has been described as a risk factor for adverse outcome in healthy individuals and cardiovascular patients. The aim of this study was to evaluate resting heart rate as risk factor in adult congenital heart disease (ACHD). METHODS: In this prospective observational cohort study, patients with moderate or complex ACHD were included at routine outpatient visit. Standard 12-lead ECGs were obtained in rest. Heart rate was obtained from the ECG automatically by the Modular ECG Analysis System (MEANS). The primary endpoint was all-cause mortality and the secondary endpoint was a composite of all-cause mortality and heart failure. Survival was derived using the Kaplan-Meier estimator. Subgroups based on heart rate tertiles were compared by the log-rank test. Cox proportional hazards models were adjusted for clinical factors including age, sex and diagnosis (moderate vs complex ACHD). RESULTS: A total of 556 patients were included (median age 32 years (IQR 24-41), 57.6% male). Mean heart rate was 69±13 bpm. Negative chronotropic medication was used by 74 (13.3%) patients. During a median follow-up of 10.1 (IQR 9.6-10.5) years, 36 patients (6.5%) died and 83 (14.9%) reached the secondary endpoint. Patients with higher heart rates had significantly lower survival and heart failure-free survival. After adjusting for clinical factors, heart rate remained associated with mortality (HR 1.57 per 10 bpm, 95% CI 1.26 to 1.96) and mortality or heart failure (HR 1.33 per 10 bpm, 95% CI 1.13 to 1.57). CONCLUSION: Higher heart rate is associated with lower survival and heart failure-free survival in ACHD.

Long term outcome after surgical ASD-closure at young age: Longitudinal follow-up up to 50 years after surgery.

OBJECTIVES: To describe the clinical outcome and quality of life up to 50 years after surgical atrial septal defect (ASD) closure at young age. Primary outcome is defined as MACE (all-cause mortality, cardiac re-interventions, ischemic stroke, endocarditis, heart failure and symptomatic arrhythmia). METHODS: Single-center, longitudinal cohort-study evaluating 135 consecutive patients who underwent ASD-closure before the age of 15 years between 1968 and 1980. Participants were invited for extensive cardiac evaluation and assessment of quality-of-life every 10 years. RESULTS: Eighty patients (86%) of 93 eligible survivors were included in this study (mean age 52 ± 5 years (range 41-63), 40% male). Median follow-up since surgery was 45 years (range 40-51). Cumulative survival after 50 years was 86% and comparable to the normal Dutch population. Cumulative event-free survival after 45 and 50-years was 59% and 46% respectively (re-intervention in 6, symptomatic arrhythmia in 25, and pacemaker implantation in 10 patients). Right ventricular ejection fraction on CMR was diminished in 6%. Exercise capacity was normal in 77%. There was no pulmonary hypertension. NT-proBNP was elevated in 61%. Quality of life was comparable with the general population. No predictors for late events were identified. CONCLUSION: Long-term survival after surgical ASD-closure in childhood is good and not statistically different at 50 years compared to the normal Dutch population. Re-intervention rate is low, there is no pulmonary hypertension. Right ventricular function was diminished in 6%, exercise capacity was good and stable over time with quality of life comparable to the general population. However, supraventricular tachycardia is common.

End-stage heart failure in congenitally corrected transposition of the great arteries: a multicentre study.

BACKGROUND AND AIMS: For patients with congenitally corrected transposition of the great arteries (ccTGA), factors associated with progression to end-stage congestive heart failure (CHF) remain largely unclear. METHODS: This multicentre, retrospective cohort study included adults with ccTGA seen at a congenital heart disease centre. Clinical data from initial and most recent visits were obtained. The composite primary outcome was mechanical circulatory support, heart transplantation, or death. RESULTS: From 558 patients (48% female, age at first visit 36 ± 14.2 years, median follow-up 8.7 years), the event rate of the primary outcome was 15.4 per 1000 person-years (11 mechanical circulatory support implantations, 12 transplantations, and 52 deaths). Patients experiencing the primary outcome were older and more likely to have a history of atrial arrhythmia. The primary outcome was highest in those with both moderate/severe right ventricular (RV) dysfunction and tricuspid regurgitation (n = 110, 31 events) and uncommon in those with mild/less RV dysfunction and tricuspid regurgitation (n = 181, 13 events, P < .001). Outcomes were not different based on anatomic complexity and history of tricuspid valve surgery or of subpulmonic obstruction. New CHF admission or ventricular arrhythmia was associated with the primary outcome. Individuals who underwent childhood surgery had more adverse outcomes than age- and sex-matched controls. Multivariable Cox regression analysis identified older age, prior CHF admission, and severe RV dysfunction as independent predictors for the primary outcome. CONCLUSIONS: Patients with ccTGA have variable deterioration to end-stage heart failure or death over time, commonly between their fifth and sixth decades. Predictors include arrhythmic and CHF events and severe RV dysfunction but not anatomy or need for tricuspid valve surgery.

Life expectancy and end-of-life communication in adult patients with congenital heart disease, 40-53 years after surgery.

Aims: Although survival of patients with congenital heart disease (CHD) improved significantly over time, life expectancy is still not normal. We aimed to investigate how adult patients, their partners, and treating cardiologists estimated the individual life expectancy of CHD patients. Furthermore, preferences regarding end-of-life (EOL) communication were investigated. Methods and results: In this study, we included 202 patients (age: 50 ± 5) who were operated in childhood (<15 years old) between 1968 and 1980 for one of the following diagnoses: atrial septal defect, ventricular septal defect, pulmonary stenosis, tetralogy of Fallot, or transposition of the great arteries. A specific questionnaire was administered to both the patients and their partners, exploring their perceived life expectancy and EOL wishes. Two cardiologists independently assessed the life expectancy of each patient. Most adults with CHD believed their life expectancy to be normal. However, significant differences were found between estimated life expectancy by the cardiologist and patients (female: P = 0.001, male: P = 0.002) with moderate/severe defects, as well as for males with mild defects (P = 0.011). Regarding EOL communication, 85.1% of the patients reported that they never discussed EOL with a healthcare professional. Compared with patients with mild CHD, significantly more patients with moderate/severe defect discussed EOL with a physician (P = 0.011). The wish to discuss EOL with the cardiologist was reported by 49.3% of the patients and 41.7% of their partners. Conclusion: Adult patients, especially with moderate/severe CHD, perceived their life expectancy as normal, whereas cardiologists had a more pessimistic view than their patients. Increased attention is warranted for discussions on life expectancy and EOL to improve patient-tailored care.

SCUBA Diving in Adult Congenital Heart Disease.

Conventionally, scuba diving has been discouraged for adult patients with congenital heart disease (ACHD). This restrictive sports advice is based on expert opinion in the absence of high-quality diving-specific studies. However, as survival and quality of life in congenital heart disease (CHD) patients have dramatically improved in the last decades, a critical appraisal whether such restrictive sports advice is still applicable is warranted. In this review, the cardiovascular effects of diving are described and a framework for the work-up for ACHD patients wishing to engage in scuba diving is provided. In addition, diving recommendations for specific CHD diagnostic groups are proposed.

Role of the electrocardiogram in the risk stratification of pulmonary hypertension.

INTRODUCTION: The prognosis of pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) remains dismal. Better risk prediction is needed. This study investigated the prognostic value of ECG characteristics. METHODS: In this single-centre prospective study, consecutive treatment-naïve patients with PAH or CTEPH were included at time of diagnosis. From the 12-lead ECG, obtained at baseline, the following parameters were collected: heart rate (HR), rhythm, QRS axis, conduction times, P-top amplitudes in II, R-top and S-wave amplitudes in V1 and V5 and repolarisation disorders. Associations between the ECG and transplant-free survival was assessed by Kaplan-Meier curves and Cox-proportional hazard regressions. RESULTS: In total, 140 patients were included (median age: 60.7 years, 63.6% female). The ECG was abnormal in 86.2%: sinus rhythm was not present in 9.3%, right QRS axis was observed in 47.8%, mean QRS duration was 101±17 ms. Only 42.5% of the patients had normal repolarisation, 34.5% had right ventricular strain and 14.4% non-specific repolarisation disorders. Over a median follow-up time of 3.49 (IQR: 1.37-6.42) years, 45 patients (32.5%) died or underwent lung transplantation. Transplant-free survival was worse in patients presenting with an abnormal ECG (64.0% vs 86.0%; p=0.037). The following ECG characteristics were associated with all-cause mortality or lung transplantation: heart rate (HR 1.02, 95% CI: 1.00 to 1.05), QRS duration >120 ms (HR 2.61, 95% CI: 1.01 to 6.71) and S-wave amplitude in V5 (HR 1.10, 95% CI: 1.04 to 1.17). CONCLUSION: Only 13.8% of patients with PAH and CTEPH presented with a normal ECG, which is associated with favourable outcome. The ECG provides additional prognostic value to current clinical parameters and should be considered in risk prediction.

Comparison of advanced echocardiographic right ventricular functional parameters with cardiovascular magnetic resonance in adult congenital heart disease.

Aims: Advanced transthoracic echocardiography (TTE) using volumetric and deformational indices provides detailed quantification of right ventricular (RV) function in adults with congenital heart disease (ACHD). Two-dimensional multi-plane echocardiography (2D-MPE) has demonstrated regional wall differences in RV longitudinal strain (LS). This study aims to evaluate the association of these parameters with cardiovascular magnetic resonance (CMR). Methods and results: One-hundred stable ACHD patients with primarily affected RVs were included (age 50 ± 5 years; 53% male). Conventional and advanced echocardiographic RV functional parameters were compared with CMR-derived RV function. Advanced echocardiographic RV functional parameters were measurable in approximately one-half of the study cohort, while multi-wall LS assessment feasibility was lower. CMR RV ejection fraction (CMR-RVEF) was moderately correlated with deformational, area, and volumetric parameters [RV global LS (lateral wall and septum), n = 55: r = -0.62, P < 0.001; RV wall average LS, n = 34: r = -0.49, P = 0.002; RV lateral wall LS, n = 56: r = -0.45, P < 0.001; fractional area change, n = 67: r = 0.48, P < 0.001; 3D-RVEF, n = 48: r = 0.40, P = 0.005]. Conventional measurements such as TAPSE and RV S' correlated poorly. RV global LS best identified CMR-RVEF < 45% (area under the curve: 0.84, P < 0.001: cut-off value -19%: sensitivity 100%, specificity 57%). RVEF and LS values were significantly higher when measured by CMR compared with TTE (mean difference RVEF: 5 [-9 to 18] %; lateral (free) wall LS: -7 [7 to -21] %; RV global LS: -6 [5 to -16] %) while there was no association between respective LS values. Conclusion: In ACHD patients, advanced echocardiographic RV functional parameters are moderately correlated with CMR-RVEF, although significant differences exist between indices measurable by both modalities.

The evolution of survival of pulmonary arterial hypertension over 15 years.

The prognosis of pulmonary arterial hypertension (PAH) remains dismal. Over the years, multiple therapeutic advances have been introduced. This study evaluates the evolution of PAH survival over the past 15 years. We included 293 consecutive adult patients diagnosed with PAH between 2005 and 2019 (median age: 61.8 years, 70.3% female). Patients were divided into three cohorts based on the time of diagnosis: 2005-2009, 2010-2014, and 2015-2019 (2005-2009: n = 56; 2010-2014: n = 111; 2015-2019: n = 126). Transplant-free survival was measured from the date of right heart catheterization until patients reached the composite endpoint of lung transplant or death. Multivariable cox-pulmonary hypertension regression was used to study the effect of the time of diagnosis. The final cox model was fitted in both younger and older patients to evaluate the difference between these groups. During a median follow-up time of 4.1 (interquartile range: 2.2-7.3) years, 9 patients underwent lung transplantation and 151 patients died. The median overall transplant-free survival was 6.2 (5.5-8.0) years. Patients older than 56 years at baseline who were diagnosed in 2005-2009 showed better survival compared to patients diagnosed in 2010-2014 and 2015-2019 with an adjusted hazard ratio of, respectively, 2.12 (1.11-4.03) and 2.83 (1.41-5.69). Patients younger than 56 years showed neither an improved nor deteriorated survival over time. In conclusion, survival in patients with PAH did not improve over time, despite more available therapeutic options. This might be partly due to the changed demographic characteristics of the PAH patients and a still important diagnostic delay.

Long-Term Outcomes After Atrial Switch Operation for Transposition of the Great Arteries.

BACKGROUND: For patients with d-loop transposition of the great arteries (d-TGA) with a systemic right ventricle after an atrial switch operation, there is a need to identify risks for end-stage heart failure outcomes. OBJECTIVES: The authors aimed to determine factors associated with survival in a large cohort of such individuals. METHODS: This multicenter, retrospective cohort study included adults with d-TGA and prior atrial switch surgery seen at a congenital heart center. Clinical data from initial and most recent visits were obtained. The composite primary outcome was death, transplantation, or mechanical circulatory support (MCS). RESULTS: From 1,168 patients (38% female, age at first visit 29 ± 7.2 years) during a median 9.2 years of follow-up, 91 (8.8% per 10 person-years) met the outcome (66 deaths, 19 transplantations, 6 MCS). Patients experiencing sudden/arrhythmic death were younger than those dying of other causes (32.6 ± 6.4 years vs 42.4 ± 6.8 years; P < 0.001). There was a long duration between sentinel clinical events and end-stage heart failure. Age, atrial arrhythmia, pacemaker, biventricular enlargement, systolic dysfunction, and tricuspid regurgitation were all associated with the primary outcome. Independent 5-year predictors of primary outcome were prior ventricular arrhythmia, heart failure admission, complex anatomy, QRS duration >120 ms, and severe right ventricle dysfunction based on echocardiography. CONCLUSIONS: For most adults with d-TGA after atrial switch, progress to end-stage heart failure or death is slow. A simplified prediction score for 5-year adverse outcome is derived to help identify those at greatest risk.

Supraventricular arrhythmia in pregnancy.

The physiological changes during pregnancy predispose a woman for the development of new-onset or recurrent arrhythmia. Supraventricular arrhythmia is the most common form of arrhythmia during pregnancy and, although often benign in nature, can be concerning. We describe three complex cases of supraventricular arrhythmia during pregnancy and review the currently available literature on the subject. In pregnancies complicated by arrhythmia, a plan for follow-up and both maternal and fetal monitoring during pregnancy, delivery and post partum should be made in a multidisciplinary team. Diagnostic modalities should be used as in non-pregnant women if there is an indication. All antiarrhythmic drugs cross the placenta, but when necessary, medical treatment should be used with consideration to the fetus and the mother's altered pharmacodynamics and kinetics. Electrical cardioversion is safe during pregnancy, and electrophysiological study and catheter ablation can be performed in selected patients, preferably with zero-fluoroscopy technique. Sometimes, delivering the fetus (if viable) is the best therapeutic option. In this review, we provide a framework for the workup and clinical management of supraventricular arrhythmias in pregnant women, including cardiac, obstetric and neonatal perspectives.

Clinical outcome of anomalous coronary artery with interarterial course in adults: Single-center experience combined with a systematic review.

BACKGROUND: Anomalous coronary artery originating from the opposite sinus of Vasalva with interarterial course (ACAOS-IAC) is associated with sudden cardiac death (SCD) in young athletes. If identified in adulthood prognosis is usually more benign, resulting in a dilemma regarding revascularization. METHODS: This is a retrospective observational single-center study, including adults with ACAOS-IAC. Medical records between 2012 and 2019 were reviewed for management approach, mortality, cardiac death and coronary related adverse events. Coronary computed tomographic angiography (CCTA) were reviewed. We provide a literature review in regard to clinical outcome. RESULTS: We identified 40 patients with ACAOS-IAC (mean age 51). Presentation was acute in 7/40 (18%). Ischemia detection with single photon emission tomography (SPECT), cardiac magnetic resonance (CMR) or dobutamine stress echocardiography were performed in 25/40 (63%) patients. Ischemia in the vascular territory of the anomaly was present in 2/25 (8%). In 39/40 (98%) patients were treated expectative. During median follow-up of 2.7 years (IQR 1.5-5.3) no cardiovascular death was observed. Mortality occurred in 1/40 (3%) and coronary related adverse events in 2/40 (5%). We identified 20 studies describing 1194 patients. Revascularization was performed in 376/1154 (32.6%) patients. Mortality stratified for clinical management was 23/431 (5.3%) in the non-revascularization versus 16/253 (6.3%) in the revascularization group during 4.0 years follow-up (weighted median). Cause of death was cardiovascular in 10/596 (1.7%) in 4.2 years (weighted median) follow up. CONCLUSIONS: Both revascularization and non-invasive management have good prognosis in adults with ACAOS-IAC during early follow up. There is need for guidelines and long-term surveillance.

Quantitative assessment of the entire right ventricle from one acoustic window: An attractive approach in patients with congenital heart disease in daily practice.

BACKGROUND: Right ventricular (RV) function is recognized as an important prognostic factor in adult congenital heart disease (ACHD). The accuracy of established parameters including tricuspid annular plane systolic excursion (TAPSE), RV fractional area change (RVFAC) and tissue Doppler imaging (TDI S') is limited as only a small RV region is reflected. We previously introduced a novel four-view approach with different RV walls visualized from one apical view using electronic plane rotation, also known as iRotate. AIM: To evaluate the entire RV function using electronic plane rotation echocardiography within the spectrum of ACHD compared with healthy subjects. METHODS AND RESULTS: One hundred and forty-two ACHD patients were recruited from the outpatient clinic and 89 healthy subjects. All subjects underwent a transthoracic echocardiogram with evaluation of TAPSE, TDI S' and peak systolic longitudinal RV strain (RV-LS) from all RV walls using the four-view electronic plane rotation model. With exception of TDI S' in inferior coronal view, all parameters were lower in ACHD vs healthy subjects (p < 0.001). Within the ACHD patients, RV strain was lower in anterior (-15.9 ± 4.9) and inferior coronal view (-15.1 ± 4.5) versus lateral (-17.6 ± 5.0) and inferior wall (-17.2 ± 4.7) (p < 0.05). RV-LS values of systemic RV were lower (p < 0.05), but no difference was observed between subpulmonic RV loading conditions. CONCLUSION: The four-view electronic plane rotation model represents a reproducible, easily applicable and complete RV assessment in daily practice. RV function is significantly decreased in the ACHD group using both regional and global assessment parameters. Complete RV strain analysis reveals regional differences.

Prognostic value of C-reactive protein in adults with congenital heart disease.

BACKGROUND: High-sensitivity C reactive protein (hs-CRP) has been associated with outcomes in adult congenital heart disease (ACHD). However, its prognostic value beyond N-terminal pro B type natriuretic peptide (NT-proBNP) or troponin T remains unknown. We studied the temporal evolution of hs-CRP, as well as the relation between hs-CRP and adverse clinical outcomes independent of NT-proBNP and troponin T in patients with ACHD. METHODS: In this prospective cohort study, we enrolled 602 patients with ACHD (2011-2013) who underwent baseline and thereafter annual blood sampling during 4 years. Hs-CRP, hs-troponin T and NT-proBNP were measured. The primary endpoint was composed of death or heart failure (HF). Cox regression and Joint Modelling was used to relate 2log hs-CRP levels with the endpoint, with adjustment for baseline characteristics and (repeated) hs-troponin T and NT-proBNP measurements. RESULTS: Hs-CRP was measured at baseline in 591 patients, median age 33 years, 58% men, 90% New York Heart Association I with an average of 4.3 measurements per patient. Median follow-up was 5.9 (IQR 5.3-6.3) years (99.2% complete) and 69 patients met the endpoint. Higher baseline hs-CRP was independently associated with higher risk of death or HF (HR 1.36, 95% CI 1.19 to 1.55). Hs-CRP increased over time prior to death or HF, and repeated hs-CRP measurements were associated with the endpoint, independent of repeated NT-proBNP and hs-troponin T (HR 1.54, 95% CI 1.24 to 1.98). CONCLUSIONS: Hs-CRP carries incremental prognostic value for the risk of death or HF, beyond NT-proBNP and hs-troponin T. Hs-CRP increased prior to the occurrence of HF or death, supporting the role of inflammation in the clinical deterioration of patients with ACHD.

Health-related quality of life and lived experiences in males and females with thoracic aortic disease and their partners.

OBJECTIVE: Thoracic aortic disease (TAD) may have substantial impact on health-related quality of life (HRQOL). We described HRQOL in patients with TAD, cardiovascular screening participants and their partners; identified factors associated with HRQOL; and explored lived experiences and feelings of anxiety or depression using a mixed methods design. METHODS: For this cross-sectional study, all consecutive patients visiting the TAD outpatient clinic (2017-2019) at our centre were asked to complete three questionnaires: the Short Form 36 (SF-36), the Hospital Anxiety and Depression Scale (HADS) and the Rotterdam Disease Specific Questionnaire (RDSQ). A subsample was invited for in-depth interviews. RESULTS: In total, 261 participants were included: 147 patients with TAD (thoracic aortic diameter ≥40 mm; 54 females, 36.7%), 114 screening participants (cardiovascular family screening; 71 females, 62.3%) and 66 partners. Compared with the general population, patients with TAD showed markedly lower HRQOL, whereas screening participants' HRQOL was less impaired. Female and younger participants scored significantly lower on the SF-36 and HADS compared with male and older participants. Smaller aortic diameter was associated with better RDSQ score, and previous aortic surgery was associated with higher HADS depression scores. Furthermore, partners scored significantly lower on 2/8 SF-36 subdomains when compared with the general population. From 11 interviewees, determinants of psychological distress included coping strategies, impact on social and professional life, disease-related knowledge, state of aortic diameters and physical symptoms. CONCLUSIONS: Healthcare professionals must be aware of HRQOL impairments in patients with TAD, particularly in younger females. Moreover, attention for partners is needed. Coping strategies and communication within the family were found to be important factors influencing psychological distress, and might be valuable leads for counselling and HRQOL improvement in this population.
