B-type natriuretic peptide levels predict long-term mortality in a large cohort of adults with congenital heart disease.

BACKGROUND AND AIMS: Many adult patients with congenital heart disease (ACHD) are still afflicted by premature death. Previous reports suggested natriuretic peptides may identify ACHD patients with adverse outcome. The study investigated prognostic power of B-type natriuretic peptide (BNP) across the spectrum of ACHD in a large contemporary cohort. METHODS: The cohort included 3392 consecutive ACHD patients under long-term follow-up at a tertiary ACHD centre between 2006 and 2019. The primary study endpoint was all-cause mortality. RESULTS: A total of 11 974 BNP measurements were analysed. The median BNP at baseline was 47 (24-107) ng/L. During a median follow-up of 8.6 years (29 115 patient-years), 615 (18.1%) patients died. On univariable and multivariable analysis, baseline BNP [hazard ratio (HR) 1.16, 95% confidence interval (CI) 1.15-1.18 and HR 1.13, 95% CI 1.08-1.18, respectively] and temporal changes in BNP levels (HR 1.22, 95% CI 1.19-1.26 and HR 1.19, 95% CI 1.12-1.26, respectively) were predictive of mortality (P < .001 for both) independently of congenital heart disease diagnosis, complexity, anatomic/haemodynamic features, and/or systolic systemic ventricular function. Patients within the highest quartile of baseline BNP (>107 ng/L) and those within the highest quartile of temporal BNP change (>35 ng/L) had significantly increased risk of death (HR 5.8, 95% CI 4.91-6.79, P < .001, and HR 3.6, 95% CI 2.93-4.40, P < .001, respectively). CONCLUSIONS: Baseline BNP and temporal BNP changes are both significantly associated with all-cause mortality in ACHD independent of congenital heart disease diagnosis, complexity, anatomic/haemodynamic features, and/or systolic systemic ventricular function. B-type natriuretic peptide levels represent an easy to obtain and inexpensive marker conveying prognostic information and should be used for the routine surveillance of patients with ACHD.

Cor triatriatum dexter associated with atrial septal defect: Management in a complex clinical case.

The coexistence of an atrial septal defect and a prominent eustachian valve is a rare congenital anomaly, rarely reported in literature. Differentiation between a giant eustachian valve and cor triatriatum dexter can be difficult. A case of a large atrial septal defect associated with cor triatriatum dexter diagnosed by echocardiography in an asymptomatic woman is reported. A watchful waiting strategy was adopted.

Pregnancy in patients with the Fontan operation.

Improved survival rates for patients with a Fontan circulation has allowed more women with this complex cardiac physiology to contemplate pregnancy. However, pregnancy in women with a Fontan circulation is associated with a high risk of adverse maternal and foetal outcomes, high rates of miscarriage, and preterm delivery. Factors associated with a successful pregnancy outcome are younger age, normal body weight, absence of significant functional limitation, no Fontan-related complications, and well-functioning single ventricle physiology. Appropriate care with timely preconception counselling and regular, frequent clinical reviews by a multidisciplinary team based at a tertiary centre improves the chance of a successful pregnancy. Empowerment of patients with education on their specific congenital cardiac condition and its projected trajectory helps them make informed choices regarding their health, reproductive choices, and assists them to achieve their life goals.

Pregnancy in women with Fontan is feasible but associated with a high risk of adverse maternal/foetal outcomes. Younger age, normal body weight, absence of significant functional limitation, and no Fontan-related complications are favourable factors. Timely preconception counselling and regular clinical reviews in a tertiary centre with an MDT improves pregnancy outcomes. Empowerment of patients with education helps them make informed choices on health, family planning, and the future.

Pregnancy in women with a Fontan circulation: Short and long-term outcomes.

BACKGROUND: The Fontan circulation procedure is the palliative surgery of choice for patients with single ventricle physiology, many of whom are now reaching childbearing age due to advances in care. Our study examines the impact of pregnancy on women with Fontan circulation, assessing both short and long-term outcomes. METHODS: We retrospectively analysed pregnancies in women with Fontan circulation at our centre from 2005 to 2023, including a matched non-pregnant, nulliparous cohort for comparison. Pregnancies lost before 18 weeks were analysed separately. RESULTS: Among 26 pregnancies in 18 women, preterm births were common (73.1%), with 3 fetal losses and no maternal deaths. Neonatal complications included a 50% incidence of babies small for gestational age (SGA). Cardiac events occurred in 19.2% of pregnancies, primarily supraventricular arrhythmias, and 23% experienced postpartum haemorrhage. Over a median 6.1 [5.2-10.6]-year follow-up, no deaths, heart failure (HF), or Fontan-associated liver disease (FALD) developed, and functional status remained stable. CONCLUSIONS: Women with a Fontan-type circulation undergoing pregnancy had a few serious maternal cardiac events, though there was a high rate of post-partum haemorrhage. The rates of neonatal complications, particularly related to restricted growth and pre-term birth, were also high. Our findings indicate a generally positive medium-term outlook for these patients, though the impact of pregnancy on long-term survival remains unclear. Careful selection of patients with Fontan circulation during pre-pregnancy counselling may help to reduce complications during and after pregnancy.

Complete Transposition of the Great Arteries in the Pediatric Field: A Multimodality Imaging Approach.

The complete transposition of the great arteries (C-TGA) is a congenital cardiac anomaly characterized by the reversal of the main arteries. Early detection and precise management are crucial for optimal outcomes. This review emphasizes the integral role of multimodal imaging, including fetal echocardiography, transthoracic echocardiography (TTE), cardiovascular magnetic resonance (CMR), and cardiac computed tomography (CCT) in the diagnosis, treatment planning, and long-term follow-up of C-TGA. Fetal echocardiography plays a pivotal role in prenatal detection, enabling early intervention strategies. Despite technological advances, the detection rate varies, highlighting the need for improved screening protocols. TTE remains the cornerstone for initial diagnosis, surgical preparation, and postoperative evaluation, providing essential information on cardiac anatomy, ventricular function, and the presence of associated defects. CMR and CCT offer additional value in C-TGA assessment. CMR, free from ionizing radiation, provides detailed anatomical and functional insights from fetal life into adulthood, becoming increasingly important in evaluating complex cardiac structures and post-surgical outcomes. CCT, with its high-resolution imaging, is indispensable in delineating coronary anatomy and vascular structures, particularly when CMR is contraindicated or inconclusive. This review advocates for a comprehensive imaging approach, integrating TTE, CMR, and CCT to enhance diagnostic accuracy, guide therapeutic interventions, and monitor postoperative conditions in C-TGA patients. Such a multimodal strategy is vital for advancing patient care and improving long-term prognoses in this complex congenital heart disease.

Morbidity and mortality in adults with a Fontan circulation beyond the fourth decade of life.

AIMS: To evaluate the late outcomes of adults (above 35 years) with a Fontan-type circulation, for whom current data on morbidity and mortality are lacking. METHODS AND RESULTS: Data were collected retrospectively on consecutive patients with Fontan circulation above the age of 35 years followed in three European specialist centres. Overall, 115 Fontan patients were included [median age 35 (range 35-48) years, 47.8% female]. The most common underlying congenital heart disease diagnosis was tricuspid atresia (n = 58, 50.4%), and the age at first Fontan completion was 9.1 (interquartile range 5.0-15.8) years. Almost two-thirds (61.7%) of patients had undergone an atriopulmonary Fontan, and 23.5% had received a total cavopulmonary connection. One-third required repeat surgery or intervention. Most patients (55.9%) were in New York Heart Association functional class II or class I (30.6%), 76 (66.1%) patients had experienced at least one arrhythmia, and eight (7.0%) protein-losing enteropathy. At a median follow-up of 5.0 (2.4-10.3) years, 15 (13.0%) patients were referred for transplantation assessment and 19 (16.5%) patients died, mainly from heart failure (84.2%). Univariable predictors of death or transplantation included lower serum albumin level [hazard ratio (HR) 1.09 per g/L decrease, 95% confidence interval (CI): 1.04-1.15, P = 0.0009], prior heart failure admission (HR 4.28, 95% CI:1.75-10.44, P = 0.001), prior atrial tachycardia or flutter (HR 3.02, 95% CI: 1.23-7.38, P = 0.02), and baseline pulmonary vasodilator therapy (HR 8.59, 95% CI:1.05-70.13, P = 0.04). Lower serum albumin and prior atrial tachycardia or flutter remained significant on bivariable analysis. CONCLUSION: Our study highlights the significant morbidity and mortality in older adults with a Fontan-type circulation, emphasizing the need for lifelong specialist surveillance with frequent risk stratification, close monitoring, and early consideration for transplantation assessment.

This study sheds light on the complex medical journey of adults living with the outcomes of Fontan surgery­a procedure performed in early childhood. These individuals have reached the milestone of their forties and beyond, yet they confront an array of significant health challenges that necessitate lifelong, individualized congenital heart disease care. The key findings are as follows:While adults with Fontan circulation are living longer, they are at high risk of death, mainly due to heart failure. They also face a host of other health issues, including the need for additional surgeries or interventions. Nearly two-thirds have experienced some form of heart rhythm problem, and a substantial number eventually require evaluation for a heart transplant.Heart transplants within this group were rare, which may be linked to the various barriers to transplantation in the Fontan population. Moreover, those with multiple indicators of advanced disease have a heightened risk of life-threatening events, reinforcing the critical need for personalized and continuous specialist care designed to meet their distinct health requirements.

Cardiovascular Magnetic Resonance from Fetal to Adult Life-Indications and Challenges: A State-of-the-Art Review.

Cardiovascular magnetic resonance (CMR) imaging offers a comprehensive, non-invasive, and radiation-free imaging modality, which provides a highly accurate and reproducible assessment of cardiac morphology and functions across a wide spectrum of cardiac conditions spanning from fetal to adult life. It minimises risks to the patient, particularly the risks associated with exposure to ionising radiation and the risk of complications from more invasive haemodynamic assessments. CMR utilises high spatial resolution and provides a detailed assessment of intracardiac and extracardiac anatomy, ventricular and valvular function, and flow haemodynamic and tissue characterisation, which aid in the diagnosis, and, hence, with the management of patients with cardiac disease. This article aims to discuss the role of CMR and the indications for its use throughout the different stages of life, from fetal to adult life.

Multimodality Imaging Assessment of Tetralogy of Fallot: From Diagnosis to Long-Term Follow-Up.

Tetralogy of Fallot (TOF) is the most common complex congenital heart disease with long-term survivors, demanding serial monitoring of the possible complications that can be encountered from the diagnosis to long-term follow-up. Cardiovascular imaging is key in the diagnosis and serial assessment of TOF patients, guiding patients' management and providing prognostic information. Thorough knowledge of the pathophysiology and expected sequalae in TOF, as well as the advantages and limitations of different non-invasive imaging modalities that can be used for diagnosis and follow-up, is the key to ensuring optimal management of patients with TOF. The aim of this manuscript is to provide a comprehensive overview of the role of each modality and common protocols used in clinical practice in the assessment of TOF patients.

Advanced heart failure in adult congenital heart disease: the role of renal dysfunction in management and outcomes.

AIMS: Previous studies in adult congenital heart disease (CHD) have demonstrated a link between renal dysfunction and mortality. However, the prognostic significance of renal dysfunction in CHD and decompensated heart failure (HF) remains unclear. We sought to assess the association between renal dysfunction and outcomes in adults with CHD presenting to our centre with acute HF between 2010 and 2021. METHODS AND RESULTS: This retrospective analysis focused on the association between renal dysfunction, pre-existing and on admission, and outcomes during and after the index hospitalization. Chronic kidney disease (CKD) was defined as an estimated glomerular filtration rate <60 mL/min/1.73 m2. Cox regression analysis was used to identify the predictors of death post-discharge. In total, 176 HF admissions were included (mean age 47.7 ± 14.5 years, 43.2% females). One-half of patients had a CHD of great complexity, 22.2% had a systemic right ventricle, and 18.8% had Eisenmenger syndrome. Chronic kidney disease was present in one-quarter of patients. The median length of intravenous diuretic therapy was 7 (4-12) days, with a maximum dose of 120 (80-160) mg furosemide equivalents/day, and 15.3% required inotropic support. The in-hospital mortality rate was 4.5%. The 1- and 5-year survival rates free of transplant or ventricular assist device (VAD) post-discharge were 75.4% [95% confidence interval (CI): 69.2-82.3%] and 43.3% (95% CI: 36-52%), respectively. On multivariable Cox analysis, CKD was the strongest predictor of mortality or transplantation/VAD. Highly complex CHD and inpatient requirement of inotropes also remained predictive of an adverse outcome. CONCLUSION: Adult patients with CHD admitted with acute HF are a high-risk cohort. CKD is common and triples the risk of death/transplantation/VAD. An expert multidisciplinary approach is essential for optimizing outcomes.

Renal dysfunction was associated with more advanced disease, higher diuretic doses, and a longer hospital inpatient stay. Chronic kidney disease was common and tripled the risk of death, transplantation, or ventricular assist device. Renal dysfunction in adults with congenital heart disease and heart failure should prompt intensified monitoring, optimization of medical therapy, and collaborative management with renal physicians.

Role of Cardiovascular Imaging in the Follow-Up of Patients with Fontan Circulation.

Since its first description in 1971, the Fontan procedure and its modifications have led to a substantial improvement in the survival rates of patients with a variety of types of complex Congenital Heart Disease (CHD) characterised by the presence of a single, dominant ventricle. However, despite the significant improvement of the prognosis over the years, Fontan patients are still exposed to several cardiovascular and systemic complications. It is, therefore, important to fully understand the pitfalls hidden behind a Fontan anatomy and the potential predictors of ventricular failure. Cardiovascular imaging plays a key role in this context, allowing for the early identification of complications with important prognostic implications. Echocardiography remains the first-line imaging modality for serial evaluation of Fontan patients. However, there is a growing role of cardiovascular magnetic resonance and cardiac computed tomography from pre-operative assessment to longitudinal follow-up. The aim of this paper will be to provide a comprehensive overview of the role, strengths, and weaknesses of each imaging modality in the assessment of congenital cardiac conditions palliated with the Fontan procedure.

Epidemiology and management of Staphylococcus Aureus infective endocarditis in adult patients with congenital heart disease: A single tertiary center experience.

BACKGROUND: Infective endocarditis (IE) is a potentially lethal disease for adults with congenital heart disease (ACHD). Staphylococcus aureus (SA) is one of the commonest pathogens, identified in patients with ACHD and IE. This study aims to analyse the epidemiology, clinical characteristics and in-hospital management of IE due to SA (SAIE) in ACHD. METHODS: This is a single center retrospective study on documented episodes of SAIE in ACHD patients, treated at the Royal Brompton Hospital between 1999 and February 2020. RESULTS: Thirty-seven ACHD patients had an episode of SAIE (mean age 35.5 ± 14.9 years). More than half (51.3%), had a cardiac lesion of at least moderate complexity, with left ventricular outflow tract lesions being the most frequent. Twenty-four (64.9%) patients had a history of at least one previous open-heart surgery, and prosthetic material was used in 20 patients. A predisposing event was identified in 11 episodes (29.7%). Surgery was performed during the same admission in 24 (64.9%) patients, with early surgery (≤ 7 days from admission) performed in 12 patients. Early operation was associated with a shorter in-hospital stay compared to a later operation during the same admission or medical management [28.5 (IQR 23) vs. 43.5 (IQR 30) days, P = 0.028]. In-hospital mortality was 8.1%. Renal dysfunction at admission was associated with in-hospital multiorgan complications and/or death (OR 7.50, 95% CI, 1.18-47.67, P = 0.03). CONCLUSION: SAIE remains a life-threatening complication, necessitating cardiac surgery in the majority of ACHD patients. Ongoing educational investment on prevention and timely SAIE detection is warranted.

Eisenmenger Syndrome: JACC State-of-the-Art Review.

Although major breakthroughs in the field of pediatric cardiology, cardiac surgery, intervention, and overall care improved the outlook of congenital heart disease, Eisenmenger syndrome (ES) is still encountered and remains a complex clinical entity with multisystem involvement, including secondary erythrocytosis, increased thrombotic and bleeding diathesis, high arrhythmogenic risk, progressive heart failure, and premature death. Clearly, care for ES is best delivered in multidisciplinary expert centers. In this review, we discuss the considerable recent progress in understanding the complex pathophysiology of ES, means of prognostication, and improvement in clinical outcomes achieved with pulmonary arterial hypertension-targeted therapies. Additionally, we delineate areas of uncertainty in various aspects of care, discuss gaps in current evidence, and review current status in less privileged countries and propose initiatives to reduce disease burden. Finally, we propose the application of emerging technologies to enhance the delivery and quality of health care related to ES and beyond.

Myocardial fibrosis in asymptomatic patients undergoing surgery for mitral and aortic valve regurgitation.

BACKGROUND: Chronic heart valve regurgitation induces left ventricular (LV) volume overload, leading to the development of hypertrophy and progressive dilatation of the ventricle to maintain physiological cardiac output. In order to prevent potential irreversible LV structural changes, the identification of the best timing for treatment is pivotal. OBJECTIVE: To assess the presence and extent of fibrosis in myocardial tissue in asymptomatic patients with valvular heart disease (VHD) and preserved LV dimensions and function undergoing cardiac surgery. METHODS: Thirty-nine patients were enrolled. Sixteen patients were affected by aortic or mitral regurgitation: they were all asymptomatic, undergoing valve surgery according to VHD European Society of Cardiology guidelines. Twenty-three patients with end-stage nonischemic dilated cardiomyopathy (DCM) and severe LV dysfunction undergoing cardiac surgery for implantation of a durable left ventricular assist device (LVAD) served as controls. During surgery, VHD patients underwent three myocardial biopsies at the level of the septum, the lateral wall and LV apex, while in LVAD patients the coring of the apex of the LV was used. For both groups, the tissue samples were analyzed on one section corresponding to the apical area. All slides were stained with hematoxylin and eosin and Masson's trichrome staining and further digitalized. The degree of fibrosis was then calculated as a percentage of the total area. RESULTS: Of 39 patients, 23 met the inclusion criteria: 12 had mitral or aortic insufficiency with a preserved ejection fraction and 11 had idiopathic dilated cardiomyopathy. Quantitative analysis of apical sections revealed a myocardial fibrosis amount of 10 ±â€Š6% in VHD patients, while in LVAD patients the mean apical myocardial fibrosis rate was 38 ±â€Š9%. In VHD patients, fibrosis was also present in the lateral wall (9 ±â€Š4%) and in the septum (9 ±â€Š6%). CONCLUSION: Our case series study highlights the presence of tissue remodeling with fibrosis in asymptomatic patients with VHD and preserved LV function. According to our results, myocardial fibrosis is present at an early stage of the disease, well before developing detectable LV dysfunction and symptoms. Since the relationship between the progressive magnitude of myocardial fibrosis and potential prognostic implications are not yet defined, further studies on this topic are warranted.

Resting cardiac energy metabolism is inversely associated with heart rate in healthy young adult men.

BACKGROUND: 31-Phosphorus-magnetic resonance spectroscopy may provide pathophysiological insights into the high-energy phosphate metabolism of the myocardium as measured by phosphocreatine to adenosine triphosphate (PCr/ATP) ratio. Aim of the present study was to determine in vivo the relation between cardiac PCr/ATP ratio and heart rate in normal male subjects. METHODS: One hundred twelve apparently healthy, young male individuals (age 34 ± 10 years) were prospectively evaluated. They underwent cardiac cine magnetic resonance imaging to assess left ventricular (LV) function and morphology and 3D-ISIS (31)P-magnetic resonance spectroscopy of the LV to assess the PCr/ATP ratio (a recognized in vivo marker of myocardial energy metabolism). Data were analyzed after segregation by tertiles of the resting PCr/ATP ratio. RESULTS: A significant inverse association between PCr/ATP ratios and resting heart rate was observed (Spearman ρ: r=-0.37; P < .0001). PCr/ATP ratios were also inversely associated with body mass index, diastolic blood pressure, wall mass and with insulin resistance, but in multiple regression analysis heart rate was found to be independently related to PCr/ATP. CONCLUSIONS: The present study shows that resting heart rate is proportionally lower across tertiles of increasing PCr/ATP ratio of the LV in apparently healthy young male individuals, supporting the hypothesis that heart rate is a major determinant of cardiac energy stores. These findings may explain the prognostic role of heart rate in the general population as evidenced by previous large epidemiological studies.

[Present trends and controversies in the use of beta-blockers in cardiovascular diseases]. / Beta-bloccanti e sistema cardiovascolare: attuali acquisizioni e controversie.

In this paper we summarize present trends and controversies in the use of beta-blockers in cardiovascular diseases. Beta-blockers are catecolamine competitive inhibitors and act through alpha and beta adrenergic receptors blockade. Different agents have a dose-dependent affinity for different beta adrenergic receptors (beta 1, beta 2, beta 3) which is less with higher doses. The most important therapeutic effects of beta-blockers are on cardiovascular system, where they act as negative chronotropic and inotropic agents, lowering cardiac work and improving oxygen demand /supply ratio. Clinical indications are numerous. For their anti-ischemic activity beta-blockers are used as anti-anginal drugs and in acute and previous myocardial infarction for preventing total and cardiovascular mortality. Combined use of beta-blockers and ACE inhibitors slows down heart failure progression and reduces cardiovascular mortality. Beta-blockers are useful in treating focal atrial tachycardia and supra ventricular paroxysmal tachycardia, by reducing sinus node automaticity and delay atrio-ventricular conduction; they also prevent sudden cardiac death and ventricular tachycardia associated with increased sympathetic activity. There is no indication in treating primary non-complicated hypertension with beta-blockers as first-line drugs. Different metabolic effects of selective and non-selective beta-blockers are actually debated. In conclusion, beta-blockers have indication in the treatment of many cardiovascular diseases. Further studies are needed for better understanding the differences in cardiac and peripheral beta-blockers effects depending on their selectivity.

Three-Dimensional Late Gadolinium Enhancement Cardiovascular Magnetic Resonance Predicts Inducibility of Ventricular Tachycardia in Adults With Repaired Tetralogy of Fallot.

BACKGROUND: Adults with repaired tetralogy of Fallot die prematurely from ventricular tachycardia (VT) and sudden cardiac death. Inducible VT predicts mortality. Ventricular scar, the key substrate for VT, can be noninvasively defined with late gadolinium enhancement (LGE) cardiovascular magnetic resonance but whether this relates to inducible VT is unknown. METHODS: Sixty-nine consecutive repaired tetralogy of Fallot patients (43 male, mean 40±15 years) clinically scheduled for invasive programmed VT-stimulation were prospectively recruited for prior 3-dimensional LGE cardiovascular magnetic resonance. Ventricular LGE was segmented and merged with reconstructed cardiac chambers and LGE volume measured. RESULTS: VT was induced in 22 (31%) patients. Univariable predictors of inducible VT included increased RV LGE (odds ratio [OR], 1.15; P=0.001 per cm3), increased nonapical vent LV LGE (OR, 1.09; P=0.008 per cm3), older age (OR, 1.6; P=0.01 per decile), QRS duration ≥180 ms (OR, 3.5; P=0.02), history of nonsustained VT (OR, 3.5; P=0.02), and previous clinical sustained VT (OR, 12.8; P=0.003); only prior sustained VT (OR, 8.02; P=0.02) remained independent in bivariable analyses after controlling for RV LGE volume (OR, 1.14; P=0.003). An RV LGE volume of 25 cm3 had 72% sensitivity and 81% specificity for predicting inducible VT (area under the curve, 0.81; P<0.001). At the extreme cutoffs for ruling-out and ruling-in inducible VT, RV LGE >10 cm3 was 100% sensitive and >36 cm3 was 100% specific for predicting inducible VT. CONCLUSIONS: Three-dimensional LGE cardiovascular magnetic resonance-defined scar burden is independently associated with inducible VT and may help refine patient selection for programmed VT-stimulation when applied to an at least intermediate clinical risk cohort.

Long-term mortality and cardiovascular burden for adult survivors of coarctation of the aorta.

OBJECTIVE: To examine the contemporary long-term outcome after coarctation repair. METHODS: This is a retrospective cohort study of 834 patients aged ≥16 years who underwent coarctation repair under single-centre follow-up. Repair was performed at a median age of 3 years (lower-upper quartile: 1 month to 15 years) by surgery in 83% (690/834) and angioplasty/stenting in 17% (144/834). Survival was compared with an age- and gender matched normal population. Other outcomes included arch reintervention, aortic valve intervention, ascending aortic intervention, and residual/re-coarctation and resting hypertension at latest follow-up. RESULTS: After a median follow-up of 27 years (lower-upper quartile: 18-36), there were 38 late deaths (5%, 38/834). Overall survival was 99%, 88% and 65% at 30, 50 and 70 years of age, respectively, significantly reduced compared with a matched normal population (standardised mortality ratio: 3.20, log-rank: p<0.001). Thirty per cent (246/834) required ≥1 arch reintervention, 13% (111/834) an aortic valve intervention and 5% (43/834) an ascending aortic intervention. Freedom from aortic valve and ascending aortic intervention was 83% and 92% at 50 years and 53% and 81% at 70 years of age, respectively. Residual/re-coarctation (gradient ≥25 mm Hg or repair site/diaphragm ratio ≤70%) at latest follow-up was present in 60% (282/474) and resting hypertension in 57% (379/661). CONCLUSIONS: Long-term survival in contemporary adult survivors of coarctation repair is significantly lower than a matched normal population with accelerated decline after the third decade. Nearly 60% of patients eventually develop hypertension, whereas approximately 50% require further invasive cardiovascular treatment by 50 years of age. Our risk-stratifying data may enable personalised follow-up strategies for this common congenital heart condition.
