RESUMEN
Rates of successful surgical repair and life expectancy for patients with congenital heart disease have increased dramatically in recent decades. Thanks to advances in diagnosis, treatment, and follow-up care, an ever-increasing number of individuals with congenital heart disease are reaching advanced age. The exposure to cardiovascular risk factors during their lifetime is modifying the outlook and late clinical trajectory of adult congenital heart disease (ACHD). Their disease burden is shifting from congenital to acquired, primarily atherosclerotic cardiovascular disease (ASCVD) with worrisome consequences. In addition, the complex background of ACHD often curbs appropriate preventive strategies by general practitioners or adult cardiologists. Comprehensive guidance for the prevention and management of acquired heart disease in ACHD patients is currently not available, as this topic has not been covered by the European Society of Cardiology (ESC) guidelines on cardiovascular disease prevention or the ESC guidelines for the management of ACHD. In this document, a state-of-the-art overview of acquired heart disease in ACHD patients and guidance on ASCVD prevention for both ACHD specialists and non-ACHD cardiologists are provided. The aim is to provide a clinical consensus statement to foster the development of a sustainable strategy for the prevention of ASCVD in a practical and simple-to-follow way in this ever-growing cardiovascular cohort, thus reducing their cardiovascular burden.

BACKGROUND: Long-term data on COVID-19 vaccine safety, immunogenicity, and acceptance in adults with CHD are lacking. METHODS: This is a prospective study including adults with CHD patients undergoing COVID-19 vaccination from January 2021 to June 2022. Data on adverse events, antispike IgG titre, previous or subsequent COVID-19 infection, booster doses, and patients' attitude towards vaccination were collected. RESULTS: Four hundred and ninety CHD patients (36 ± 13 years, 53% male, 94% with moderate/complex defects) were prospectively included: 433 (88%) received a Pfizer-BioNTech mRNA vaccine, 31 (6%) Moderna mRNA vaccine, 23 (5%) AstraZeneca-Oxford ChAdOx1 nCov-19 vaccine, and 3 (0.6%) Janssen Vaccine; 310 (63%) received a booster dose. Median follow-up after vaccination was 1.53 [1.41-1.58] years. No major adverse event was reported. Eighty-two fully vaccinated patients contracted COVID-19 during follow-up after a median of 5.4 [4.3-6.5] months from the last dose. One patient with Ebstein's disease died from severe COVID-19. Symptoms' duration in patients who tested positive after vaccination was significantly shorter than in the group tested positive before vaccination (5.5 [3-8] versus 9 [2.2-15] days, p = 0.04). Median antispike IgG titre measured in 280 individuals (57%) at a median of 1.4 [0.7-3.3] months from the last dose was 2381 [901-8307] BAU/ml. Sixty patients (12%) also showed positive antinucleocapsid antibodies, demonstrating previous SARS-COV2 exposure. Twenty-nine percent appeared to have concerns regarding vaccine safety and 42% reported fearing potential effects of the vaccine on their cardiac disease before discussing with their CHD cardiologist. CONCLUSION: COVID-19 vaccines appear safe in the mid-term follow-up in adults with CHD with satisfactory immunogenicity and reduction of symptoms' duration in case of infection.

BACKGROUND: Wearable cardioverter-defibrillators (WCDs) are currently used in patients at temporarily heightened risk for sudden cardiac death (SCD) who are temporarily unable to receive an implantable cardioverter-defibrillator (ICD). WCD can safely record and terminate life-threatening arrhythmias through a non-invasive electrode-based system. The current clinical indications for WCD use are varied and keep evolving as experience with this technology increases. METHODS: We reviewed and explored the data behind indications for WCD use and discuss its usefulness in congenital heart disease (CHD) patients. RESULTS: We considered 8 consecutive patients (mean age 35.25 years, range 18-51 years, average duration of WCD use 4 months, range 3-6 months) with complex CHD, in which a WCD was used between June 2018 and January 2022. No sustained ventricular arrhythmias requiring shocks were recorded in the observation period. No inappropriate shocks were recorded. All the patients showed a good compliance and a very high mean wear time per day (21.2 ± 1 h a day). Four patients implanted a permanent device (3 CRT-D, 1 ICD), three underwent cardiac surgery at the end of the WCD period and one is still on the waiting list for the operation. CONCLUSIONS: Larger trial could confirm the possible conceivable benefit from an extended use of the WCD in certain populations with complex CHD as in our case series, especially in patients with life-treating ventricular arrhythmias waiting for surgery for residual cardiac defects or in the early phases following the surgical/hemodynamic interventions, patients with tachycardiomyopathy expected to improve after the arrhythmias are removed and patients awaiting implantation of an ICD at high risk due to active infection.
RESUMEN
BACKGROUND: Adults with CHD are known to greatly benefit from a prompt access to continuous expert care. On the other hand, coronavirus disease 2019 pandemic has determined a dramatic worldwide reconfiguration of the healthcare systems, with rapid redeployment of resources towards this emergency. Italy was the first Western country affected by a large-scale spread of coronavirus disease 2019. The aim of our study is to analyse the impact of the coronavirus disease 2019 outbreak on in-hospital care of patients with CHD in an Italian tertiary centre. METHODS AND RESULTS: We retrospectively reviewed data on CHD hospital admissions in our centre since 1 March, 2020, when the adoption of a strict infection containment policy throughout the country resulted in limited access of patients to routine hospital care and resources reallocation to the care of infected patients. Comparison with data from the previous year was performed in order to identify any relevant differences attributable to the outbreak. Despite cancellation of all elective procedures, the overall number of urgent hospital admission remained stable throughout the period of study. Patients admitted during the pandemic had greater disease complexity (p = 0.001) with longer length of in-hospital stay (p = 0.01). No adverse events or positive swabs were reported among CHD patients who were admitted to hospital or medical personnel caring for these patients. CONCLUSION: Data from our early experience suggest that coronavirus disease 2019 pandemic did not impact significantly on the provision of urgent care to adult patients with CHD.

BACKGROUND: Eisenmenger syndrome is associated with substantial morbidity and mortality. There is no consensus, however, on mortality risk stratification. We aimed to investigate survival and predictors of death in a large, contemporary cohort of Eisenmenger syndrome patients. METHODS: In a multicenter approach, we identified adults with Eisenmenger syndrome under follow-up between 2000 and 2015. We examined survival and its association with clinical, electrocardiographic, echocardiographic, and laboratory parameters. RESULTS: We studied 1098 patients (median age, 34.4 years; range, 16.1-84.4 years; 65.1% female; 31.9% with Down syndrome). The majority had a posttricuspid defect (n=643, 58.6%), followed by patients with a complex (n=315, 28.7%) and pretricuspid lesion (n=140, 12.7%). Over a median follow-up of 3.1 years (interquartile range, 1.4-5.9), allowing for 4361.6 patient-years observation, 278 patients died and 6 underwent transplantation. Twelve parameters emerged as significant predictors of death on univariable analysis. On multivariable Cox regression analysis, only age (hazard ratio [HR], 1.41/10 years; 95% confidence interval [CI], 1.24-1.59; P<0.001), pretricuspid shunt (HR, 1.56; 95% CI, 1.02-2.39; P=0.041), oxygen saturation at rest (HR, 0.53/10%; 95% CI, 0.43-0.65; P<0.001), presence of sinus rhythm (HR, 0.53; 95% CI, 0.32-0.88; P=0.013), and presence of pericardial effusion (HR, 2.41; 95% CI, 1.59-3.66; P<0.001) remained significant predictors of death. CONCLUSIONS: There is significant premature mortality among contemporary adults with Eisenmenger syndrome. We report, herewith, a multivariable mortality risk stratification model based on 5 simple, noninvasive predictors of death in this population.

Transvenous pacemaker (PM) catheters can be unintentionally placed in the left ventricle (LV) during the implantation procedure. An 8-year-old girl was discovered with a malpositioned pm wire, seven years after the implant. Trans-thoracic echocardiogram revealed the lead traversing the inter-atrial septum, crossing the mitral valve and embedded in the basal lateral wall of the LV. This is a report of a 14-year long follow-up after the surgical extraction of the malpositioned PM lead.

One of the major complications of radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF) is pulmonary vein stenosis (PVS). The natural history of PVS, especially when it involves more than one vein, leads to severe and irreversible pulmonary hypertension with end-stage right heart failure that can require, in extreme cases, even heart-lung transplantation. We report the case of a young patient who underwent RFCA for a single lasting episode of AF and developed PVS years later. He was treated with ballon venoplasty followed by stent implantation in left pulmonary vein because of PVS relief. This reported case emphasizes the need of an adequate indication for RFCA for AF, considering the benefit-risk ratio especially in young patients with normal cardiac function.

Thromboembolic complications occur frequently in Fontan patients with atrial arrhythmias and are a cause of significant morbidity and all-cause mortality. We report the case of an adult woman with direct atriopulmonary connection and atrial arrhythmia who developed a right atrial thrombus. She was switched to apixaban therapy because of echocardiographic evidence of thrombus progression despite combined therapy with warfarin and aspirin. After 1 year of treatment, there was evidence of complete thrombus resolution, in the absence of bleeding events. Our case shows that direct oral anticoagulants can be effective and safe for the treatment of thrombosis in adult patients with complex CHD.

The right ventricle (RV) can be described in terms of 3 components: the inlet, the apex, and the infundibulum. In the normal adult, the RV shows an arrangement suited for pumping blood against low resistance, with a mass about one sixth that of left ventricle (LV) mass, and a larger volume than the LV. The RV is able to manage a progressive increase in the afterload by increasing contractility and remodeling. The gold standard measurement of contractility is maximal elastance (Emax), or the ratio between end-systolic pressure (ESP) and end-systolic volume (ESV), and the best measurement of afterload is arterial elastance (Ea), or the ratio between ESP and stroke volume (SV). The ratio Emax/Ea defines RV-arterial coupling. The optimal energy transfer from the RV to the pulmonary circulation is measured at Emax/Ea ratios of 1.5-2. In the presence of pulmonary hypertension, the SV/ESV ratio may be an acceptable surrogate of Emax/Ea. The right atrium (RA) has 3 anatomical components: the appendage, the venous part, and the vestibule. It is a dynamic structure having different functions: reservoir, conduit, and booster pump function. In case of increased afterload, the RA is enlarged, denoting high RA pressure, as a consequence of elevated RV diastolic pressure. RA area is a strong predictor of adverse clinical outcome in pulmonary arterial hypertension. In patients with severe pulmonary hypertension, in several congenital heart diseases, and in Eisenmenger syndrome, symptoms and prognosis are greatly dependent on RV function and its ability to adapt to a chronic increase in afterload.

To evaluate biventricular mechanics by means of echo-derived myocardial work (MW) analysis in patients with a systemic right ventricle (sRV). Comprehensive echo data were collected in all patients with a sRV who underwent transthoracic echocardiography at our tertiary centre between 2020 and 2021 including sRV function indices, global longitudinal strain (GLS) of right and left ventricle (RV/LV), biventricular MW, and atrial strain in those with congenitally corrected transposition of the great arteries (ccTGA). Fifty-six patients (37 [30.97-45.87]years, 59% male) and 49 healthy individuals matched per age and sex were included for comparison. Global work index (GWI:1106 [869.80-1293.10] Vs 314.2 [281.5-358.2]mmHg%, p < 0.0001) and global constructive work(GCW: 1542.50 [1338.9-1718.50] Vs 416.4 [365.70-464]mmHg%, p < 0.0001) were both increased for sRV compared to normal RV, reflecting exposition to a systemic afterload, with a contemporary raise in wasted work (GWW:197 [138.50-322.20] Vs 26.09 [17.80-43.48]mmHg%, p < 0.0001) and impaired efficiency (GWE:89 [83-93.54] Vs 93.67 [91.67-96] %, p < 0.0001). Conversely, sRV showed reduced MW indices in comparison to normal LV(p < 0.0001 for all). Non-systemic LV demonstrated normal GLS values (19.51 ± 3.9%), but reduced GWI (479 [368-665] Vs 2172 [1978-2386]mmHg%, p < 0.0001) and GCW (708 [490-815]mmHg% Vs 86.5 [59.25-118], p < 0.0001). Nevertherless, non-systemic LV showed also impaired efficiency (91 [88-94] Vs 95 [94-97]%, p < 0.0001). LVGLS values were related to RVGLS (R = 0.5, p = 0.00019), suggesting a consistent interventricular dependency. Atrial strain could be assessed in 16 out of 20 (80%) patients with ccTGA: both atria had reduced strain values compared to their normal counterparts. Moreover, pulmonary atrial strain during the reservoir phase was related to LVGWE (R = 0.58, p = 0.047) and inversely related to LVGLS (R = - 0.71, p = 0.0043). MW analysis is feasible in sRV and may provide additional clinical data. In our cohort MW revealed biventricular impairment, in particular for non-systemic LV, in spite of normal GLS values.

Background: Infective endocarditis (IE) is a major issue during follow-up of adults with congenital heart disease (ACHD), leading to significant mortality. Case summary: A 37-year-old woman with transposition of great arteries and previous Mustard operation developed a drug-resistant pneumonia shortly after a pacemaker implant procedure performed at a local hospital. After referral to the ACHD centre, the patient was diagnosed with multivalvular IE with biventricular involvement by methicillin-resistant Staphylococcus aureus. On admission, the patient was already in acute respiratory distress and presented both systemic and pulmonary embolization. Despite adequate treatment was promptly started, the patient developed multiorgan failure. Discussion: This case depicts a particularly aggressive of infective endocarditis forms caused with biventricular involvement and multiple embolization. Patients with congenital heart disease are at high risk of IE with adverse impact on the prognosis. Early recognition and treatment are the keys to improve prognosis. Therefore, suspicion should be high, especially following invasive procedure, which should be preferably performed at ACHD specialized centres.
RESUMEN
BACKGROUND: Sacubitril/valsartan was demonstrated to reduce hospitalization rate and mortality in patients with heart failure with reduced ejection fraction. Data on the effects of sacubitril/valsartan in patients with a systemic right ventricle are still lacking. METHODS: Patients with transposition of the great arteries following Senning/Mustard procedure or congenitally corrected transposition of the great arteries with impaired systemic right ventricle systolic function were prospectively included. Primary end points included sacubitril/valsartan safety and efficacy. Primary efficacy end points were NT-proBNP (N-terminal pro-B-type natriuretic peptide) and systolic function improvement. Secondary end points included New York Heart Association class, 6-minute walking distance, and quality of life change. RESULTS: Fifty patients (38±12 years, 60% male, 35% congenitally corrected transposition of the great arteries) were included and followed for 1 year. No major adverse events occurred. Two (4%) patients ceased treatment due to hypotension and 1 (2%) developed a nephrotic syndrome. The target dose was reached in 20 (42%) patients. NT-proBNP values decreased significantly immediately after treatment initiation, while returned to baseline at 1 year. Echocardiography showed progressive fractional area change increase (29.2±5.8 versus 34.9±5.1%; P<0.001), and right ventricle global longitudinal strain (-13.9 [-15.1, -11.8] versus -15.3 [-17.2, -13.4]%; P<0.001) and free-wall global longitudinal strain (-14.3 [-17.3, -12.3] versus -17.2 [-19.3, -15.8]%; P<0.001) raise, whereas tricuspid regurgitation severity improved only in transposition of the great arteries patients (P=0.006). Moreover, 3-dimensional echocardiography demonstrated right ventricle volumes reduction (end-diastolic volume: 181±63 versus 156±50 mL; P=0.002; end-systolic volume: 117±48 versus 89±33 mL; P<0.001), and significantly increased systemic right ventricle ejection fraction (35.6±8.1 versus 41.5±7.5%; P<0.001). Clinical improvement was suggested by New York Heart Association class change (P<0.001), increased 6-minute walking distance (425 [333, 480] versus 500 [443, 560] m; P<0.001) as well as improved quality of life at 1-year follow-up. Beneficial effects were observed irrespective of the underlying anatomy and were more pronounced in those on target dose. CONCLUSIONS: Our data showed that sacubitril/valsartan is well tolerated and is associated with systemic right ventricle remodeling and improved systolic function as well as improved clinical status, supporting its use in this complex population.

RESUMEN
AIM: To analyze left ventricular (LV) mechanics through advanced echocardiography, including speckle tracking analysis and myocardial work (MW) in a cohort of adults with repaired aortic coarctation (CoA). METHODS: Data on standard echocardiography, LV speckle-tracking and MW analysis were collected in CoA patients > 18 years with no significant recoartation or valvular disease and normal LV ejection fraction at the time of the exam. MW indices were calculated using the blood pressure measured in the right arm. A group of healthy subjects with comparable sex, age and body surface area was included for comparison. RESULTS: Eighty-nine CoA patients and 70 healthy subjects were included. Patients had higher systolic blood pressure (p < 0.0001), LV mass index (p < 0.0001), left atrial volume index (p = 0.005) and E/E' ratio (p = 0.001). Despite similar LV ejection fraction, speckle tracking analysis revealed lower global longitudinal strain (GLS: - 18.3[17-19] vs - 20.7[19-22]%, p < 0.0001) and increased peak systolic dispersion (PSD: 45[40-54] vs 37.5[32-43] ms, p < 0.0001) in CoA patients. Global work index (GWI) and global constructive work were similar to healthy controls (p = 0.6 and 0.5, respectively), whereas CoA patients showed significant increased wasted work (GWW: 125[90-185] vs 89.5[64-127]mmHg%, p < 0.0001) and a mild but significant reduction in global work efficiency (GWE: 93%[92-95] vs 95%[94-97], p < 0.0001). Moreover, when stratifying for GLS values, MW analysis showed increased GWW and PSD with impaired GWE in 54(61%) patients with normal GLS compared to healthy individuals. Spearman's linear method illustrated an inverse relation between GWE and PSD (r: - 0.53, p < 0.0001), while GCW was associated with peak (r: 0.2, p = 0.01) and mean gradient across the descending aorta (r: 0.3, p = 0.004) and with systolic blood pressure (r: 0.48, p < 0.0001). PSD was the sole univariate predictor of GWE on linear regression analysis (ß: - 0.1 [- 0.16 to - 0.07], p < 0.0001), whereas female sex, SBP and gradients across the descending aorta were independently associated with higher GCW values. When CoA patients were divided based on the history of redo CoA repair and arterial hypertension, no significant differences in MW indices were found. CONCLUSIONS: MW is a novel echocardiographic tool, which provides additional information on LV performance in CoA patients over GLS allowing a more comprehensive understanding of LV dysfunction mechanisms in a setting of increased afterload.

Wolff-Parkinson-White Syndrome (WPW) has been associated with reduced local myocardial deformation, and when left ventricular dysfunction is present, catheter ablation of the accessory pathway may be required, even in asymptomatic patients. We aimed to evaluate the diagnostic value of non-invasive myocardial work in predicting subtle abnormalities in myocardial performance in children with WPW.Seventy-five paediatric patients (age 8.7 ± 3.5 years) were retrospectively recruited for the study: 25 cases with manifest WPW and 50 age- and sex- matched controls (CTR). Global myocardial work index (MWI) was measured as the area of the left ventricle (LV) pressure-strain loops. From MWI, global Myocardial Constructive Work (MCW), Wasted Work (MWW), and Work Efficiency (MWE) were estimated. In addition, standard echocardiographic parameters of LV function were evaluated. Despite normal LV ejection fraction (EF) and global longitudinal strain (GLS), children with WPW had worse MWI, MCW, MWW, and MWE. At multivariate analysis, MWI and MCW were associated with GLS and systolic blood pressure, and QRS was the best independent predictor of low MWE and MWW. In particular, a QRS > 110 ms showed good sensitivity and specificity for worse MWE and MWW values. In children with WPW, myocardial work indices were found significantly reduced, even in the presence of normal LV EF and GLS. This study supports the systematic use of myocardial work during the follow-up of paediatric patients with WPW. Myocardial work analysis may represent a sensitive measure of LV performance and aid in decision-making.

Adults with congenital heart disease (ACHD) are frequently affected by thyroid diseases (TDs). However, the clinical relevance of TD in ACHD remains unknown. We aimed to describe the prevalence of TD in the ACHD population and to ascertain whether TD are associated with worse outcome. Patients with ACHD >18 years attending our tertiary center for a day-case between 2014 and 2019 were included. Clinical data between patients' first visit and December 2020 were collected. Primary end point was a combination of death, hospitalization for heart failure (HF), and new-onset of arrhythmic events. Secondary end points were each part of the primary outcome as separate end points. A total of 495 patients with ACHD (32.2 [24.5 to 45.6] years; 54% women) were included. Median follow-up was 9.4 (4.5 to 13.1) years. The prevalence of TD was 30%. TD group showed worse clinical status, as demonstrated by N-terminal pro b-type natriuretic peptide values (243.5 [96.5 to 523] vs 94 [45 to 207] pg/ml, p <0.001) and New York Heart Association class (27% vs 13% in class III to IV, p <0.0001) with higher incident rate of adverse events at follow-up (4.45 [3.43 to 5.69] % vs 1.29[0.94 to 1.75] % per person-year, p <0.001). TD were independently associated with higher risk of death (hazard ratio [HR] 4.1, pâ¯=â¯0.009), arrhythmic events (HR 3.8, p <0.0001), and hospitalization for HF (HR 8.02, p <0.0001). There was a fourfold increased risk of primary end point in the TD group even after propensity score matching for clinical variables including age, gender, disease complexity, physiological stage, previous palliative surgery, ventricular function, pulmonary arterial hypertension, cyanosis, and presence of systemic right ventricle (HR 4.47, p <0.0001). In conclusion, TD are predictive of adverse outcome in the ACHD population. Routine screening of thyroid function during follow-up in this population may be helpful to identify those with higher risk of death, arrhythmias, and HF.

Percutaneous patent foramen ovale (PFO) closure by traditional, double disc occluder devices was shown to be safe for patients with PFO, and more effective than prolonged medical therapy in preventing recurrent thromboembolic events. The novel suture-mediated "deviceless" PFO closure system overcomes most of the risks and limitations associated with the traditional PFO occluders, appearing to be feasible in most interatrial septum anatomies, even if data about its long-term effectiveness and safety are still lacking. The aim of the present review was to provide to the reader the state of the art about the traditional and newer techniques of PFO closure, focusing both on the procedural aspects and on the pivotal role of transesophageal echocardiography (TEE) in patient's selection, peri-procedural guidance, and post-interventional follow-up.
RESUMEN
AIMS: To evaluate if obesity has an additional negative impact on left ventricular (LV) geometry and function in normotensive pediatric patients >12 months after successful treatment of aortic coarctation (CoA). METHODS AND RESULTS: We studied 40 CoA patients (mean age 14 ± 3 years, and male sex 70%), of them 10 were obese and 30 lean. Both groups were age and sex comparable. The entire studied sample underwent 24-ambulatory blood pressure (BP) monitoring, standard echocardiographic evaluation, and speckle tracking study. Both office and 24-hour diastolic BP were significantly increased in obese patients. Obese CoA patients showed increased LV mass (52 ± 13 g/m(2.7) vs. 43 ± 9 g/m(2.7) , P = 0.02), and significant reduction in E/A compared with lean CoA patients. Myocardial deformation properties were significantly reduced in obese CoA patients in all the three studied planes (longitudinal, radial, and circumferential) compared with CoA lean patients. LV twist values showed a significant reduction in the obese CoA group (9.9° ± 2.2° vs. 14.5° ± 2.3°, P < 0.0001). CONCLUSIONS: Our study shows that obesity in successfully treated CoA children, has an additional negative effect on BP, LV mass, and cardiac function. These findings are of particular concern, since life expectancy in CoA patients is limited mainly by atherosclerosis, and all the obesity-associated abnormalities found are harbingers of higher cardiovascular risk.

We report the case of a 16-year-old boy with cardiomyopathy induced by inappropriate sinus tachycardia (IST). The patient was resistant to treatment with conventional rate-decreasing medications. Therapy with the selective sinus node I(f) current inhibitor ivabradine was started. After 3 months of ivabradine therapy, an improvement in ejection fraction and a successful decrease in heart rate were observed. No side effects occurred. We suggest that ivabradine, currently used to treat stable angina, could be considered as a second-line treatment in patients with symptomatic and refractory IST.
