RESUMEN
BACKGROUND: Outcome measures during acute cardiovascular disease (CVD) phases, such as quality of death, have not been thoroughly evaluated. This is the first study that compared the family members' perceptions of quality of death in deceased CVD patients and in deceased cancer patients using a bereaved family survey. METHODS: Retrospectively sent questionnaire to consecutive family members of deceased patients with CVD from ten tertiary hospitals from October 2017 to August 2018. We used the short version of the Good Death Inventory (GDI) and assessed overall care satisfaction. Referencing the GDI, the quality of death was compared between CVD patients admitted to a non-palliative care unit (non-PCU) and cancer patients in palliative care units (PCU) and non-PCUs in the Japan Hospice and Palliative Care Evaluation Study (J-HOPE Study). Additionally, in the adjusted analysis, multivariable linear regression was performed for total GDI score adjusted by the patient and participant characteristics to estimate the difference between CVD and other patients. RESULTS: Of the 243 bereaved family responses in agreement (response rate: 58.7%) for CVD patients, deceased patients comprised 133 (54.7%) men who were 80.2 ± 12.2 years old on admission. The GDI score among CVD patients (75.0 ± 15.7) was lower (worse) than that of cancer patients in the PCUs (80.2 ± 14.3), but higher than in non-PCUs (74.4 ± 15.2). After adjustment, the total GDI score for CVD patients was 7.10 points lower [95% CI: 5.22-8.97] than for cancer patients in PCUs and showed no significant differences compared with those in non-PCUs (estimates, 1.62; 95% CI [-0.46 to 5.22]). CONCLUSIONS: The quality of death perceived by bereaved family members among deceased acute CVD patients did not differ significantly from that of deceased cancer patients in general wards, however, was significantly lower than that of deceased cancer patients admitted in PCUs.

BACKGROUND: Little is known about clinical or sociodemographic factors that influence health-related quality of life (HRQoL) in patients with adult congenital heart disease (ACHD).MethodsâandâResults: We conducted a nationwide prospective cross-sectional multicenter study at 4 large ACHD centers in Japan. From November 2016 to June 2018, we enrolled 1,223 ACHD patients; 1,025 patients had an HRQoL score. Patients completed a questionnaire survey, including sociodemographic characteristics, and the 36-Item Short-Form Health Survey (SF-36). To determine factors associated with HRQoL, correlations between 2 SF-36 summary scores (i.e., physical component score [PCS] and mental component score [MCS]) and other clinical or sociodemographic variables were examined using linear regression analysis. In multivariable analysis, poorer PCS was significantly associated with 11 variables, including older age, higher New York Heart Association class, previous cerebral infarction, being unemployed, and limited participation in physical education classes and sports clubs. Poorer MCS was associated with congenital heart disease of great complexity, being part of a non-sports club, current smoking, and social drinking. Student status and a higher number of family members were positively correlated with MCS. CONCLUSIONS: This study demonstrates that HRQoL in ACHD patients is associated with various clinical and sociodemographic factors. Further studies are needed to clarify whether some of these factors could be targets for future intervention programs to improve HRQoL outcomes.

AIMS: Although shortening of the corrected QT interval (QTc) is a key finding in the diagnosis of short QT syndrome (SQTS), there may be overlap of the QTc between SQTS patients and normal subjects in childhood and adolescence. We aimed to investigate electrocardiographic findings for differentiation of SQTS patients. METHODS AND RESULTS: The SQTS group comprised 34 SQTS patients <20 years old, including 9 from our institutions and 25 from previous reports. The control group comprised 61 apparently healthy subjects with an QTc of <360 ms who were selected from 13 314 participants in a school-based screening programme. We compared electrocardiographic findings, including QT and Jpoint-Tpeak intervals (QT and J-Tpeak, respectively), those corrected by using the Bazett's and Fridericia's formulae (cB and cF, respectively) and early repolarization (ER) between the groups. QT, QTc by using Bazett's formula (QTcB), QTc by using Fridericia's formula (QTcF), J-Tpeak, J-Tpeak cB, and J-Tpeak cF were significantly shorter in the SQTS group than in the control group. On receiver operating characteristic curve analysis, the area under the curve (AUC) was largest for QTcB (0.888) among QT, QTcB, and QTcF, with a cut-off value of 316 ms (sensitivity: 79.4% and specificity: 96.7%). The AUC was largest for J-Tpeak cB (0.848) among J-Tpeak, J-Tpeak cB, and J-Tpeak cF, with a cut-off value of 181 ms (sensitivity: 80.8% and specificity: 91.8%). Early repolarization was found more frequently in the SQTS group than in the control group (67% vs. 23%, P = 0.001). CONCLUSION: A QTcB <316 ms, J-Tpeak cB < 181 ms, and the presence of ER may indicate SQTS patients in childhood and adolescence.

Left ventricular noncompaction (LVNC) is a hereditary cardiomyopathy and is associated with high morbidity and mortality. However, the role and significance of school screening for LVNC have not been fully elucidated. In this multicenter, retrospective cohort study, a total of 105 children with LVNC were included from 2000 to 2017. At the initial presentation, 44 patients (41.9%) were diagnosed by school screening. One (1.0%) patient underwent heart transplantation and four (3.8%) patients died during the study. Electrocardiogram data showed a high prevalence of fragmented QRS (33.4%) and J wave (15.7%). Treatments were needed in eight (18.2%) patients who were detected by school screening. The multivariable proportional hazards model showed T-wave abnormality on electrocardiogram in first graders was independent risk factors for major adverse cardiac events (odds ratio 4.94, p value = 0.0007). Moreover, dilation of the left atrium on chest X-ray and low ejection fraction on echocardiogram at the initial treatment were independent risk factors for treatment (odds ratio 1.7 × 107 and 22.3, p = 0.0362 and 0.0028, respectively). This study is the first report focusing on school screening in a large pediatric cohort with LVNC. With the use of abnormalities in electrocardiogram, school screening may be a good detector of and predictor for LVNC.

BACKGROUND: Working is an important concern in transitional care for adults with congenital heart disease (ACHD) because work connects people with society. Employment status is correlated with gender, but studies on patient employment by gender have rarely been conducted. This study therefore aimed to examine the employment status of ACHD by gender and to explore the factors influencing this status. METHODS: In this study, 193 Japanese ACHD (mean age: men-33.62 years, women-32.69 years; 89 men, no students included) completed a questionnaire including questions about employment status, an evaluation of hindrances to employment, the Linear Analog Scale to assess quality of life (QOL), and the Satisfaction with Life Scale (SWLS). RESULTS: In the study sample, 13 of 89 (14.6%) men and 13 of 104 (12.5%) women did not have a job. These rates were higher than the national standard rates in Japan (men: 5.0%, women: 2.9%). Of these patients, only one man and one woman listed their illness as a reason for their unemployment. The factors thought to explain unemployment were age for men and disease severity for women (P < 0.05 for both). Unemployed patients had significantly lower QOL and SWLS scores. CONCLUSIONS: Most ACHD can join the workforce but a higher percentage of ACHD do not work and find it challenging to have a career compared with the general population. Moreover, because unemployed patients have low QOL and SWLS scores, obtaining work is crucial to enable these people to have mentally and emotionally stable and fulfilling lives.

Arginine vasopressin (AVP), which induces vasoconstriction and conserves solute-free water when released during high plasma osmolality, is secreted through 2 mechanisms: osmoregulation and baroregulation. This study aims to clarify the mechanisms and influencing factors for non-osmotic AVP secretion in adult patients with congenital heart disease (CHD). AVP levels were measured in 74 adults with CHD. Non-osmotic AVP secretion was defined as excessive AVP secretion relative to the AVP level inferred from plasma osmolality. Accordingly, 10 patients (13.5%) demonstrated non-osmotic AVP secretion, with AVP levels higher than those in patients without non-osmotic AVP secretion (6.4 ± 3.1 vs. 1.6 ± 0.9 pg/ml; p < 0.0001). Non-osmotic AVP secretion was significantly correlated with diuretic use [odds ratio (OR) 7.227; confidence interval (CI) 1.743-29.962; p = 0.0006], HbA1c level (OR 11.812; CI 1.732-80.548; p = 0.012), and B-type natriuretic peptide (BNP) level (OR 1.007; CI 1.001-1.012; p = 0.022). Multiple logistic regression analysis revealed that there was a significant association between non-osmotic AVP secretion and HbA1c level (OR 9.958; 1.127-87.979; p = 0.0039), and a nearly significant relationship between non-osmotic AVP secretion and BNP (OR 1.006; CI 1.000-1.012; p = 0.056). In conclusion, this study showed that 13.5% of adult patients with CHD demonstrated non-osmotic AVP secretion, which could be correlated with heart failure and insulin resistance. The AVP system might be one of the mechanisms linking heart failure and the onset of type 2 diabetes mellitus in adults with CHD.

BACKGROUND: Fontan-associated liver disease (FALD) is an important late complication involving liver dysfunction, such as liver cirrhosis (LC) and hepatocellular carcinoma (HCC), in patients undergoing the Fontan procedure. However, the prevalence, clinical manifestation, and methods of diagnosis of FALD are still not well established.MethodsâandâResults:This study comprised 2 nationwide surveys in Japan. First, the prevalence of LC and/or HCC in patients undergoing the Fontan procedure was determined. Second, clinical manifestations in patients with LC and/or HCC were analyzed, along with data from blood tests, echocardiography, and right heart catheterization. In the 1st survey, of the 2,700 patients who underwent the Fontan procedure, 31 were diagnosed with LC and/or HCC (1.15%), and 5 died due to liver diseases (mortality: 0.19%). In the 2nd survey, data were collected from 17 patients (12 with LC, 2 with HCC, and 3 with LC+HCC. Of these 17 patients, 5 died (mortality: 29.4%). The mean age at diagnosis of LC and HCC was 23 and 31 years, respectively. Computed tomography followed by ultrasound was most frequently used for diagnosis. Blood tests revealed low platelet counts, increased hemoglobin, aspartate aminotransferase, γ-guanosine triphosphate, and total bilirubin levels, and an elevated international normalized ratio of prothrombin time. CONCLUSIONS: LC and/or HCC in patients undergoing the Fontan procedure were not rare late complications and were associated with high mortality rates.

Although some studies have attempted to find useful prognostic factors in hypertrophic cardiomyopathy (HCM), those results are not fully helpful for use in actual clinical practice. Furthermore, several genetic abnormalities associated with HCM have been identified. However, the genotype-phenotype correlation in HCM remains to be elucidated. Here, we attempted to assess patients with different types of gene mutations causing HCM and investigate the prognosis. A total of 140 patients with HCM underwent a screening test for myofilament gene mutations by direct sequencing of eight sarcomeric genes. Patients with a single mutation in cardiac troponin T, cardiac troponin I, α-tropomyosin, and regulatory and essential light chains were excluded from the study because the number of cases was too small. The clinical presentations and outcomes of the remaining 127 patients with HCM, 31 ß-myosin heavy chain (MYH7) mutation carriers, 19 cardiac myosin-binding protein C (MYBPC3) mutation carriers, and 77 mutation non-carriers were analyzed retrospectively. MYBPC3 mutation carriers had a high frequency of ventricular arrhythmia and syncope. Kaplan-Meier curves revealed no significant difference in prognosis among the three groups, but a lack of family history of sudden death (SD) and a past history of syncope were significantly related to poor prognosis. An absence of family history of SD and past history of syncope are useful prognostic factors in patients with HCM. MYH7 and MYBPC3 mutations did not significantly influence prognosis compared to non-carriers. However, patients with the MYBPC3 mutation should be closely followed for the possibility of SD.

It is well known that the reflected pressure wave in small children returns earlier than that in adolescent. The reason of early return of the reflected pressure wave in infancy is their height. The short distance between heart and reflection point makes the reflected pressure wave returning to the heart earlier. In adult, the early return (during systole) of the reflected pressure wave means disadvantage to cardiac blood supply-workload balance. The purpose of this study was to clarify whether the early return of the reflected pressure wave in small children impairs the cardiac blood supply-workload balance. This study enrolled 37 small left-to-right shunt patients with normal aortic circulation below 15 years of age. The aortic pressure waveform was recorded using a pressure sensor mounted catheter, and augmentation index and subendocardial viability ratio were calculated. The age of patients was 6.1 ± 3.2 years. The augmentation index was 8.7 ± 14.3 % and the index had a negative correlation with patients' age (r = -0.6243, p < 0.0001). The subendocardial viability ratio, which means the cardiac blood supply-workload balance, was 0.92 ± 0.14 and the index had a positive relationship with patients' age (r = 0.6435, p < 0.0001). The cardiac blood supply-workload balance gradually improves from infancy to young adulthood. One of the causes of the unfavorable cardiac blood supply-workload balance in infancy would be the accelerated aortic pressure wave reflection due to their short height.

BACKGROUND: Circumstances and outcomes of out-of-hospital cardiac arrest (OHCA) in elementary and middle school students while at school in the era of public-access defibrillation are unknown. METHODS AND RESULTS: We conducted a nationwide hospital-based survey of elementary and middle school students who had had OHCA of cardiac origin and received prehospital resuscitation in 2005-2009. Among 58 cases recruited, 90% were witnessed by bystanders; 86% had ventricular fibrillation as the initial rhythm; 74% were resuscitated by bystanders; 24% were defibrillated by bystanders; 55% occurred at school; 66% were exercise-related; 48% were followed up before the event; 67% had structural heart disease. In total, 53% of overall patients and 79% of those initially defibrillated by bystanders had a favorable neurological outcome. Patients were more likely to be defibrillated by bystanders (38% vs. 8%, P=0.012) and had a more favorable neurological outcome in schools (69% vs. 35%, P=0.017) than in other locations. The majority of arrests in schools were exercise-related (84% vs. 42%, P=0.001), occurred at sports venues, and students were resuscitated by teachers; half of the cases at school occurred in patients with a pre-event follow-up. CONCLUSIONS: After OHCA, children were more likely to be defibrillated by bystanders and had a better outcome in schools than in other locations, which may be relevant to the circumstances of events.

OBJECTIVE: Despite the broadened indications for Fontan procedure, there are patients who could not proceed to Fontan procedure because of the strict Fontan criteria during the early period. Some patients suffer from post-Glenn complications such as hypoxia, arrhythmia, or fatigue with exertion long after the Glenn procedure. We explored the possibility of Fontan completion for those patients. METHODS: Between 2004 and 2010, five consecutive patients aged between 13 and 31 years (median 21) underwent Fontan completion. These patients had been followed up for more than 10 years (10 to 13, median 11) after Glenn procedure as non-Fontan candidates. We summarise these patients retrospectively in terms of their pre-operative physiological condition, surgical strategy, and problems that these patients hold. RESULTS: Pre-operative catheterisation showed pulmonary vascular resistance ranging from 0.9 to 3.7 (median 2.2), pulmonary to systemic flow ratio of 0.3 to 1.6 (median 0.9), and two patients had significant aortopulmonary collaterals. Extracardiac total cavopulmonary connections were performed in three patients, lateral tunnel total cavopulmonary connection in one patient, and intracardiac total cavopulmonary connection in one patient, without a surgical fenestration. Concomitant surgeries were required including valve surgeries--atrioventricular valve plasty in three patients and tricuspid valve replacement in one patient; systemic outflow tract obstruction release--Damus-Kaye-Stansel procedure in two patients and subaortic stenosis resection in one patient; and anti-arrhythmic therapies--maze procedure in two patients, cryoablation in two patients, and pacemaker implantation in two patients. All patients are now in New York Heart Association category I. CONCLUSION: Patients often suffer from post-Glenn complications. Of those, if they are re-examined carefully, some may have a chance to undergo Fontan completion and benefit from it. Multiple lesions such as atrioventricular valve regurgitation, systemic outflow obstruction, or arrhythmia should be surgically repaired concomitantly.

Angiotensin-converting enzyme inhibitors (ACEI's) are an important medication in the treatment of congestive heart failure. However, ACEIs may cause harmful side effects, such as the syndrome of inappropriate secretion of antidiuretic hormone (SIADH), which is a rare but important side effect. We describe here a case of SIADH associated with ACEI administration in a 6-year-old boy with restrictive cardiomyopathy. After recovery from acute exacerbation of congestive heart failure by tolvaptan administration, an ACEI (cilazapril) was started to decrease the production of angiotensin II, which upregulates serum antidiuretic hormone secretion. The patient's heart failure symptoms worsened, including accumulation of right pleural effusion and ascites, after the initiation of ACEI administration. Cessation of ACEI administration dramatically improved his symptoms. Because it is difficult to distinguish SIADH associated with ACEI from worsening congestive heart failure, the possibility of fluid retention due to ACEI administration should always be considered when this agent is administered to patients with heart failure.

Many studies have reported that adults with congenital heart disease suffer from hypertension and cardiovascular disease even at younger ages. Therefore, we analyzed early vascular aging, which is defined as pulse wave velocity values higher than the 95th percentile for age and sex, and clarified the relationship between early vascular aging and many parameters related to cardiovascular disorders in adults with congenital heart disease. We enrolled 72 adult patients with congenital heart disease and measured their brachial-ankle pulse wave velocity. Comparing the data between age- and sex-matched controls, patients with a pulse wave velocity higher than the 95th percentile for age and sex were defined as exhibiting early vascular aging. The parameters of patients with and without early vascular aging were compared. Early vascular aging was observed in 15.6% of the patients. Age, systolic blood pressure, diastolic blood pressure, pulse pressure, blood sugar, hemoglobin A1c, uric acid, low-density lipoprotein cholesterol, and triglyceride levels were positive determinants of early vascular aging. Logistic regression analysis proved that systolic blood pressure was a significant determinant of early vascular aging (odds ratio, 1.128, 95% confidence interval, 1.049-1.214; p = 0.001). The prevalence of early vascular aging is high in adult patients with congenital heart disease. Because early vascular aging can damage a patient's vulnerable heart, careful follow-up of blood pressure and pulse wave velocity is essential.

BACKGROUND: T-wave inversion (TWI) is not considered useful for diagnosing pediatric arrhythmogenic right ventricular cardiomyopathy (ARVC), because right precordial TWI in ARVC resembles a normal juvenile pattern. OBJECTIVES: The aims of this study were to clarify the electrocardiographic (ECG) characteristics of pediatric ARVC to distinguish those patients from healthy children. METHODS: Between 1979 and 2017, 11 ARVC patients under 18 years old were registered and compared with school screening ECGs from 48,401 healthy children. RESULTS: The mean age at the first arrhythmic event or diagnosis was 13.3 ± 4.7 years. Nine patients were asymptomatic initially and were found by ECG screening, but 6 developed severe symptoms during the follow-up. Healthy children had a normal juvenile pattern, while ARVC children, especially symptomatic patients, had a significant tendency to have inferior and anterior TWI. The phenomenon of T-wave discontinuity (TWD) in which the TWI became deeper from V1 to V3 and suddenly turned positive in V5 was significantly more frequent in ARVC (60%) than healthy children (0.55%). Anterior TWI and TWD were also significantly more frequent in those who developed severe symptoms. The sensitivity and specificity of TWD were 60% (95% CI, 31-83%), and 99% (95% CI, 99-99%) to distinguish ARVC from healthy children, as well as 100% (95% CI, 71-100%) and 80% (95% CI, 51-80%), respectively, to predict severe symptoms in the future. CONCLUSIONS: The ECG is useful to distinguish ARVC children, even in the early phase. Anterior TWI and TWD could detect ARVC children and to predict the possible serious conditions.

BACKGROUND: Many adult patients with Fontan circulation are treated with antithrombotic agents, including direct oral anticoagulants (DOACs). However, few studies have investigated the efficacy, feasibility, and safety of DOACs in adult patients with Fontan circulation. METHODS AND RESULTS: In this retrospective cohort study, clinical records of 139 adult patients with Fontan circulation (70 females, 50.4%) from April 2015 to March 2018 were reviewed and classified into five groups according to the therapeutic agents used: DOAC (n = 36), vitamin K antagonist (VKA; n = 41), antiplatelet drug (n = 43), combination of an antiplatelet and anticoagulant (n = 14), and no-antithrombotic prophylaxis (n = 5). In a 1114-patient-year follow-up, 28 major events occurred, including 10 thrombotic and 18 bleeding events; 11 of 18 (61%) female patients had severe menorrhagia. The incidence (% patient-years) of major events was 0.6, 1.42, 3.74, and 5.13 in the DOAC, antiplatelet, VKA, combination, and no-antithrombotic groups, respectively. The Cox proportional hazards analysis revealed that the DOAC group had a lower rate of primary endpoints than the VKA group in males. CONCLUSIONS: DOAC may be a safe antithrombotic agent for use in adult patients with Fontan circulation, particularly in males. However, these findings should be confirmed in multi-institutional prospective studies.

The number of the adult patients with congenital heart diseases (ACHD) continues to grow owing to improvement of surgical results and medical management. Corrective surgery for complex CHD does not always mean complete cure. It is not rare that the patients will visit the cardiology institutes because of secondary lesions due to residua or sequela in adults. Some patients with CHD remain unrepairable with different degree of heart failure and pulmonary arterial hypertension. Association of arrhythmias is common in ACHD patients and sometimes critical. We experienced 265 surgical procedures for ACHD patients at our center between 1999 and 2015. Of these procedures, palliative surgery was performed in 3%, palliation to corrective surgery in 6%, primary repair in 57%, and redo surgery in 34%. Hospital mortality within 30 days in this period was 1.1%. Surgery for ACHD patients is safe, beneficial and low-risk treatment; however, tailored procedures for the individual patient are essential to obtain the optimal quality. A comprehensive multidisciplinary approach is required to fulfill this goal.

BACKGROUND: Atrial tachyarrhythmias are a major morbidity in patients with adult congenital heart disease (ACHD). However, few studies have investigated risk stratification of thromboembolic events in ACHD patients with atrial tachyarrhythmias. METHODS AND RESULTS: This retrospective cohort study reviewed the clinical records of 2314 ACHD patients from 1977 to 2014. We found 242 (10.4%) patients with atrial tachyarrhythmias and excluded 84 patients already being treated with anticoagulant therapy. The remaining 158 patients without anticoagulant therapy were retrospectively followed up from the onset of atrial tachyarrhythmia to the incidence of thromboembolic events. Fourteen thromboembolic events and 5 hemorrhagic events occurred. All patients with thromboembolic events had atrial fibrillation (AF). Thromboembolic events occurred even in the patients with low or intermediate risk as indicated by CHADS2 or CHA2DS2-VASc score. Event rates were higher than those in data from the general adult population in previous studies. Univariate analysis revealed that age≥60years (OR 4.54, 95% CI 1.47-14.06, P=0.009), vascular disease (OR 7.83, 95% CI 1.19-51.53, P=0.032), and persistent AF (OR 5.60, 95% CI 1.73-18.11, P=0.004) were the independent risk factors of thromboembolic events. CONCLUSIONS: ACHD patients with atrial tachyarrhythmias and even those with low or intermediate risk as indicated by the CHADS2 or CHA2DS2-VASc score had a higher risk of thromboembolic events. Therefore, anticoagulation should be considered earlier than in the general population in patients with risk factors of age≥60years, vascular disease, or persistent AF.

BACKGROUND: Arrhythmia and late cardiac deaths are thought to be major complications in patients after right ventricle (RV) to pulmonary artery (PA) conduit repair, although the incidence and predictors of these complications remain unknown. The aim of this study was to clarify the incidence and risk factors for arrhythmia and late deaths in patients with the RV to PA conduit repair through a Japanese multicenter study. METHODS: Three hundred fifty-one hospital survivors who underwent the RV to PA conduit repair before 1995 were studied. RESULTS: Survival rate after repair was 92% at 10 years, 88% at 20 and 25 years, respectively. Late death was observed in 30 (8.5%) including 4 patients with sudden death (SD). Higher right ventricular pressure (p = 0.02), larger cardio-thoracic ratio after repair (p = 0.02) and higher incidence of brady- or tachy-arrhythmia and SD (9/30) were associated with late death. Six (1.7%) patients developed ventricular tachycardia or ventricular fibrillation (VT/Vf). There were 22 patients who had 23 new-onset supraventricular tachy-arrhythmia (SVT). Right ventricular hypertension (p = 0.04) was associated with VT/Vf or SD. Male sex (p < 0.01), absence of previously aorto-pulmonary shunt (p < 0.05), older age at repair (p < 0.01) or longer length of follow-up (p < 0.01) were associated with SVT. CONCLUSION: Arrhythmia and late sudden death are relatively common late after the RV to PA conduit repair. Our data support recent surgical strategies of earlier primary operation and timely reoperation for progressive right ventricular outflow stenosis that may reduce the incidence of late arrhythmias and SD.
