RESUMO
PURPOSE: Parenting resilience is essential for the well-being and development of children with chronic illnesses. Given the importance of parenting resilience in this context, this study explored the nature of parenting resilience among mothers caring for adolescents with congenital heart disease (CHD). DESIGN AND METHODS: We adopted Husserl's phenomenological approach and conducted semistructured in-depth interviews. In addition, we conducted purposive sampling at the pediatric cardiology outpatient departments of 2 medical centers in Taiwan to recruit 11 mothers of adolescents with CHD; all of these adolescents had received open-heart surgery. Furthermore, we analyzed data by using Colaizzi's approach, and we adhered to the COnsolidated criteria for REporting Qualitative research checklist. RESULTS: Mothers caring for adolescents with CHD was a dynamic process involving problem solving. The 11 mothers in this study employed resilience to remain strong, provided a sense of normalcy for their children, and approached challenges calmly and bravely. We uncovered three major themes among these mothers: "providing support for the child, "facing challenges with equanimity," and "overcoming adversity through positivity and gratitude." CONCLUSIONS: The present results provide a deeper understanding of how mothers caring for adolescents with CHD can cultivate resilience. PRACTICE IMPLICATIONS: The study's findings can inform transitional programs for adolescents with CHD and their families, with nursing professionals supporting mothers' resilience.
RESUMO
OBJECTIVES: This study aimed to identify clinical characteristics to differentiate multisystem inflammatory syndrome in children (MIS-C) and Kawasaki disease (KD) in Taiwan, an island with a delayed cluster of MIS-C and a high incidence of KD. Additionally, we studied risk factors for developing severe complications in patients with MIS-C. METHODS: We conducted a retrospective, multicenter, cohort, and observational study that linked data on patients with MIS-C between May and December 2022 and patients with KD between 2019 and 2021 from 12 medical centers. Hemodynamic compromise, defined as the need for inotropic support or fluid challenge, was recorded in patients with MIS-C. We also evaluated maximal coronary Z-scores before treatment and one month after disease onset. RESULTS: A total of 83 patients with MIS-C and 466 patients with KD were recruited. A 1:1 age and gender-matched comparison of 68 MIS-C and KD pairs showed that MIS-C patients had a lower percentage of positive BCG red halos, lower leukocyte/platelet counts, more gastrointestinal symptoms, and a higher risk of hemodynamic compromise. In Taiwan, 38.6% of MIS-C patients experienced hemodynamic compromise, with presence of conjunctivitis and elevated levels of procalcitonin (>1.62 ng/mL) identified as independent risk factors. CONCLUSIONS: We identified two independent risk factors associated with hemodynamic compromise in MIS-C patients. The comparison between matched MIS-C and KD patients highlighted significant differences in clinical presentations, like BCG red halos, which may aid in the differential diagnosis of the two disease entities, especially in regions with a high incidence rate of KD.
RESUMO
BACKGROUND: The incidence of atrial fibrillation/atrial flutter (AF/AFL) in general population is lower in Asia compared to Western countries. It is unclear whether a similar trend exists among adults with congenital heart disease (ACHD). We determine the profile, risk factors, and impact of AF/AFL in an Asian ACHD cohort. METHODS: We included all ACHD patients diagnosed in an Asia tertiary care center between 2007 and 2018, analyzing AF (sustained and paroxysmal AF) and AFL, collectively./Purpose. RESULTS: The study encompassed 4391 patients (55.9% women), with 81% having simple, 16.3% moderate and 2.8% severe CHD. AF/AFL was observed in 6.7% of the patients, with 54.6% having paroxysmal AF, 27.3% sustained AF, and 18.1% AFL. Incidence of AF/AFL increased with age and was higher in patients with pulmonary hypertension (PH), severe CHD, and metabolic syndrome. We found a progressive trend in the onset age of arrhythmia: AFL at a younger age, followed by paroxysmal and sustained AF. Risk factors for AF/AFL included severe and moderate CHD, PH, previous interventions, and male sex (odds ratio 11.2 and 3.15, 2.03, 1.75, and 1.71, respectively). When stratifying by CHD severity, PH and male sex were significant risk factors in simple CHD, while only PH in severe CHD. Patients with AF/AFL had a significantly lower major adverse cardiovascular events-free survival rate. CONCLUSIONS: This large ACHD cohort from Asia exhibited a high incidence of AF/AFL, similar to Western reports. The risk of AF/AFL was primarily associated with hemodynamic factors such as PH and CHD severity.
RESUMO
OBJECTIVES: The evaluation of Fontan-associated liver disease is often challenging. Diffusion-weighted magnetic resonance imaging can detect hepatic fibrosis from capillary perfusion and diffusion abnormalities from extracellular matrix accumulation. This study investigated its role in the evaluation of liver disease in Fontan patients and explored possible diagnostic methods for early detection of advanced liver fibrosis. METHODS: Stable adult Fontan patients who could safely be examined with magnetic resonance imaging were enrolled, and blood biomarkers, transient elastography were also examined. RESULTS: Forty-six patients received diffusion-weighted imaging; and 58.7% were diagnosed with advanced liver fibrosis (severe liver fibrosis, 37.0%, and cirrhosis 21.7%). Two parameters of hepatic dysfunction, platelet counts (Spearman's ρ: -0.456, P = 0.001) and cholesterol levels (Spearman's ρ: -0.383, P = 0.009), decreased with increasing severity of fibrosis. Using transient elastography, a cut-off value of 14.2 kPa predicted the presence of advanced liver fibrosis, but with a low positive predictive value. When we included platelet count, cholesterol, post-Fontan years and transient elastography values as a composite, the capability of predicting advanced liver fibrosis was the most satisfactory (C statistic 0.817 ± 0.071, P < 0.001). A cut-off value of 5.0 revealed a sensitivity of 78% and a specificity of 82%. CONCLUSIONS: In Fontan patients, diffusion-weighted imaging was helpful in detecting liver fibrosis that was correlated with hepatic dysfunction. A simple score was proposed for long-term surveillance and early detection of advanced liver disease in adult Fontan patients. For adult Fontan patients with a calculated score > 5.0, we may consider timely diffusion-weight imaging and early management for liver complications.

PURPOSE: To explore the parent-child relationship through the subjective experience of adolescents with congenital heart disease (CHD). DESIGN AND METHODS: A descriptive phenomenology approach was adopted. Twelve adolescents aged from 12 to 18 years with CHD were recruited from the pediatric cardiology clinics at two medical centers in Taiwan. Data were collected through in-depth interviews. Data were analyzed using Colaizzi's phenomenological analysis method, and results were reported in accordance with the Consolidated Criteria for Reporting Qualitative Research guidelines. RESULTS: The experiences of the adolescents with CHD revealed five themes: 1. the enhancement of self-worth through parents' love; 2. the importance of parental support in desperate situations; 3. the development of a sense of security through mutual understanding; 4. growth under parental expectations; and 5. parental overcontrol disguised as love. CONCLUSIONS: The parent-child relationship encompasses both positive and negative experiences. Adolescents prioritize their relationship with parents over that with peers. PRACTICE IMPLICATIONS: Nurses caring for adolescents with CHD can improve care by recognizing the influence of parental love, support in challenges, mutual understanding, parental expectations, and potential negative consequences of overcontrol. This insight guides effective guidance for adolescents, enhancing parent-child interactions and overall well-being.

BACKGROUND: Pulsta valve is increasingly used for percutaneous pulmonary valve implantation (PPVI) in patients with a large native right ventricular outflow tract (RVOT). This study aims to elucidate the outcomes of Pulsta valve implantation within the native RVOT and assess its adaptability to various native main pulmonary artery (PA) anatomies. METHODS: A multicenter retrospective study included 182 patients with moderate to severe pulmonary regurgitation in the native RVOT who underwent PPVI with Pulsta valves® between February 2016 and August 2023 at five Korean and Taiwanese tertiary referral centers. RESULTS: Pulsta valve implantation was successful in 179 out of 182 patients (98.4%) with an average age of 26.7 ± 11.0 years. The median follow-up duration was 29 months. Baseline assessments revealed enlarged right ventricle (RV) volume (mean indexed RV end-diastolic volume: 163.1 (interquartile range, IQR: 152.0-180.3 mL/m²), which significantly decreased to 123.6(IQR: 106.6-137.5 mL/m2 after 1 year. The main PA types were classified as pyramidal (3.8%), straight (38.5%), reverse pyramidal (13.2%), convex (26.4%), and concave (18.1%) shapes. Pulsta valve placement was adapted, with distal main PA for pyramidal shapes and proximal or mid-PA for reverse pyramidal shapes. Two patients experienced Pulsta valve embolization to RV, requiring surgical removal, and one patient encountered valve migration to the distal main PA, necessitating surgical fixation. CONCLUSIONS: Customized valve insertion sites are pivotal in self-expandable PPVI considering diverse native RVOT shape. The rather soft and compact structure of the Pulsta valve has characteristics to are adaptable to diverse native RVOT geometries.

BACKGROUND: Complications arising from transcatheter closure of perimembranous ventricular septal defects (pmVSD) in children, such as residual shunts and aortic regurgitation (AR), have been observed. However, the associated risk factors remain unclear. This study identified risk factors linked with residual shunts and AR following transcatheter closure of pmVSD in children aged 2-12 years. METHODSâANDâRESULTS: The medical records of 63 children with pmVSD and a pulmonary-to-systemic blood flow ratio <2.0 who underwent transcatheter closure between 2011 and 2018 were analyzed with a minimum 3-year follow-up. The success rate of transcatheter closure was 98.4%, with no emergency surgery, permanent high-degree atrioventricular block, or mortality. Defects ≥4.5 mm had significantly higher odds of persistent residual shunt (odds ratio [OR] 6.85; P=0.03). The use of an oversize device (≥1.5 mm) showed a trend towards reducing residual shunts (OR 0.23; P=0.06). Age <4 years (OR 27.38; 95% confidence interval [CI] 2.33-321.68) and perimembranous outlet-type VSD (OR 11.94, 95% CI 1.10-129.81) were independent risk factors for AR progression after closure. CONCLUSIONS: Careful attention is crucial for pmVSDs ≥4.5 mm to prevent persistent residual shunts in transcatheter closure. Assessing AR risk, particularly in children aged <4 years, is essential while considering the benefits of pmVSD closure.

AIMS: Enhancing life satisfaction is vital for adults with congenital heart disease (ACHD). Life satisfaction potentially correlates with a health-promoting lifestyle and grit. However, the mediating role of grit-a trait marked by perseverance and long-term goal-oriented passion-between a health-promoting lifestyle and life satisfaction in ACHD remains unverified. This study aimed to examine the relationships between health-promoting lifestyle, grit, and life satisfaction in full-time employed ACHD and to confirm the mediating role of grit. METHODS AND RESULTS: A total of 181 full-time employed ACHD aged 20-59 years with patient-reported New York Heart Association class I-IV were recruited from two medical centers in northern Taiwan. Participants completed questionnaires, including the short version of the Chinese Health-Promoting Lifestyle Profile scale, Grit-10 scale, and Satisfaction with Life Scale between February and December 2022. Data analysis employed the Hayes PROCESS macro. Health-promoting lifestyle, grit, and life satisfaction were discovered to be positively correlated. Overall grit score was a partial mediator between a health-promoting lifestyle and life satisfaction, accounting for 20% of the total variation. Of the grit domains, perseverance served as a partial mediator between a health-promoting lifestyle and life satisfaction, accounting for 32% of the total variation, whereas passion had a nonsignificant mediation effect. CONCLUSION: A health-promoting lifestyle boosts ACHD individuals' life satisfaction through grit, particularly perseverance. Integrating grit into such a lifestyle could benefit from comprehending support systems and influential factors aiding grit development for enhanced life satisfaction.
RESUMO
BACKGROUND/PURPOSE: School-based cardiac screening is useful for identifying children and adolescents with a high risk of sudden cardiac death. However, because of challenges associated with cost, distance, and human resources, cardiac screening is not widely implemented, especially in rural areas with limited medical resources. This study aims to establish a cloud-based system suitable for mass cardiac screening of schoolchildren in rural areas with limited medical resources. METHODS: Students from three schools were included. They or their guardians completed a simple questionnaire, administered in paper or electronic form. Heart sounds were recorded using an electronic stethoscope. Twelve-lead electrocardiograms (ECGs) were recorded and digitalized. The signals were transmitted through Bluetooth to a tablet computer and then uploaded to a cloud server over Wi-Fi. Crowdsourced pediatric cardiologists reviewed those data from a web-based platform and provided remote consultation. In cases in which abnormal heart sounds or ECGs were noted, the students were referred to the hospital for further evaluation. RESULTS: A total of 1004 students were enrolled in this study. Of the 138 students referred, 62 were diagnosed as having an abnormal heart condition and most had previously been undiagnosed. The interrater agreeability was high. CONCLUSION: An innovative strategy combining a cloud-based cardiac screening system with remote consultation by crowdsourced experts was established. This system allows pediatric cardiologists to provide consultation and make reliable diagnoses. Combined with crowdsourcing, the system constitutes a viable approach for mass cardiac screening in children and adolescents living in rural areas with insufficient medical resources.

BACKGROUND: Most children with complex congenital heart disease (CHD) require open-heart surgery within one year of birth to survive. Thus, new mothers of infants with CHD are faced with making unexpected and difficult decisions. PURPOSE: This study was designed to explore the essence of the maternal uncertain experience prior to infants with CHD undergoing open-heart surgery. METHODS: In this study, a phenomenological approach was used and data were collected using open-ended interview guidelines structured around the Uncertainty in Illness Theory. Nine mothers of infants with CHD who had received open-heart surgery were interviewed in a hospital interview room within two weeks the operation. Colaizzi's (1978) data processing procedure was applied in the post-interview analysis. RESULTS: Five themes emerged: (1) Hit bottom and felt helpless; (2) Hit the road - An overwhelming sense of emergency; (3) The crunch - Do your best to accept destiny (4) Disease brought the unknown; (5) Hope in uncertainty. CONCLUSIONS / IMPLICATIONS FOR PRACTICE: The high-risk nature of and their unfamiliarity with the surgery made the participants experience illness uncertainty. The medical system should develop more-structured CHD information and provide emotional support in a timely manner to alleviate illness uncertainty in mothers of infants with CHD.

BACKGROUND: In recent decades, 95% of children with congenital heart disease (CHD) can survive to adolescence and adulthood. However, adolescents with CHD are prone to poorer health-related quality of life (HRQoL). It is imperative to develop a reliable and valid instrument for health professionals to monitor the HRQoL. This study aims to: (1) evaluate the psychometric properties of the traditional Chinese version of Pediatric Quality of Life™ 3.0 Cardiac Module (PedsQL-CM) and measurement invariance across adolescents with CHD and their parents; and (2) investigate the adolescent-parent agreement in HRQoL. METHODS: A total of 162 adolescents and 162 parents were recruited. Internal consistency was examined using Cronbach's alpha and McDonald's Omega. The criterion-related validity was evaluated with intercorrelations between the PedsQL-CM and PedsQL™ 4.0 Generic Core (PedsQL-GC) Scale. The construct validity was examined by second-order confirmatory factor analysis (CFA). Measurement invariance was evaluated using the multi-group CFA. The adolescent-parent agreement was analyzed with the intraclass correlation (ICC), paired t-tests, and Bland-Altman plots. RESULTS: PedsQL-CM showed acceptable internal consistency (self-reports 0.88, proxy-reports 0.91). The intercorrelations were medium to large effect size (self-reports 0.34-0.77, proxy-reports 0.46-0.68). The CFA supported the construct validity (CFI = 0.967, TLI = 0.963, RMSEA = 0.036, 90% CI = 0.026-0.046, SRMR = 0.065). The multi-group CFA proved scalar invariance between self and parent proxy-reports. Parents significantly underestimated their adolescents' HRQoL in cognitive problems (Cohen's d = 0.21) and communication (Cohen's d = 0.23) subscales, while there was a negligible difference in total HRQoL (Cohen's d = 0.16). ICCs were poor to moderate effect size with the highest and lowest agreement in heart problems and treatment subscale (ICC = 0.70) and communication subscale (ICC = 0.27), respectively. The Bland-Altman plots showed lesser variability in the heart problem and treatment subscale and the total scale. CONCLUSION: The traditional Chinese version of PedsQL-CM has acceptable psychometric properties to measure disease-specific HRQoL in adolescents with CHD. Parents may be proxies for adolescents with CHD to rate total HRQoL. When the patient-reported score is the primary outcome, the proxy-reported score could serve as a secondary outcome for research and clinical evaluation.

BACKGROUND: The optimal strategy for electroanatomic mapping-guided cryoablation of atrioventricular nodal reentry tachycardia (AVNRT) remains unclear. OBJECTIVE: The purpose of this study was to investigate the effectiveness of slow pathway late activation mapping (SPLAM) and voltage gradient mapping for AVNRT cryoablation. METHODS: From June 2020 to February 2022, all consecutive patients with AVNRT underwent SPLAM to define the wave collision point and voltage gradient mapping to define the low-voltage bridge (LVB). Conventional procedures performed from August 2018 to May 2020 served as control. RESULTS: The study and control groups comprised 36 patients (age 16.5 ± 8.2 years) and 37 patients (age 15.5 ± 7.3 years), respectively. Total procedural times were comparable, and acute success rates were 100% in both groups. Compared to controls, the number of cryomapping attempts (median 3 vs 5; P = .012) and cryoablation applications (median 1 vs 2; P <.001) were significantly lower in the study group. At median follow-up of 14.6 and 18.3 months, recurrence rates were 5.6% (2 patients) and 10.8% (4 patients) in the study and control groups (P = .402), respectively. Mapping of the Koch triangle took 11.8 ± 3.6 minutes, during which 1562 ± 581 points were collected. In SPLAM, wave collision points were defined and compatible with the final successful lesion sites in all patients, including those with multiple slow pathways. LVB could not be defined in 6 patients (16.7%), and LVB was not compatible with the final successful lesion in another 6 (16.7%). CONCLUSION: For AVNRT cryoablation, SPLAM could effectively guide the localization of slow pathway ablation sites and was particularly beneficial in patients with multiple slow pathways.

BACKGROUND: Self-expanding pulmonary valve grafts have been designed for percutaneous pulmonary valve implantation (PPVI) in patients with native repaired right ventricular (RV) outflow tracts (RVOTs). However, their efficacy, in terms of RV function and graft remodelling remain unclear. METHODS: Patients with native RVOTs who received Venus P-valve (N = 15) or Pulsta valve (N = 38) implants between 2017 and 2022 were enrolled. We collected data on patient characteristics and cardiac catheterization parameters as well as imaging and laboratory data before, immediately after, and 6 to 12 months after PPVI and identified risk factors for RV dysfunction. RESULTS: Valve implantation was successful in 98.1% of patients. The median duration of follow-up was 27.5 months. In the first 6 months after PPVI, all patients exhibited resolution of paradoxical septal motion and a significant reduction (P < 0.05) in RV volume, N-terminal pro-B-type natriuretic peptide levels, and valve eccentricity indices (-3.9%). Normalization of the RV ejection fraction (≥ 50%) was detected in only 9 patients (17.3%) and was independently associated with the RV end-diastolic volume index before PPVI (P = 0.03). Nine patients had residual or recurrent pulmonary regurgitation or paravalvular leak (graded as ≥ mild), which was associated with a larger eccentricity index (> 8%) and subsided by 12 months postimplantation. CONCLUSIONS: We identified the risk factors likely to be associated with RV dysfunction and pulmonary regurgitation following PPVI in patients with native repaired RVOTs. RV volume-based patient selection is recommended for PPVI of a self-expanding pulmonary valve, along with monitoring of graft geometry.

OBJECTIVES: To mitigate the shortage of homograft sources, the use of handmade trileaflet expanded polytetrafluoroethylene valves in pulmonary valve replacement has shown excellent results from multicentre studies conducted in Japan. However, world-wide data outside Japan are relatively insufficient. This study presents the long-term results of a single surgeon's use of flipped-back trileaflet method in a 10-year case series. METHODS: We have developed an efficient way to make a trileaflet-valved conduit utilizing flipped-back method for pulmonary valve replacement and have employed the technique since 2011. Retrospective data were studied between October 2010 and January 2020. Echocardiography, electrocardiogram, Pro-Brain Natriuretic Peptide and Magnetic Resonance Imaging data were analysed. RESULTS: Fifty-five patients were reviewed and median follow-up duration was 2.9 years. The majority of diagnoses was Tetralogy of Fallot (n = 41), and these patients subsequently underwent secondary pulmonary valve replacement at a median age of 15.6 years. Survival was 92.7% with the longest follow-up period being 10 years. There was no need for reoperation, and freedom from reintervention was 98.0% at 10 years. There were 4 deaths (3 in-hospital and 1 outpatient). One patient eventually received transcatheter pulmonary valve implantation. Postoperative echocardiography showed mild or less pulmonary stenosis and pulmonary regurgitation degree in 92.2% and 92.0% of patients, respectively. Comparable magnetic resonance imaging data (n = 25) showed significant reduction in right ventricular volumes but not in ejection fractions. CONCLUSIONS: Our series showed satisfactory long-term function of handmade flipped-back trileaflet-valved conduit used in our patients. The simple design is efficiently reproducible without complex fabrication process.

OBJECTIVES: An extended newborn critical congenital heart disease (CCHD) screening program using oximetry has been implemented in Taipei, Taiwan since April 2014. This study was conducted to investigate the test accuracy and efficiency of this screening protocol. METHODS: This study analyzed data from 30 birthing facilities representing 87.9% of live births in Taipei. Positive screening was defined as oxygen saturation <95% in either extremity or a preductal-postductal oxygen saturation difference of >3%. This study cohort was used to retrospectively estimate outcomes on the basis of different CCHD screening protocols. RESULTS: During the study period, 93 058 of 94 204 (98.8%) infants who had no prenatal suspicion were screened. The referral rate was 0.17% (156/93 058), and up to 90% of test-positive infants were referred within 48 hours of life. Forty-two CCHD cases without prenatal suspicion were detected and 97.6% were diagnosed within 72 hours of life. Of the screened newborns, 4 CCHD cases passed the screening. The false positive and false negative rates were 0.12% and 0.04%, respectively. In addition, applying our database to Spanish and updated American Academy of Pediatrics screening strategies led to more CCHD case detection. CONCLUSIONS: The Taipei protocol provided an efficient and effective screening referral system in a community setting. For optimal efficiency, we advocated the updated American Academy of Pediatrics algorithm/Spanish recommendation with a modification of immediate referral if oxygen saturation ≤90% in either extremity. The updated protocol would be practicable for nationwide screening in Taiwan and could also be applied to other regions with similar medical care systems.

BACKGROUND: Bronchiolitis is a common airway infection in young children. Hemodynamically significant congenital heart disease (CHD) predicts a more complicated course. However, the role of airway anomalies remains unknown. METHODS: We retrospectively reviewed the records of patients under 2 years old, diagnosed with CHD, and admitted between January 2011 and December 2013, before the palivizumab era. Records of bronchiolitis admissions were also extracted. Patients were grouped according to CHD condition and airway anomalies. RESULTS: A total of 230 patients with CHD were enrolled. A total of 180 (78%) and 71 (31%) patients had hemodynamically significant CHD and airway anomalies, respectively. A total of 52 (22.6%) patients were admitted for bronchiolitis 78 times. Among them, 33 (63.5%) had hemodynamically significant CHD, and 28 (53.8%) had airway anomalies. In patients with bronchiolitis admissions, the mean ventilator use, intensive care unit stay, and hospital stay were 1.08, 4.08, and 15.19 days, respectively. When compared, the mean hospital stay for bronchiolitis patients with airway anomalies was significantly longer than that of those without airway anomalies (19.8 vs. 9.9 days, p = 0.008). When further divided the patients by the presence hemodynamic significance, patients with hemodynamically significant CHD and airway anomaly had longer hospital stay than those who had neither. (21.7 vs. 8.3 days, p = 0.004) Airway anomaly was a significant risk factor for longer hospital stay in linear regression model (p = 0.007). CONCLUSIONS: Airway anomalies are common in children with CHD and are associated with longer hospital stays on bronchiolitis admission. An active survey for airway anomalies and adequate prophylaxis for bronchiolitis infection might be important in the care of children with CHD associated with airway anomalies.

The purpose of this study is to determine the ECG parameter change and the efficacy of ECG screening for cardiac adverse effect after the second dose of BNT162b2 vaccine in young population. In December 2021, in cooperation with the school vaccination system of Taipei City government, we performed a ECG screening study during the second dose of BNT162b2 vaccines. Serial comparisons of ECGs and questionnaire survey were performed before and after vaccine in four male-predominant senior high schools. Among 7934 eligible students, 4928 (62.1%) were included in the study. The male/female ratio was 4576/352. In total, 763 students (17.1%) had at least one cardiac symptom after the second vaccine dose, mostly chest pain and palpitations. The depolarization and repolarization parameters (QRS duration and QT interval) decreased significantly after the vaccine with increasing heart rate. Abnormal ECGs were obtained in 51 (1.0%) of the students, of which 1 was diagnosed with mild myocarditis and another 4 were judged to have significant arrhythmia. None of the patients needed to be admitted to hospital and all of these symptoms improved spontaneously. Using these five students as a positive outcome, the sensitivity and specificity of this screening method were 100% and 99.1%, respectively. Conclusion: Cardiac symptoms are common after the second dose of BNT162b2 vaccine, but the incidences of significant arrhythmias and myocarditis are only 0.1%. The serial ECG screening method has high sensitivity and specificity for significant cardiac adverse effect but cost effect needs further discussed. What is Known: ⢠The incidence of cardiac adverse effects was reported to be as high as 1.5 per 10 000 persons after the second dose BNT162b2 COVID-19 vaccine in the young male population based on the reporting system. What is New: ⢠Through this mass ECG screening study after the second dose of BNT162b2 vaccine we found: (1) The depolarization and repolarization parameters (QRS duration and QT interval) decreased significantly after the vaccine with increasing heart rate; (2) the incidence of post-vaccine myocarditis and significant arrhythmia are 0.02% and 0.08%; (3) The serial ECG screening method has high sensitivity and specificity for significant cardiac adverse effect.

BACKGROUND: Cardiovascular complications after Pfizer-BioNTech COVID-19 (BNT) vaccination are a concern, especially in adolescents. We analyzed the risk factors for myocarditis after BNT vaccination. METHODS: We used a special evaluation protocol for all patients aged 12-18 years who presented to our emergency department with cardiovascular symptoms after BNT vaccination. RESULTS: A total of 195 patients (109 boys and 86 girls) were enrolled. Eleven (5.6%) patients presented with arrhythmia (arrhythmia group), 14 (7.2%) had a diagnosis of pericarditis/myocarditis (the peri/myocarditis group), and the remaining 170 were controls (no cardiac involvement). Chest pain (77.6%) was the most common symptom. The median time from vaccination to symptom onset was 3 days. In the peri/myocarditis group (13 myocarditis and 1 pericarditis), the median time to the peak troponin T level was 5 days after vaccination. Abnormal electrocardiographic changes, including ST-T changes and conduction blocks, were more commonly detected in the peri/myocarditis group (85.7% vs. 12.4% in the control group, p < 0.01). Echocardiography revealed normal ventricular function in all patients. Symptoms were resolved before discharge in all, with the median duration of hospital stay being 4 days. The electrocardiography was the most appropriate screening tool for myocarditis, with a sensitivity and specificity of 85.7% and 87.6%, respectively. CONCLUSION: Pericarditis or myocarditis was diagnosed in 7.2% of adolescents presenting to the emergency department with cardiovascular symptoms after BNT vaccination. In addition to the troponin T level, ECG change listed above can be used as a screening tool for vaccine-induced cardiac complications.

BACKGROUND: Normal ECG standards in newborns, infants, children and adolescents have been collected and published by many authors. Only those by Davignon et al., Rijinbeek et al. and our two studies covered all ages from birth to adolescence. The standards reflecting the growth and development of the heart in infants, children and adolescents remained to be studied and explored. METHODS: We selected from our ECG database, after discussions and consultation, 15 key ECG parameters and analyzed for their age- and sex-specific mean, standard deviation and 2nd to 98th percentiles and their percentile charts were constructed. RESULTS: The ranges and distributions of the normal ECG standards, means and 2nd to 98th percentiles of 15 key parameters were established. CONCLUSION: A complete set of normal ECG standards of 15 key parameters from birth to adolescents is available for clinicians and researchers.
