Michielon G, DiSalvo G, Fraisse A, et al., 2020, In-hospital interstage improves interstage survival after the Norwood stage 1 operation., Eur J Cardiothorac Surg, Vol: 57, Pages: 1113-1121
OBJECTIVES: The interstage mortality rate after a Norwood stage 1 operation remains 12-20% in current series. In-hospital interstage facilitates escalation of care, possibly improving outcome. METHODS: A retrospective study was designed for hypoplastic left heart syndrome (HLHS) and HLHS variants, offering an in-hospital stay after the Norwood operation until the completion of stage 2. Daily and weekly examinations were conducted systematically, including two-dimensional and speckle-tracking echocardiography. Primary end points included aggregate survival until the completion of stage 2 and interstage freedom from escalation of care. Moreover, we calculated the sensitivity and specificity of speckle-tracking echocardiographic myocardial deformation in predicting death/transplant after the Norwood procedure. RESULTS: Between 2015 and 2019, 33 neonates with HLHS (24) or HLHS variants (9) underwent Norwood stage 1 (31) or hybrid palliation followed by a comprehensive stage 2 operation (2). Stage 1 Norwood-Sano was preferred in 18 (54.5%) neonates; the classic Norwood with Blalock-Taussig shunt was performed in 13 (39.4%) neonates. The Norwood stage 1 30-day mortality rate was 6.2%. The in-hospital interstage strategy was implemented after Norwood stage 1 with a 3.4% interstage mortality rate. The aggregate Norwood stage 1 and interstage Kaplan-Meier survival rate was 90.6 ± 5.2%. Escalation of care was necessary for 5 (17.2%) patients at 2.5 ± 1.2 months during the interstage for compromising atrial arrhythmias (2), Sano-shunt stenosis (1) and pneumonia requiring a high-frequency oscillator (2); there were no deaths. A bidirectional Glenn (25) or a comprehensive-Norwood stage 2 (2) was completed in 27 patients at 4.7 ± 1.2 months with a 92.6% survival rate. The overall Kaplan-Meier survival rate is 80.9 ± 7.0% at 4.3 years (mean 25.3 ± 15.7&thin

Chivers SC, Pavy C, Vaja R, et al., 2019, The Ozaki procedure with cardioCel patch for children and young adults with aortic valve disease: preliminary experience - a word of caution, World Journal for Pediatric and Congenital Heart Surgery, Vol: 10, Pages: 724-730, ISSN: 2150-1351
Background:The Ozaki procedure is a surgical technique for patients with significant aortic stenosis or regurgitation or both where valve repair cannot be performed. Individual cusps are cut from glutaraldehyde-treated autologous pericardium or bovine pericardium and implanted into the aortic valve position. Encouraging results have been reported within the adult population. There are limited published data on success of this procedure in younger patients.Methods:We present a series of five children and young adults who underwent the Ozaki procedure with neoaortic valve cusps made from CardioCel, a decellularized bovine pericardial patch treated with a monomeric glutaraldehyde.Results:There were no complications in the initial postoperative period and short inpatient stay. At a mean follow-up of 29.6 months (range: 22-36 months), 4 patients had no evidence of stenosis and 3 patients had trivial or no regurgitation from the neoaortic valve. Overall, two patients had complications related to the valve and underwent reintervention during the follow-up period with a Ross procedure. One of these patients who was not taking long-term anticoagulation experienced a transient ischemic attack.Conclusions:Our experience demonstrates that the Ozaki procedure with CardioCel in pediatric and young adult patients should be approached with caution. Further research with larger groups of pediatric patients, comparison of different graft materials, and longer follow-up is required to ascertain long-term success in children.

Eichhorn C, Voges I, Daubeney PEF, 2019, Out-of-hospital cardiac arrest and survival in a patient with Noonan syndrome and multiple lentigines: a case report, Journal of Medical Case Reports, Vol: 13, ISSN: 1752-1947
BACKGROUND: A 9-year-old Arabic boy attending middle school presented with an out-of-hospital cardiac arrest due to ventricular fibrillation recorded by Holter electrocardiographic monitoring. He had a background history of Noonan syndrome with multiple lentigines (also known as LEOPARD syndrome), a rare condition of autosomal dominant inheritance with approximately 200 cases reported worldwide. CASE PRESENTATION: Apart from characteristic features, the boy was known to have asymmetric septal hypertrophy with a maximum wall thickness of 24 mm measured by cardiovascular magnetic resonance imaging. A day prior to the event, he attended cardiology follow-up at our institution, and Holter monitoring was commenced. Following cardiopulmonary resuscitation by bystanders and paramedics, he reverted back into sinus rhythm after a total downtime of 24 min. He was initially treated in the intensive care unit and underwent implantable cardioverter defibrillator implantation. He has made a full recovery and remains at the top of his class. CONCLUSION: This case demonstrates that sudden cardiac arrest in patients with secondary forms of hypertrophic cardiomyopathy is not necessarily protected by apparently favorable phenotypes and that events may be preceded by non-sustained ventricular tachycardia observed by Holter monitoring. Implantable cardioverter defibrillator implantation plays a critical role in both primary and secondary prevention in patients at high risk of out-of-hospital cardiac arrest.

Sri A, Daubeney P, Prasad S, et al., A case series on cardiac and skeletal involvement in two families with PRKAG2 mutations, Case Reports in Pediatrics, Vol: 2019, ISSN: 2090-6803
Background. PRKAG2 is a rare autosomal dominant syndrome that mainly presents with hypertrophic cardiomyopathy, ventricular preexcitation, and conduction abnormalities. This case report demonstrates that the PRKAG2 mutation presents with various phenotypes already in pediatric patients. Case Summary. We describe the clinical and investigative findings in two families with a PRKAG2 mutation from the different variants in the gene on chromosome 7q36.1, emphasising that the variability of phenotypes and that presentation in childhood is common. Furthermore, we highlight that skeletal myopathy and hypertrophic cardiomyopathy are significant debilitating characteristics of the PRKAG2 mutation. Conclusion. In our report of adult and pediatric patients, early presentation in childhood with hypertrophic cardiomyopathy and skeletal muscle involvement was common, demonstrating the challenges of the clinical management of PRKAG2 mutations.
Norrish G, Field E, Mcleod K, et al., 2019, Clinical presentation and survival of childhood hypertrophic cardiomyopathy: a retrospective study in United Kingdom, European Heart Journal, Vol: 40, Pages: 986-993, ISSN: 1522-9645
Aims: Understanding the spectrum of disease, symptom burden and natural history are essential for the management of children with hypertrophic cardiomyopathy (HCM). The effect of changing screening practices over time has not previously been studied. This study describes the clinical characteristics and outcomes of childhood HCM over four decades in a well-characterized United Kingdom cohort. Methods and results: Six hundred and eighty-seven patients with HCM presented at a median age of 5.2 years (range 0-16). Aetiology was: non-syndromic (n = 433, 63%), RASopathy (n = 126, 18.3%), Friedreich's ataxia (n = 59, 8.6%) or inborn errors of metabolism (IEM) (n = 64, 9%). In infants (n = 159, 23%) underlying aetiology was more commonly a RASopathy (42% vs. 11.2%, P < 0.0001) or IEM (18.9% vs. 6.4% P < 0.0001). In those with familial disease, median age of presentation was higher (11 years vs. 6 years, P < 0.0001), 141 (58%) presented <12 years. Freedom from death or transplantation was 90.6% (87.9-92.7%) at 5 years (1.5 per 100 patient years) with no era effect. Mortality was most frequently sudden cardiac death (SCD) (n = 20, 2.9%). Children diagnosed during infancy or with an IEM had a worse prognosis (5-year survival 80.5% or 66.4%). Arrhythmic events occurred at a rate of 1.2 per 100 patient years and were more likely in non-syndromic patients (n = 51, 88%). Conclusion: This national study describes a heterogeneous disease whose outcomes depend on the age of presentation and aetiology. Overall mortality and SCD rates have not changed over time, but they remain higher than in adults with HCM, with events occurring in syndromic and non-syndromic patients.

Naqvi N, Doughty VL, Starling L, et al., 2018, Hypoxic challenge testing (Fitness to Fly) in children with complex congenital heart disease, Heart, Vol: 104, Pages: 1333-1338, ISSN: 1355-6037
OBJECTIVE: Commercial airplanes fly with an equivalent cabin fraction of inspired oxygen of 0.15, leading to reduced oxygen saturation (SpO2) in passengers. How this affects children with complex congenital heart disease (CHD) is unknown. We conducted Hypoxic Challenge Testing (HCT) to assess need for inflight supplemental oxygen. METHODS: Children aged <16 years had a standard HCT. They were grouped as (A) normal versus abnormal baseline SpO2(≥95% vs <95%) and (B) absence versus presence of an actual/potential right-to-left (R-L) shunt. We measured SpO2, heart rate, QT interval corrected for heart rate and partial pressure of carbon dioxide measured transcutaneously (PtcCO2). A test failed when children with (1) normal baseline SpO2desaturated to 85%, (2) baseline SpO285%-94% desaturated by 15% of baseline; and (3) baseline SpO275%-84% desaturated to 70%. RESULTS: There were 68 children, mean age 3.3 years (range 10 weeks-14.5 years). Children with normal (n=36) baseline SpO2desaturated from median 99% to 91%, P<0.0001, and 3/36 (8%) failed the test. Those with abnormal baseline SpO2(n=32) desaturated from median 84% to 76%, P<0.0001, and 5/32 (16%) failed (no significant difference between groups). Children with no R-L shunt (n=25) desaturated from median 99% to 93%, P<0.0001, but 0/25 failed. Those with an actual/potential R-L shunt (n=43) desaturated from median 87% to 78%, P<0.0001, and 8/43 (19%) failed (difference between groups P<0.02). PtcCO2, heart rate and QT interval corrected for heart rate were unaffected by the hypoxic state. CONCLUSIONS: This is the first evidence to help guide which children with CHD need a preflight HCT. We suggest all children with an actual or potential R-L shunt should be tested.
Shi WY, Moreno-Betancur M, Nugent AW, et al., 2018, Long-term outcomes of childhood left ventricular non-compaction cardiomyopathy: results from a national population-based study, Circulation, Vol: 138, Pages: 138-367, ISSN: 0009-7322
Background -Long-term outcomes for childhood left ventricular non-compaction (LVNC) are uncertain. We examined late outcomes for children with LVNC enrolled in a national population-based study. Methods -The National Australian Childhood Cardiomyopathy Study includes all children in Australia with primary cardiomyopathy diagnosed <10 years of age between 1987 and 1996. Outcomes for LVNC subjects with a dilated phenotype (LVNC-D) were compared to those with dilated cardiomyopathy (DCM). Propensity-score analysis was used for risk factor adjustment. Results -There were 29 subjects with LVNC (9.2% of all cardiomyopathy subjects) with a mean annual incidence of newly diagnosed cases of 0.11 per 100,000 at-risk persons. Congestive heart failure was the initial symptom in 24 (83%) of 29 subjects, and 27 (93%) had a dilated phenotype (LVNC-D). The median age at diagnosis was 0.3 (interquartile interval 0.08 - 1.3) years of age. The median (interquartile interval) duration of follow-up was 6.8 (0.7-14.1) years for all subjects and 24.7 (23.3 - 27.7) years for surviving subjects. Freedom from death or transplantation was 48% (95% CI 30 - 65%) at 10 years after diagnosis and 45% (95% CI 27-63%) at 15 years. By competing risk analysis, 21% of LVNC subjects were alive with normal LV systolic function and 31% were alive with abnormal function at 15 years. Propensity-score matching between LVNC-D and DCM subjects suggested a lower freedom from death/transplantation at 15 years after diagnosis in the LVNC-D subjects (LVNC-D: 46% (95% CI 26-66%) vs. DCM: 70% (95% CI 42-97%), p=0.08). Using propensity-score inverse probability of treatment weighted Cox regression, we found evidence that LVNC-D was associated with a greater risk of death or transplantation (HR 2.3, 95% CI 1.4-3.8, p=0.0012). Conclusions -Symptomatic children with LVNC usu

Background -Late survival and symptomatic status of children with hypertrophic cardiomyopathy (HCM) have not been well defined. We examined long-term outcomes for pediatric HCM. Methods -The National Australian Childhood Cardiomyopathy Study is a longitudinal population-based cohort study of children (0-10 years) diagnosed with cardiomyopathy between 1987 and 1996. The primary study end-point was time to death or cardiac transplantation. Results -There were 80 patients with HCM with median age at diagnosis of 0.48 (Inter-quartile range [IQR] 0.1, 2.5) years. Freedom from death/transplantation (95% confidence interval [CI]) was 86 (77-92)% one year after presentation, 80 (69-87)% at 10 years and 78 (67-86)% at 20 years. From multivariable analyses, risk factors for death/transplantation included symmetric left ventricular hypertrophy at the time of diagnosis (hazard ratio [HR] 4.20 95%CI 1.60, 11.05 p=0.004), Noonan syndrome (HR 2.88, 95%CI 1.02, 8.08, p=0.045), higher posterior wall thickness z-score (HR 1.45, 95%CI 1.22, 1.73, p<0.001) and lower fractional shortening z-score (HR 0.84, 95%CI 0.74, 0.95, p=0.005) during follow-up. Nineteen (23%) subjects underwent left ventricular myectomy. At median 15.7 years' follow-up, 27 (42%) of 63 survivors were treated with beta-blocker and 13 (21%) had an implantable cardioverter-defibrillator. Conclusions -The highest risk of death or transplantation for children with HCM is within one year post-diagnosis, with low attrition rates thereafter. Many subjects receive medical, surgical or device therapy.

Background Improved understanding of dilated cardiomyopathy (DCM) due to titin truncation (TTNtv) may help guide patient stratification.Objectives The purpose of this study was to establish relationships among TTNtv genotype, cardiac phenotype, and outcomes in DCM.Methods In this prospective, observational cohort study, DCM patients underwent clinical evaluation, late gadolinium enhancement cardiovascular magnetic resonance, TTN sequencing, and adjudicated follow-up blinded to genotype for the primary composite endpoint of cardiovascular death, and major arrhythmic and major heart failure events.Results Of 716 subjects recruited (mean age 53.5 ± 14.3 years; 469 men [65.5%]; 577 [80.6%] New York Heart Association function class I/II), 83 (11.6%) had TTNtv. Patients with TTNtv were younger at enrollment (49.0 years vs. 54.1 years; p = 0.002) and had lower indexed left ventricular mass (5.1 g/m2 reduction; padjusted = 0.03) compared with patients without TTNtv. There was no difference in biventricular ejection fraction between TTNtv+/− groups. Overall, 78 of 604 patients (12.9%) met the primary endpoint (median follow-up 3.9 years; interquartile range: 2.0 to 5.8 years), including 9 of 71 patients with TTNtv (12.7%) and 69 of 533 (12.9%) without. There was no difference in the composite primary outcome of cardiovascular death, heart failure, or arrhythmic events, for patients with or without TTNtv (hazard ratio adjusted for primary endpoint: 0.92 [95% confidence interval: 0.45 to 1.87]; p = 0.82).Conclusions In this large, prospective, genotype-phenotype study of ambulatory DCM patients, we show that prognostic factors for all-cause DCM also predict outcome in TTNtv DCM, and that TTNtv DCM does not appear to be associated with worse medium-term prognosis.
Delle Donne G, Rosés Noguer F, Till J, et al., 2017, Ivabradine in Postural Orthostatic Tachycardia Syndrome: Preliminary Experience in Children., Am J Cardiovasc Drugs
OBJECTIVE: Ivabradine is a selective and specific inhibitor of the I(f) current in the sinoatrial and atrioventricular nodes. It decreases heart rate and myocardial oxygen consumption at rest and during exercise. It is used in adults for management of heart failure and angina, but promising results have been obtained in postural orthostatic tachycardia syndrome (POTS). There is little experience of ivabradine in childhood, although it is used on a compassionate basis. Our aim was to review our experience of ivabradine in a retrospective evaluation of pediatric patients with POTS. METHODS: We evaluated all patients younger than 18 years for whom ivabradine had been prescribed for this indication, from February 2008 to June 2014. RESULTS: Twenty-two patients were identified (15 female). Median age was 14.5 years (11-17 years). The ivabradine dosage after up-titration was 0.1 mg/kg per dose twice daily. In 15 (68%) symptoms improved. Ivabradine was suspended in five, but only in one for worsening of symptoms. There was a reduction in heart rate on resting electrocardiogram (EKG) from a mean (standard deviation) of 82.5 (13.6) bpm to a mean of 71 (16.5) bpm (p = 0.007). No patient had increased duration of QTc (p = 0.44). One (4.5%) experienced phosphenes. CONCLUSIONS: From this initial experience, ivabradine is safe in patients younger than 18 years with POTS. We observed improvement of symptoms in 68% and phosphenes in less than 5%. Further studies are needed to assess the safety in a randomized control setting.
Bonnet D, Berger F, Jokinen E, et al., 2017, Ivabradine in Children With Dilated Cardiomyopathy and Symptomatic Chronic Heart Failure, Journal of the American College of Cardiology, Vol: 70, Pages: 1262-1272, ISSN: 0735-1097
BackgroundHeart rate reduction as a therapeutic target has been investigated in adults with heart failure (HF). Ivabradine has shown promising efficacy, but has not been evaluated in children. Currently, treatment recommendations for chronic pediatric HF are based mainly on chronic HF guidelines for adults.ObjectivesThe authors explored the dose-response relationship of ivabradine in children with dilated cardiomyopathy and symptomatic chronic HF. The primary endpoint was ≥20% reduction in heart rate from baseline without inducing bradycardia or symptoms.MethodsThis was a randomized, double-blind, placebo-controlled, phase II/III study with 12 months of follow-up. Children (n = 116) receiving stable HF therapy were randomized to either ivabradine or placebo. After an initial titration period, the dose was adjusted to attain the primary endpoint. Left ventricular function (echocardiography), clinical status (New York Heart Association functional class or Ross class), N-terminal pro–B-type natriuretic peptide, and quality of life (QOL) were assessed.ResultsThe primary endpoint was reached by 51 of 73 children taking ivabradine (70%) versus 5 of 41 taking placebo (12%) at varying doses (odds ratio: 17.24; p < 0.0001). Between baseline and 12 months, there was a greater increase in left ventricular ejection fraction in patients taking ivabradine than placebo (13.5% vs. 6.9%; p = 0.024). New York Heart Association functional class or Ross class improved more with ivabradine at 12 months than placebo (38% vs. 25%; p = 0.24). There was a trend toward improvement in QOL for ivabradine versus placebo (p = 0.053). N-terminal pro–B-type natriuretic peptide levels decreased similarly in both groups. Adverse events were reported at similar frequencies for ivabradine and placebo.ConclusionsIvabradine safely reduced the resting heart rate of children with chronic HF and dilated cardiomyopathy. Ivabradine’s effect on heart rate was variable, highlighting the
