Abstract
Background Our cardiac center established a systematic approach for inpatient cardiovascular genetics evaluations of infants with congenital heart disease, including routine chromosomal microarray (CMA) testing. This provides a new opportunity to investigate correlation between genetic abnormalities and postoperative course. Methods and Results Infants who underwent congenital heart disease surgery as neonates (aged ≤28 days) from 2015 to 2020 were identified. Cases with trisomy 21 or 18 were excluded. Diagnostic genetic results or CMA with variant of uncertain significance were considered abnormal. We compared postoperative outcomes following initial congenital heart disease surgery in patients found to have genetic abnormality to those who had negative CMA. Among 355 eligible patients, genetics consultations or CMA were completed in 88%. A genetic abnormality was identified in 73 patients (21%), whereas 221 had negative CMA results. Genetic abnormality was associated with prematurity, extracardiac anomaly, and lower weight at surgery. Operative mortality rate was 9.6% in patients with a genetic abnormality versus 4.1% in patients without an identified genetic abnormality (P=0.080). Mortality was similar when genetic evaluations were diagnostic (9.3%) or identified a variant of uncertain significance on CMA (10.0%). Among 14 patients with 22q11.2 deletion, the 2 mortality cases had additional CMA findings. In patients without extracardiac anomaly, genetic abnormality was independently associated with increased mortality (P=0.019). CMA abnormality was not associated with postoperative length of hospitalization, extracorporeal membrane oxygenation, or >7 days to initial extubation. Conclusions Routine genetic evaluations and CMA may help to stratify mortality risk in severe congenital heart disease with syndromic or nonsyndromic presentations.

Abstract
Down Syndrome (Ds) is the most common chromosomal cause of intellectual disability that results from triplication of chromosome 21 genes. Individuals with Ds demonstrate cognitive deficits in addition to comorbidities including cardiac defects, pulmonary arterial hypertension (PAH), low blood pressure (BP), and differences in autonomic regulation. Many individuals with Ds are born with heart malformations and some can be surgically corrected. Lower BP at rest and in response to exercise and other stressors are a prevalent feature in Ds. These reduced cardiovascular responses may be due to underlying autonomic dysfunction and have been implicated in lower exercise/work capacity in Ds, which is an important correlate of morbidity, mortality and quality of life. Exercise therapy can be beneficial to normalize autonomic function and may help prevent the development of co-morbidities in Ds. We will review cardiovascular physiology and pathophysiology in individuals with Ds, along with exercise therapy and special considerations for these individuals.

Abstract
AbstractDown Syndrome is a genetic disorder caused by a third copy of chromosome 21. One of the main feature of the syndrome is the facial dysmorphism, characterized by broad, flat face, oblique eyelid rhymes, skin folds at the inner corner of the eyes (epicanthus), receding chin, protrusion of the tongue. These features are often social and functional obstacles, reducible with surgical interventions. The first facial plastic/cosmetic surgery approaches on Down children were performed in 1960 in Germany, Great Britain and the United States, where plastic surgeons began to reshape the Down patients physiognomy through the surgical correction of the face, tongue, eyes, nose, of the nostrils, of the neck. Recent studies have shown that in spite of the tendency to infections and early pulmonary hypertension in children with DS, surgery is not contraindicated, as previously suggested, but can be performed with very good results. This treatment has aesthetic, functional, rehabilitative, social effects, as well as favorable outcome on the familiar behavior. However different issues emerge in cases of patients presenting intellectual disability and unable to understand the consequences or the side effects related to plastic surgery. In this aspect, different Countries have enacted distinct laws directly regulating the consensuses for such intervention, with the goal to reduce the risks for the affected patients and the respect of their willing and social inclusion.

Bradyarrhythmias in Repaired Atrioventricular Septal Defects: Single-Center Experience Based on 34 Years of Follow-Up of 522 Patients. Pediatr Cardiol 2018; 39:1590-1597. [PMID: 29948031 DOI: 10.1007/s00246-018-1934-4] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2018] [Accepted: 06/07/2018] [Indexed: 10/14/2022]
Abstract
Atrioventricular Septal Defect (AVSD) is a rare congenital heart defect (CHD) often associated with genetic syndromes, most commonly Down syndrome (DS). Over the last four decades, surgical repair has increased survival and improved quality of life in these patients. The prevalence of bradyarrhythmias namely, atrioventricular block (AVB) and sinus node dysfunction (SND) in AVSD is partially known. 522 cases with both partial and complete AVSD (38.7% with DS), undergoing intracardiac repair from 1982 to 2016 at our institution, were reviewed from our system database. 38 (7.3%) patients received permanent PM implantation for AVB (early or late) or SND. On one hand, AVB requiring PM was found in 26 (4.98%). This was further subdivided into early-onset 14 (2.6%) and late-onset AVB 12 (2.2%) (median 4 [IQR 1-7] years). On the other hand, 12 (2.3%) experienced late SND requiring PM (median 11 [IQR 3.5-15.2] years). Early and late AVB were independent from the type of AVSD (partial or complete), whereas the late SND was remarkably observed in complete AVSD compared to partial AVSD (p = 0.017). We classified the cohort into two main categories: DS (202, 38.7%) and non-DS (320, 61.3%). At Kaplan-Meier survival analysis, DS was significantly associated with late-onset bradyarrhythmias (p = 0.024). At Cox regression analysis, we identified DS as an independent predictor of PM implantation (HR 2.17). In conclusion, about 7% of repaired AVSD patients need PM implantation during follow-up. There are no differences in early and late AVB occurrence according to the type of AVSD. There is a higher incidence of late SND in repaired complete AVSD, with a later timing onset in patients with associated DS. Moreover, DS seems to be an independent predictor of PM implantation.

Abstract
OBJECTIVE To evaluate and describe resource use and perioperative morbidities among those patients with genetic conditions undergoing cardiac surgery. STUDY DESIGN Using the Pediatric Health Information System database, we identified patients ≤18 years old with cardiac surgery classified by Risk Adjustment for Congenital Heart Surgery (RACHS) during 2003-2014. A total of 95 253 patients met study criteria and included no genetic conditions (84.6%), trisomy 21 (9.9%), trisomy 13 or 18 (0.2%), 22q11 deletion (0.8%), Turner syndrome (0.4%), and "other" genetic conditions (4.2%). We compared perioperative complications and procedures in each genetic condition with patients without genetic conditions using regression analysis. RESULTS All groups with genetic conditions, excluding trisomy 21 RACHS 3-5, experienced increased length of stay and cost among survivors. Complications varied by genetic condition, with patients with trisomy 21 having increased odds of pulmonary hypertension and nosocomial infections. Patients with 22q11 only had increased odds of infection. Patients with Turner syndrome had increased odds of acute renal failure (OR 2.35). Patients with trisomy 13 or 18 had increased odds of pulmonary hypertension (OR 3.13), acute renal failure (OR 2.93), cardiac arrest (OR 2.84), and nosocomial infections (OR 3.53), and those with "other" genetic conditions had increased odds of all complications. CONCLUSIONS Children with congenital heart disease and genetic conditions, except trisomy 21 RACHS 3-5, had increased costs and length of stay. Perioperative morbidities were more common and differed across genetic condition subgroups. Patient-specific risk factors are important for risk stratification, benchmarking, and counseling with families.

Abstract
Down syndrome is the most common chromosomal abnormality among live-born infants. Through full or partial trisomy of chromosome 21, Down syndrome is associated with cognitive impairment, congenital malformations (particularly cardiovascular) and dysmorphic features. Immune disturbances in Down syndrome account for an enormous disease burden ranging from quality-of-life issues (autoimmune alopecia) to more serious health issues (autoimmune thyroiditis) and life-threatening issues (leukaemia, respiratory tract infections and pulmonary hypertension). Cardiovascular and pulmonary diseases account for ∼75% of the mortality seen in persons with Down syndrome. This review summarises the cardiovascular, respiratory and immune challenges faced by individuals with Down syndrome, and the genetic underpinnings of their pathobiology. We strongly advocate increased comparative studies of cardiopulmonary disease in persons with and without Down syndrome, as we believe these will lead to new strategies to prevent and treat diseases affecting millions of people worldwide.

Abstract
OBJECTIVE We describe patient characteristics and postoperative morbidity and mortality rates for patients with Down syndrome undergoing congenital heart disease surgery. METHODS This retrospective cohort study used the Society of Thoracic Surgeons Congenital Heart Surgery Database to compare patient characteristics and postoperative outcomes for patients (0-18 years) with or without Down syndrome who underwent surgery in 2000-2008. RESULTS A total of 45,579 patients (4350 patients with Down syndrome and 41,229 without Down syndrome) were included (median age: 7 months [interquartile range [IQR]: 47 days to 4 years]; 56% male). Patients with Down syndrome were younger at surgery, with the exception of those undergoing tetralogy of Fallot repair or atrioventricular septal defect repair. Mortality rates for patients with or without Down syndrome did not differ significantly. Lengths of stay were prolonged for patients with Down syndrome undergoing atrial septal defect closure (median: 4 days [IQR: 3-5 days] vs 3 days [IQR: 2-4 days]; P < .0001), ventricular septal defect closure (median: 5 days [IQR: 4-8 days] vs 4 days [IQR: 3-6 days]; P < .0001), or tetralogy of Fallot repair (7 days [IQR: 5-10 days] vs 6 days [IQR: 5-9 days]; P < .001) and were associated with postoperative respiratory and infectious complications. Patients with Down syndrome undergoing ventricular septal defect closure had a higher rate of heart block requiring pacemaker placement (2.9% vs 0.8%; P < .0001). CONCLUSION In this large, contemporary cohort, Down syndrome did not confer a significant mortality risk for the most common operations; however, postoperative morbidity remained common.
