After 1026 person-years follow-up, the 5-year survival rate was 52.0% and 65.7% in heterotaxy syndrome and other patients with complex CHD, respectively (P = .239; Figure, A).The cause of mortality is listed in Table III.Operation-related mortality was the major cause in our cohort, accounting for 70% (n = 70) of deaths and, of them, infection during the perioperative stage accounted for 35.7% . Congenit Heart Dis. Furthermore, despite significant improvement in neonatal survival over time and substantial increase in rates of fetal diagnosis, overall outcomes have not improved appreciably in the more recent birth eras, except as compared with the earliest era (1985 to 1991). In this latter group, a multivariable Cox regression model was also constructed to assess the association between surgical pathway (univentricular versus biventricular repair) and mortality after adjusting for baseline confounders.

Perinatal and infant outcomes of prenatal diagnosis of heterotaxy syndrome (asplenia and polysplenia). Discover Pediatric Collections on COVID-19 and Racism and Its Effects on Pediatric Health. In conclusion, we found a higher survival rate (63%) than previously published in patients with heterotaxy syndrome and AV block or bradycardia diagnosed prenatally. HS has long been known to be a challenging disease with suboptimal short- and midterm outcomes.4–6,12 Although some recent reports have suggested improved outcomes over time,7–9,13,14 other studies have not found improved survival in the current era.15,16 These discrepancies among reported outcomes in HS may, at least in part, be due to small sample sizes and short follow-up times in previous series. Predictors of poor outcome among children with heterotaxy syndrome: a retrospective review. However, the interstage mortality for patients with heterotaxy syndrome was much higher than the non-heterotaxy group (P = 0.001) (Table 1) and the cumulative survival rate except for postoperative death was significantly lower for heterotaxy syndrome with a functional single ventricle (P = 0.001, OR = 5.4, 95% CI: 2.06-14.50) (Figure 2). A total of 264 patients (49% female) met inclusion criteria, 118 (44.7%) with asplenia and 146 (55.3%) with polysplenia phenotypes. Found inside – Page 16Preoperative diagnoses included heterotaxy syndrome in 55, asplenia in 48, preoperative pulmonary venous obstruction in 35, and pulmonary atresia in 20. POTENTIAL CONFLICT OF INTEREST: The authors have indicated they have no potential conflicts of interest to disclose. for left-right laterality and heterotaxy syndrome, including ZIC3, NODAL, LEFTY2.11,12 In the clinical field, precise diagnosis and surgical treatment of patients with heterotaxy syndrome have recently advanced as well. By including a larger cohort of patients with HS, both prenatally and postnatally diagnosed, the data presented in this study provide a more complete picture of risk among infants born with this challenging diagnosis and should inform prenatal counseling and postnatal risk stratification. There were eight neonatal deaths and four infant deaths. Found inside – Page 314Heterotaxy syndrome is characterised by a different (Greek: heteros) ...

A Severe cardiac complication associated with Heterotaxy Syndrome is a major cause of short life span of the affected children. We thank Minmin Lu, MS, for her statistical programming related to this project.

Heterotaxy (Htx) syndrome is a serious congenital malfor-mation with high mortality and morbidity characterized by the failure to establish normal left-right (LR) body asymmetry. Congenital atrioventricular (AV) block is commonly associated with heterotaxy syndrome; together they have reportedly low survival rates (10-25%). Medical advancement including surgical intervention assists in increasing the life .

Bookshelf Heterotaxy syndrome is a congenital rare defect that can affect many organs, including heart, liver and other organs. However, many studies have now documented an increased survival in patients with heterotaxy in more recent years. Objective: The purpose of this study was to investigate the associations between arrhythmias, anatomy, and outcomes in a large HS cohort.

Of the 154 fetuses with heterotaxy syndrome, 91 had polysplenia syndrome, 22/91(24%) with bradycardia or AV-block. Results: Methods: This suggests that in patients with borderline anatomy, pursuing a biventricular reconstruction strategy may provide a survival benefit despite the complexities of the repair. Multivariable Cox Regression Model of Factors Associated With Death. Within this group, after adjusting for baseline confounders that differed between the univentricular and biventricular repair groups, univentricular repair remained an independent predictor of shorter time to death. You will be redirected to aap.org to login or to create your account. Analyses were performed for the entire cohort of patients and separately for the patients who underwent at least one surgical intervention to determine if the latter group had a different set of risk factors compared with the entire cohort. There are different forms of heterotaxy syndrome. Found inside – Page 240Cohen MS, Schultz AH, Tian ZY, et al: Heterotaxy syndrome with functional single ventricle: does prenatal diagnosis improve survival? Ann Thorac Surg 2006; ... As shown in Fig 2, overall mortality was similar across birth eras (P = .116). The primary outcome was death and the secondary outcome was pacemaker placement. Furthermore, rates of prenatal termination were high, especially in the asplenia cohort, which likely resulted in a selection bias toward lower-risk patients in the live-born group. A single-center retrospective review of patients ≤21 years of age diagnosed with HS was performed. Around 1 in 10,000 babies are born with heterotaxy, but virtually no two patients are alike. The word heterotaxy is derived from the Greek: heteros-meaning other than, and taxis-meaning arrangement. Hydrops, cardiac dysfunction, prematurity and low ventricular rates were predictors of death. Heterotaxy syndrome, which occurs in 1 in every 6000 to 1 in every 20,000 live births , is a heterogeneous disorder associated with a wide spectrum of cardiac defects and extracardiac anomalies [2, 3]. The basic demographic data of the 42 patients with heterotaxy and 54 patients with CCHD are listed in Table 1.In the heterotaxy group, 38 had right atrial isomerism and 4 had left atrial isomerism. Thirteen (59%) patients had sinus bradycardia at diagnosis, 8 (36%) complete AV block, and 1 (5%) second-degree AV-block. Life expectancy & Survival Rate. 2008 Jul;21(7):469-76. doi: 10.1080/14767050802052786. Heterotaxy syndrome (HS) is a rare disorder with complex anatomy involving misarrangements of the cardiac conduction system. Median follow-up time among survivors was 10.2 years (IQR: 4.2–18), with the longest follow-up of 31.5 years.

In univariate analysis, several anatomic, surgical, and functional variables were associated with a higher mortality risk in the cohort (Supplemental Table 6). 2016 Apr;47(4):443-9. doi: 10.1002/uog.14871.
