Abstract
BACKGROUND AND AIM Heterotaxy syndrome, being right atrial isomerism (RAI) or left atrial isomerism (LAI), often presents with Congenital Heart Disease (CHD). Intestinal abnormalities, including malrotation are common. We assessed the spectrum of gut abnormalities and their impact on medium-term outcome in a cohort of patients with fetal and postnatal diagnoses of heterotaxy syndrome. METHODS We reviewed the cardiology records of heterotaxy syndrome patients from two centres, regarding the presence of CHD, time for cardiac intervention, presence of gastrointestinal abnormalities, and type/time of surgery. A questionnaire about gastrointestinal status was sent to patients <18 years old. Kaplan-Meier curves were derived for survival data and freedom from intervention. RESULTS Data were included for 182 patients (49 RAI and 133 LAI) of 247 identified. Questionnaires were sent to 77 families and 47 replied. CHD was present in all RAI and 61.7% of LAI cases. Thirty-eight patients had abdominal surgery (20.9%), similar for RAI and LAI (20.4% versus 21%, p> 0.99): Ladd procedure in 17 (44.7%), non-Ladd in 12 (31.5%), and both procedures in 9 (23.7%). Ten-year freedom from Ladd procedure for all was 86% for the whole cohort (RAI = 87%; LAI = 85%, p = 0.98). Freedom from any gastrointestinal surgery at 10 years was 79% for the whole cohort (RAI = 77%; LAI = 80%, p = 0.54). Ten-year freedom from cardiac surgery was 31% for the whole cohort (RAI = 6%; LAI = 43%, p < 0.0001). CONCLUSIONS In our cohort, one in five patients required abdominal surgery, mostly in their first year of life, similar for RAI and LAI. Between 1 and 10 years of follow-up, the impact of gastrointestinal abnormalities on outcome was minimal. Medium term survival was related to CHD.

Abstract
Human laterality disorders comprise a group of diseases characterized by abnormal location (situs) and orientation of thoraco-abdominal organs and vessels across the left-right axis. Situs inversus totalis is mirror image reversal of thoraco-abdominal organs/great vessels. Situs ambiguus, better known as heterotaxy, is abnormal arrangement of thoraco-abdominal organs across the left-right axis excluding situs inversus totalis. Heterotaxy, also referred to as atrial or atrial appendage isomerism, is characterized by abnormal location of left-sided or right-sided organs with loss of asymmetry of normally paired asymmetric organs. It is associated with a variety of anomalies involving the heart, great vessels, lungs and intra-abdominal organs. Right and left atrial isomerism are associated with multiple complex congenital cardiac and vascular anomalies, many of which are lethal when untreated. Isomerism may also affect the lungs, spleen, liver, gall bladder, and intestines. Innovative surgical therapy of heterotaxy/isomerism has reduced early mortality and markedly improved long-term prognosis.

Abstract
Situs anomalies are rare structural defects affecting 0.01% of general population. They present with multisystem structural defects mostly involving cardiovascular, respiratory and GI systems. Situs abnormality with presence of multiple spleen is termed as left atrial isomerism with anatomical and structural differences to its countertype situs ambiguous with asplenia (right atrial isomerism). In this case report, we present an adult case of situs ambiguous anomaly which was diagnosed incidentally during laparoscopic cholecystectomy. The patient had enlarged left lobe of liver, multiple splenules on right side, malrotated small and large gut, interrupted inferior vena cava with azygos continuation, and bilateral bilobed lungs. It is concluded that variations in situs ambiguous cases differ and a single description is not possible. It is crucial to reveal these variations by using imaging modalities and being aware of them prior to surgery and invasive intervention to prevents the possible risks and complications.

Standardized Approach to Intervention for Intestinal Malrotation in Single Ventricle Patients with Heterotaxy Syndrome: Impact on Interstage Attrition and Time to Superior Cavopulmonary Connection. Pediatr Cardiol 2019; 40:1224-1230. [PMID: 31240371 DOI: 10.1007/s00246-019-02136-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2019] [Accepted: 06/13/2019] [Indexed: 01/19/2023]
Abstract
Heterotaxy syndrome (HS) is a significant determinant of outcome in single ventricle (SV) physiology. Attrition rate and time-related events associated with intestinal malrotation (IM) are, yet, to be determined. We sought to evaluate hospital and interstage outcomes in relation with operative intervention for IM (IMO). Twelve SV/HS patients, who underwent IMO, from January 2004 to December 2016, were studied. Early shunt failure, time to superior cavopulmonary connection (SCPC) and interstage attrition were assessed. Since September 2014, based on a comprehensive standardized protocol, IMO was performed at the time of hospitalization for stage-I palliation (S1P) irrespective of clinical manifestations. Patients were assigned to Group A (n = 8): expectant /symptoms-driven versus Group B (n = 4): protocol-driven. At S1P 7 had systemic-to-pulmonary shunt (SPS), 1 SPS with anomalous pulmonary venous return (APVR) repair (Group A) compared to 2 SPS, 1 SPS with APVR repair and 1 Norwood operation (Group B). Median duration from S1P to IMO was 82 days (range 57-336; Group A) compared to 14 days (range 11-31; Group B); p < 0.05. Median age at IMO was 87 days (range 8-345) [Group A: 99 days (range 68-345) vs Group B: 25 days (range 8-39)] (p < 0.05). Early SPS failure occurred in 25% (2 of 8) for Group A compared to none in Group B (p < 0.05). Hospital mortality following IMO was 25% [Group A: 37.5% (3 of 8) vs Group B: 0; p < 0.05]. Interstage survival was 67% [Group A: 50% (4 of 8) vs Group B: 100%; p < 0.05]. Time to SCPC following S1P was 186 days (range 169-218) for Group A compared to 118 days (range 97-161) (Group B); p < 0.05. Operative intervention for IM in SV/HS is associated with significant interstage attrition and might impact the time to SCPC. SPS is at risk for early failure after IMO. A comprehensive standardized concept can mitigate detrimental implications.

Abstract
BACKGROUND Infants with heterotaxy syndrome (HS) have abnormal lateralization of organs along the right-left body axis. Intestinal rotation abnormalities (IRAs) are a potential source of morbidity and mortality. For this study, our objective was to prospectively observe a cohort of infants with HS and determine the incidence and natural history of IRA. METHODS Infants ≤6 months of age with HS were enrolled in this prospective observational study. Exclusion criteria were other congenital abnormalities that necessitated abdominal surgery. HS was defined as any arrangement of organs that was not situs solitus or situs inversus along with associated congenital heart disease. The investigation for IRA was at the discretion of each participating center. RESULTS Infants were recruited from January 2012 to December 2016. Thirty-eight infants from 7 institutions were included; 22 infants had right isomerism and 16 infants had left isomerism. Twenty-nine infants (76%) were evaluated for IRAs; 21 of 29 evaluations (72%) were abnormal. Eight infants were investigated because of symptoms, and 21 infants were evaluated routinely. The median age at symptom presentation was 46 days (range: 5-171 days). Seven infants had a Ladd procedure; 4 were prophylactic, with 3 as part of a combined procedure, and 3 were emergent. No child suffered acute midgut volvulus over a median follow-up of 1.6 years (range: 0.06-4.93 years). CONCLUSIONS IRAs are common in infants with HS. Infants with symptoms presented by 6 months of age. There was no failure of expectant management resulting in midgut volvulus during a median follow-up of 1.6 years.

Abstract
Aneurysm of the sinus of Valsalva, a rare cardiac condition, results from dilation of an aortic sinus. Sudden aneurysm rupture can trigger rapidly progressive heart failure. We discuss the case of a 57-year-old woman with situs ambiguus, isolated levocardia, and polysplenia who presented with acute-onset heart failure. Transesophageal echocardiograms revealed an aneurysm of the right coronary sinus of Valsalva that had ruptured into the right atrial cavity. The patient underwent successful surgical repair. To our knowledge, this is the first report of a sinus of Valsalva aneurysm in a patient with this combination of congenital abnormalities. We briefly review the association between congenital heart disease, situs ambiguus, and ciliary dysfunction.

Abstract
OBJECTIVE (1) Is screening of intestinal rotational anatomy obligatory in "asymptomatic" patients with heterotaxy? (2) Does detection of an anomaly warrant surgical correction? SUMMARY OF BACKGROUND DATA Heterotaxy is an abnormal arrangement of thoraco-abdominal viscera across a left-to-right axis. Intestinal rotational anomalies are frequent among patients with heterotaxy, but debate exists as to whether they are benign in nature, requiring careful observation alone, or if surgical correction is warranted to prevent obstruction or midgut volvulus. METHODS A systematic review [according to PRISMA guidelines] was conducted using CINAHL, EMBASE, Medline, and Cochrane Databases. Article quality was assessed using MINORS criteria. Conference proceedings and unpublished data were screened additionally. RESULTS Nineteen studies met the eligibility criteria but reporting was adequate for 9. All were observational studies. These included a total of 414 patients managed expectantly, that is, "asymptomatic patients" in whom no intestinal rotation screening was undertaken (group A), 191 cases in whom screening was performed routinely (group B), and 92 patients considered "symptomatic" of potential rotational anomalies and therefore underwent imaging or laparotomy (group C). In group A, 1 patient developed symptoms attributable to malrotation in whom laparotomy confirmed the diagnosis (0.24%). Among groups B and C, 151 had Ladd's operations (53%) and 14 cases of malrotation with obstruction or volvulus were described (4.9%), of which 2 "symptomatic patients" died before laparotomy. Overall surgical complication rate was 17% with 30-day mortality rate of 2.6% to 4.6%. CONCLUSION The evidence base for screening "asymptomatic" patients is weak especially considering the life-limiting comorbidities.

Abstract
Isomerism, also known as heterotaxy, is a unique clinical entity in which there are mirror imaged findings in the thoracic. In the abdomen, the arrangement of organs can be random. The anatomic findings also have functional consequences. Isomerism has been known to increase morbidity and mortality in those with functionally univentricular hearts. The aim of this study was to determine the impact of isomerism on the Glenn hospitalization. Data from the 1997 to 2012 Kids' Inpatient Database were utilized for this cross-sectional study. Admissions during which a Glenn procedure was done were identified. Next, these admissions were separated into those with and without isomerism. Admission characteristics were then compared in a univariate fashion as well as by regression analysis. Length of hospitalization, cost of hospitalization, extracorporeal membrane oxygenation, and inpatient mortality were the outcomes of interest. A total of 4959 admissions with a Glenn procedure were identified. Of these, 450 were associated with isomerism. The median age at which the Glenn procedure was done was 10 and 13 months in those without and with isomerism, respectively. Neither univariate nor regression analysis demonstrated any significant difference in length of hospitalization, cost of hospitalization, need for extracorporeal membrane oxygenation, and inpatient mortality between those with and without isomerism. Isomerism does not impact the characteristics of the Glenn hospitalization. Those with isomerism did tend to be older when they underwent the Glenn procedure.

Abstract
OPINION STATEMENT A hallmark of vertebrate anatomy is asymmetry of structures, especially internal organs, on the left and right side of the body. Heterotaxy syndrome is the combination of correct-sided, and incorrect-sided organs. The establishment of the left-right axis is an early event in vertebrate embryogenesis. Failure to establish this axis has numerous consequences for later development and can result in a wide range of potential defects. Congenital heart disease is among the more frequent and serious problems. Heterotaxy syndrome is diagnosed prenatally with increasing frequency due to improved screening practices. The key to proper management of fetal heterotaxy syndrome is reliable determination of left and right in the fetus, a thorough understanding of associated defects and comprehensive imaging.

Abstract
PURPOSE To assess the usefulness of the relative position of the superior mesenteric artery (SMA) and superior mesenteric vein (SMV) in diagnosing intestinal malrotation in situs anomaly. MATERIALS AND METHODS From January 2004 to April 2015, 33 patients with situs anomalies were enrolled in this study who underwent abdominal USG, CT or MRI as well as upper gastrointestinal series (UGIS) or surgery: situs inversus (n=16), left isomerism (n=10), and right isomerism (n=7); age 21.2±23.2years (mean±standard deviation), range 0-72 years. The intestinal malrotation was confirmed with UGIS and/or operation in 16 patients. Relative positions of the SMV to the SMA were classified into four groups by reviewing abdominal USG, CT, or MRI: right sided, left sided, ventral sided, and dorsal sided. The incidence of malrotation was analyzed for each group. RESULTS In 16 patients with situs inversus, there was reversed SMA-SMV relationship: left sided (n=11) or ventral sided (n=5). One situs inversus patient with ventral sided SMV had intestinal malrotation (6.25%). 17 patients with situs ambiguus showed various SMA-SMV relationships (ventral sided, n=7; left sided, n=5; right sided, n=4; dorsal sided, n=1). Among them, 15 patients (88.2%) had intestinal malrotation. Two patients with normal rotation had either right sided or dorsal sided SMV. CONCLUSION Situs ambiguus was commonly associated with intestinal malrotation with a variable SMA-SMV relationship. Reversal of the mesenteric vascular relationship was observed in situs inversus with normal rotation, not excluding the possibility of intestinal malrotation.

Abstract
OBJECTIVE To assess the role of screening and prophylactic surgery for intestinal rotational abnormalities (IRAs) in asymptomatic patients with heterotaxy. STUDY DESIGN PubMed, Embase, and Cinahl were searched electronically to determine the overall incidence of IRAs in heterotaxy; the detection rate of IRAs associated with screening; the incidence of midgut volvulus in patients without screening; and the incidence of morbidity and mortality after prophylactic and emergency Ladd procedures. Relevant data were computed with a meta-analysis of proportions. Between-study heterogeneity was assessed with the I(2) statistic. RESULTS From 276 papers identified, 24 studies with a total of 1433 patients with heterotaxy were included for systematic review. No randomized study was identified. True incidence of IRA in heterotaxy could not be ascertained through meta-analysis. In patients who underwent screening, the incidence of IRA was 58%. Acute midgut volvulus occurred in 5.8% of those who did not undergo screening. Postoperative mortality after Ladd procedure mainly was associated with cardiac insufficiency, and overall it was significantly greater in the emergency group compared with the prophylactic group (18% vs 5.6%). The complication rate also was greater in case of emergency vs prophylactic abdominal surgery (27% vs 16%); adhesional small bowel obstruction was the most common complication overall (6%). CONCLUSION The screen-detected incidences of IRA and acute midgut volvulus were significantly greater in heterotaxy than the normal population. Prophylactic Ladd procedure was associated with less morbidity and mortality compared with emergency surgery. A long-term prospective randomized trial is needed to define the indication for screening and prophylactic treatment of IRA in heterotaxy.

Abstract
So-called "heterotaxy" is a laterality defect characterized by isomerism of the thoracic organs and random arrangement of the abdominal organs. These findings go beyond anatomic curiosity and have functional implications. It is, thus, of the utmost importance to be able to properly identify these findings. Radiologic studies can be invaluable in determining anomalies in the central nervous, pulmonary, cardiovascular, gastrointestinal, genitourinary, and immunologic systems in patients with isomerism. Here, we review findings associated with isomerism and their importance in the setting of isomerism with the aim of ensuring that radiologists effectively describe findings in these patients and that cardiologists understand the wide variety of congenital malformations that may be present.

Abstract
We report the findings present in 49 postmortem specimens from patients with so-called heterotaxy, concentrating on those found in the extracardiac systems of organs. Also known as bodily isomerism, we suggest that it is important to segregate the syndromes into their isomeric subtypes to be able to make inferences regarding likely extracardiac and intracardiac findings to allow for proper surveillance. We demonstrate that this is best done on the basis of the atrial appendages, which were isomeric in all the hearts obtained from the specimens available for our inspection. The abdominal organs do not demonstrate isomerism, and they show variable features when compared to the isomeric atrial appendages.

Abstract
BACKGROUND The association of heterotaxy with intestinal rotation anomalies is well described. However debate exists with regard optimal management notably should 'asymptomatic' bowel rotation anomalies undergo operation? The present study therefore sought to determine: (1) the risk(s) of volvulus in patients diagnosed with heterotaxy and (2) define morbidity associated with operation for 'asymptomatic' anomalies in a fragile patient cohort with co-existent congenital heart disease. METHODS Medical case record reviews of ALL heterotaxy patients born during January 1993-December 2013 and attending a UK paediatric centre were analyzed. RESULTS Of a total of 92 patients, 16 (17.4%) cases underwent foregut imaging studies. Three examinations were performed in 'symptomatic' patients. Twelve studies reported 'abnormal anatomy' with only five patients undergoing surgical correction. No complication(s) were recorded after Ladd's operation to correct defects. A single fatality occurred within 30 days postoperatively from cardiac failure. In 87 patients in whom Ladd's operation was not undertaken, no single patient developed intestinal volvulus (median length of follow-up 27.2 months, total 446.1 person years). CONCLUSION This study strongly supports a 'watchful waiting' policy for heterotaxy patients. Many children who ultimately die from heart disease may avoid unnecessary abdominal surgery.

Abstract
BACKGROUND Children with heterotaxy syndrome and intestinal rotational anomalies (IRA) are at risk for midgut volvulus and ischemia. Controversy exists regarding risks and benefits of prophylactic Ladd procedures. The purpose of this study is to assess the impact of Ladd procedures on adverse events for children with heterotaxy and IRA. METHODS A retrospective cohort study using the Pediatric Health Information System (PHIS) database was performed. All children with heterotaxy and IRA admitted at age ≤ 30 days and discharged between 1/1/2004 and 1/1/2011 were included with a minimum 2-year follow-up period. The primary outcome was major morbidity, defined as a composite variable for intestinal obstruction/volvulus, ischemia, or resection, or inhospital mortality. Univariable and multivariable analyses were performed. RESULTS There were 325 patients who met the inclusion criteria, including 92 (28%) patients with single ventricles. Mean gestational age was 38.0 ± 2.1 weeks and birth weight was 3.1 ± 0.6 kg. Ladd procedure was performed during initial hospitalization on 188 (58%) children. In multivariable analyses, Ladd procedure on initial hospitalization was associated with a 2.2 times increased odds of adverse events on subsequent admissions (95% CI 1.3-4.0, p = 0.007). CONCLUSIONS Ladd procedure is associated with increased odds of adverse events for children with heterotaxy and IRA.

Abstract
PURPOSE OF REVIEW At present, there is a debate as to the management of malrotation in pediatric patients. This review highlights recent literature including the role of laparoscopy, and the management of asymptomatic patients with and without congenital cardiac disease. RECENT FINDINGS Symptomatic patients are still recommended to undergo open Ladd's procedure. Laparoscopic Ladd's procedure in asymptomatic patients confers a shorter time to tolerating feeds, shorter length of stay, and a decreased rate of bowel obstruction and other complications. It may, however, carry a higher risk of postoperative volvulus. Diagnostic laparoscopy is recommended in asymptomatic patients in whom the diagnosis is uncertain on upper gastrointestinal imaging. Asymptomatic patients with congenital heart disease may be managed with initial observation or operation, based upon individualized risk benefit assessment. If an elective Ladd's procedure is performed, it should take place after palliative cardiac operations have resulted in stable cardiac function. Screening upper gastrointestinal studies in heterotaxy patients may be unnecessary as the reported rates of volvulus in recent studies are low. SUMMARY Laparoscopic Ladd's procedure may be an acceptable alternative to an open procedure for asymptomatic patients. Observation of asymptomatic patients with congenital cardiac disease is a reasonable alternative in selected patients.

Abstract
BACKGROUND Cardiac-specific risks and complications after a Ladd procedure in patients with heterotaxy syndrome (HS) and intestinal rotational anomalies (IRA) are unknown. We sought to (1) describe rates of hospital mortality and early systemic-to-pulmonary (S-P) artery shunt failure after the Ladd procedure in patients with HS and (2) explore risk factors associated with early shunt failure in patients with HS with single ventricle (SV). METHODS This retrospective study included all Ladd procedures performed from January 1999 to December 2012 in patients with HS at a single center. Risk factors investigated for early S-P artery shunt failure included birth weight, gestational age, sex, age at and timing of Ladd procedure relative to cardiac operations, and shunt type. RESULTS Ladd procedure was performed on 54 infants with HS and congenital heart disease. Hospital mortality for the entire cohort was 5.6% (3 of 54 patients). Early shunt failure occurred in 19% (4 of 21) of HS infants with SV. Mean preoperative blood urea nitrogen (BUN) levels were higher in HS infants with early shunt failure (20 versus 12.5 mg/dL; p = 0.054). CONCLUSIONS Patients with SV and HS with S-P artery shunts are at risk for early shunt failure after a Ladd procedure. A higher mean preoperative BUN level is noted in patients with HS and early shunt failure. Careful risk-benefit analysis is indicated before recommending routine elective Ladd procedures in patients with HS.

Abstract
PURPOSE There are no standardized guidelines for screening or management of malrotation in Heterotaxy Syndrome (HS). We sought to review our experience to determine if evidenced based guidelines could be drafted. METHODS A retrospective chart review was performed at our freestanding children's hospital on all patients under one year of age undergoing a Ladd procedure between 2000 and 2011. In addition, all Heterotaxy patients were reviewed during this period. RESULTS Twenty-three Heterotaxy patients and seventy-nine Non-Heterotaxy patients underwent a Ladd procedure. Both groups had a high rate of complication. Heterotaxy was associated with significantly higher mortality 30days after Ladd procedure. In our review, we also identified seventy-six HS patients who did not undergo a Ladd procedure. Among these patients, fourteen had normal intestinal anatomy, five had malrotation, and fifty-seven were never evaluated for intestinal malrotation. No patients with intestinal malrotation or unknown intestinal rotation status suffered midgut volvulus. Average follow-up time was 5.1years. CONCLUSIONS We conclude that prophylactic Ladd procedures in children with Heterotaxy are associated with a high morbidity and mortality. Patients who avoided screening were not exposed to a significant risk of midgut volvulus, and our experience suggests that routine screening of Heterotaxy patients for malrotation should be abandoned.

Abstract
Heterotaxy is a rare disease with high morbidity and mortality. Controversy exists over how to classify these syndromes with most cases stratified into asplenia/polysplenia syndromes or right/left isomerism. In an effort to review comprehensively specific pheonotypes associated with heterotaxy syndromes, we reviewed published cases series, adopted a classification scheme based on spleen status, and evaluated autopsy cases retrospectively with abnormal laterality at our institution. We categorized 116 cases as situs inversus totalis, polysplenia, asplenia, and single right-sided spleen. Cardiovascular abnormalities occurred in 87.1% of polysplenia, 90.5% of asplenia, and all cases of single right-sided spleen. For polysplenia, 48.9% had bilateral bilobed lungs, 87% had right-sided stomach, 58.1% had midline symmetric liver, and 60.4% had malrotated intestines. For asplenia, 51.9% had bilateral trilobed lungs, 86.7% had right-sided stomach, 45.8% had symmetric liver, and 65.5% had malrotated intestines. Atrioventricular septal defects occurred in 91.2% of asplenia compared to 56.8% of polysplenia cases. Eight percent had pulmonary/aortic stenosis or atresia. Double outlet right ventricle was more common in polysplenia (32.6%) compared to asplenia (21.4%). Total anomalous systemic venous return was described in 55.6% of polysplenia and total anomalous pulmonary venous connections in 81% of asplenia cases. Greater than half of the cases had no heterotaxy diagnosis. Although, we found similar heterotaxy-associated characteristics, the frequencies differed from previous studies. We found great variation in how heterotaxy-associated defects were described, diagnosed, and reported. Although there are known associated characteristics with the polysplenia/asplenia syndromes, correct identification requires a standardized approach for diagnosis and reporting.

Abstract
Patients with heterotaxy syndrome (HS) have significant cardiac and extracardiac anomalies that impact outcome. To improve the management of this complex patient population, we performed a comprehensive analysis of their anatomic and clinical features along with an evaluation of resource utilization data. The objectives were to describe anatomic and clinical features of patients with HS syndrome treated at a single center from 1992 to 2011 focusing on the impact of ventricular morphology (univentricular [UV] vs. biventricular [BV]) on clinical outcomes and resource utilization. Clinical and echocardiographic data from patients with HS were abstracted from medical records. Health care costs were indexed to inflation. Seventy-eight patients were identified with HS ranging in age from 1 day to 29 years old. UV morphology was present in 46 patients (59 %), most commonly with right-ventricular dominance (36 of 46). The presence of extra cardiac anomalies did not differ between the UV and BV groups (82 vs. 78 %) nor did morbidities, such as need for enteral tube feedings (47 vs. 25 %) or pacemaker placement (24 vs. 25 %). Mortality was 28 % in the entire cohort: 39 % in univentricuar patients versus 10.5 % in those with biventricular anatomy. Hospital length of stay for medical illnesses was similar in both groups, but length of stay after surgery was significantly longer in UV than BV patients. Among survivors, UV patients had greater median hospital costs (TeX 67,732, p < 0.001), but when this was adjusted for mortality and variable follow-up, there were no differences in health care costs within the first year of life. Significant health care dollars are used to manage children with HS, the majority of which involve expenses related to surgical care. Although patients with biventricular morphology have better survival, morbidity and resource utilization are similar to those for UV patients especially within the first year of life.

Abstract
PURPOSE Heterotaxy syndrome is associated with intestinal abnormalities. We sought to define the gastrointestinal anatomy and determine both the risk of volvulus and benefit of screening upper gastrointestinal fluoroscopy (UGI) in these patients. METHODS Medical records from 2003 until 2011 at Children's Hospital Los Angeles were reviewed in patients with heterotaxy for cardiovascular diagnosis, gastrointestinal symptoms, imaging and surgical arrangement of viscera, perioperative morbidities, and overall mortality. RESULTS 224 patients were identified. Fifteen had polysplenia, 41 had asplenia, 50 had normal splenic morphology, 13 had inversus, and 104 were uncharacterized. UGI was performed in 4 patients for suspected volvulus and 20 for obstructive symptoms. Sixty-two had "screening" UGIs. Of 138 asymptomatic patients without imaging, none developed volvulus during the study period. In 30 patients with duodenojejunal malposition (DJM) who underwent surgery, none had malrotation or narrow mesentery. Eleven developed complications, with 8 requiring reoperation for obstruction. Of 8 patients with malrotation, 7 received a Ladd's procedure, and 2 had volvulus with viable bowel. One patient required reoperation and resection for obstruction. CONCLUSION While rotational abnormalities are common in heterotaxy, risk of volvulus is low. Following operation, the risk of bowel obstruction and of need for reoperation is higher. We advocate avoiding operation in the asymptomatic patient.

Abstract
Isolated levocardia (IL) is a rare condition of situs anomaly in which there is a normal left-sided heart (levocardia) with dextro position of the abdominal viscera. IL has been reported in children and adults with complex cardiac defects, whereas there are only few published reports regarding the prenatal diagnosis of IL. We report two prenatal cases of IL diagnosed by ultrasonography and magnetic resonance imaging (MRI). In both cases, fetal cardiac function remained within the normal range throughout pregnancy, and no treatment for the heart was required after birth. For the dextro position of abdominal viscera, one case was followed without any surgical procedure, but the other case required prophylactic operation due to malrotation of the small intestine. Although the prognosis of IL largely depends on the severity of associated cardiac anomaly, future bowel obstruction caused by intestinal malrotation may also be life-threatening. In this respect, prenatal diagnosis of IL is important, even when there is no associated cardiac structural anomaly. If IL is suspected in routine fetal ultrasonography, MRI may be recommended to obtain more detailed information on the anatomy of abdominal viscerae, and careful observation for bowel problems is required, especially after oral nutrition is started.

Abstract
The complex and sometimes controversial subject of malrotation and midgut volvulus is reviewed commencing with the 19th-century Bohemian anatomist, Václav Treitz, who described the suspensory muscle anchoring of the duodenal-jejunal junction in the left upper quadrant, and continuing with William Ladd, the 20th-century American "father of pediatric surgery" who pioneered the surgical treatment of midgut volvulus. In this review, we present the interesting history of malrotation and discuss the current radiologic and surgical controversies surrounding its diagnosis and treatment. In the symptomatic patient with malrotation and possible midgut volvulus, prompt diagnosis is critical. The clinical examination and plain film are often confusing, and delayed diagnosis can lead to significant morbidity and death. Despite recent intense interest in the position of the mesenteric vessels on US and CT scans, the upper gastrointestinal series remains the fastest and most accurate method of demonstrating duodenal obstruction, the position of the ligament of Treitz, and, if the contrast agent is followed distally, cecal malposition. Controversy exists over the management of asymptomatic patients with malrotation in whom the diagnosis is made incidentally during evaluation for nonspecific complaints, prior to reflux surgery, and in those with heterotaxy syndromes.

Abstract
How best to analyse and describe the features of the situation commonly known as "visceral heterotaxy" remains controversial. Much of the disagreement devolves on how to deal with the concept of isomerism. In the opinion of some, the concept of bilateral right-sidedness and bilateral left-sidedness, while useful in helping to remember which abnormalities are likely to occur in asplenia or polysplenia, should not be granted the status of a specific "situs", since there are numerous examples of exceptions to these patterns. On the other hand, those who favour the concept of isomerism point out that, when describing only the heart, and taking the structure of the atrial appendages as the starting point for analysis, basing this on the extent of the pectinate muscles relative to the atrioventricular junctions, then the only possible arrangements for the appendages are the usual one, its mirror-image, and the two situations in which appendages of comparable morphology are found on both sides of the heart, these being the arrangements of right or left isomerism. It is certainly the case that the arrangement of the organs is not always in harmony with the arrangement of the atrial appendages, but those circumstances, in which there is disharmony, can readily be described by paying specific attention to each series of organs. On this basis, in this review, we describe the approach to heterotaxy, and isomerism of the atrial appendages, in terms of the genetic background, the diagnosis, and outcomes after cardiac surgery. Attention is given to the various diagnostic modalities, including fetal and postnatal echocardiography, recent tomographic and magnetic resonance imaging techniques, and the time-honoured approach using angiography.
