Review
Positional abnormalities per se do not require treatment, but in their place, the accompanying pulmonary pathology in dextroposition patients and pathophysiologic hemodynamic abnormalities resulting from multiple defects in patients with cardiac malposition should be the focus of treatment. At the time of the first presentation, treating the pathophysiologic aberrations caused by the defect complex, whether it is by improving the pulmonary blood flow or restricting it, is the first step. Some patients with simpler or single defects are amenable to surgical or transcatheter therapy and should be treated accordingly. Other associated defects should also be treated appropriately. Biventricular or univentricular repair dependent on the patient's cardiac structure should be planned. Complications in-between Fontan stages and after conclusion of Fontan surgery may occur and should be promptly diagnosed and addressed accordingly. Several other cardiac abnormalities unrelated to the initially identified heart defects may manifest in adulthood, and they should also be treated.

Review
A significant number of patients with dextrocardia and other cardiac malpositions have other congenital heart defects (CHDs). The incidence of CHDs in subjects with cardiac malpositions is significantly greater than that in normal children, and the prevalence varies with the associated visceroatrial situs. The most useful approach to diagnosis is segmental analysis. Firstly, dextroposition should be excluded. In segmental analysis, the visceroatrial situs, ventricular location, status of atrioventricular connections, the great artery relationship, and conotruncal relationship are determined with the use of electrocardiogram (ECG), chest X-ray, and echocardiographic studies, and, when necessary, other imaging studies, including angiography. Following identification of the afore-mentioned segments, the associated defects in the atrial and ventricular septae, valvar and vascular stenosis or atresia may be determined by a review of the historical information, physical examination, and analysis of chest roentgenogram, ECG, and echocardiographic studies. Along the way, a pictorial rendition of the terminology and diagnosis of cardiac malpositions is undertaken.

BACKGROUND
Situs inversus with levocardia is a rare anomaly in which the heart is present in the left chest but the abdominal viscera are transposed. It is caused by a single incomplete penetration of an autosomal recessive gene. It is unclear what exactly causes situs inversus with levocardia. Even if situs inversus can be identified following a comprehensive physical examination, it is now possible to validate the results and search for further information and pathologies since medical imaging is so widely accessible.
CASE
A 15-year-old Oromo male child from a remote area of Bale Zone presented to the Goba Referral Hospital's medical emergency outpatient department complaining of periumbilical pain that had persisted for 4 months. He frequently came to our hospital and was admitted three times with the same problem. Objectively, there was tenderness over the left lower quadrant and periumbilical area. The sonographic evaluation discovered the transposition of the liver and spleen with cardiac apex on the left side. He received conservative treatment with ceftriaxone 1 g intravenous twice a day and metronidazole 500 mg intravenous for 5 days, and he went home improved.
CONCLUSION
Isolated levocardia is a rare form of situs inversus in which the heart is in the traditional levo position while the abdominal organs are in the dextro position. What causes situs inversus with levocardia is unknown. Despite the fact that situs inversus can be diagnosed after a thorough physical examination, medical imaging has allowed us to confirm the findings as well as understand more about diseases. Due to the severity of an underlying heart defect, situs inversus with levocardia has a dismal prognosis.

Imaging of dextrocardia in humans requires an understanding of the orientation of the heart chambers and walls. There are many types of cardiac malpositioning, such as dextrocardia (with or without situs inversus), mesocardia, and levocardia. Myocardial perfusion scintigraphy of dextrocardia has been explained in case reports and imaging atlases; however, myocardial viability assessment using nuclear medicine imaging techniques is less documented in the literature. In 2 cases of dextrocardia with situs inversus and 1 case of mesocardia, myocardial viability was assessed using Tc-sestamibi rest perfusion scintigraphy and F-FDG PET. Cardiac SPECT images of dextrocardia with situs inversus were acquired using the feet-first supine position with a 180° arc from left anterior oblique to right posterior oblique, whereas a right-lateral-to-left-lateral arc was used for mesocardia. The processing and reconstruction were done by entering the dataset for the feet-first supine position and repeating after entering the dataset for the feet-first prone position. The 2 sets of reconstructed images were compared for orientation of walls and cardiac chambers. The first processing, using the feet-first supine position, revealed an interchanged septum and lateral wall in reconstructed images of dextrocardia with situs inversus. This interchange was corrected by changing the position to prone during processing of the rest perfusion and PET raw data. The display of cardiac slices in various axes matched the conventional nomenclature for the septum and lateral wall, leading to easy interpretation. However, this change was not required in the mesocardia, for which the location of the heart chambers was not interchanged. Because the acquisition protocol for SPECT is a semicircular orbit, the various types of dextrocardia require careful selection of the arc, with the patient positioning kept feet-first supine. Processing and reconstruction of data by changing the patient position to prone was found to be most useful method of matching the septum and lateral wall orientation for interpretation of images.

Tetralogy of Fallot is the most common cyanotic congenital heart disease. It consists of right ventricular outflow tract obstruction, a ventricular septal defect, abnormally located aorta and right ventricular hypertrophy. It usually occurs as an isolated anomaly with a normally placed heart and abdominal viscera. We present a case of a 19 years old female who presented with a prolonged history of shortness of breath (SOB) and cyanosis. After undergoing echocardiography and cardiac computed tomography angiogram (CTA), she was diagnosed to be a case of Tetrology of Fallot (TOF) in association with situs inversus with levocardia also termed 'isolated levocardia'. The patient underwent surgical correction and she was asymptomatic with no residual cardiac defects on follow up after 6 months. Isolated levocardia is a rare condition that is usually associated with severe cardiac defects and a low life expectancy in untreated patients. It is unusual for it to be diagnosed in adults as in our case.

A newborn without prenatal diagnosis, with bronchial and abdominal situs inversus in levocardia, was referred to our hospital for accurate evaluation; echocardiography showed venoatrial connections in mirror-image arrangement, atrioventricular (AV) discordance, and double-outlet right ventricle (DORV). Additional cardiac malformations were double upper caval district, atrial communication, subpulmonary interventricular communication, and moderate subvalvular and valvular pulmonary stenosis. Few days after birth, the patient presented low oxygen saturation and the heart team decided for a palliative surgery. We describe a very rare case in a newborn with bronchial-abdominal mirror imagery, AV discordance, and DORV in levocardia.

INTRODUCTION AND IMPORTANCE
Obesity is a worldwide pandemic and is closely associated with an increased risk of comorbidities and overall mortality. Surgery has emerged as an essential strategy to ameliorate obesity-attributable comorbidities and as a powerful weight-loss tool. Due to the increasing number of obese patients predicted to elect surgery, individuals with rare anomalies such as situs inversus can be expected.
CASE PRESENTATION
We present the case of a 49-year-old woman with situs inversus with levocardia. She had a high BMI and was admitted for bariatric surgery. After several adjustments to our technique, the procedure was completed without complications.
CLINICAL DISCUSSION
Laparoscopic bariatric surgeries are highly demanding; variations from the normal anatomy could challenge the medical team.
CONCLUSION
Preoperative diagnosis and highly trained surgeons is of paramount importance to adequately treat every patient.

OBJECTIVE
Congenital pericardial defect (CPD) is a rare entity with an estimated frequency of 0.01%-0.04%. The recognition of this anomaly is important since it can be associated with serious complications. The aim of this study and review was to describe clinical and imaging features that help in establishing the diagnosis of this condition.
METHODS
We retrospectively reviewed all adult patients at the Cleveland Clinic Health System with the diagnosis of CPD between the years 2000 and 2015. Baseline clinical characteristics, clinical manifestations, ECG, transthoracic echocardiography (TTE), cardiac CT and cardiac magnetic resonance (CMR) images were reviewed.
RESULTS
Eight patients were included in the study. Sixty-three percent of patients were males with mean age at diagnosis of 48 years, 63% had a partial pericardial defect on the left side and right ventricular (RV) dilation on TTE. Three patients had CMR. Levocardia was present in all CMRs. One patient had greater than 60° clockwise rotation and none of the CMRs showed ballooning of the left ventricular apex. One patient required surgical pericardioplasty. The remaining seven patients had a median follow-up of 17.3 months (5-144.9 months) and all remained asymptomatic.
CONCLUSION
CPDs are more likely to be partial on the left side and patients often have RV dilation on the TTE and levocardia on CMR. Most patients remain stable and do not require surgical intervention. TTE and CMR play an important role in making the diagnosis of this anomaly.

BACKGROUND
Bilateral congenital diaphragmatic hernia (CDH) is very rare. A few studies have reported the pathogenic role of 5p in CDH.
CASE PRESENTATION
A 23-year-old primigravida Japanese woman was referred for the following abnormal findings at 33 weeks of gestation: polyhydramnios, macroglossia, talipes equinovarus, and levocardia. A marker chromosome was detected by amniocentesis. Fluorescence in situ hybridization with whole chromosome paint 5 and nucleolus organizer region probes confirmed its origin from chromosome 5 and an acrocentric chromosome. The karyotype of the fetus was diagnosed as 47, XY, +mar. ish +mar(WCP5+). At 39 + 5 weeks, a 2462 g male infant was delivered, with a specific facial configuration. Bilateral CDH, hypoplasia of the corpus callosum, atrial septal defect, and hypothyroidism were also detected in the baby. The karyotype of the peripheral blood was consistent with that of the amniocentesis.
CONCLUSION
Genes coded on 5p might be associated with the pathogenesis of CDH; however, further investigation is required.
