Comparative Study
BACKGROUND
To investigate the differences in cardiovascular disease, extracardiac anomalies and outcomes between fetuses with levocardia and dextrocardia.
METHODS
Clinical demographics, prenatal features, postnatal characteristics and the outcomes of fetuses with levocardia or dextrocardia were recorded and analyzed.
RESULTS
Sixty-five fetuses with dextrocardia and thirty-eight fetuses with levocardia were enrolled. Right ventricle outlet obstruction, atrioventricular septal defect and intestinal malrotation were common in both groups. Univentricular physiology, transposition of the great arteries and esophageal atresia were more frequent in fetuses with levocardia, whereas abnormal pulmonary venous connection, double outlet of right ventricle, left ventricle outlet obstruction and brain abnormalities were more frequent in the dextrocardia group. The accuracy of evaluating cardiac malformations was high, but the sensitivity in assessing extracardiac abnormalities was low.
CONCLUSIONS
Although the disorders have certain overlapping features, there are several differences between fetuses with levocardia and dextrocardia. These findings might improve patient counseling and perinatal management.

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.

Review
Isolated levocardia with situs inversus, or ILSI, is a rare anomaly with a reported incidence of 1:22,000 in the general population and from 0.4% to 1.2% of all patients with congenital heart diseases. It is commonly associated with both congenital heart disease and splenic abnormalities, either asplenia or polysplenia. The prognosis is poor, and only about 5% to 13% of patients survive more than 5 years. The case described here, which had computed tomographic findings, is the first case reported with multiple malignancies associated with ILSI. This patient, at 73 years of age, is the second longest survivor reported in the literature.

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.

BACKGROUND
Cryoballoon-based pulmonary vein isolation (cbPVI) is a standardized treatment of atrial fibrillation. In complex anatomies, radiofrequency ablation (rfPVI) is usually preferred. We describe the first cbPVI in a rare patient with SI and levocardia.
CASE SUMMARY
A 41-year-old male patient with paroxysmal atrial fibrillation was referred to our clinic after a previous, unsuccessful cbPVI procedure. Observation of an atypical lead-wire position due to an abnormal anatomy of the inferior vena cava led to its initial termination. A subsequent thoraco-abdominal computed tomography revealed situs inversus abdominalis and levocardia and the procedure was re-attempted in our clinic. Transseptal puncture (TSP) was guided via transoesophageal echocardiography and fluoroscopy, using a SL0-Sheath and a standard BRK-needle. Advancement of the sheath initially failed but after additional dilatation with an Inoue dilator, transseptal passage of the sheath was successful. Due to the unusual antero-cranial TSP, the septal pulmonary veins (PV) contrasted poorly. After repeat TSP, a steerable FlexCath Advance sheath was introduced into the left atrium using an Amplatz Super Stiff guidewire. Subsequently, all PV were intubated with the Achieve catheter, over which a 2nd generation cryoballoon was introduced. Despite the practical challenges in this case, all PV were isolated.
DISCUSSION
The main challenges include the achievement of transseptal access and manipulation of the cryoballoon to achieve a patent seal of the pulmonary veins. cbPVI eliminates the need for constant re-positioning of the ablation catheter and might facilitate the creation of durable lesions under such difficult anatomical conditions.
