EXTERNALLY, THE HUMAN BODY appears symmetric; if a line is drawn down the middle of the body, each side appears identical. However, this is not true of the internal anatomy. For example, there is one heart, which lies in the left chest, one liver, in the right abdomen, and one stomach, in the left abdomen. The term situs refers to the position or location of an organ, specifically, the position of the atria and abdominal viscera in relation to the midline of the body.1 There are three types of situs: solitus, inversus, and ambiguous. Situs solitus refers to the normal arrangement of organs, with the right atrium, liver, gallbladder, trilobed lung, and inferior vena cava on the right side and the left atrium, stomach, spleen, bilobed lung, and descending aorta on the left side (Figures 1–3). Situs inversus totalis refers to a mirror image reversal of the normal position of the internal organs (Figures 4 and 5). 1 The incidence of situs inversus totalis is 1 in every 8,000 to 25,000 births, and the condition is most often diagnosed by radiographic examination.2Situs ambiguous, often referred to as heterotaxia, is the random arrangement of the internal organs and is associated with splenic abnormalities and congenital heart disease.3 The purpose of this column is to discuss the embryology, pathophysiology, and diagnosis of situs inversus totalis and to review a case study with radiographic findings.

Introduction. Situs inversus totalis (SIT) represents a total vertical transposition of the thoracic and abdominal organs which are arranged in a mirror image reversal of the normal positioning 1. We presented a successful pre-dialysis kidney transplantation from a living sibling donor with SIT and the longest donor follow-up period, along with analysis of the reviewed literature. Case report. The pair for pre-dialysis kidney transplantation included a 68-year-old mother and 34-year-old daughter at low immunological risk. Comorbidities evidenced in kidney donors with previously diagnosed SIT, included moderate arterial hypertension and borderline blood glucose level. Explantation of the left donor kidney and its placement into the right iliac fossa of the recipient were performed in the course of the surgical procedure. A month after nephrectomy, second degree renal failure was noticed in the donor. A 20-month follow-up of the donor?s kidney and graft in the recipient proved that their functions were excellent. Conclusion. In donors with previously diagnosed SIT the multidisciplinary approach, preoperative evaluation of the patient and detection of possible vascular anomalies are required to provide maximum safety for the donor.

In 1926, the famous American pediatric cardiologist, Dr. Helen B. Taussig, observed that in situs inversus totalis (SIT) main gross anatomical structures and the deep muscle bundles of the ventricles were a mirror image of the normal structure, while the direction of the superficial muscle bundles remained unchanged (H. B. Taussig, Bull Johns Hopkins Hosp 39: 199–202, 1926). She and we wondered about the implication of this observation for left ventricular (LV) deformation in SIT. We used magnetic resonance tagging to obtain information on LV deformation, rotation, and torsion from a series of tagged images in five evenly distributed, parallel, short-axis sections of the heart of nine controls and eight persons with SIT without other structural (cardiac) defect. In the controls, during ejection, the apex rotated counterclockwise with respect to the base, when looking from the apex. Furthermore, the base-to-apex gradient in rotation (torsion) was negative and similar at all longitudinal levels of the LV. In SIT hearts, torsion was positive near the base, indicating mirrored myofiber orientations compared with the normal LV. Contrary to expectations, torsion in the apical regions of SIT LVs was as in normal ones, reflecting a normal internal myocardial architecture. The transition zone with zero torsion, found between the apex and base, suggests that the heart structure in SIT is essentially different from that in the normal heart. This provides a unique possibility to study regulatory mechanisms for myocardial fiber orientation and mechanical load, which has been dealt with in the companion paper by Kroon et al.

Situs inversus totalis (SIT) is a rare congenital condition in which the usual position of the organs is reversed from left to right as a mirror image of the normal situation. Due to the abnormal transposition, this represents a technical challenge for the surgeon. In the present study, right hemihepatectomy via the anterior approach was performed for a 68-year-old hepatocellular carcinoma (HCC) patient with SIT. SIT was diagnosed by chest X-ray and computed tomography. The tumors were located in segments VIII and VI of the liver, and there was no metastasis to the lymph nodes and distant organs. Hemihepatic vascular inflow occlusion was performed using the selective intra-Glissonian approach. The middle hepatic vein was preserved under the guidance with intraoperative ultrasonography. The present case suggests that right hemihepatectomy via the anterior approach may be a safe, feasible, and effective procedure for HCC patients with SIT.

Situs inversus totalis is a rare, congenital condition that is characterized by the development of the thoracic and abdominal viscera in a mirror image to their normal orientation. This case report describes the condition in a 4-year-old, spayed female Doberman pinscher that was evaluated for dyspnea following sedation. Radiography confirmed a diaphragmatic hernia. Situs inversus was discovered during surgical correction. The diaphragmatic rent was repaired, and the dog was clinically normal at recheck 13 months after surgery.

A 70-year-old man, diagnosed with severe mitral regurgitation and moderate tricuspid regurgitation with situs inversus totalis, was referred to our hospital. A minimally invasive approach via a minithoracotomy was performed. The mitral valve was repaired with the loop technique and ring annuloplasty. With an asymmetric shape of the tricuspid valve, the use of a conventional rigid ring was not feasible. Therefore, flexible ring annuloplasty had to be performed. The minimally invasive approach for mirror-image anatomy did not pose an unusual technical challenge. It was safely performed in the context of situs inversus totalis.
