BACKGROUND Poorly controlled ventricular rate associated with atrial fibrillation (AF) leads to tachycardia-induced left ventricular dysfunction. Atrioventricular (AV) nodal ablation and cardiac pacing is the standard of care in refractory congestive heart failure (CHF) due to AF with moderate to rapid ventricular response that failed conventional medical therapy. If the patient is not a candidate for AF ablation with pulmonary vein isolation and elimination of AF foci, this is an effective approach, but it does have some challenges when done in a patient with dextrocardia and situs inversus...

Symmetry is appealing, be it in architecture, art or facial expression, where symmetry is a key feature to finding someone attractive or not. Yet, asymmetries are widespread in nature, not as an erroneous deviation from the norm but as a way to adapt to the prevailing environmental conditions at a time. Asymmetries in many cases are actively selected for: they might well have increased the evolutionary fitness of a species. Even many single-celled organisms are built asymmetrically, such as the pear-shaped ciliate Paramecium, which may depend on its asymmetry to navigate towards the oxygen-richer surface of turbid waters, at least based on modeling...

Polysplenia syndrome is a rare condition (about 2.5:100,000 live births) wherein a person has two or more spleens with accompanying various thoracic and abdominal organ abnormalities. Polysplenia is usually associated with situs ambiguous, while polysplenia with situs inversus is very rare. Herein, we report a rare case of incidentally found polysplenia syndrome combined with situs inversus in a 59-year-old female who also had an interrupted inferior vena cava (IVC) with azygos continuation, patent ductus arteriosus (PDA), and variations in the aortic arch branches...

Situs inversus totalis (SIT) is a rare anatomic anomaly in which organs in the chest and abdomen exist in a mirror image reversal of their normal positions. SIT can complicate surgical procedures, and few reports have described laparoscopic surgery for colorectal cancer in patients with SIT. Here, we report a case of successful laparoscopic surgery in a patient with SIT and sigmoid colon cancer. Laparoscopic sigmoidectomy involved colonic mobilization with high ligation of the inferior mesenteric vessels and complete mesocolic excision...

Nephronophthisis is a progressive disease that affects development of the renal tubules and leads to end stage renal disease. Many affected children have isolated renal disease; however, there can be additional manifestations including heart defects, liver fibrosis, brain malformations, and situs inversus. There is no way to slow or modify the disease. We describe a patient who presented at birth with cholestatic jaundice and decreased kidney function, found by exome sequencing to have two NPHP3 variants. Her clinical status deteriorated rapidly, and two disease-modifying agents were given in hopes of slowing disease progression, the arginine vasopressin type II receptor antagonist tolvaptan to stabilize her renal function and isosorbide dinitrate to manage her poorly controlled hypertension...

INTRODUCTION: Laparoscopic Roux-en-Y gastric bypass (LRYGB) has proven over the years to be one of the most effective bariatric procedures. It is highly technical, and therefore is mostly performed by bariatric and metabolic surgeons. Although Situs Inversus Totalis (SIT) is a very rare congenital condition, surgeons do occasionally have to operate intra-abdominally on those patients, consequently facing some challenges related to the unusual anatomy. CASE PRESENTATION: We describe a rare case of LRYGB for chronic morbid obesity on a 43 year old patient with pre-operative diagnosis of situs inversus totalis without Kartagener's syndrome, using slight modification from the usual technique based on anatomical correlation without the need to change the surgeon's position or switching trocar placements as described in previous papers...

Acute appendicitis is the most common cause of acute abdominal pain, requiring emergency surgery. Approximately one third of cases have pain unexcepted location due to its various anatomical location. Acute appendicitis is a very rare cause of left lower quadrant pain; if it occurs, a few congenital anomalies should be considered such as Situs Inversus totalis and Midgut Malrotation (MM). MM is a rare congenital anomaly; it occurs due to error in process of rotation or fixation of intestines around the superior mesenteric vessels and it refers to nonrotation or incomplete rotation of intestines...

RATIONALE: Situs inversus totalis (SIT) is a rare anatomical variation of the internal organs, and solid pseudopapillary tumor of the pancreas (SPTP) is a rare tissue type of pancreatic tumors, classified as benign or low-grade malignancy. However, to our knowledge, a patient with SIT and SPTP is extremely rare and has never been reported. PATIENT CONCERNS: We retrospectively analyzed a case of SIT with SPTP in a 45-year-old woman. The main complaints were abdominal pain and sensation of heaviness for 2 weeks...

Primary ciliary dyskinesia (PCD) is a rare disorder with impaired ciliary function resulting in a spectrum of clinical manifestations of varying severity. PCD affects approximately one in every 20,000 individuals with a reported prevalence between 1:4000 and 1:50,000. Due to its nonspecific clinical features, the condition is usually diagnosed late in its course, unless situs inversus (SI) or organ laterality defects are discovered at imaging. A small subset of patients with PCD display associated organ laterality defects, different from the classical SI totalis...

Endoscopic retrograde cholangio-pancreatography (ERCP) is an important tool for treatment of pancreaticobiliary diseases. However, ERCP may be difficult in patients who have altered gastrointestinal anatomy due to congenital or surgical reasons. A 40-year-old male with HIV infection presented with abdominal pain following abdominal trauma. The patient was diagnosed to have traumatic pancreatic injury and underlying situs inversus. The pancreatic fluid collection was drained using radiology guided pigtail placement done for the symptoms of abdominal pain and vomiting...

A 72-year-old woman was examined by F-FDG PET/CT, showing pathologic tracer uptake in the gallbladder. PET/CT also depicted condition of situs inversus totalis, with dextrocardia, liver on the left side and spleen on the right side of the body. These findings were essential to plan and develop laparoscopic cholecystectomy, which diagnosed cholangiocarcinoma. The recognition of anatomical variants and abnormalities by means of hybrid PET/CT imaging is essential in order to plan the best therapeutic approach.

A 58-year old man was referred to our rheumatology department because of arthralgia and generalized stiffness. His was already known with Kartagener syndrome with situs inversus. Physical examination revealed multiple painful enthesis and stiffness of the thoracic spine. There were no signs of arthritis. Diffuse idiopathic skeletal hyperostosis (DISH) was suspected. An x-ray of the thoracic spine revealed continuous ossification between five contiguous vertebral bodies (A). The lateral view showed extensive ossification of the anterior longitudinal ligament (B)...

Major aortopulmonary collateral arteries can influence the postoperative course of arterial switch operation, with heart failure being the common clinical presentation. A relatively rare presentation of an aortopulmonary collateral artery in the form of persistent postoperative pulmonary hemorrhage was encountered after an uneventful arterial switch operation in a neonate with transposition of the great arteries, intact interventricular septum, and situs inversus totalis. The aortopulmonary collateral artery was coil embolized with a successful outcome...

BACKGROUND: Situs inversus is a rare congenital condition that is currently classified into two types: complete situs inversus (situs inversus totalis, SIT) and partial situs inversus (situs inversus partialis, SIP). In SIP patients, some organs are inverted and others are in their expected position, and individual patient variation in organ position increases surgical difficulty. Several surgeons have performed laparoscopic or robotic surgeries in situs inversus patients, but almost all were SIT patients...

BACKGROUND: Esophagectomy in situs inversus is challenging. With long-segment supercharged reconstruction, it becomes more perplexing and multidisciplinary surgical skills are needed. Challenges met and the surgical technique used is presented in this case report. METHODS: The case of a 49-year old patient with situs inversus abdominus and a locally advanced distal esophageal adenocarcinoma extending to the stomach is presented. RESULTS: Following neoadjuvant chemotherapy and due to inability to use the stomach as a conduit, a thoracoscopic total esophagogastrectomy with long-segment reconstruction was performed...
