Simplified Technique of Conventional Cholecystectomy in a Patient with Situs Inversus Totalis: A Case Report from Nepal

Introduction: Situs inversus is a rare autosomal recessive disorder occurring in 1:5,000 to 1:20,000 indiviuals. Cholecystectomy is a standard treatment for symptomatic gallbladder stone. We report a case of cholelithiasis in patient with inversus totalis who underwent cholecystectomy. Case presentation: A 48 years old obese female patient with dextrocardia and hypertention presented with a recurrent left upper abdominal pain for two years. Ultrasound abdomen showed gallbladder stone. Conventional cholecystectomy was done with a small left subcostal incision. The postoperative period was uneventful and the patient was discharged on 3rd post operative day. Conclusion: Cholecystectomy is the treatment of choice in patients with a left sided gallbladder stone, like in normal gallbladder and it is safe.

A RARE CASE OF DEXTROCARDIA AND SITUS INVERSUS WITH TETRALOGY OF FALLOT IN A 23-YEAR-OLD FEMALE: A CASE REPORT

Tetralogy of Fallot (TOF) is commonly identified cyanotic congenital cardiac anomaly; however, its affiliation with dextrocardia and situs inversus is very rare. We describe a case of dextrocardia and situs inversus associated with TOF in a 23-year old girl who arrived with central shunt at the age of 17 years and later for total surgical correction with magnificent outcomes.

309 Upgrading from a dual-chamber pacemaker to a cardiac resynchronization therapy defibrillator in situs inversus totalis with dextrocardia following mitral valve replacement and tricuspid annuloplasty using a left-sided approach

A 71-year-old female patient was referred to our centre to upgrade a dual-chamber pacemaker to a cardiac resynchronization therapy defibrillator (CRT-D) following the detection of worsened systolic function (ejection fraction: 25–30%) via transthoracic echocardiography. The patient had situs inversus totalis with dextrocardia. She had undergone mitral valve replacement and tricuspid annuloplasty in July 2019, with a concomitant left upper pulmonary lobectomy for neoplasm, detected at cardiac tomography incidentally. In January 2020, we performed an upgrade of the preexisting device to a CRT-D system because the patient developed heart failure, reduction in systolic function, and numerous nonsustained ventricular tachycardias. The right ventricular lead that had been previously implanted was extracted. To facilitate the intervention, we decided to flip the fluoroscopic image, obtained with a right-anterior oblique view, by 180 °C (right–left), creating the optical impression of a levocardial position.
