Minimally invasive mitral valve replacement and concomitant Cox-Maze IV procedure using radiofrequency energy in situs inversus totalis: A case report.

INTRODUCTION: Situs inversus totalis (SIT) is an uncommon congenital condition characterized by total transposition of abdominal and thoracic viscera. Performing minimally invasive cardiac surgery on individuals with SIT requires different surgical planning because of the unfamiliar positions of the heart and great vessels.

PRESENTATION OF CASE: A 52-year-old female was admitted to our center with palpitations and dyspnea on exertion. Chest X-ray showed dextrocardia. Echocardiography and chest computerized tomography (CT) revealed SIT with severe rheumatic mitral valve disease.

DISCUSSION: Pre-operative three-dimensional (3D) chest CT reconstruction was helpful in surgical planning and management of cardiopulmonary bypass (CPB). Mitral valve replacement and concomitant atrial fibrillation (AF) ablation using radiofrequency (RF) energy via left mini-thoracotomy was successfully performed on the patient.

CONCLUSION: Minimally invasive approach can be safely and effectively employed in patients with SIT.
