RESUMEN
A 59-year-old man, diagnosed with severe mitral regurgitation, moderate tricuspid regurgitation, and chronic atrial fibrillation with situs inversus totalis, was referred to our hospital. A median sternotomy approach was performed. The surgeon operated from the left side of the operating table, and had an excellent exposure to the mitral and tricuspid valves during the operation. The mitral valve was repaired with the posterior cusp plication technique and ring annuloplasty. The tricuspid valve was repaired with ring annuloplasty. We use a conventional semi rigid ring turned over, because the tricuspid valve has an asymmetric configuration. FullMAZE, and left atrial appendage closure were performed, too. The postoperative course was uneventful.
