- Abstract: Tricuspid annulus has an asymmetric three-dimensional structure with the posteroseptalportion lowest toward the apex from the right atrium and the anteroseptal portion the highest. The tricuspid annulus of a patient with situs inversus has a mirror image of a patient with situs solitus, and the posteroseptal and the anteroseptal portion remains the lowest and the highest toward the apex, respectively, as the situs solitus. Therefore, we assumed that the posteroseptal portion would become higher and the anteroseptal portion would become lower using a conventional three-dimensional rigid ring turned over for tricuspid regurgitation in the situs inversus, and the coaptation of the three leaflets would be poor. In this case, we performed tricuspid annuloplasty using a tricuspid flexible band, mitral valve plasty, left atrial plication, left atrial appendage closure for a situs inversus dextrocardia patient with tricuspid regurgitation, mitral regurgitation, and chronic atrial fibrillation.
