'Four-leaflet clover repair' of severe tricuspid valve regurgitation due to complex lesions.

We report the case of a 52-year-old man who was referred to surgery because of severe mitral and tricuspid regurgitation of Barlow's disease. In particular, the tricuspid valve was a 'four-leaflet valve' due to the presence of a small accessory leaflet between the septal and the posterior leaflets. The valve insufficiency was determined by prolapse of all leaflets (in particular of the anterior and posterior ones) associated with annular dilatation. The patient underwent both mitral and tricuspid valve repair. The tricuspid regurgitation was corrected by stitching together the middle point of the free edges of the tricuspid leaflets producing a 'four-leaflet clover-shaped' valve. Surgical and echocardiographic images of the repaired valve are reported.
