Objective. Studying the possibility of replacing the tricuspid valve with a pericard.

Material and methods. In the laboratory condition on the pig heart right atrium dissected. According to author’s calculations – the diameter of the fibrous ring is equal to the length of the base of the septal leaflet (a), with a margin of 5 mm, to create commissures and the leaflets bulge. It is believed that the size of the front flap corresponds to the bottom of the meter (c), which would correspond to a+5, with a margin of 5 mm. For the rear flap (b) – a–5, or b=2/3c = c–1/3c. Radius (r) is d/2+5, the length of the chord (L) is (r+5)/3.

Results. The average time required for each valve prosthesis 15±7 minutes. Pericardial patch size needed for tricuspid valve (TV) reconstruction 4±2 cm. Hydraulic probe showed good valve competence in partial or full valve replacement, and sealed suture line (V=80–120 ml water). Neoleaflets are mobile, not narrowing the AV channel, and coaptation area is located below the level of TV annulus.

Conclusion. TV reconstruction with pericardium (autologous or bovine) can be considered as an alternative to valve replacement. This methodology is a full TV cusps replacement can be used in clinical practice.
