A position-adjustable device for treatment of tricuspid regurgitation is proposed. The position-adjustable device for the treatment of tricuspid regurgitation is used to verify whether heart failure of the right ventricle may occur, and includes: a first catheter provided with a first lumen； a second catheter inserted into the first lumen and provided with a second lumen into which a guidewire is inserted； an adjusting part coupled to a lower side of the first catheter and the second catheter, wherein the adjusting part is provided with a first direction-adjusting device adjusting a direction of an upper end of the first catheter； and a blocking part coupled to an upper outer side surface of the second catheter, capable of adjusting a position according to a movement of the upper end of the first catheter, and obliquely penetrating and blocking the orifice formed by the incomplete closing of the tricuspid valve.
