Abstract: there are three common methods in the treatment of the three cusps: Vega, De, Carpentier, and so on.
The three tricuspid insufficiency of light in the primary other valvular heart disease after surgical intervention, after a period of recovery, the right ventricular pressure decreased right ventricular narrowing, the regurgitation degree mostly reduced, or even disappear.
But some severe rheumatic heart disease patients, postoperative days three tricuspid valve regurgitation flow caused by the disorder of hemodynamics to low cardiac output, and one of the factors leading to operative death.
There are some patients with pulmonary hypertension is not expected to result in long-term postoperative right heart failure.
Therefore, in recent years, more than three degrees of tricuspid valve regurgitation is not complete, after the completion of other valve surgery, the implementation of the same period of three tricuspid valve ring plasty, in order to obtain satisfactory results.
Organic three tricuspid insufficiency, generally require surgical treatment. In light, first open open fusion junction, then annuloplasty; jiaochongzhe lesions, should be performed, valve replacement.
Three commonly used methods of tricuspid valve plasty are of three kinds
The annuloplasty, along the front flap and the flap at the junction and ring valve head with 1 to 2 non traumatic suture needle mattress suture, on both sides of cushion, knot shortening valve ring.
The De Vega operation, with no trauma before and after flap suture along the valve ring double cross continuous suture needle, needle at the ends of import each with a gasket, tightening suture knot, to shorten the expansion after the flap and the flap base valve ring.
Carpentier ring fixation, Carpentier ring is modeled on the shape of the three cusp ring, made of Stainless Steel Oval semi circle, wrapped in polyester cloth, there are different numbers. When the operation along the three tricuspid annulus placed mattress suture, suitable for sewing number
Carpentier ring. After the fixation, the expanded anterior and posterior flap can be reduced, so that the three cusps can be restored. The improved Carpentier ring is made of elastic material, which can adapt to the activity of the cardiac cycle and reduce the stress on the suture ring, thereby reducing the possibility of tearing.
