Reconstruction of the right ventricular outflow tract at the time of total correction of tetralogy of Fallot, the pulmonary valve annulus has been sized with fingers and Hegar dilators at our institute. But it has not always been sized correctly. To preclude such a problem, we designed new annulus sizers which have two cylindrical parts and a flexible handle (100 mm). The cylindrical parts are 40 mm in length, 8 to 30 mm in diameter, and have three lines marked every 10 mm from the end. Adjustment of the line to the valve annulus allows for correct measurement of the size. Moreover, we consider these sizers to be beneficial for annuloplasty of the atrioventricular valve, measurement of the mitral valve area after commissurotomy and the inner diameter of arteries.
在法洛四联症完全矫正时重建右心室流出道，在我们研究所，肺动脉瓣环一直是用手指和黑加扩张器测量大小的。但并不总是能准确测量。为避免此类问题，我们设计了新型瓣环测量器，它有两个圆柱形部分和一个柔性手柄（100毫米）。圆柱形部分长40毫米，直径8至30毫米，从末端起每隔10毫米有三条标记线。将标记线与瓣膜环对齐可准确测量大小。此外，我们认为这些测量器对房室瓣瓣环成形术、二尖瓣交界切开术后二尖瓣面积的测量以及动脉内径的测量有益。
