Our improvement on Turner's technique enabled more accurate plain x-ray estimation of pulmonary venous pressure (PVP) up to 60 mm and of systolic pulmonary arterial pressure (PAP) up to 150 mm in 215 patients catheterized for mitral valvular disease. Our improvement comprises (1) five main pulmonary artery (MPA) grades 0 to IV according to its area and volume; (2) modified pressure values assigned for MPA and kinetic energy of the right ventricle (required to pump blood into the pulmonary arterial bed) according to MPA grades; and (3) nine PVP grades from 0 to 8 with corresponding assigned PVP values. These modifications have enhanced the accuracy of the technique up to 85 to 95%.
我们对特纳技术的改进，使215例因二尖瓣疾病接受心导管检查的患者，能够更准确地通过普通X线评估肺静脉压（PVP），最高可达60毫米汞柱，以及收缩期肺动脉压（PAP），最高可达150毫米汞柱。我们的改进包括：（1）根据主肺动脉（MPA）的面积和容积，将其分为0至IV级五个主要等级；（2）根据MPA等级，为MPA和右心室（将血液泵入肺动脉床所需）的动能分配修正压力值；（3）从0到8分为九个PVP等级，并分配相应的PVP值。这些改进使该技术的准确性提高到了85%至95%。
