It is reported on the properties of the new catheter-tip pressure transducer IBW-79 (Ch 5) for applications in the left heart. The approach to the left ventricle was carried out with the help of Seldinger-technique (Ch 10) via A. femoralis. In all cases positioning of the pressure transducer in the left ventricle succeeded, but in 2 out of 12 patients there were complications after diagnostic program caused by the puncture. The pressure measurements were from a high quality and high fidelity. Zero shifts during the measurements were in the order of -0.5 kPa (-3.8 mm Hg), directions are given for correction or compensation. In our opinion the IBW-79 is a valuable new sensor-catheter for measuring the pressure in the left heart, above all for scientific applications.
本文报道了新型导管尖端压力传感器IBW - 79（第5章）用于左心的特性。借助Seldinger技术（第10章）经股动脉进入左心室。在所有病例中，压力传感器在左心室的定位均成功，但12例患者中有2例在诊断程序后因穿刺出现并发症。压力测量具有高质量和高保真度。测量期间的零点偏移约为 - 0.5 kPa（-3.8 mmHg），给出了校正或补偿的方向。我们认为，IBW - 79是一种用于测量左心压力的有价值的新型传感器导管，尤其适用于科学应用。
