In 19 consecutive children with aortic valve stenosis, the left ventricle was entered retrogradely with a Gensini catheter guided by a tip-deflector guidewire which could produce any desirable degree of curvature at its tip. In all patients, the aortic valve was retrogradely traversed for measurement of the pressure gradient (mean gradient = 53 mmHg, mean valve area = 0.36 cm2), and left ventriculography. No complications were encountered. This technique is safe, simple, and effective in retrograde catheterization of the left ventricle in children with aortic stenosis.
在19例连续性主动脉瓣狭窄患儿中，使用可在尖端产生任意所需弯曲度的尖端偏转导丝引导Gensini导管经逆行途径进入左心室。所有患者均经逆行途径穿过主动脉瓣以测量压力阶差（平均阶差=53 mmHg，平均瓣膜面积=0.36 cm²）并进行左心室造影。未发生并发症。该技术在主动脉狭窄患儿左心室逆行导管插入术中安全、简单且有效。
