We report our experience with the use of a standard left Amplatz coronary catheter and a guidewire to cross the aortic valve in 34 patients being evaluated for valvular aortic stenosis. A number of 2 Amplatz left coronary catheter inserted via the femoral artery was positioned above the noncoronary aortic valve cusp with the tip aligned toward the aortic valve. This catheter allowed a soft-tipped, Teflon-coated guidewire to be guided through the aortic valve orifice. The catheter was then advanced over the guidewire into the left ventricle. This technique was successful within six minutes in 32 of 34 patients (94%). The stenotic aortic valve was crossed in less than two minutes in 15 patients (42%) and in less than four minutes in 31 (91%). The aortic valve was not crossed in two patients. Twenty-one patients (62%) had an aortic valve area of less than 0.75 cm2. There were no complications. We conclude that this technique provides a method for safe, rapid transaortic left ventricular catheterization in patients with aortic stenosis of all degrees of severity.
我们报告了在对34例接受主动脉瓣狭窄评估的患者中，使用标准左安普拉斯冠状动脉导管和导丝穿过主动脉瓣的经验。通过股动脉插入2号安普拉斯左冠状动脉导管，将其置于无冠状动脉主动脉瓣叶上方，尖端对准主动脉瓣。该导管允许一根软头、涂有特氟龙的导丝穿过主动脉瓣口。然后将导管沿导丝推进至左心室。该技术在34例患者中的32例（94%）在6分钟内成功。15例患者（42%）在不到2分钟内穿过狭窄的主动脉瓣，31例（91%）在不到4分钟内穿过。2例患者未穿过主动脉瓣。21例患者（62%）的主动脉瓣面积小于0.75平方厘米。无并发症发生。我们得出结论，该技术为所有严重程度的主动脉狭窄患者提供了一种安全、快速的经主动脉左心室插管方法。
