We report our experience with the use of a USCI Sones catheter curve A type 1 (7540) to cross the aortic valves of 45 patients with clinically significant aortic stenosis. The technique was successful in all our patients with a fluoroscopic time of less than 3 min. A gradient of up to 200 mmHg across the aortic valve area was recorded, and the smallest valve area calculated was less than 0.2 cm2. The method obviated the need for a guidewire and satisfactory left ventriculograms were obtained. No major complication was observed. We conclude that the technique is a simple, rapid, and safe means of obtaining left ventricular hemodynamic and angiographic information in patients with aortic stenosis of various degrees of severity.
我们报告了使用美国心血管介入（USCI）索恩斯导管曲线A 1型（7540）穿过45例具有临床显著主动脉瓣狭窄患者的主动脉瓣的经验。该技术在我们所有患者中均成功，透视时间少于3分钟。记录到跨主动脉瓣区域的压力梯度高达200 mmHg，计算出的最小瓣口面积小于0.2平方厘米。该方法无需导丝，并获得了满意的左心室造影图像。未观察到重大并发症。我们得出结论，该技术是一种在不同严重程度的主动脉瓣狭窄患者中获取左心室血流动力学和血管造影信息的简单、快速且安全的方法。
