Cardiac catheterization techniques for measuring the systolic pressure gradient across the stent-mounted porcine xenograft in the aortic position and accomplishing left ventriculography are described. The transseptal technique is a rapid and predictable means of entering the left ventricle but requires a highly skilled operator. Retrograde left ventricular catheterization via the femoral artery is a technique familiar to all invasive cardiologists. Usually a pitfall catheter is used. In patients with the stent-mounted procine xenograft in the aortic position, we have found the A2 Multipurpose catheter to be the fastest and most predictable means of entering the left ventricle from the groin. Potential complications of retrograde left ventricular catheterization in patients with aortic valve prostheses are discussed.
描述了用于测量主动脉位置支架植入猪异种移植物上的收缩压梯度并完成左心室造影的心脏导管插入技术。经间隔技术是进入左心室的一种快速且可预测的方法，但需要技术高超的操作人员。经股动脉逆行左心室导管插入术是所有介入心脏病学家都熟悉的技术。通常使用圈套导管。在主动脉位置植入支架猪异种移植物的患者中，我们发现A2多用途导管是从腹股沟进入左心室的最快且最可预测的方法。讨论了主动脉瓣假体患者逆行左心室导管插入术的潜在并发症。
