The tip of a radiofrequency (RF) needle is positioned under both intravascular ultrasound (IVUS) guidance and biplane fluoroscopic guidance A: IVUS imaging confirms adequate tenting position with the RF needle B: Illustration of tenting position with the RF needle C: Angiogram shows dilatation of the created re-entry tear using a balloon catheter D.
