Title: One 6-f guiding catheter and one microcatheter to accomplish a retrograde chronic total occlusion approach: The “reverse tip-in” or “introspect” technique


The retrograde approach has significantly increased the overall success rate of chronic total occlusion (CTO) percutaneous coronary intervention (PCI), up to 90% in the hands of experienced CTO operators. The “tip-in” technique involves inserting an antegrade microcatheter over the retrograde guidewire, allowing for antegrade intervention on the CTO segment. Through the presentation of the following case, we want to illustrate how to undertake a retrograde approach to bridge the occluded segment via the “reverse tip-in” or “introspect” technique, using a single guiding catheter with one microcatheter inside.


Ehsan Khalilipur graduated from Rajaie cardiovascular medical and research center in cardiology and cardiovascular intervention and as a tertiary center, I had the honor to be an attending of interventional cardiology from a year ago in this center and since my fellowship, I published over 30 manuscript and two books with some being remarkable as a new technique in this field.
