Case1-RCA CTO Crossed, balloon doesn't cross, crossed with Rota wire then rota done done and DES deployed good final result.Case2-LAD CTO ballloon doesn't croos then Crossed with Corsair & Rota done, DES deployed good final result.Case3-RCA CTO Balloon doesn't crossed crossed using anchor Balloon technique, DES deployed good final result. Case4- RCA CTO Wire didn't crossing so Crossed by using Anchor Wire, DES deployed good final result. Case5- RCA CTO Crossing by BAM( Balloon Assisted Microdissection) DES deployed Good final result.Case6- RCA CTO Antegrade crossing with Retrograde Landmark, DES deployed good final result. Case7- LCX CTO Wire Knuckled crossed and entered true lumen with Star Technique, DES deployed good final result. Case8- CTO Abnormal RCA with Guidezilla Support antegradely Capture Technique DES deployed good final result.

In case of uncrossable Balloon after passage of wire into true lumen the working wire can be replaced by rota wire and Rota can be done to assist passage of balloonIf Rota-wire doesn't cross stiff microcatheter like Corsair can be helpful in making the passage. Tornus can be helpful under such situations. If after wire crossing if balloon doesn’t cross Anchor Balloon Technique can be useful in CTO crossing.Even the anchor wire gives the support, the support can be increased by inflating the balloon in side branch.In uncrossable proximal lesion BAM technique is effective.
