Introduction: Inability to cross CTO with first balloon after successful wiring. Prevalence: 6.4% to 10% (Operator experience) No specific clinical and angiographic predictors. ? Heavy calcium. WCC & IVUS 2015
Techniques Techniques increasing guide catheter support: Long sheaths (35 cms) 8F extra support guide, eg: EBU, XB,AL. Deep throttling Guideliner (mother and child technique) Anchor Balloons Hydrophilic embodiment of the wires. WCC & IVUS 2015
Contd.., Techniques modifying the CTO lesion: Grenadoplasty Wedgies (Balloon Assisted Micro Dissections) low profile Hydrophylic balloons Micro catheter advancing Recrossing with 2 nd wire wire cutting technique seasaw Balloon wire cutting subintimal distal anchor wire subintimal space plaque modification – Antegrade knuckle, stringray balloon WCC & IVUS 2015
Contd.., Retrograde approach – Distal anchor by retrograde balloon, reverse CART, retrograde knuckle(hybrid approach) Rotational atherectomy X 80 Excimer Laser ( Ablative and Acoustic energy) WCC & IVUS 2015
