Key result
Cutting balloons restore antegrade flow during CTO PCI by expressing compressive subintimal hematomas.
Why the study?
Dissection and reentry techniques during CTO PCI can cause compressive hematomas that are suboptimally treated by balloon angioplasty or stenting and may extend hematomas distally.
Case Report
The use of a cutting balloon represents a novel technique to express compressive subintimal hematomas and restore antegrade coronary blood flow during CTO interventions.
Contemporary chronic total occlusion (CTO) percutaneous coronary interventional (PCI) techniques are increasingly dependent upon dissection and reentry techniques (DARTs) especially for long occluded lesions. DARTs can result in compressive hematomas during CTO interventions and traditional treatment with balloon angioplasty and/or coronary stenting are often suboptimal and may extend the hematoma distally. We describe the novel use of a cutting balloon to "express" these compressive hematomas and restore antegrade coronary blood flow.

Vo et al. (2017) conducted a case report in Chronic total occlusion (CTO) with subintimal hematomas during PCI. Cutting balloon was evaluated. A cutting balloon can be used to express compressive subintimal hematomas and restore antegrade coronary blood flow during chronic total occlusion percutaneous coronary interventions.
