Key result

Retrograde PCI for chronic total occlusion achieved an overall procedural success rate of 84.8%, and increased use of channel dilators in 2010 did not significantly improve success (85.3% vs 84.1%, P=0.63).

Overview

Retrograde CTO PCI success stable despite channel dilators; leaves open whether calcification mitigation can improve outcomes in prospective studies.

Type

Observational (n=801)

Multicenter

Yes

Structured PICO

Population
801 patients who underwent retrograde PCI for chronic total occlusion across 28 Japanese centers between 2009 and 2010.
E
Exposure
Retrograde percutaneous coronary intervention (PCI) for chronic total occlusion (CTO)
O
Outcome
Overall procedural and clinical success rates

Increased use of channel dilators in retrograde PCI for CTO reduces procedure time but does not significantly increase overall procedural success, which remains hindered by severe calcification.

Cite This Study

Tsuchikane et al. (2013) conducted an observational in chronic coronary total occlusion (n=801). Retrograde percutaneous coronary intervention (PCI) was evaluated on Overall procedural success rate. Retrograde PCI for chronic total occlusion achieved an overall procedural success rate of 84.8%, and increased use of channel dilators in 2010 did not significantly improve success (85.3% vs 84.1%, P=0.63).
