Objectives The authors sought to describe the angiographic characteristics, strategy associated with perforation, and the management of perforation during chronic total occlusion percutaneous coronary intervention (CTO PCI).
Background The incidence of perforation is higher during CTO PCI compared with non-CTO PCI and is reportedly highest among retrograde procedures.
Methods Among 1,000 consecutive patients who underwent CTO PCI in a 12-center registry, 89 (8.9%) had core lab–adjudicated angiographic perforations. Clinical perforation was defined as any perforation requiring treatment. Major adverse cardiac events (MAE) were defined as in-hospital death, cardiac tamponade, and pericardial effusion.
Results Among the 89 perforations, 43 (48.3%) were clinically significant, and 46 (51.7%) were simply observed. MAE occurred in 25 (28.0%), and in-hospital death occurred in 9 (10.1%). Compared with nonclinical perforations, clinical perforations were larger in size, more often at a collateral location, had a high-risk shape, and less likely to cause staining or fast filling. Compared with perforations not associated with MAE, perforations associated with MAE were larger in size, more proximal or at collateral location, and had a high-risk shape. When the core lab attributed the perforation to the approach used when the perforation occurred, 61% of retrograde perforations by other classifications were actually antegrade.
Conclusions Larger size, proximal or collateral location, and high-risk shapes of a coronary perforation were associated with MAE. Six of 10 perforations occurred with antegrade approaches among patients who had both strategies attempted. These finding will help emerging CTO operators understand high-risk features of the perforation that require treatment and inform future comparisons of retrograde and antegrade complications.
