Adjunctive imaging modalities, including computerized tomography, intravascular ultrasound, and optical coherence tomography, facilitate higher success rates in chronic total occlusion interventions.
Adjunctive imaging modalities such as CT, IVUS, and OCT play a crucial role in improving the success rates of chronic total occlusion percutaneous coronary interventions.

May support adjunctive imaging in CTO PCI; leaves open need for randomized confirmation.
Chronic total occlusion percutaneous intervention is becoming a more common technique with higher success rates. These success rates can be at least partially attributed to the use of classical and contemporary imaging modalities. Preprocedural preparation including patient selection and detailed coronary imaging with the use of computerized tomography are helpful to ensure the highest chance of success. Procedural utilization of intravascular ultrasound and optical coherence tomography are additional tools to help facilitate success during difficult cases. Minimally invasive imaging modalities help determine improvement of left ventricular function or the presence of continued ischemia in the postprocedural period. Newer techniques including high-definition computerized tomography scanners can accurately show details of stent morphology and the presence of in-stent restenosis without the need of a further procedure. Invasive imaging including the use of intravascular ultrasound and optical coherence tomo...

Sapontis et al. (2013) conducted a review in Chronic total occlusions. Adjunctive imaging (CT, IVUS, OCT) was evaluated. Adjunctive imaging modalities, including computerized tomography, intravascular ultrasound, and optical coherence tomography, facilitate higher success rates in chronic total occlusion interventions.
