Summary
With intracoronary imaging (intravascular ultrasound and optical coherence tomography), peri-procedural success for treating calcified lesions has increased significantly.
Usefulness & Problems
Why this is useful
OCT is an intracoronary imaging modality used during PCI to assess calcified coronary lesions. The abstract states that intracoronary imaging including OCT has increased peri-procedural success.; intracoronary imaging during PCI for calcified lesions; improving peri-procedural success in treatment of calcified coronary lesions; OCT is included conservatively as a named intravascular imaging modality because the abstract explicitly discusses diagnostic imaging modalities and the supplied web research summary identifies OCT as central to lesion assessment and stent-expansion evaluation in this topic area.; diagnostic imaging of calcified coronary lesions; lesion assessment during PCI planning and optimization

Published Workflows
Objective: Optimize procedural outcomes in calcified coronary lesions during percutaneous coronary intervention.
Why it works: The review abstract links poor outcomes in severe calcification to inadequate lesion preparation and suboptimal stent expansion, and then emphasizes imaging-guided assessment plus plaque modification to optimize outcomes.

Stages
- 1.Advanced imaging-based lesion assessment(functional_characterization)
The abstract emphasizes advanced imaging for precise lesion assessment and improved patient selection.
Selection: precise lesion assessment
- 2.Plaque modification strategy selection and lesion preparation(selection)
Severe calcification creates challenging lesion preparation and contributes to suboptimal stent expansion, so plaque modification is used to optimize procedural outcomes.
Selection: choice among atherectomy, specialized balloon technologies, or intravascular lithotripsy based on lesion needs
- 3.Combination strategy use in complex cases(decision_gate)
The abstract specifically highlights the use of combination strategies in complex cases.
Selection: complex case status after assessment and initial strategy planning
Objective: Optimize treatment of calcified coronary lesions during PCI by using intracoronary imaging and selecting among calcium-modification modalities according to lesion phenotype and current guidance.
Why it works: The abstract states that intracoronary imaging has increased peri-procedural success and that multiple calcium-modification modalities are used to address different phenotypes of calcified lesions.

Stages
- 1.Intracoronary imaging assessment(functional_characterization)
The abstract states that intracoronary imaging has significantly increased peri-procedural success for treating calcified lesions.
Selection: Assessment of calcified lesion features and phenotypes using IVUS or OCT
- 2.Calcium modification modality selection and lesion preparation(functional_characterization)
Calcified lesions increase procedural difficulty and complication risk, and the review discusses multiple calcium-modification techniques for different lesion phenotypes.
Selection: Choose among balloon escalation, intravascular lithotripsy, orbital atherectomy, and rotational atherectomy based on lesion phenotype and current recommendations or expert consensus.

The review covers balloon escalation, intravascular lithotripsy, orbital atherectomy, and rotational atherectomy as calcium-modification techniques and discusses their mechanisms, strengths, and limitations.
We will also focus on calcium modification techniques and their mechanisms: (1) Balloon escalation technique, (2) intravascular lithotripsy, (3) orbital atherectomy, and (4) rotational atherectomy. We will focus on the strengths and limitations of each technique, based on current recommendations and expert consensus from SCAI.
