We present the case of a 67-year-old male with an initial presentation of inferior STEMI and 2:1 Mobitz Type II AV block, who underwent successful primary percutaneous coronary intervention (PPCI) for a thrombotic occlusion in the right coronary artery (RCA) then staged procedure for calcium modification and stenting. This report highlights two key aspects of the procedure: using saline instead of contrast for optical coherence tomography (OCT) to minimize contrast exposure, and and employing combination of orbital atherectomy followed by intravascular lithotripsy (IVL) for calcium modification in a heavily calcified lesion. The case underscores the importance of individualized procedural strategies to optimize outcomes in patients with complex coronary anatomy and comorbid CKD. In conclusion, using saline-enhanced OCT provides adequate imaging and helps to minimize contrast use to prevent kidney injury while the combined use of orbital atherectomy and IVL allowed for optimal calcium modification, enabling excellent stent deployment in a severely calcified coronary disease.</p>\u0000 </div>","PeriodicalId":9650,"journal":{"name":"Catheterization and Cardiovascular Interventions","volume":"105 5","pages":"1183-1187"},"PeriodicalIF":2.1,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143122323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In acute coronary syndromes, it helps to detect culprit lesions that are not clearly visible on angiography and plays a key role in the diagnostic algorithm for myocardial infarction with non-obstructive coronary arteries (MINOCA).

Each stent was serially dilated in 1 mm increments under fluoroscopy using three techniques: 2 cm length, semi-compliant balloons (Technique 1), 2 cm, noncompliant balloons straddling the entire stent (Technique 2), or noncompliant balloons in an “inside-out” manner (balloon shorter than stent or 2 cm balloon aligned with distal end of stent (no straddle); (Technique 3). Technique 1 crossed over to noncompliant balloons once stent “napkin-ringed” (NR).

Technique 2 caused less SS (median 14%, IQR 7, 15), and Technique 3 caused the least SS (median 7%, IQR 3, 11). ISF was achieved in all, however, the inside–out technique caused ISF at smaller stent diameters (median 114% recommended postdilation limit vs. 122%–131%) and lower inflation pressures (median 15 vs. 28–29 ATM). ISF was achieved in Technique 1 after napkin ringing but required larger noncompliant balloons than other techniques (median 8.5 vs. 7 mm).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>Inside–out dilation resulted in less SS and fracture at smaller diameters with lower inflation pressures.
