OCT images identified plaque rupture (PR), classifying lesions into PR and intact fibrous cap (IFC) groups. The IFC group was further divided based on the presence of lipid-rich plaque (LRP), defined as a plaque with a maximum lipid angle > 90°. This study included 370 ACS patients (mean age 65.2 ± 12.3 years, 82.4% male). Angiographic evidence of MB was present in 8.6% (32/370) of patients prior to PCI and increased to 17.0% (63/370) post-PCI; all MBs identified pre-PCI were also observed post-PCI. OCT identified 213 lesions with plaque rupture and 157 lesions with IFC (of which 83 exhibited underlying LRP and 74 did not). The prevalence of post-PCI angiographically detected MB differed significantly among the OCT-defined morphological groups: 11.3% (24/213) in the PR group, 18.1% (15/83) in the IFC-LRP group, and 32.4% (24/74) in the IFC-non-LRP group (P < 0.01).

Although PVL has been reported to gradually decrease after self-expandable valves (SEVs) implantation, the mechanism remains unclear. Furthermore, while gradual expansion of SEVs has been documented, studies assessing their morphological changes during the chronic phase are lacking. This study aims to evaluate whether SEVs expansion occurs during follow-up and if this expansion correlates with a reduction in PVL. We included 60 patients who underwent TAVI using SEVs (Evolut PRO/PRO+/FX) from October 2020 to August 2024. Morphological findings of SEVs were assessed using computed tomography (CT), and PVL was evaluated at discharge and chronic phase post-TAVI. PVL was graded on a five-point scale via transthoracic echocardiography, and the area ratio, defined as the ratio of the basal area of the implanted SEVs to that of phantom valves measured by CT, served as the index of SEVs expansion. Chronic expansion of SEVs was observed in all cases, with the area ratio increasing from 0.59 at discharge to 0.64 at the follow-up (P < 0.05). Among the 60 patients, 44 exhibited mild or greater PVL, with 17 showing improvement at the chronic phase. The degree of valve expansion (area ratio at chronic phase/area ratio at discharge) was significantly greater in the PVL improvement group compared to the non-improvement group (1.11 vs. 1.06, P < 0.05).

The Dual-Prep registry is a multicenter, prospective registry of consecutive image-guided percutaneous coronary interventions (PCI). The primary effectiveness and safety endpoints were procedural success (residual stenosis < 50% by quantitative coronary angiography) without an in-hospital major adverse cardiac event (MACE) and 30-day freedom from MACE, respectively. Baseline vessel calcification score and final DES expansion were evaluated by optical coherence tomography (OCT). A total of 118 patients with 120 lesions were enrolled at 20 sites. The calcification score of lesions after atherectomy by core-lab assessment was 4.0 in all cases. Rotational atherectomy was applied prior to IVL in 83.9% cases with mean burr size of 1.57 ± 0.20 mm; IVL was subsequently successfully delivered in all cases (mean balloon diameter 3.02 ± 0.45 mm), followed by DES deployment (mean diameter 3.19 ± 0.51 mm, length of 36.3 ± 16.0 mm).
