Special Issue Information

Dear Colleagues,

Coronary artery disease is the leading cause of death worldwide. Intracoronary imaging and coronary physiology techniques allow for a tailored diagnosis (distinguishing between fixed coronary stenosis, vasospasm, microcirculatory dysfunction, coronary dissection, and plaque rupture and erosion). Furthermore, percutaneous coronary intervention (PCI), the most widely used myocardial revascularization technique, has undergone numerous advances thanks to the introduction of intracoronary imaging, drug-coated balloons, and bioresorbable scaffolds (BRSs). Moreover, coronary bifurcations represent a challenge for the interventional cardiologist and are associated with a higher failure rate.

This topic will cover the following important aspects of coronary artery disease diagnosis and treatment:

  • Treatment of coronary bifurcation lesions;
  • Intracoronary imaging (intravascular ultrasound (IVUS); optical coherence tomography (OCT));
  • Coronary physiology techniques;
  • Drug-coated balloons;
  • Bioresorbable scaffold (BRS).

Research articles, review articles, and communications are invited.

Objective: Kawasaki disease (KD) is characterized as an acute systemic vasculitis predominantly affecting young children, with coronary artery lesions (CALs) representing the most serious complication. Therapeutic resistance to intravenous immunoglobulin (IVIG) remains a significant clinical challenge. Consequently, numerous investigations have sought to identify predictive risk factors for IVIG resistance (IVIGR) and CAL development. Limited research has systematically evaluated the prognostic utility of electrocardiographic (ECG) parameters in KD outcome prediction. This study was therefore undertaken to assess the contributory value of ECG analysis in determining KD prognosis and therapeutic responses. Methods: This prospective cohort study enrolled 255 hospitalized children diagnosed with KD at West China Second University Hospital between July 2022 and December 2024. Initially, univariate analysis was performed to identify risk factors differentiating IVIGR from non-IVIGR patients and CAL from non-CAL patients. Statistically significant parameters were subsequently incorporated into machine learning analyses. Random forest algorithms were employed to construct predictive models based on the following: (1) complete blood count parameters, (2) biochemical and metabolic profiles, (3) electrocardiographic features, and (4) a comprehensive multimodal model integrating all parameters. These models generated feature importance scores, providing hierarchical rankings that quantified the relative contribution of each predictor to outcome prediction. Results: Univariate analysis demonstrated that alterations in hematological parameters, biochemical and metabolic profiles, and electrocardiographic features were significantly associated with therapeutic responses to IVIG and CAL development. Machine learning analysis revealed that ECG parameters individually contributed modest predictive weight for KD prognosis. However, the integration of ECG features into the comprehensive model substantially enhanced the discriminatory capacity, elevating the area under the curve (AUC) to 0.92 for CAL prediction. For IVIGR prediction, ECG-exclusive models demonstrated suboptimal performance in early disease management. Nevertheless, the multimodal integration of ECG with inflammatory and metabolic biomarkers achieved a comparable AUC of 0.92 for IVIGR prediction. Conclusions: This study establishes that ECG parameter alterations are significantly associated with CAL development and IVIGR in KD patients. Although ECG features demonstrate a limited independent predictive capacity compared to inflammatory and metabolic biomarkers, their integration into comprehensive predictive models substantially enhances discriminatory performance. These findings underscore the complementary value of electrocardiographic assessment in multimodal risk stratification strategies for KD management, supporting the clinical utility of ECG analysis as an adjunctive prognostic tool when combined with conventional laboratory parameters.

Background: Carotid contrast-enhanced ultrasound (CEUS) provides a noninvasive means of assessing plaque vulnerability and may reflect the systemic burden of atherosclerosis. This study aimed to evaluate the diagnostic performance of carotid CEUS characteristics for identifying functionally significant coronary artery stenosis (CAS) defined by quantitative flow ratio (QFR). Methods: In this preliminary prospective study, 46 patients with suspected stable coronary artery disease who underwent carotid CEUS and coronary angiography with QFR assessment between September 2022 and November 2023 were enrolled. Patients were categorized into a QFR ≥ 0.80 group (n = 18) and a QFR < 0.80 group (n = 28). Carotid plaque burden, morphology, and CEUS-derived quantitative parameters were compared between groups. Univariate and multivariable logistic regression analyses were performed to identify independent factors associated with QFR < 0.80, and receiver operating characteristic (ROC) analysis was used to assess discriminatory performance. Results: Compared with patients with QFR ≥ 0.80, those with QFR < 0.80 had significantly higher mean intima-media thickness (IMT), larger plaque area, higher plaque-to-lumen enhancement ratios (Pmax/Cmax and Pmean/Cmean), and more vulnerable plaque features, including irregular margins and thin fibrous caps. In multivariable analysis, Pmax/Cmax (adjusted OR: 14.394, 95% CI: 2.718–76.220; p = 0.002) and mean IMT (adjusted OR: 7.740, 95% CI: 2.040–29.363; p = 0.003) remained independently associated with QFR < 0.80. ROC analysis showed that the combined model incorporating Pmax/Cmax and mean IMT achieved the best discrimination for QFR < 0.80 (AUC: 0.931, 95% CI: 0.845–0.989), with 78.6% sensitivity and 94.4% specificity. Conclusions: Carotid CEUS-derived plaque enhancement characteristics, particularly Pmax/Cmax, together with mean IMT, were independently associated with functionally significant CAS. These findings suggest that carotid CEUS may provide complementary, noninvasive information for vascular risk stratification, but it should not be considered a substitute for coronary angiography-based physiological assessment.

Coronary bifurcation lesions are considered among the most challenging lesions to treat with percutaneous coronary intervention (PCI), particularly in cases of extensively diseased branches. In the event of failure of a provisional (one-stent) approach, many two-stent bifurcation techniques can be performed for the treatment of coronary bifurcation lesions. Two techniques (culotte and T/TAP) are suggested by the European Bifurcation Club, but a reverse crush is performed by some operators. This study aims to retrospectively compare these two different approaches (EBC-recommended techniques vs. reverse crush). Full article

Performance of percutaneous coronary intervention (PCI) for bifurcation lesions involves complex decision-making informed by anatomic, hemodynamic, technical, and clinical factors. Building on the procedural foundations discussed in the companion paper in this two-part series, this second paper focuses on advanced considerations in bifurcation PCI. Factors associated with side branch (SB) compromise are discussed, including bifurcation angle and distribution of plaque location, along with strategies for SB protection and SB rewiring. Outcomes of landmark randomized controlled trials of provisional versus two-stent approaches, as well as specific two-stent techniques, are summarized. Based on these factors, an algorithmic approach for bifurcation PCI is outlined. Lastly, the use of drug-coated balloons, dedicated bifurcation stents, bioresorbable vascular scaffolds, bioadaptor stents, physiologic testing, intravascular imaging, and other emerging innovations are explored to provide a perspective on the future of bifurcation PCI.

Percutaneous coronary intervention (PCI) of bifurcation lesions remain one of the most technically challenging areas in interventional cardiology. Careful planning and execution are needed to preserve main vessel and side branch patency, with evolving evidence guiding the choice between provisional and two-stent strategies, and between individual techniques. This narrative review, which represents the first installment of a two-part series, synthesizes current knowledge on bifurcation PCI, detailing the anatomical classifications, lesion assessment tools, procedural planning, and execution of techniques including T and Protrusion (TAP), double-kissing (DK) crush, mini-crush, culotte, V-stent, and emerging modifications. We contextualize the choice of strategy within lesion complexity, procedural goals, and patient-specific considerations. This review is intended as a visual, practical, technique-focused reference for interventionalists and interventional trainees involved in the management of bifurcation lesions. Full article

Coronary CT angiography (CCTA) has seen steady progress since its inception, becoming a key player in the non-invasive assessment of coronary artery disease (CAD). Advancements in CT technology, including iterative and deep-learning-based reconstruction, wide-area detectors, and dual-source systems, have helped mitigate early limitations, such as high radiation doses, motion artifacts, high iodine load, and non-diagnostic image quality. However, the adjustments between ionizing radiation and iodinated contrast material (CM) volumes remain a critical concern, especially due to the increasing use of CCTA in various indications. This review explores the balance between radiation and CM volumes, emphasizing patient-specific protocol optimization to improve diagnostic accuracy while minimizing risks. Radiation dose reduction strategies, such as low tube voltage protocols, prospective ECG-gating, and modern reconstruction algorithms, have significantly decreased radiation exposure, with some studies achieving sub-millisievert doses. Similarly, CM volume optimization, including adjustments in strategies for calculating CM volume, iodine concentration, and flow protocols, plays a role in managing risks such as contrast-associated acute kidney injury, particularly in patients with renal impairment. Emerging technologies, such as photon-counting CT and deep-learning reconstruction, promise further improvements in dose efficiency and image quality. This review summarizes current evidence, highlights the benefits and limitations of dose control approaches, and provides practical recommendations for practitioners. By tailoring protocols to patient characteristics, such as age, renal function, and body habitus, clinicians can achieve an optimal trade-off between diagnostic accuracy and patient safety, ensuring optimal operation of CT systems in clinical practice.
