Article Abstract
Objective: This study aimed to compare the efficacy and safety of intravascular ultrasound (IVUS)-guided coronary intravascular lithotripsy and rotational atherectomy in treating severe coronary artery calcification.
Methods: A retrospective analysis of 60 patients who underwent percutaneous coronary intervention at the General Hospital of Ningxia Medical University from October 2022 to August 2023 was conducted. The patients were divided into two groups: 30 received IVUS-guided coronary intravascular lithotripsy and 30 underwent IVUS-guided rotational atherectomy. The primary endpoints comprised angiographic thrombolysis in myocardial infarction III flow and <30% stenosis post-percutaneous coronary intervention, and IVUS metrics, such as >80% stent expansion, avoiding high plaque burden or lipid-rich plaques, minimizing malapposition <0.4 mm/1 mm, and preventing tissue prolapse and dissection. Safety was assessed by complications and 1- and 6-month postoperative major adverse cardiovascular event rates.
Results: The primary endpoint was achieved in both groups. The treatment efficacy was 100% in all cases. At 1 and 6 months post-procedure, there was no significant difference in major adverse cardiovascular events, acute myocardial infarction, or stent thrombosis between the two groups.
Conclusion: IVUS-guided coronary intravascular lithotripsy is a safe and effective alternative to rotational atherectomy, potentially reducing certain complications.

Intravascular optical coherence tomography (OCT) has represented a revolutionary invasive imaging method, offering high-resolution cross-sectional views of human coronary arteries, thereby promoting a significant evolution in the understanding of vascular biology in both acute and chronic coronary pathologies. Since the development of OCT in the early 1990s, this technique has provided detailed insights into vascular biology, enabling a more thorough assessment of coronary artery disease (CAD) and the impact of percutaneous coronary intervention (PCI). Moreover, a series of recent clinical trials has consistently demonstrated the clinical benefits of intravascular imaging (IVI) and OCT-guided PCI, showing improved outcomes compared to angiography-guided procedures, particularly in cases of complex coronary pathology.

Myocardial infarction with non-obstructive coronary arteries (MINOCA) is a group of heterogeneous diseases with different pathological mechanisms. It is often under-recognized because of its diverse differential diagnoses like myocarditis, takotsubo cardiomyopathy, spontaneous coronary artery dissection (SCAD), coronary microvascular dysfunction, vasospasm, coronary erosion, and embolism. Evaluation with multimodality imaging including intravascular coronary imaging and cardiac magnetic resonance is often necessary to determine the underlying etiology and management.

Background: Pulsed electric field ablation (PFA) techniques for treating cardiac arrhythmias have attracted considerable interest. For example, atrial fibrillation can be effectively treated by pulmonary vein isolation using PFA. However, some arrhythmias originate deep within the myocardium, making them difficult to reach with conventional ablation methods.

Aims: Stent under-expansion is a well-known predictor of post-percutaneous coronary intervention (PCI) major adverse cardiovascular events (MACE). This article presents a new technique to image coronary stents in 3D in the cathlab utilizing only the angiographic equipment.
Methods And Results: Thirty patients with an indication of PCI were consented and prospectively included.

Background: An inward force is experienced by the guide catheter during device retrieval resulting in potential risk of deep engagement into the ostio-proximal coronary segment. This undesired movement can result in coronary injury. There is no systematic data or reports of techniques to prevent such inadvertent guide movement during difficult retrieval of devices.
