Endovascular thrombectomy is now the standard of care for large vessel occlusion stroke. The aim is to achieve rapid and complete recanalisation while avoiding complications. Apart from the conventional complications of neurointerventional procedures, mechanical thrombectomy has its unique set of complications, inherent to the disease pathophysiology. We describe an unusual complication of catheter fracture and subsequent distal embolisation into the cerebral vasculature, which was noticed 24 hours after the procedure. Due to a lack of clinical consequences, we decided to manage it conservatively. The patient died within the following few days from respiratory complications unrelated to the stroke or the endovascular thrombectomy procedure. Consequently, we were able to retrieve the fractured segment and carry out histopathological analysis, which helped us to identify exactly its origin from the guide catheter. We believe that systematic reporting and database compilation of such device-related complications will aid in the design and development of neurointerventional devices in the future.

Background: The rotational atherectomy system can effectively debulk calcified coronary lesions. However, rare complications specific to that system have been reported.
Case Summary: A 77-year-old man with a heavily calcified lesion in the right coronary artery (RCA) ostium underwent percutaneous coronary intervention in an 8-F system.

Background: Diabetic foot ulcers (DFU) are a prevalent complication of diabetes, leading to significant morbidity, mortality, and amputation rates. Chronic non-healing DFU often result from peripheral neuropathy, microvascular issues, and infection, with poor blood and oxygen supply being critical factors in delayed healing. The development of new treatments to promote blood supply and accelerate ulcer healing is a significant area of research for DFU management.

Background: Optical coherence tomography (OCT) with artificial intelligence (AI) has been developed.
Aims: The study aimed to evaluate the differences between AI-quantified and visual assessments.
Methods: Patients scheduled for OCT-guided percutaneous coronary intervention between September 2021 and October 2022 were included.

Introduction: Wave speed (WS) mapping, enabled by omnipolar technology, allows for real-time visualization of local conduction velocity (CV). Its utility in ventricular tachycardia (VT) ablation has not been fully characterized.
Methods And Results: We describe a case series of patients undergoing VT ablation in which WS mapping was applied alongside established techniques such as peak frequency (PF) mapping and isochronal late activation mapping (ILAM).

Traditionally, clinical devices are designed, tested and improved through lengthy and expensive laboratory experiments and clinical trials [1]. More recently, computational methods have allowed for rapid testing, speeding up the design process and enabling far more complete searches of design space. While computational models cannot fully capture the complexities of biological systems, they provide valuable insights into crucial underlying mechanisms, such as the effects of fluid-structure interactions (FSIs).
