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.

The guide extension-facilitated ostial stenting (GEST) technique uses a guide extension catheter (GEC) to improve stent delivery during primary coronary angioplasty (PCI). GECs are used for stent delivery into the coronary arteries of patients with difficult anatomy due to tortuosity, calcification, or chronic total occlusion (CTO) vessels. Stent and balloon placement has become challenging in patients with increasing lesion complexity due to tortuosity, vessel morphology, length of the lesion, and respiratory movements.

Transcatheter mitral valve replacement (TMVR) may emerge as a surgical alternative for high-risk patients with severe mitral annular calcification (MAC), yet several questions remain to be addressed. We present the case of a 67-year-old high-risk female patient with severe MAC (MAC score = 8) and mitral stenosis (effective orifice area = 121.3 mm).

Transarterial embolization (TAE) is an image-guided, minimally invasive procedure for treating various clinical conditions by delivering embolic agents to occlude diseased arteries. Conventional embolic agents focus on vessel occlusion but can cause unintended long-term inflammation and ischemia in healthy tissues. Next-generation embolic agents must exhibit biocompatibility, biodegradability, and effective drug delivery, yet some degradable microspheres degrade too quickly, leading to the potential migration of fragments into distal blood vessels causing off-target embolization.

The novel case report of a temporary arrhythmia that developed after a positional change in a patient under general anesthesia emphasizes the possibility of potentially lethal cardiac arrhythmias that may develop owing to caudal movement of the peripherally inserted central venous catheter ([CVC] PICC) tip when changing patient positions. We present a case of temporary arrhythmia that developed after a positional change in a 44-year-old female patient scheduled for laparoscopic adrenalectomy under general anesthesia. She had undergone preoperative insertion of a PICC using an electrocardiogram (ECG)-guided tip confirmation system (TCS).

Background: Heavily calcified coronary artery disease presents significant challenges in percutaneous coronary intervention (PCI), often requiring advanced techniques to achieve optimal outcomes. Cutting balloons (CB) have shown potential for plaque modification; however, their effectiveness is limited without standardized protocols.
Aims: This study introduces the RODIN-CUT technique, a novel approach utilizing sequential CB inflations with real-time intravascular ultrasound (IVUS) guidance.
