Article Abstract
Introduction: The guiding catheter lock technique is a therapeutic technique to increase backup force of the guiding catheter in coronary artery interventions.
Surgical Technique: A 71 year old man presented with rapidly declining kidney function resulting from bilateral renal artery stenosis. During the renal artery stenting procedure, the 0.014" guidewire became trapped at the stent's distal edge. Although attempts were made to advance a microcatheter and balloon catheter over the trapped guidewire, these failed because of insufficient pushability of the guiding catheter. Therefore, the guiding catheter lock technique was used with a second guiding catheter, and the guidewire was successfully retrieved.
Discussion: The guiding catheter lock technique facilitated strong pushability to allow for successful retrieval of a stuck guidewire during renal artery stenting.

Background: Umbilical arterial catheterisation is a common intervention performed in the neonatal intensive care unit (NICU) especially in extremely preterm and extremely low birth weight neonates. Rarely catheter fracture or breakage can occur, leaving behind part of the catheter in the aorta. A handful of cases have been reported in the literature, with the majority being managed surgically.

Purpose: There is limited evidence to guide the use of enteral nutrition (EN) for children with bronchiolitis who received Humidified high flow nasal cannula (HHFNC) and often kept nil per mouth for aspiration and progression to mechanical ventilation risk.
Methods: This quality improvement project included children with bronchiolitis who were supported by HHFNC in the paediatric intensive care unit (PICU). An algorithm to increase EN use in those participants was created by stakeholders.

Background: Invasive coronary physiology including fractional flow reserve (FFR), instantaneous wave-free ratio (iFR), and coronary flow reserve (CFR) are guideline-endorsed tools to guide the management of coronary artery disease (CAD). Complex factors impact and confound these assessments, and discordance between modalities complicates clinical management. iEquate is a prospective observational trial that combines multi-modality coronary physiology and optical coherence tomography (OCT) to identify the determinants of pressure-wire derived myocardial ischemia and iFR-FFR discordance.

Background: Despite successful mechanical thrombectomy (MT), approximately 50% of patients with large vessel occlusion (LVO) stroke experience poor outcomes due to reperfusion injury. Intra-arterial infusion of human serum albumin (HSA) may offer neuroprotective benefits; however, its safety and feasibility have not been established when delivered via the internal carotid artery. In this study we aimed to evaluate the safety and technical feasibility of HSA infusion through the guiding catheter placed during MT in patients with anterior circulation LVO stroke following successful reperfusion.
