Clinical Significance of Optical Coherence Tomography–Guided Percutaneous Coronary Intervention for In‐Stent Restenosis Within Drug‐Eluting Stents: Impact on Patient Outcomes

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background The evidence for optical coherence tomography (OCT)–guided percutaneous coronary intervention (PCI) in improving the prognosis of individuals with in‐stent restenosis (ISR) is lacking.

Using Hydrogel Beads as a Blood Model in Optical Coherence Tomography

Current Directions in Biomedical Engineering, 2023
Optical Coherence Tomography (OCT) is a standard imaging procedure in ophthalmology. OCT Angiography is a promising extension, allowing for fast and non-invasive imaging of the retinal vasculature analyzing multiple OCT scans at the same place.

Outcomes of optical coherence tomography guided percutaneous coronary intervention against angiography guided in patients with coronary artery disease: A systematic reviews and meta-analyses

Indian Heart Journal, 2023
Background: Previous studies compared optical coherence tomography (OCT) guided percutaneous coronary intervention (PCI) and angiography-guided was still limited. Therefore, we performed comprehensive meta-analyses to investigate the clinical outcomes of

The Fibular Artery Communicating Branch and Fibular Artery Dominance: An Anatomical Hazard for Posterior Approaches to the Ankle

Clinical Anatomy, EarlyView.
ABSTRACT Open reduction of posterior malleolar fractures (PMFs) increasingly employs direct posterior approaches. The posterolateral and posteromedial approaches both develop the deep posterior compartment in the plane between the fibular and posterior tibial arteries, placing the fibular artery communicating branch (FACB) within the operative field ...

When Subtle Guiding Catheter‐Induced Stent Deformation Leads to Abluminal Guidewire Passage: Successful IVUS Tip‐Detection‐Guided Bailout

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Incomplete stent apposition at the proximal coronary artery may predispose to subtle guiding catheter–induced stent deformation, creating a gap between the stent and the vessel wall that facilitates inadvertent abluminal guidewire passage. We report a case in which balloon dilatation over an unrecognized abluminal guidewire resulted in severe ...

Spatial Mismatch Between Angiographic Obstruction and Plaque Destabilization in Acute Coronary Syndromes: A Conceptual Narrative Review

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT The identification of the “culprit lesion” in acute coronary syndromes (ACS) traditionally relies on coronary angiography, assuming that the most severe stenosis, abrupt occlusion, or largest filling defect marks the site of plaque destabilization.

Intravascular Lithotripsy in Left Main Stem Percutaneous Coronary Intervention

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background IVL is increasingly used for coronary calcium modification; however, prospective data for its use in LMS lesions are lacking. Aims To evaluate the feasibility, safety, and mechanical efficacy of intravascular lithotripsy (IVL) for calcium modification in calcified distal left main stem (LMS) percutaneous coronary intervention ...
