Calcified Plaque Detachment: Alternative Calcified Plaque Modification After Coronary Intravascular Lithotripsy

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Calcified plaque (CP) detachment (CD) and calcium fracture (CF) can occur following coronary intravascular lithotripsy (IVL). The extent to which CF alone facilitates stent expansion during CP modification with IVL remains unclear. Aims This study aimed to investigate the clinical implications of IVL‐induced CD.

Evaluation of Treatment Response of Calcified Nodules and Nodular Calcified Lesions Using Mean Density on Coronary Computed Tomography Angiography

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Calcified nodules (CN) and nodular calcifications (NC) present significant challenges during percutaneous coronary intervention (PCI) because of their protruding morphology and high rigidity, which often result in inadequate stent expansion and suboptimal procedural outcomes.

Coating stent materials with polyhedral oligomeric silsesquioxane-poly(carbonateurea)urethane nanocomposites [PDF]

, 2009
The long-term efficacy of coronary or peripheral stenting is limited by in-stent restenosis (ISR), which occurs in 15 to 30% of patients and is attributed primarily to neointimal hyperplasia.

Length of carotid stenosis predicts peri-procedural stroke or death and restenosis in patients randomized to endovascular treatment or endarterectomy [PDF]

, 2013
BackgroundThe anatomy of carotid stenosis may influence the outcome of endovascular treatment or carotid endarterectomy. Whether anatomy favors one treatment over the other in terms of safety or efficacy has not been investigated in randomized trials ...

Comparative Effectiveness of Peripheral Angioplasty Strategies for 1-Year Restenosis in Lower Limb Artery Disease: A Retrospective Single-Center Analysis

Biomedicines
Background: Optimal endovascular strategy for lower limb peripheral artery disease (PAD) remains debated, particularly regarding 1-year restenosis. Aim: To evaluate the association between drug-coated balloon (DCB)-based angioplasty and 1-year restenosis

Final 2‐Year Results of the REFORM Study: A Randomized Trial of Biolimus DCB Versus Paclitaxel DCB for In‐Stent Restenosis

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background In the REFORM trial, treatment of coronary in‐stent restenosis with a Biolimus A9™ drug‐coated balloon (BCB) was found to be inferior with respect to in‐segment percentage stenosis at 6‐months in comparison to treatment with a standard paclitaxel coated paclitaxel‐coated balloon (PCB). Aims In this manuscript, the final prespecified

Buddy Wire–Augmented Intravascular Lithotripsy in Refractory Calcified Coronary Lesions: A Five‐Case Series

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Heavily calcified coronary lesions remain a major challenge in percutaneous coronary intervention (PCI), often limiting the effectiveness of intravascular lithotripsy (IVL). We report a five‐case series in which IVL failed to achieve adequate lesion modification but was successfully augmented by the addition of one or more buddy wires.
