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 ...

Clinical outcomes of rotational atherectomy in severely calcified in-stent restenosis: a single-center, retrospective study [PDF]

, 2019
2019-05Neointimal calcification after stent implantation has been reported as one of the forms of neoatherosclerosis. There are a few patients with in-stent restenosis (ISR) and an undilatable calcified neointima who require rotational atherectomy to ...

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.

Mechanisms and Management of Acquired Aseptic Intracardiac Communications After Transcatheter Aortic Valve Implantation: Single‐Center Case Series Insights

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Acquired aseptic intracardiac communications (AICCs) are rare but clinically relevant structural complications following transcatheter aortic valve implantation (TAVI), typically resulting from mechanical injury to the aortic annulus, interventricular septum, or adjacent structures.

Balloon‐Stopper Retrieval and Peripheral Parking After Inadvertent Ostial Right Coronary Stent Deployment

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Percutaneous treatment of right coronary artery (RCA) ostial lesions is technically challenging due to cardiorespiratory motion. Case Summary We describe a 70‐year‐old man undergoing PCI for an ostial RCA lesion where a forceful cough caused complete stent expansion within the aortic root.

Engineering an artificial trachea: Quantitative benchmarks and modular strategies for mechanics, epithelialization, and vascular integration

FlexMat, EarlyView.
In this work, we first examine the limitations of surgical repair and stenting, including migration, granulation, mucus plugging, and infection. We then translate these failures into engineering constraints involving geometry, mechanics, fixation, degradation, junctional stress, and remodeling.

Optical coherence tomography (OCT) vs intravascular ultrasound (IVUS) in diagnosing the mechanisms of in-stent restenosis in drug eluting stents

Romanian Journal of Cardiology
In-stent restenosis remains a recognized complication of percutaneous coronary intervention (PCI). Conventional two-dimensional angiography is limited to visualization of the coronary lumen and provides inadequate assessment of in-stent restenosis ...

Hemodynamic Significance of APEXCT Coronary Angiography Combined With Dynamic CT Myocardial Perfusion Imaging in Assessing Restenosis After Coronary Stenting

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study aimed to evaluate the hemodynamic significance of in‐stent restenosis (ISR) by using a combined anatomical‐functional approach with photon‐counting CT coronary angiography (APEX‐CT CTA) and dynamic CT myocardial perfusion imaging (CT‐MPI). We prospectively enrolled 239 symptomatic patients at least 9 months after PCI.
