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

open access: yesCatheterization 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.

Restenosis and progression of coronary atherosclerosis after coronary angioplasty [PDF]

open access: yes, 1988
The relation between restenosis and progression or atherosclerosis in other coronary segments after angioplasty was studied in 98 consecutive patients with 110 coronary stenoses successfully treated with angioplasty.

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

open access: yesCatheterization 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.

Intravascular Lithotripsy in Left Main Stem Percutaneous Coronary Intervention

open access: yesCatheterization 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 ...

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

open access: yesCatheterization 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.

Intractable coronary fibromuscular dysplasia leading to end‐stage heart failure and fatal heart transplantation

open access: yesESC Heart Failure, 2020
Coronary fibromuscular dysplasia is uncommon, and even rarer its unstable and recurrent course. We present the unique case of a 52‐year‐old woman who underwent in total 12 coronary angiographies and three percutaneous coronary intervention within 24 ...

The Current State of MicroRNAs as Restenosis Biomarkers

open access: yesFrontiers in Genetics, 2020
In-stent restenosis corresponds to the diameter reduction of coronary vessels following percutaneous coronary intervention (PCI), an invasive procedure in which a stent is deployed into the coronary arteries, producing profuse neointimal hyperplasia. The

Restenosis after coronary angioplasty: An overview

open access: yesJournal of the American College of Cardiology, 1991
Despite substantial basic and clinical efforts to address the problem of restenosis after percutaneous coronary intervention, effective preventive therapies have not yet been developed. Nevertheless, the accumulated information has provided much insight into the process of restenosis in addition to allowing standards to be developed for adequate ...

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

open access: yes, 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.

The Endothelial CXCR Family in Vascular Health and Disease

open access: yesiNew Medicine, EarlyView.
ABSTRACT Endothelial cells (ECs) form the dynamic interface between blood and tissue, serving as key regulators of vascular homeostasis, inflammation, and repair. Among the molecular systems governing endothelial behavior, the C‐X‐C motif chemokine receptor (CXCR) family—originally characterized in immunology for its roles in leukocyte trafficking and ...
