Mechanism of Drug-Eluting Stent Thrombosis Diagnosed by Histopathological Evaluation of Directional Coronary Atherectomy Specimen

JACC: Case Reports, 2023
An 89-year-old man with a history of percutaneous coronary intervention using a sirolimus-eluting stent presented with recurrent in-stent occlusion. Pathological assessment of the neointima resected via directional coronary atherectomy revealed a double ...

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.

Combined percutaneous coronary atherectomy and coronary angioplasty: Experience in 19 consecutive patients [PDF]

, 1990
Among 82 patients undergoing coronary atherectomy, 19 (23%) underwent this procedure in combination with coronary angioplasty. The most frequently involved vessel was the left anterior descending coronary artery.

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.

Dataset of calcified plaque condition in the stenotic coronary artery lesion obtained using multidetector computed tomography to indicate the addition of rotational atherectomy during percutaneous coronary intervention

Data in Brief, 2016
Our data shows the regional coronary artery calcium scores (lesion CAC) on multidetector computed tomography (MDCT) and the cross-section imaging on MDCT angiography (CTA) in the target lesion of the patients with stable angina pectoris who were ...

Intravascular lithotripsy in heavily calcified unprotected left main with involvement of LAD ostium taking-off at extreme angulation - Taking upon an ‘Armageddon’

IHJ Cardiovascular Case Reports, 2021
Calcific left main disease poses a tricky situation for various atherectomy devices including rota-ablation, orbital and directional atherectomy. However, with the advent of intravascular lithotripsy (IVL) in the armamentarium for complex percutaneous ...

Coronary Perforation During Excimer Laser Angioplasty in a Patient With Prior Thoracic Radiotherapy

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Management of heavily calcified coronary lesions remains challenging despite advances in plaque‐modifying technologies. Excimer laser coronary angioplasty (ELCA) is an effective adjunctive strategy with a low risk of no‐reflow. Case Summary A 75‐year‐old woman with non–ST‐segment elevation acute coronary syndrome and severe left ...

Quantitative angiographic comparison of the immediate success of coronary angioplasty, coronary atherectomy and endoluminal stenting [PDF]

, 1990
Coronary atherectomy and coronary stenting effectively reduce the severity of coronary artery stenoses, but direct comparisons of these interventions with conventional balloon angioplasty have not been performed.

Rotational Atherectomy-Assisted Crossing of a Complex Right Coronary Artery Lesion Using the Retrograde Approach

Case Reports in Cardiology, 2021
Chronic total occlusion lesions present a major challenge for the interventional cardiologist. In this case, we report the successful use of rotational atherectomy to facilitate retrograde percutaneous coronary intervention of a complex totally occluded ...

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.
