Drug Distribution and Stent Retention of Drug Eluting Stents [PDF]

, 2008
In this paper the examinations of drug eluting coronary stents are shown, such as the morphology of the coatings before expansion, drug distribution, the methodology and the value of stent retention.

Novel Use of Intravascular Lithotripsy for the Mobilization of an Entrapped Coronary Guidewire in a Heavily Calcified LAD/DB Bifurcation Lesion—A Case Report

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT A 64‑year‑old man with a Non–ST‑elevation myocardial infarction (NSTEMI) underwent coronary angiography, which revealed single‑vessel disease with a high‑grade proximal and a severely calcified mid‑LAD lesion just proximal to a diagonal branch (DB). Both the LAD and the DB were wired.

High‐Shear Environment Promotes Acute Carotid Stent Thrombosis in Patients With Tandem Lesions

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Stent thrombosis is a serious complication of angioplasty with stenting, as evidenced by the associated morbidity and mortality events. Its incidence is particularly elevated after emergent carotid stenting in patients with acute ischemic ...

Coronary stent thrombosis in bare metal stents

Saudi Medical Journal, 2004
OBJECTIVE: The incidence of coronary stent thrombosis has reduced with improved techniques and drugs. Nevertheless, clinical trials may not reflect real world practice due to the selective inclusion criteria, regional variations and more complex patients treated in day-to-day practice.

Five‐Year Clinical Outcomes of Biodegradable Versus Durable Polymer Drug‐Eluting Stents: A Propensity Score‐Matched Analysis of 4394 Patients

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Biodegradable‐polymer (BP) drug‐eluting stents (DES) were developed to mitigate potential late adverse events related to persistent durable polymers in durable‐polymer (DP) DES; however, contemporary long‐term real‐world comparative data remain limited. Aims We aimed to compare the 5‐year clinical outcomes of contemporary BP‐DES and

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 ...

A Case of Stent Fracture and Very Late Stent Thrombosis 15 Months after Drug-Eluting Stent Implantation

Majallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Bābul, 2009
BACKGROUND AND OBJECTIVE: Stent fracture (SF), in peripheral vessels and although in coronary arteries has been reported. Very late and after one year stent thrombosis in drug eluting stent (DES) is a rare phenomenon and its most frequent cause is ...

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.

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.
