Optimal Dual Antiplatelet Therapy Duration For Carotid Artery Stenting On the Basis of Angioscopic Findings [PDF]

Stroke: Vascular and Interventional Neurology
Background Dual antiplatelet therapy plays a crucial role in preventing thrombosis in the perioperative period of carotid artery stenting (CAS); however, it has been associated with a risk of hemorrhagic complications. A standard regimen for the duration

Detection of vulnerable atherosclerotic plaque during thoracic endovascular aortic repair using nonobstructive angioscopy

Journal of International Medical Research, 2018
An angioscope was used to observe the intima of the aorta in an 82-year-old patient who had undergone thoracic endovascular aortic repair. The aortic angioscopic findings showed vulnerable plaques from the ascending aorta to the aortic arch that had not ...

Clarification of embolic source in ischaemic stroke by non-obstructive general angioscopy [PDF]

Open Heart
Background Aortogenic stroke is an important subtype of embolic strokes, yet lacks a diagnostic method for proactive identification. Non-obstructive general angioscopy (NOGA) is a catheter-based technique to observe spontaneously ruptured aortic plaques (

Long-term clinical significance of the presence of puff-chandelier ruptures detected by non-obstructive aortic angioscopy [PDF]

Scientific Reports
Although studies have reported various patterns of atherosclerotic aortic plaques (AAPs) detected by non-obstructive aortic angioscopy (NOA), the long-term outcomes associated with AAPs such as puff-chandelier rupture atheromatous plaque (PCR), remain ...

Coronary arterial repair in patients with stable angina pectoris or acute coronary syndrome after ultrathin biodegradable polymer sirolimus‐eluting stent implantation at 1‐year follow‐up by coronary angioscopy

Catheterization and Cardiovascular Interventions, Volume 102, Issue 6, Page 1012-1019, November 15, 2023., 2023
Abstract Background Imaging modality‐based evidence is limited that compares the extent of coronary arterial repair after percutaneous coronary intervention between patients with stable angina pectoris (SAP) and those with acute coronary syndrome (ACS). Methods Between December 2018 and November 2021, a single‐center, nonrandomized, observational study
