Stent fracture is one of the complications of drug-eluting stent implantation. An 84-year-old man underwent coronary angiography for unstable angina. He had diffuse severe stenosis and calcified plaque in the left anterior descending artery and underwent percutaneous coronary intervention (PCI) in the left anterior descending artery for severe stenosis with chest pain.

However, the association between computed tomography (CT) images and vulnerable plaques detected on NOGA remains unknown.
Methods And Results: We investigated 101 patients (67±11 years; women, 13.
Article Synopsis
- * Researchers looked at 196 NSTE-ACS patients treated from March 2019 to October 2022 and divided them based on whether they had a CT scan and if it showed any perfusion defects.
- * Findings indicated that patients with CT-detected perfusion defects had faster times from arrival to coronary angiography (CAG) and lower peak CK levels, suggesting that non-gated CT could aid in quicker diagnoses and treatments in NSTE-ACS cases. *
Atrial fibrillation (AF) is an independent risk factor for stroke and systemic embolism. Cardiogenic and aortogenic emboli are causes of stroke or systemic embolism. Non-obstructive general angioscopy (NOGA) can be used to diagnose aortic intimal findings, including thrombi and atherosclerotic plaques, but little is known about NOGA-derived aortic intimal findings in patients with AF.

- The study examined how the angle of the left subclavian artery affects the duration of percutaneous coronary interventions (PCI) in patients with acute coronary syndrome (ACS).
- Patients with a more tortuous artery (angles less than 70 degrees) were generally older, more likely to be female, and had higher rates of hypertension and artery calcification.
- A significant negative correlation was found between the tortuosity of the artery and the time taken to complete the PCI, indicating that higher tortuosity leads to longer procedure times.
A cerebral infarction (CI) is a common complication of coronary angiography (CAG); however, repeated CIs in the immediate period after a CAG have not been reported yet. The patient in the present study experienced left upper quadrant blindness immediately after internal thoracic arteriography, and magnetic resonance imaging (MRI) showed a high-intensity area in the right occipital lobe. Despite the administration of antithrombotic therapy, the patient became transiently comatose for 6 hours.

We hypothesized that an in-stent thrombus (IS-thrombus) detected by coronary angioscopy (CAS) after stent implantation would be associated with high bleeding risk.
Methods: This study included 208 patients who underwent CAS at 2 weeks after stent implantation for an acute myocardial infarction.
