Background: Fatal arrhythmic events (FAEs), such as sudden cardiac death (SCD) and fatal ventricular arrhythmias, are a devastating complication in patients with coronary artery disease (CAD). Therefore, in this study we aimed to assess the incidence of FAEs in more recent Japanese patients with CAD and to examine whether risk stratification of FAEs can still be feasible using the left ventricular ejection fraction (LVEF).
Methods And Results: In the CREDO Kyoto PCI/CABG registry cohorts-2 and -3, there were 25,843 patients with LVEF data who received a first coronary revascularization (LVEF ≤35% group: N=1,671, 35%
Trauma-Induced Thoracic Stent Graft Migration and Dissecting Aneurysm Rupture.
Ann Thorac Surg Short Rep
June 2024
Thoracic endovascular aortic repair (TEVAR) is widespread. We report a case of graft migration and dissecting aneurysm rupture after trauma. An 82-year-old man with a history of TEVARs for chronic type B aortic dissection had sudden dyspnea and hemoptysis after falling from a stationary bicycle.

- A study investigated the effects of high-risk coronary artery plaques on late luminal narrowing and clinical events in patients after percutaneous coronary intervention.
- Over one year, the coronary artery lumen area decreased notably, especially in specific types of plaques, such as thin-cap and thick-cap fibroatheromas.
- Thin-cap fibroatheroma presence was linked to a higher risk of needing further revascularization procedures after ischemia, while no significant connection was found between coronary artery calcium levels and clinical outcomes within three years.
Article Synopsis
- The study examined the impact of very low levels of low-density lipoprotein cholesterol (LDL-C) on patients with coronary artery disease, using data from over 39,000 patients who underwent coronary revascularization.
- It was found that patients with very low LDL-C levels (<85 mg/dL) had more health issues and a higher risk of all-cause mortality compared to those with higher levels, revealing significant risks for various types of death and heart failure.
- Overall, the research suggests that lower LDL-C levels correlate with more serious health problems and increased mortality risk, highlighting the need for careful management of cholesterol levels in at-risk patients.
Background: Coronary aneurysms following drug-eluting stent implantation are rare but associated with adverse events.
Case Summary: An 80-year-old male admitted to our hospital with resting chest discomfort. He had undergone percutaneous coronary interventions (PCIs) with first-generation sirolimus-eluting stent (SES) implantation to the right coronary artery (RCA) and left anterior descending artery (LAD) 14 years ago.
