Based on an anonymous questionnaire obtained from 102 Japanese in-patients at a rural Japanese hospital who underwent coronary angiography, the patients understanding of information about the procedure, their perception of consent and their attitude toward it were investigated. The patients were able to recall 63.8% of the contents of the information. There was a statistically significant correlation between the patients' educational status and the recall test score of the information. Older (65 years old and above) patients had a tendency to entrust decision making to their physicians. Only 19.6% of the patients made the decision to undergo a coronary angiography by themselves. After being informed of the risks 40.2% of the patients felt more anxious. In conclusion, our patients could not recall the contents of the information sufficiently. There still existed a tendency to entrust important decisions to the physician especially in older patients. The patients had a tendency not to face difficult problems solely by themselves but with the support of family members.

Coronary artery dominance influences the distribution of calcified plaques in the coronary tree.
Coron Artery Dis

Department of Medicine, Lundquist Institute at Harbor-UCLA Medical Center, Los Angeles.
Background: Coronary artery dominance is determined by the coronary artery emitting the posterior descending artery. In the left dominant system, a greater proportion of coronary flow enters the left coronary artery, potentially influencing calcified plaque development in the left anterior descending artery (LAD).
Methods: This retrospective single-center cohort study analyzed patients who underwent computed tomography angiography from September 2006 to December 2022 at Harbor-UCLA in Los Angeles, California.

Background: Geographic stent-ostium mismatch is an important predictor of target lesion failure after percutaneous coronary intervention of an aorto-ostial right coronary artery lesion. Optimal visualization of the aorto-ostial plane is crucial for precise stent implantation at the level of the ostium. This study investigates whether preprocedural 3-dimensional computed tomography (3DCT), with determination of the optimal viewing angle, would allow for more precise stent implantation and reduce procedure time, contrast, and radiation dose.

Fibromuscular dysplasia (FMD) is a non-atherosclerotic, non-inflammatory vascular disease of medium-sized arteries that causes abnormal cellular growth in arterial walls and most commonly affects young to middle-aged women (20-50 years of age). While FMD often involves the renal arteries, it can affect any arterial bed. FMD has a characteristic angiographic appearance of a "string of beads.

Artificial intelligence-based quantitative coronary angiography (AI-QCA) was introduced to address manual QCA's limitations in reproducibility and correction process. The present study aimed to assess the performance of an updated AI-QCA solution (MPXA-2000) in lesion detection and quantification using manual QCA as the reference standard, and to demonstrate its superiority over visual estimation. This multi-center retrospective study analyzed 1,076 coronary angiography images obtained from 420 patients, comparing AI-QCA and visual estimation against manual QCA as the reference standard.

Background: Coronary sinus (CS) lead placement in persistent left superior vena cava (PLSVC) cases is challenging because of the poor backup force of the guiding catheter within the enlarged CS. Active fixation Quadripolar leads (Attain Stability™ Quad 4798, Medtronic) can expand choice to CS branches with limited access; however, no cases of anchoring to the main body of the CS have been published to date.
Case Summary: We describe a case of cardiac resynchronization therapy pacemaker upgrade in a 79-year-old female who developed pacing-induced cardiomyopathy after pacemaker implantation via the right superior vena cava (SVC) for atrioventricular block eight years ago wherein PLSVC was revealed during the procedure.
