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.

Three-Dimensional CT for Preprocedural Planning of PCI for Ostial Right Coronary Artery Lesions: A Randomized Controlled Pilot Trial.

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.

Objective: To identify strategies to prevent and treat delayed gastric emptying (DGE) after pancreatic surgery.

Background: Among all complications of pancreatic surgery, DGE has the largest impact on prolonged hospital stay. Several randomized controlled trials (RCTs) have addressed DGE after pancreatic surgery, either as primary or as secondary outcome.

Objective: Extraversion is a fundamental personality dimension that contributes to an individual's overall health and well-being. Many studies have examined the neural bases of extraversion but these results are inconsistent. This study adopted a meta-analysis approach to examine the brain activity correlates of extraversion by incorporating functional neuroimaging studies in the context of positive affect/emotional stimuli.
