Bilateral Giant Cell Arteritis Presenting as Bilateral Sudden Vision Loss.

Giant cell arteritis (GCA) is the most common form of primary vasculitis and it mainly involves large to medium sized vessels. It is also referred to as temporal arteritis as it primarily affects the temporal artery. Ocular involvement frequently occurs in GCA; if not promptly diagnosed, it can cause devastating ocular complications including complete vision loss and permanent blindness.

Two-Decade Trends in the Prevalence of Atherosclerotic Risk Factors, Coronary Plaque Morphology, and Outcomes in Adults Aged ≤45 Years Undergoing Percutaneous Coronary Intervention.

Data are limited about the prevalence trends of risk factors, lesion morphology, and clinical outcomes of coronary artery disease in patients, aged ≤45 years, undergoing percutaneous coronary intervention (PCI), between the bare-metal stent (BMS; 1994 to 2002) and drug-eluting stent (DES; 2003 to 2012) eras. From the PCI database at the Cleveland Clinic, we identified 1,640 patients aged ≤45 years and without a history of coronary artery bypass grafting who underwent PCI from 1994 to 2012. There were 883 patients in the BMS era cohort with a mean follow-up period of 13.

Relationship of beam angulation and radiation exposure in the cardiac catheterization laboratory.

Objectives: The aim of this study was to analyze the relationship between beam angulation and air kerma in a modern cardiac catheterization laboratory.

Background: Recent reports have identified the merits of reducing radiation scatter, an important determinant of radiation dose in the catheterization laboratory. Radiation scatter is poorly characterized in the context of catheterization laboratories using modern digital equipment.

Predicting vascular complications during transfemoral transcatheter aortic valve replacement using computed tomography: a novel area-based index.

Background: Computed tomography (CT) imaging has not been systematically studied for predicting vascular complications during transcatheter aortic valve replacement (TAVR).

Methods: Clinical data were obtained from the electronic medical record and analysis was performed for each individual patient's iliofemoral CT angiogram. Sheath : femoral artery diameter ratio (SFAR) and sheath : femoral artery area ratio (SFAAR) were defined as the ratio of the sheath outer diameter to the femoral minimal lumen diameter (MLD) and sheath area to the femoral minimal lumen area (MLA), respectively.
