Coronary Vasospasm-Induced Myocardial Infarction: An Uncommon Presentation of Unrecognized Hyperthyroidism.

Hyperthyroidism can present with cardiac issues, such as tachycardia, atrial fibrillation, and high output congestive heart failure. Rare case reports of coronary vasospasm leading to myocardial infarction (MI) are published. Of these cases, many are known to be hyperthyroid prior to cardiac presentation.

Beamforming algorithms for endocardial border detection.

Background: Software-based beamforming which utilizes delay and standard beamforming is a signal processing technique that temporarily stores data from each probe element to improve specular reflections to improve the image resolution. We compared a software algorithm which uses delay and standard beamforming with delay and sum beamforming in standard, hardware to evaluate endocardial borders and need for echo contrast.

Methods: In this prospective study, eligible participants were ≥18 years of age referred clinically for transthoracic echocardiograms.

Outcomes of patients undergoing elective percutaneous coronary interventions in the ambulatory versus in-hospital setting.

Objectives: To compare outcomes of elective percutaneous coronary interventions (PCI) in same-day discharge and overnight hospital stays.

Background: Advances in PCI techniques and equipment have allowed same-day discharge after elective PCI. In this study, we investigated the safety of same-day discharge ambulatory PCI in patients according to age, creatinine, and ejection fraction (ACEF) scores.

Clinical outcomes after repair of left atrial esophageal fistulas occurring after atrial fibrillation ablation procedures.

Background: The initial experience with left atrial esophageal fistula (LAEF) secondary to atrial fibrillation (AF) ablation procedures revealed a near-universal mortality. A comprehensive description of the principles of LAEF repair in the modern era and its resulting impact on morbidity and mortality are lacking in the literature.

Objective: To describe the presentation, surgical management, and outcomes of patients with LAEF.

Wound fluids: a window into the wound environment?

Wound healing of the skin is a complex biologic process involving temporal interactions between numerous types of cells, extracellular matrix molecules, and soluble factors. The process of repair can be viewed as involving 3 or 4 phases: homeostasis, inflammation, synthesis, and remodeling. These phases occur at different times and differ in their cellular, biochemical, and physiologic requirements.
