Background: Valvular heart disease is an important contributor to cardiovascular morbidity and mortality and remains underdiagnosed. Deep learning analysis of electrocardiography (ECG) may be useful in detecting aortic stenosis (AS), aortic regurgitation (AR), and mitral regurgitation (MR).

Objectives: This study aimed to develop ECG deep learning algorithms to identify moderate or severe AS, AR, and MR alone and in combination. Read More

Learning Objectives: After studying this article, the participant should be able to: (1) understand the functional significance of nasal anatomy as it relates to rhinoplasty and perform a comprehensive functional nasal assessment. (2) Identify the anatomical level of obstruction based on the authors' algorithmic approach and understand the current evidence supporting operative techniques for correcting nasal airway obstruction from septal deformity, inferior turbinate hypertrophy, internal nasal valve collapse, external nasal valve collapse. (3) Understand the current evidence supporting operative techniques for correcting nasal airway obstruction from septal deformity, inferior turbinate hypertrophy, internal nasal valve collapse, and external nasal valve collapse.

Objective: Decompressive craniectomy (DC) is widely used to treat intracranial hypertension following severe head injury. However, impairments of cerebrospinal fluid (CSF) hydrodynamics such as hydrocephalus and subdural effusion are common complications that occur after DC. Therefore, monitoring of intracranial pressure is a staple of neurocritical care post-DC. Read More

Two French bulldogs and one English bulldog affected by pulmonary valve stenosis and referred for pulmonary balloon valvuloplasty were diagnosed with different abnormalities of the external jugular veins. The diagnosis included unilateral absence of the right external jugular vein and bilateral hypoplasia of the external jugular veins, associated with persistent left cranial vena cava. Vascular ultrasound and computed tomography were used for the diagnosis. Read More

The aim of the study was 1) to describe a novel combination of techniques that permit immunohistochemistry imaging of Schlemm's canal inlet (SIV) and outlet (SOV) valve-like structures, 2) to identify tissue-level SIV adhesive relationships linking the trabecular meshwork (TM) to hinged collagen leaflets at the Schlemm's canal (SC) external wall, and 3) to determine whether the SIV lumen wall's adhesive vascular markers are similar to those of the SC inner wall endothelium. Anterior segments of 16 primates underwent immunohistochemistry (IHC) labeling. We perfused fluorescent microspheres into 12 of the eyes. Read More
