Supraglottic Laryngeal Mass
A 60-year-old Hispanic male with a history of smoking presented to the emergency department with complaint of dysphagia for the past two months. Additional symptoms included progressive shortness of breath and stridor. CT results from an outside institution showed 80% airway obstruction. Despite the findings, the patient’s vitals were normal, with respirations of 20 and an initial room air oxyg...
متن کاملCauliflower-like mass attached to the left atrial roof.
A 75-year-old man was referred to our hospital for investigation of a suspected mass in the left atrium (LA) and asymmetric septal hypertrophy of the left ventricle without significant obstruction detected by screening transthoracic echocardiography of atrial fibrillation (AF). Transesophageal echocardiography revealed dynamic smoke-like echo filling in LA and a cauliflower-like, large (22×16 m...
متن کاملA Tricuspid Valve Mass Attached to Papillary Muscle
BACKGROUND Cardiac myxoma is the most common benign heart tumor which can arise in any of the cardiac chambers, valves or related great veins. Diagnosis of a myxoma arising from the tricuspid valve apparatus is exceptional. We present a rare case of myxoma in a tricuspid valve attached to papillary muscle. CASE DETAILS A 45-year-old man was referred to our center for the evaluation dyspnea an...
متن کاملEmploying Internal Flexible Wall as Mass Absorber in Tanks Subjected to Harmonic Excitations
The possibility of employing internal wall as mass absorber in rectangular water storage tanks subjected to harmonic ground motion excitation is investigated in this paper. Internal walls are used in these tanks usually for service performance purposes, which could be used as mass absorber to control seismic demand on tank's exterior walls. Derivation of the response of the coupled system inclu...
متن کاملExact solution of a model of a vesicle attached to a wall subject to mechanical deformation
Area-weighted Dyck-paths are a two-dimensional model for vesicles attached to a wall. We model the mechanical response of a vesicle to a pulling force by extending this model. We obtain an exact solution using two different approaches, leading to a q-deformation of an algebraic functional equation, and a q-deformation of a linear functional equation with a catalytic variable, respectively. Whil...
