Changes in hemodynamics of pulmonary artery using Flowire in a canine model of acute pulmonary thromboembolism

Animal Models and Experimental Medicine, EarlyView.
This study investigated changes in pulmonary artery hemodynamics using a Flowire catheter and evaluated the accuracy of Doppler echocardiography in dogs with acute pulmonary thromboembolism (PTE). Ten healthy beagles were anesthetized, and acute pulmonary hypertension (PH) was induced by injecting 300‐μm dextran microspheres.

Role of Two- Dimensional Speckle Tracking Strain versus Conventional Echocardiography in the Assessments of Left Ventricular Systolic Function in Middle-aged Hypertensive Patients.

مجلة كلية الطب, 2019
Background: Systemic hypertension is a major risk factor for cardiovascular accidents. The early management of its complication on the heart plays an important role in the outcome of the disease. Hypertension is associated with changes in several aspects

The effects of cardioversion and defibrillation on left ventricular systolic function.

Japanese Circulation Journal, 1992
The purpose of this research was to evaluate the left ventricular systolic function behavior after cardioversion and defibrillation. The study included 18 adult patients who had direct current cardioversion or defibrillation performed for conversion of spontaneous or induced arrhythmias.

Noradrenergic and cholinergic innervation of the normal human heart and changes associated with cardiomyopathy

The Anatomical Record, EarlyView.
Abstract Autonomic nerves are crucial in cardiac function and pathology. However, data on the distribution of cholinergic and noradrenergic nerves in normal and pathologic human hearts is lacking. Nonfailing donor hearts were pressure‐perfusion fixed, imaged, and dissected. Left ventricular cardiomyopathy samples were also obtained.

Echocardiographic Evaluation of Ventricular Function—For the Neonatologist and Pediatric Intensivist

Frontiers in Pediatrics, 2018
In the neonatal and pediatric intensive care setting, bedside cardiac ultrasound is often used to assess ventricular dimensions and function. Depending upon the underlying disease process, it is necessary to be able to evaluate the systolic and diastolic

Left ventricular systolic and diastolic function in the hypertrophied ventricle.

Japanese Circulation Journal, 1990
To investigate left ventricular (LV) systolic and diastolic function in cardiac hypertrophy, we analysed LV pressure (catheter tip-manometer) and simultaneously performed cineangiography in 24 patients with systemic hypertension (HT), 25 patients with hypertrophic cardiomyopathy (HCM) and 25 normal subjects.

Morphological and morphometric aspects of the equine aortic valve: New insights for comparative studies in mammals

The Anatomical Record, EarlyView.
Abstract New data on the equine aortic valve obtained using advanced techniques is especially important given the greater availability of animal models for translational research. Here we characterized the morphological and morphometric aspects of the equine aortic valve from 60 healthy hearts collected at equine abattoirs.
