Estimating Left Ventricular Filling Pressure by Echocardiography

open access: yesJournal of the American College of Cardiology, 2017
The diagnosis of heart failure may be challenging because symptoms are rather nonspecific. Elevated left ventricular (LV) filling pressure may be used to confirm the diagnosis, but cardiac catheterization is often not practical. Echocardiographic indexes are therefore used as markers of filling pressure.This study investigated the feasibility and ...

Invasive Right Ventricular Pressure-Volume Analysis: Basic Principles, Clinical Applications, and Practical Recommendations

open access: yesCirculation: Heart Failure, 2021
Supplemental Digital Content is available in the text. Right ventricular pressure-volume (PV) analysis characterizes ventricular systolic and diastolic properties independent of loading conditions like volume status and afterload.

Determinants of left atrial reservoir and pump strain and use of atrial strain for evaluation of left ventricular filling pressure

open access: yesEuropean Heart Journal-Cardiovascular Imaging, 2021
Aims The aim of this study is to investigate determinants of left atrial (LA) reservoir and pump strain and if these parameters may serve as non-invasive markers of left ventricular (LV) filling pressure. Methods and results In a multicentre study of 322

Predictive Value of Right Ventricular Pressure Measurement for Residual Pulmonary Stenosis in Tetralogy Repair

open access: yesSiriraj Medical Journal, 2022
Objective: The long-term outcome of tetralogy of Fallot repair depends on an adequate relief of right ventricular outflow tract obstruction and preservation of the pulmonary valve function.

Influence of Right Ventricular Filling Pressure on Left Ventricular Pressure and Dimension [PDF]

open access: yesCirculation Research, 1974
The effects of alterations in the diastolic filling pressure of the right ventricle on left ventricular (LV) geometry and filling pressure were studied in six isolated, supported canine hearts. This experimental preparation permitted graded increments in right ventricular (RV) end-diastolic pressure while LV cardiac output, heart rate, and mean aortic ...

Actividad inotrópica inducida por el derivado carbamacepina-alquino en un modelo de corazón aislado y perfundido a flujo constante

open access: yesBiomédica: revista del Instituto Nacional de Salud, 2011
Introducción. Existen pocos datos con respecto a los efectos de la carbamacepina y sus derivados en el aparato cardiovascular; además, el mecanismo molecular y su sitio de acción celular no son claros. Objetivo.

Understanding cardiopulmonary interactions through esophageal pressure monitoring

open access: yesFrontiers in Physiology, 2023
Esophageal pressure is the closest estimate of pleural pressure. Changes in esophageal pressure reflect changes in intrathoracic pressure and affect transpulmonary pressure, both of which have multiple effects on right and left ventricular performance ...

Pressure-related ventricular tachycardia

open access: yesInternational Journal of Cardiology, 1990
A case with syncope on exertion and paced heart block is presented. Non-sustained ventricular tachycardia was seen on Holter monitoring and reproduced repeatedly by either exercise or an injection of an alpha agonist, but not with provocative electrophysiology.

Effects of mercury on the arterial blood pressure of anesthetized rats

open access: yesBrazilian Journal of Medical and Biological Research, 1999
The available data suggests that hypotension caused by Hg2+ administration may be produced by a reduction of cardiac contractility or by cholinergic mechanisms.
