Intracardiac Echocardiography [PDF]

European Journal of Echocardiography, 2001
This article describes currently available intracardiac ultrasound (ICE) technology contrasting it with intravascular ultrasound (IVUS) highlighting their differences. Clinical applications in the electrophysiologic and cardiac catheterization laboratory are discussed and current limitations addressed.

Accuracy of quantitative echocardiographic measures of right ventricular function as compared to cardiovascular magnetic resonance

International Journal of Cardiology: Heart & Vasculature, 2016
Background: Many echocardiographic parameters have been proposed to evaluate right ventricular (RV) systolic function. We comprehensively assessed a wide range of quantitative echocardiographic parameters in a single cohort compared with same-day ...

A simplified definition of diastolic function in sepsis, compared against standard definitions

Journal of Intensive Care, 2019
Background Guidelines for grading diastolic dysfunction poorly categorize septic patients. We compared how well the American Society of Echocardiography (ASE) 2009 and 2016 definitions and a simplified definition categorized septic patients.

Assessment of right atrium dysfunction in patients with obstructive sleep apnea syndrome using velocity vector imaging

Cardiovascular Ultrasound, 2018
Background and Objectives This study aimed to assess the changes of RA function in patients with obstructive sleep apnea syndrome (OSAS) using velocity vector imaging (VVI) and to evaluate the application of VVI technology. Methods According to the apnea–

Reduced left atrial contractile strain with speckle tracking analysis predicts abnormal plasma NTproBNP in an asymptomatic community population

Cardiovascular Ultrasound, 2022
Background The left atrium (LA) is closely related to left ventricular diastolic function. Two-dimensional speckle tracking strain and strain rate (SR) imaging has been applied in the study of LA function.

Noncompaction of the left ventricle: a new cardiomyopathy is presented to the clinician

São Paulo Medical Journal
Noncompaction of the left ventricular myocardium is a morphogenetic abnormality involving loss of compaction of the myocardial fiber meshwork during intrauterine life. It is an extremely rare condition, accounting for only 0.05% of the cases evaluated in

Expanding the phenotype associated with SMARCC2 variants: a fetus with tetralogy of Fallot

BMC Medical Genomics, 2022
Background Coffin-Siris syndrome-8 (CSS8) is a rare autosomal dominant disorder caused by variants in SMARCC2, a core subunit of the chromatin-remodeling complex BRG1-associated factor (BAF).

Intraoperative echocardiography

The Annals of Thoracic Surgery, 1990
Intraoperative echocardiography has emerged as a new technique by which the cardiac surgeon can more precisely define the operative anatomy and physiology, immediately evaluate the results, and more accurately monitor left ventricular function in the operating room.
