Grading diastolic function by echocardiography: hemodynamic validation of existing guidelines
BACKGROUND While echocardiographic grading of left ventricular (LV) diastolic dysfunction (DD) is used every day, the relationship between echocardiographic DD grade and hemodynamic abnormalities is uncertain. METHODS We identified 460 consecutive patients who underwent transthoracic echocardiography within 24 h of elective left heart catheterization and had: normal sinus rhythm, no confoundi...
متن کاملEvaluation of Left Ventricular Diastolic Function by Echocardiography
The normal cardiac cycle consists of two phases, systole and diastole, which are repeated over time to maintain an adequate cardiac output. The systole has been traditionally regarded as the main capital phase, leaving at diastole as a secondary process and almost forgotten. However, today we know that diastole is a crucial stage in the functioning of the heart. Its dysfunction can lead even in...
متن کاملExercise 2D Strain Echocardiography: Is it Feasible?
During the last few decades, the continued growth and expansion of stress echocardiography in daily clinical practice has led to the search and development of new and more quantitative technologies in an attempt to reduce the subjectivity of wall motion analysis by conventional visual method. (1) The evaluation of coronary flow reserve by Doppler echocardiography and myocardial deformation para...
متن کاملNew universal strain software accurately assesses cardiac systolic and diastolic function using speckle tracking echocardiography.
BACKGROUND We have developed new universal strain software (USS) that can be used to perform speckle tracking of any Digital Imaging and Communications in Medicine (DICOM) image, regardless of the ultrasound system used to obtain it. METHODS Fifty patients prospectively underwent echocardiography immediately prior to cardiac catheterization. Biplane peak global longitudinal strain (GLS), peak...
متن کاملThe influence of Asthma on Right Ventricular Systolic and Diastolic Function in Children according to Tissue Doppler Echocardiography
Introduction:Asthma is the most common chronic inflammatory condition affecting the lower airways among children. Asthma may influence right ventricular (RV) function and patients may develop right ventricular hypertrophy, pulmonary hypertension and cor pulmonale. The main objective of this study is to determine RV dysfunction in asymptomatic asthmatic children as detected by ti...
