Assessment of right ventricular function by isovolumic contraction acceleration before and after percutaneous closure of atrial septal defects:A preliminary study February 2014 Assessment of right ventricular function by isovolumic Assessment of right ventricular function by isovolumic contraction acceleration before and after percutaneous closure of atrial septal defects:A preliminary study Introduction Atrial septal defect (ASD) is the most commonly encoun-tered congenital heart disease in adults and constitutes 10% of all congenital heart diseases (1).

Assessment of sustained effects of levosimendan on right

Before and 5 days after the initiation of infusions, functional class was assessed, NT-proBNP levels and LVEF, RVEF, using tissue Doppler imaging, RV isovolumic myocardial acceleraton (IVA), peak myocardial velocity during isovolumic contraction (IVV), peak systolic velocity during ejection period (Sa), early (E) and late (A) diastolic Echocardiographic Assessment of the Right Ventricle, from A right ventricular ejection fraction of >45% and an absolute value of global longitudinal strain of >21% reflect normal systolic function. The significance of dp/dt, the right myocardial performance index and isovolumic myocardial acceleration, is also discussed along with the parameters of right ventricular diastolic function. Efficacy of Isovolumic Acceleration in Assessing Right Objective:The aim of the study was to determine usefulness of isovolumic acceleration to assess right ventricular function in patients with pulmonary hypertension. Background:Right ventricular dysfunction is a powerful predictor of adverse outcomes in patients with pulmonary hypertension. Although isovolumic acceleration is a sensitive and relatively load-independent parameter for

Non-invasive assessment of ventricular forcefrequency

Objective:To describe the first clinical application of a novel tissue Doppler derived index of contractility, isovolumic acceleration (IVA), in the assessment of the ventricular myocardial forcefrequency relation (FFR) in the univentricular heart (UVH). Design:Prospective study. Setting:Tertiary referral centre.

Relation of left ventricular isovolumic relaxation time In all patients, isovolumic relaxation time was significantly and negatively correlated with the acceleration of the E wave, showing its fundamental relation to the force responsible for early diastolic filling (r = -0.71 for left ventricular hypertrophy, and -0.74 for ischaemic heart disease, p value < 0.01).

Relation of left ventricular isovolumic relaxation time

In all patients, isovolumic relaxation time was significantly and negatively correlated with the acceleration of the E wave, showing its fundamental relation to the force responsible for early diastolic filling (r = -0.71 for left ventricular hypertrophy, and -0.74 for ischaemic heart disease, p value < 0.01). Tricuspid annular isovolumic acceleration is more useful Tricuspid annular isovolumic acceleration is more useful for the assessment of right ventricular systolic function in patients after repair of tetralogy of Fallot with pulmonary regurgitation.
