When it all comes down to pressure: right ventricular ejection fraction at cardiac catheterisation

Thermodilution right ventricular ejection fraction. Remaining questions.

Right Ventricular Ejection Fraction During Exercise

The response of right ventricular ejection fraction (RVEF) during exercise and its relationship to the location and extent of coronary artery disease are not fully understood. We have recently developed and validated a new method for scintigraphic evaluation of RVEF using rapid multiple-gated equilibrium scintigraphy and multiple right ventricular regions of interest. The technique has been app...

It is time to look at heart failure with preserved ejection fraction from the right side.

H eart failure (HF) with preserved left ventricular (LV) ejection fraction (EF; or HFpEF) is seen in approximately half of patients with HF and confers morbidity and mortality similar to that of HF with reduced left ventricular ejection fraction (HFrEF). 1 HFpEF has been characterized by abnormal LV dia-stolic function, abnormal LV-central vascular coupling, impaired systolic reserve and chrono...

Equilibrium radionuclide angiocardiography for the evaluation of right ventricular ejection fraction in patients with cardiac disorders.

OBJECTIVE To compare correlation between right ventricular ejection fraction (RVEF) derived from MRI and equilibrium radionuclide angiocardiography (ERNA) depicted from the left anterior oblique (LAO) view and anterior (ANT) view [designated as ERNA (LAO) and ERNA (ANT), respectively]. METHODS Twenty-one patients with cardiac disorders received ERNA and cardiac MRI examination within 2 weeks ...

Is It Still Valid to Measure Ejection Fraction When There Are New Deformation Indexes to Evaluate Ventricular Function? Agonist

An echocardiographic study helps in the assessment of systolic and diastolic left ventricular function due to potential clinical implications over the treatment and the prognosis of different heart diseases. Systolic function depends on three factors: the left ventricular (LV) function, arterial coupling (ventriculoarterial coupling) and blood volume. In the particular case of the left ventricu...
