Implication

May support non-invasive LV assessment; confirms validation data but leaves open outcome trials before routine use.

Key Points

To assess the reliability and applications of radionuclide imaging in evaluating left ventricular function.
Utilized a gamma-camera interfaced with a computer for imaging.
Conducted validation studies comparing radionuclide imaging and standard contrast angiograms.
Performed clinical studies on both normal volunteers and patients.
Validation studies confirm the reliability of radionuclide imaging compared to contrast angiograms.
The technique effectively assesses the aetiology of chest pain and guides patient selection for cardiac surgery.
Evident effects of interventions like drug therapy and bypass surgery on ventricular performance.

Structured PICO

Does radionuclide imaging of the left ventricle reliably assess left ventricular function compared to standard contrast angiograms?

Population

Normal volunteers and patients

Intervention

Radionuclide imaging of the left ventricle (isotope angiocardiography)

Comparator

Standard contrast angiograms

Outcome

Assessment of left ventricular function (overall and segmental)surrogate

Radionuclide imaging is a reliable, non-invasive method for assessing left ventricular function at rest and during exercise.
