Why the study?

Does objective analysis improve the reproducibility of left ventriculogram assessments compared to subjective visual inspection?

Population

35 left ventricular cineangiograms

Comparison

Objective analysis using standard quantitative… vs Subjective analysis using only visual inspection

Design

Cross-sectional

Implication

Objective ventriculogram analysis shows higher reproducibility than subjective assessment; leaves open effects on clinical decisions.

Structured PICO

Does objective analysis improve the reproducibility of left ventriculogram assessments compared to subjective visual inspection?

Population

35 left ventricular cineangiograms

Intervention

Objective analysis using standard quantitative techniques for ventricular volumes and a newly devised quantitative system for wall motion

Comparator

Subjective analysis using only visual inspection

Outcome

Reproducibility of end-diastolic volume, end-systolic volume, ejection fraction, and regional wall motion assessmentssurrogate

Objective quantitative analysis of left ventriculograms is necessary to ensure reproducibility and accuracy, as subjective visual inspection has a significant error rate.
