Key result
Echocardiography correlated significantly with biplane angiocardiography for determining left ventricular end-diastolic volume (r=0.97) and ejection fraction (r=0.80).
Why the study?
Does echocardiography reliably quantify left ventricular volumes and ejection fraction compared to biplane angiocardiography in patients suspected of having heart disease?
Population

Supports echocardiography for noninvasive LVEDV and EF assessment in suspected heart disease; extends correlative data but leaves prospective validation open.
Observational (n=27)
Does echocardiography reliably quantify left ventricular volumes and ejection fraction compared to biplane angiocardiography in patients suspected of having heart disease?
Effect estimate: r = 0.97
Echocardiography is a reliable noninvasive technique for quantifying left ventricular chamber size and ejection fraction compared to invasive angiocardiography.
Pombo et al. (1971) conducted an observational in Suspected heart disease (n=27). Echocardiography vs. Biplane angiocardiography was evaluated on Left ventricular end-diastolic volume correlation (r = 0.97). Echocardiography correlated significantly with biplane angiocardiography for determining left ventricular end-diastolic volume (r=0.97) and ejection fraction (r=0.80).
