Key result
Fast cine MR imaging showed reduced right ventricular ejection fraction in 31% of cardiac patients; while RVEF correlated with LVEF (r=0.55, P<0.001), LVEF had low predictive value for RVEF.
Why the study?
Does fast cine MR imaging in breath-hold technique accurately assess right ventricular volumes and ejection fraction in normal volunteers and cardiac patients?
Observational (n=377)
Does fast cine MR imaging in breath-hold technique accurately assess right ventricular volumes and ejection fraction in normal volunteers and cardiac patients?
Effect estimate: r = 0.55
p-value: p=<0.001
Fast cine MRI is a feasible method for routine assessment of right ventricular volumes and ejection fraction, demonstrating that RV dysfunction is common and not reliably predicted by LV dysfunction alone.
No takes yet. Share an insight, caveat, or question.
RV dysfunction may warrant separate assessment beyond LVEF; leaves open impact on outcomes and management.
Rominger et al. (1999) conducted an observational in Cardiac disease (CAD, VD, CM, CHD) (n=377). Fast cine MR imaging in breath-hold technique vs. Left ventricular evaluation was evaluated on Right ventricular ejection fraction (RVEF) abnormality and correlation with LVEF (r = 0.55, p=<0.001). Fast cine MR imaging showed reduced right ventricular ejection fraction in 31% of cardiac patients; while RVEF correlated with LVEF (r=0.55, P<0.001), LVEF had low predictive value for RVEF.
