Doppler assessment of right ventricular filling in a normal population. Comparison with left ventricular filling dynamics.
Why the study?
How do right ventricular filling dynamics change with age and compare to left ventricular filling in normal subjects?
Population
50 normal volunteers (23 males and 27 females) with an age range of 5-66 years.
Design
Cross-sectional

Implication
Age-related RV filling changes parallel LV patterns; extends prior observations but leaves open validation for age-specific norms.
Structured PICO
How do right ventricular filling dynamics change with age and compare to left ventricular filling in normal subjects?
P
Population
50 normal volunteers (23 males and 27 females) with an age range of 5-66 years.
I
Intervention
Pulsed Doppler echocardiographic studies at the tricuspid and mitral anuli
O
Outcome
Right ventricular filling dynamics (peak early filling velocity, peak late velocity, late/early ratio) and their relation to age, heart rate, respiration, and left ventricular fillingsurrogate
Right ventricular filling dynamics change significantly with age, heart rate, and respiration, and correlate with left ventricular filling, highlighting the need to account for these factors in echocardiographic assessments.
