Key result
In patients with pulmonary hypertension, fractional longitudinal right ventricular motion was significantly greater than fractional transverse motion (mean difference 2%).
Why the study?
Does cardiovascular magnetic resonance imaging-derived longitudinal and transverse right ventricular motion correlate with global right ventricular function and ventricular interaction in patients with pulmonary hypertension?
Cross-Sectional (n=165)
No
Does cardiovascular magnetic resonance imaging-derived longitudinal and transverse right ventricular motion correlate with global right ventricular function and ventricular interaction in patients with pulmonary hypertension?
Mean Difference: 2 (95% CI 0.3–3.8)
Absolute Event Rate: 15.2% vs 13.2%
p-value: p=0.002
In patients with pulmonary hypertension, longitudinal right ventricular motion is primarily associated with global pump function, whereas transverse motion is independently influenced by ventricular interaction.
No takes yet. Share an insight, caveat, or question.
Longitudinal RV motion exceeds transverse in PH; supports distinct roles in global function versus interaction but leaves open clinical utility.
Swift et al. (2015) conducted a cross-sectional in Pulmonary hypertension (n=165). Pulmonary hypertension vs. No pulmonary hypertension was evaluated on Difference between fractional longitudinal motion (f-TAAD) and fractional transverse motion (f-SFD) in patients with pulmonary hypertension (MD 2%, 95% CI 0.3-3.8, p=0.002). In patients with pulmonary hypertension, fractional longitudinal right ventricular motion was significantly greater than fractional transverse motion (mean difference 2%).
