Key result
Bidimensional CMR measurement of TAPSE <18 mm was strongly associated with an increased risk of death in patients with pulmonary arterial hypertension (HR 4.8; 95% CI 2.0-11.3; P=0.005).
Why the study?
Do bidimensional CMR measurements of RV function predict survival and reduce analysis time compared to volumetric measures in patients with PAH?
Observational (n=67)

Hazard Ratio: 4.8 (95% CI 2–11.3)
p-value: p=0.005
Bidimensional CMR measurements of RV function, such as TAPSE, are faster to obtain than volumetric measures and strongly predict survival in patients with PAH.

2D RV measures may expedite CMR assessment in PAH; leaves open prospective validation of survival prediction equivalence.
Corona‐Villalobos et al. (2015) conducted an observational in Pulmonary arterial hypertension (n=67). Bidimensional measurements of right ventricular function by CMR (e.g., TAPSE <18 mm) vs. Volumetric measures by CMR / TAPSE ≥18 mm was evaluated on Risk of death (HR 4.8, 95% CI 2.0-11.3, p=0.005). Bidimensional CMR measurement of TAPSE <18 mm was strongly associated with an increased risk of death in patients with pulmonary arterial hypertension (HR 4.8; 95% CI 2.0-11.3; P=0.005).
