Key result
The echocardiographic RVD/T(peak) ratio at a cutoff of 22 cm/s predicted the presence of pulmonary hypertension with 80% sensitivity and 83% specificity, regardless of right ventricular dysfunction.
Why the study?
Does the RVD/T(peak) ratio accurately predict the presence of pulmonary hypertension in patients?
Observational (n=108)
Does the RVD/T(peak) ratio accurately predict the presence of pulmonary hypertension in patients?
Effect estimate: 80% sensitivity and 83% specificity
The RVD/T(peak) ratio is a useful echocardiographic parameter for predicting pulmonary hypertension, independent of tricuspid regurgitation and right ventricular dysfunction.

May aid non-invasive PH detection without TR; leaves open validation in larger prospective cohorts.
McLean et al. (2006) conducted an observational in Pulmonary hypertension (n=108). Echocardiographic RVD/T(peak) ratio was evaluated on Presence of pulmonary hypertension (80% sensitivity and 83% specificity). The echocardiographic RVD/T(peak) ratio at a cutoff of 22 cm/s predicted the presence of pulmonary hypertension with 80% sensitivity and 83% specificity, regardless of right ventricular dysfunction.
