Why the study?
Diagnostic flowcharts for left ventricular filling pressures have limited value when surrogate parameters like maximal tricuspid regurgitation velocity are elevated for other reasons, prompting a comparison of 2009 and 2016 guideline accuracy in pulmonary hypertension.
Do the 2016 guideline recommendations improve the accuracy of estimating left ventricular filling pressures compared to the 2009 recommendations in patients with pulmonary hypertension?
Population
63 patients with PH from 101 consecutive patients undergoing RHC and TTE for suspected PH
Comparison
2016 guideline recommendations vs 2009 guideline recommendations
Design
Diagnostic accuracy study of consecutive patients

Supports 2016 recommendations for diastolic assessment in pulmonary hypertension; hypothesis-generating and requires prospective validation.
Do the 2016 guideline recommendations improve the accuracy of estimating left ventricular filling pressures compared to the 2009 recommendations in patients with pulmonary hypertension?
The 2016 guideline recommendations for echocardiographic evaluation of diastolic function are superior to the 2009 recommendations for estimating left ventricular filling pressures in patients with pulmonary hypertension.
