“…Left atrial dilation on MRI has high predictive value when comparing PAH and left heart failure [30]. However, echocardiography underestimates cardiovascular magnetic resonance-derived left atrial volume [31]. This explains why echocardiographic left atrial dilation, though more frequently present in pulmonary venous hypertension, has insufficient discriminatory power as a single parameter [24,32].…”

Exclusion of pulmonary hypertension secondary to left-sided heart disease (left heart failure (LHF)) is pivotal in the diagnosis of pulmonary arterial hypertension (PAH). In case of doubt, invasive measurements are recommended. The aim of the present study was to investigate whether it is possible to diagnose LHF using noninvasive parameters in a population suspected of PAH. 300 PAH and 80 LHF patients attended our pulmonary hypertension clinic before August 2010, and were used to build the predictive model. 79 PAH and 55 LHF patients attended our clinic from August 2010, and were used for prospective validation.A medical history of left heart disease, S deflection in V1 plus R deflection in V6 in millimetres on ECG, and left atrial dilation or left valvular heart disease that is worse than mild on echocardiography were independent predictors of LHF. The derived risk score system showed good predictive characteristics: R 2 =0.66 and area under the curve 0.93. In patients with a risk score ⩾72, there is 100% certainty that the cause of pulmonary hypertension is LHF. Using this risk score system, the number of right heart catheterisations in LHF may be reduced by 20%.In a population referred under suspicion of PAH, a predictive model incorporating medical history, ECG and echocardiography data can diagnose LHF noninvasively in a substantial percentage of cases. @ERSpublications A risk score system can identify left-heart failure as alternative PH cause in patients suspected of PAH clinically http://ow.ly/JAIkR

“…18 Whitlock et al have also reported a significant underestimation of 2D-TTE-derived LAV estimation using similar methodology (biplane area length method) by transthoracic echocardiogram when compared with cardiac magnetic resonance. 19 This discrepancy has been proposed to be due to the foreshortening of the LA and limited spatial resolution at this level due to the significant distance of the left atrial roof from the transducer.…”
