“…In the Testani and coworkers' investigation, 75.4% were discrepant by at least 10% (65% overestimation and 35% underestimation), and 54.4% were discrepant by at least 20% (72% overestimation and 28% underestimation), 19 while in the exercise study performed in patients with connective tissue disease, ECHO underestimated PASP in 37% of patients during maximum exercise. 18 Among the 1364 patients in the REVEAL cohort who had available data for both RHC-measured PASP and ECHO-measured PASP, 69.8% had ECHO PASP values that were discrepant by at least 10%, and 44.4% were discrepant by at least 20% (in both cases, evenly divided between overestimation and underestimation). Variability in the proportion of overestimation and underestimation in these studies may be due to differences in study populations.…”

“…Tatsächlich ist dieser Zustand bei SSc-Patienten nicht selten, und kommt abhängig von den Untersuchungskriterien bei etwa 30-60% der Patienten vor [29][30][31][32][33][34]. Eine Studie konnte die Ergebnisse aus nichtinvasiven Methoden auch mittels Rechtsherzkatheter bestätigen [35]. Die invasiven Daten zeigten aber auch, dass in etwa 30% der Fälle ein PAWP-Anstieg ursächlich für den pulmonalen Druckanstieg ist.…”

“…In the study by Kovacs et al, there was no significant difference in SPAP between exercise Doppler echocardiography and right heart catheterisation at increasing stages of semi-supine bicycle exercise (13). In a more recent study by Claessen et al, both MPAP and SPAP from echocardiography had good correlations with exercise cardiac magnetic resonance imaging combined with simultaneous invasive pressure registration (12).…”

“…Our group has previously shown that exercise SPAP is feasible and reproducible in high-volume Heart Valve Clinics with dedicated imaging protocols and skilled operators. In patients with secondary mitral regurgitation, we could achieve a feasibility rate of 94% using semi-supine bicycle ergometer for SPAP measurement, without the need for contrast administration (13).…”
