However, this is an invasive tool, and noninvasive alternatives such as transthoracic echocardiography (TTE<\/jats:styled-content>) are preferable. Nonetheless, the correlation between measurements by TTE<\/jats:styled-content> and RHC<\/jats:styled-content> are debated. In this study, we prospectively examined the correlation between systolic and mean pulmonary artery pressures (sPAP<\/jats:styled-content> and mPAP<\/jats:styled-content>) measured by RHC<\/jats:styled-content> and TTE<\/jats:styled-content> in patients with hemodynamically significant rheumatic mitral stenosis (MS<\/jats:styled-content>).<\/jats:p><\/jats:sec>Material and Methods<\/jats:title>Three hundred patients with hemodynamically significant MS<\/jats:styled-content> undergoing TTE<\/jats:styled-content> who were scheduled to undergo RHC<\/jats:styled-content> within 24\u00a0hours were analyzed. PAP<\/jats:styled-content> measurements were taken for all patients by RHC<\/jats:styled-content> (sPAPRHC<\/jats:sub><\/jats:styled-content>, mPAPRHC<\/jats:sub><\/jats:styled-content>). Maximum velocity of tricuspid regurgitation (TR<\/jats:styled-content>) jet obtained by continuous\u2010wave Doppler with adding right atrial (RA<\/jats:styled-content>) pressure was used for measuring sPAP<\/jats:styled-content> by TTE<\/jats:styled-content> (sPAPTRV<\/jats:sub><\/jats:styled-content>max<\/jats:sub>). Mean PAP<\/jats:styled-content> was measured using either pulmonary artery acceleration time (mPAPPAAT<\/jats:sub><\/jats:styled-content>) method or by adding RA<\/jats:styled-content> pressure to velocity\u2013time integral of TR<\/jats:styled-content> jet (mPAPTRVTI<\/jats:sub><\/jats:styled-content>).<\/jats:p><\/jats:sec>Results<\/jats:title>A good correlation between sPAPRHC<\/jats:sub><\/jats:styled-content> and sPAPTRV<\/jats:sub><\/jats:styled-content>max<\/jats:sub> (r\u00a0=\u00a00.89, P\u00a0<\u00a00.001), between mPAPRHC<\/jats:sub><\/jats:styled-content> and mPAPPAAT<\/jats:sub><\/jats:styled-content> (r\u00a0=\u00a00.9, P\u00a0<\u00a00.001), and between mPAPRHC<\/jats:sub><\/jats:styled-content> and mPAPTRVTI<\/jats:sub><\/jats:styled-content> (r\u00a0=\u00a00.92, P\u00a0<\u00a00.001) was found. Sensitivity and specificity of sPAPTRV<\/jats:sub><\/jats:styled-content>max<\/jats:sub> in detecting pulmonary hypertension (PH<\/jats:styled-content>) were 92.8% and 86.6% and of
