| Abstract: | Transthoracic echocardiography (TTE) is frequently performed in patients with suspected acute pulmonary embolism (APE) to search for right ventricular (RV) pressure overload. We prospectively assessed the diagnostic value of a new Doppler echocardiographic sign of APE based on the disturbed RV ejection pattern ("60/60 sign") and compared its diagnostic performances with that of the presence of RV pressure overload, as well as with "McConnell sign" based on RV regional wall motion abnormalities. We assessed 100 consecutive patients with clinical suspicion of APE, including those with previous cardiorespiratory diseases. After TTE, all of the patients underwent reference diagnostic tests for APE. The 60/60 sign required RV acceleration time of
