The Nyquist limit of the color Doppler system has been displayed near the color bar as 60 cm\/s. The TR jet envelope is incomplete in most cycles, indicating that it is a mild TR. Calculated right ventricular systolic pressure (RVSP) is 31.7 mm Hg, assuming a right atrial pressure of 10 mm Hg, indicating mild (borderline) pulmonary hypertension. Systolic pressure above 30 mm Hg and mean pressure above 20 mm Hg in the pulmonary artery is usually taken as elevated.<\/p>\n<figure id=\"attachment_25654\" aria-describedby=\"caption-attachment-25654\" style=\"width: 390px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-25654 size-full\" src=\"https:\/\/johnsonfrancis.org\/professional\/wp-content\/uploads\/2009\/10\/Subcostal-view.jpg\" alt=\"Subcostal view demonstrating the interatrial septum\" width=\"390\" height=\"401\"><figcaption id=\"caption-attachment-25654\" class=\"wp-caption-text\">Subcostal view demonstrating the interatrial septum<\/figcaption><\/figure>\n<p>Subcostal view demonstrating the interatrial septum (IAS) and the liver above the heart.
