Typical diameter measurements are less than 36 mm and the distal area of the long axis diastol in the 4 distal chamber position is more often used. to more accurately assess the severity of the RV amplification It is recommended to use the ratio of the tip area. RV ventricular pressure versus LV ventricular systolic pressure, therefore excluding individual heart size differences. An increase in this indicator greater than 0.6 indicates a significant enlargement of the pancreas.
