2D assessments during preoperative TEE for MR. Panel A: The mitral valve annulus is dilated (5.0 cm). Panel B: Tricuspid annulus should be measured as this may predict postoperative functional tricuspid regurgitation. In addition, the severity of tricuspid regurgitation should be assessed. Panel C: Maximum TR velocity should be measured to determine pulmonary artery systolic pressure. This is sometimes challenging on TEE and maybe better appreciated on transthoracic imaging.
