Tricuspid annular motion and velocity as a parameter for right ventricular function in patients with inferior myocardial infarction

ABSTRACT

The amplitude of tricuspid annular motion was significantly lower in patients with inferior MI compared with patients with anterior MI and healthy individuals. Compared with patients without RV infarction, the tricuspid annular motions was significantly lower in patients with RV infarction. In patients with KV infarction, the systolic velocity peak early diastolic velocity and E/L ratio measured at the KV free wall showed a high significant reduction when compared with other groups. The peak systolic and peak early diastolic velocities of the inter ventricular septum in the infarction groups were significantly lower compared with that in healthy individuals, the decreased systolic velocity was more pronounced in patients with RV infarction. Tricuspid annular motion and tricuspid annular velocity can be used as a simple, rapid and noninvasive tool for assessing RV function after inferior myocardial infarction and to detect and confirm the diagnosis of RV infarction
