BACKGROUND: Chronic pulmonary hypertension (CPHT) has a great impact on both right-ventricular (RV) systolic and diastolic properties and the assessment of those properties is not always feasible by traditional echocardiographic examination. Doppler tissue imaging (DTI) interrogation of the tricuspid annulus (TA) identifies the pattern of TA motion (TAM) and can help to assess RV function when other methods are not feasible.
AIMS: To determine RV systolic and diastolic function in patients with CPHT using DTI parameters of the TA.
METHODS: Eighty-seven patients with CPHT and 90 normal controls were studied. DTI parameters were measured including early diastolic, late diastolic and systolic velocities and time velocity integrals (TVI) of the TAM at both its lateral and medial aspect.
RESULTS: Early diastolic and systolic velocities, the ratio of early to late diastolic velocities and TVI of TAM at both lateral and medial aspects were significantly decreased in patients with CPHT compared to controls. No significant differences were seen in late diastolic velocities and TVI in both groups. Systolic velocity of the TAM at both its lateral and medial aspects significantly correlated with RV systolic function as measured by fractional RV area change.
CONCLUSIONS: DTI of the TAM can be used to assess RV systolic and diastolic properties in patients with CPHT.
