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.
We report a case of Aspergillus sp. mural or nonvalvular endocarditis, which was diagnosed by transesophageal echocardiography (TEE) as a vegetation attached to the anterolateral papillary muscle of the left ventricle. Mural endocarditis is often missed by transthoracic echocardiography (TTE) as was the case with this patient. TEE easily identified the vegetation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
