“…However, FS is affected by loading conditions, thus it is strictly a measurement of LV function rather than a measurement of contractility5. Two‐dimensional tissue tracking (2DTT) is a novel echocardiographic technique, which was developed as an assessment method for myocardial function11, 12, 13, 14. In human, its clinical applications include assessment of coronary artery disease, myocardial infarction and various types of cardiomyopathies11, 12, 13.…”

BackgroundClosure of PDA can be associated with echocardiographic changes including deterioration of LV systolic function. Although PDA is commonly encountered in dogs, few comprehensive reports of echocardiographic changes in dogs with PDA closure are available.ObjectivesTo evaluate the short‐term echocardiographic changes observed after PDA closure in dogs using strain analysis.AnimalsSeventeen client‐owned dogs with left‐to‐right PDA.MethodsEchocardiographic evaluations, including standard echocardiography and two‐dimensional tissue tracking (2DTT), were performed before and within 3 days of PDA closure.ResultsPreclosure examination showed LV and left atrial dilatation indicating volume overload as a result of PDA. Closure of PDA resulted in significant reduction of LVIDd (<.0001) and LA/Ao (0.01) without change in LVIDs, suggestive of decreased preload. Postclosure LV systolic dysfunction was observed with significant decreased in FS (<.0001) and strain values (P = .0039 for radial strains, P = .0005 for circumferential strains). Additionally, significant LV dyssynchrony (P = .0162) was observed after closure of PDA.Conclusions and Clinical ImportanceClosure of PDA resulted in decreased preload as a result of alleviation of LV volume overload, which in turn caused transient deterioration of LV systolic function. Additionally, this study demonstrated that strain analysis is load dependent. Therefore, care should be taken when interpreting strain measurements as an indicator of LV systolic function.

IMPORTANCE Albuminuria, as measured by single urine albumin-to-creatinine ratio (UACR) levels, is associated with cardiac remodeling and adverse clinical outcomes. The longitudinal patterns of change in UACR through young adulthood and their associations with myocardial structure and function later in life remain unclear. OBJECTIVE To describe the trajectory of albuminuria as measured by UACR across a 20-year span and evaluate the association of albuminuria trajectory with echocardiographic indices of structure and function in middle age. DESIGN, SETTING, AND PARTICIPANTS In the Coronary Artery Risk Development in Young Adults (CARDIA) study, a prospective cohort of black and white participants
