Abstract

Acute coronary syndromes (ACSs) present most frequently with chest pain, but angina equivalents such as dyspnea, diaphoresis, and fatigue are not uncommon. Atypical presentations are especially seen in women, the elderly, and diabetics. Cardiac evaluation using a transthoracic echocardiogram is almost always done before or immediately after someone undergoes left heart catheterization for ACS. It provides information valuable information regarding wall motion, left ventricular systolic function, diastolic function, right ventricular involvement, pulmonary pressures, incidental valvular disease, pericardial fluid, or any other unsuspected abnormality. We describe a novel case where an atypical presentation of ACS was suspected based on the lack of intravenous contrast administered, to enhance endocardial border resolution. The use of contrast during echocardiography has been used during stress protocols to assess microcirculation during perfusion assessment studies. However, we described a reduced uptake during the acquisition of resting myocardial echocardiogram images and it was very useful to direct therapy. [ABSTRACT FROM AUTHOR]

24. True relationship between tricuspid annular motion and velocity displacement components: Potential role in assessing right ventricular decoupling.

Abstract

Background: Although measures of longitudinal displacement of the tricuspid annulus measured by M‐mode as tricuspid annular systolic plane excursion (TAPSE) and systolic velocity by tissue Doppler imaging (TA TDI s) are routinely used for assessment of right ventricular (RV) systolic function; these measures describe different phenomena and should not be used interchangeably. Methods: Previously published data was used to determine the individual relationship between TAPSE and TA TDI s with increasing pulmonary artery systolic pressures (PASP). Results: In this retrospective analysis, 488 patients were divided into 2 groups based on TAPSE (Group 1: <1.8 cm and Group 2: ≥1.8 cm). A robust correlation (R =.79) between TAPSE and TA TDI s noted for the entire population. However, a statistically lower correlation (R =.43) was seen between Group 1 and Group 2 (R =.65; p <.0047). With increasing pulmonary pressures, only PASP (p <.0001) and TA TDI s (p <.0001) discriminated between low and normal TAPSE/PASP values. Suggesting that a TA TDI s/PASP ratio would be most useful than TAPSE/PASP with a specificity of 80%. Conclusions: Significant differences exist between TAPSE and TA TDI s, particularly at low TAPSE values with increased PASP, were uncoupling occurs. Our data seems to suggest that TA TDI s/PASP would be most useful than TAPSE/PASP ratio. Future studies should address, if abnormalities in the material properties along the RV free wall account for these differences seen between TAPSE and TA TDI s. [ABSTRACT FROM AUTHOR]
