Factors associated with mitral annular systolic and diastolic velocities in healthy adults.
Measurements of systolic mitral annular velocity (S'), early diastolic mitral annular velocity (E'), and late diastolic mitral annular velocity (A') are used to assess left ventricular (LV) function. ⋯ S', E', and A' are not only of different magnitudes at the septal and lateral sites, but are not closely correlated. There are relationships between annular velocities and body size, HR, blood pressure, and LV mass that differ between the septal and lateral annulus, providing a possible explanation for the lack of close correlation in these velocities and suggesting that these variables may need to be considered when interpreting annular velocities.

Right ventricular strain in pulmonary embolism by Doppler tissue echocardiography.
For patients with submassive pulmonary embolism, failure of the right ventricle can often be visualized by 2-dimensional echocardiography. We used strain analysis to demonstrate changes in the regional right ventricular free wall performance during the acute and recovery stages of pulmonary embolism.

Case ReportsLeft atrial hematoma complicating inferior myocardial infarction.
Intramyocardial dissecting hematoma after myocardial infarction is a rare condition. Previous reports have documented that these hematomas form almost exclusively in the myocardium adjacent to the culprit coronary lesion. We report a case of coexistent intramyocardial dissecting hematoma and ventricular rupture that arose as a consequence of a distal right coronary artery occlusion. Unusually, there was a very long dissection plane, which crossed the atrioventricular groove, with the hematoma manifesting on the opposite side of the heart (left atrium) to the infarcted myocardium (inferior wall).
