Deficient Surrounding Rims in Patients Undergoing Transcatheter Atrial Septal Defect Closure.
The influence of deficient rims surrounding atrial septal defects (ASDs) in patients undergoing transcatheter closure has yet to be clarified. The aim of this study was to assess the influence of a deficient surrounding rim on the procedural success and clinical outcome of transcatheter ASD closure using an Amplatzer septal occluder. ⋯ In patients with ASDs with multiple rim deficiencies as determined by transesophageal echocardiography, successful transcatheter ASD closure using Amplatzer septal occluders is more difficult to accomplish. However, if closure is successful, rim deficiencies rarely affect intermediate-term outcomes.

Serial Echocardiographic Assessment of Left Ventricular Filling Pressure and Remodeling among ST-Segment Elevation Myocardial Infarction Patients Treated by Primary Percutaneous Intervention.
Acute myocardial infarction and remodeling of the left ventricle is associated with significant changes in systolic and diastolic echocardiographic derived indices. The investigators have tried to determine whether persistence of increased ratio of transmitral flow velocity (E) to early mitral annulus velocity (e'), signifying increased cardiac filling pressure, is associated with left ventricular (LV) remodeling and increased chamber size among patients presenting with ST-segment elevation myocardial infarction, who underwent successful reperfusion with primary percutaneous coronary intervention. ⋯ Among patients with ST-segment elevation myocardial infarctions undergoing primary percutaneous coronary intervention, early and persistent elevation of the E/septal e' ratio may be associated with LV remodeling.
