Ba. Grishkin et al., ISOLATED RIGHT ATRIAL COMPRESSION - AS A LATE SEQUELA OF AORTIC-VALVEREPLACEMENT, Texas Heart Institute journal, 21(3), 1994, pp. 225-227
Isolated right atrial compression occurred 31 months after aortic valv
e replacement. Aortic bleeding contained by adjacent pericardium produ
ced a pseudoaneurysm and local atrial tamponade. Transthoracic echocar
diography could not distinguish the extracardiac hematoma from an intr
a-atrial thrombus, temporarily misleading investigators.
