Case Reports
Echocardiographic identification of intrapericardial fibrous strands in acute pericarditis with pericardial effusion.
In three cases of acute pericarditis with pericardial effusion, the presence of fibrous strands within the fluid-filled pericardial cavity was demonstrated by M-mode and cross-sectional echocardiography. Pericardiocentesis proved difficult in all three. No patient progressed to constrictive pericarditis.
