Clinical significance of pericardial effusion after heart transplantation.
Fifty-two consecutive patients who underwent orthotopic heart transplantation at our institution were evaluated by two-dimensional (2D) echocardiography at frequent intervals for 12 weeks after transplantation and at three monthly intervals for 1 year. Thirty-eight of 52 patients had adequate 2D echocardiograms and comprised the retrospective study group. Pericardial effusion was documented in 15 of 38 patients (40%). Pericardial effusion was moderate in two (5%) and small in seven patients (18%). Large pericardial effusion was demonstrated in six of 38 patients (16%). Three of 38 patients (8%) developed cardiac tamponade manifested by hypotension in the presence of a large pericardial effusion. The diagnosis of cardiac tamponade was aided by 2D echocardiography leading to prompt pericardiocentesis. The presence of pericardial effusion in patients after their transplantation did not demonstrate independent correlation with chest tube output after operation, cyclosporine therapy, acute rejection, level of blood urea nitrogen (BUN), infection or preoperative diagnosis of idiopathic dilated cardiomyopathy. The presence of cyclosporine therapy, acute rejection, and a preoperative diagnosis of idiopathic dilated cardiomyopathy, however, yielded an 86% probability of having pericardial effusion. Follow-up 2D echocardiograms obtained 301 +/- 106 days after transplantation were available in 25 patients. Fifteen patients (60%) had no pericardial effusion present on either the initial or follow-up 2D echocardiogram. The majority of cases of the pericardial effusion present on initial or follow-up echocardiograms were resolving on the follow-up study.(ABSTRACT TRUNCATED AT 250 WORDS)
