[Development of echocardiographic and Doppler parameters after orthotopic cardiac transplantation, except during rejection periods]. 
The aim of this study was to evaluate spontaneous changes of Doppler and echocardiographic parameters of cardiac transplants in the absence of rejection.  Based on 258 recordings representing the follow up of 30 patients after orthotopic cardiac transplantation in the absence of histological signs of rejection on biopsy within 24 hours, we tried to define: the evolution of these parameters from the first postoperative week to after the 30th month (average 12 months); the Doppler echocardiographic values of "normal" transplants: the values observed one year after surgery were compared with a control group age-matched to the donors.(ABSTRACT TRUNCATED AT 250 WORDS)
