title: Experimental and first clinical experiences with implantable ultrasonic Doppler probes for postoperative bypass control after coronary surgery.
abstract: Concerning postoperative bypass hemodynamics after open heart surgery only few data are known. With this new implantable doppler probe we developed an easy-to-use bedside method for monitoring postoperative bypass function after coronary artery bypass grafting. The accuracy of our method is shown by using a circulation model and by animal studies. Furthermore first clinical data are shown which support our conclusion of having found a sensitive method for monitoring small vessels' hemodynamics.
