A valved compressible state of the art Dacron shunt is sutured to the left atrium and to the descending thoracic aorta. One ferromagnetic and one diamagnetic shunt compression plate is positioned on one side of the shunt with the two plates in opposing relationship. A state of the art electromagnet and synchronizing mechanism exteriorly of the body cyclically, in accordance with the patient's QRS complex, generates a pulsating magnetic field which drives the ferromagnetic plate toward the diamagnetic plate, thereby cyclically compressing the shunt during diastole and giving assistance to the left ventricle of the heart. |
