Peripheral venous contrast echocardiography. A study of a new technique of injection in vitro and in vivo.
A new technique of peripheral venous contrast echocardiography is described which uses a special type of injection catheter to achieve a much greater density of image of the cardiac cavities. The multi-hole catheter gave consistently better results than the conventional single hole catheter under trials both in vitro and vivo.
