Evaluation of the Contribution of the Ultrasound Tracking and the Positioning of the Distal End During the Implantation of Implantable Chamber or Long-lasting Venous Catheter

Given the increase in the number of PAC implants or long-term catheters, and the ease of access to cardiac ultrasound in the operating theaters, the investigator thought to use ultrasound to PAC or long-term catheters. The investigator considers cardiac echocardiography through its costal pathway to locate the correct positioning of the distal end of the catheter in a manner equivalent to the scopic locating with all the side effects of the irradiation and with Equivalent efficiency
