Figure 1.
Structure of the PressureWire Certus and fluoroscopic images of the pressure wire sited in the left ventricular (LV) cavity during an implant. The hydrophilic wire is 0.014 inches in diameter and has a radio-opaque sensor at the tip capable of measuring LV dP/dtmax when positioned in the LV cavity. The wire is connected to a RadiAnalyzer Xpress console (not pictured), which has been loaded with PhysioMon software (all Abbott Medical, St Paul, MN). The fluoroscopic images show the wire positioned in the LV cavity during a balloon occlusive venogram of the coronary sinus (in left anterior oblique) and the final LV lead position.
