PV Loop Catheters

CD Leycom’s pressure-volume loop catheters provide real-time ventricular PV loop data, enabling a complete assessment of cardiac function from a single catheterization.

  • Compatible with both the Inca® (clinical) and Sigma-M© (research) PV loop systems
  • Available in 4-French and 7-French sizes
  • Minimized signal drift with full-bridge, solid-state sensors

These catheter’s utilize high-fidelity sensors to provide real-time, beat-to-beat PV loop measures originated from the Baan’s equation principle.

PV Loop Catheter
4-French PV Loop Catheter
  • 4F pigtail catheter 12 electrodes; 1 pressure sensor between electrodes 5 and 6
  • No lumen; typically used with an appropriate sized introducer sheath for delivery
  • Electrode spacing options at 6 mm and 10 mm between the electrodes
7-French PV Loop Catheter
  • 7F pigtail catheter with 12 electrodes; 1 pressure sensor between electrodes 5 and 6
  • 0.025” lumen; typically used with 0.025″ exchange-length guide wire for delivery
  • Electrode spacing options at 8 mm, 10 mm and 12 mm between the electrodes
PV Loop Catheter Preparation

Ideal positioning of the 7F pressure-volume loop catheter in the left ventricle.

Select the best catheter

Optimal pressure-volume recordings require the use of the correct catheter. Follow the guide to the right to determine which catheter to use for the different ventricular sizes.

Guides for Catheter Selection

CD Leycom catheter sizing guide

The catheter length should match the ventricular long axis (as measured by MRI and/or echocardiography).

Minimum length (mm): (3 x L) + (2 x La) + 10.0 (pigtail)

Maximum length (mm): (7 x L) + (2 x La) + 10.0 (pigtail)

* = Driving electrodes. The proximal driving electrodes may be positioned above the aortic valve.
L = Electrode spacing
La = Spacing (3 mm) between the driving electrodes.
