Optimizing Preclinical PV Loop Techniques and Analysis in Mice

Web video URL

This is a useful webinar for preclinical researchers interested in getting started with Pressure-Volume acquisition and analysis, or those already using PV Loops who may benefit from tips on increasing throughout and experimental capacity.


During this session, Dr Daniel Donner and Dr Aascha Brown from the Baker Institute’s Preclinical Cardiology Microsurgery and Imaging Platform will provide best practice advice for Pressure-Volume catheterization in mice using the combined ADInstruments and Millar system. A complete walkthrough will be provided, from equipment lists, connection and setup; through to an introduction to the Labchart workflow for PV and how to optimize workflow from acquisition of PV Loops to how to analyze them too.

The Baker Insititute's Preclinical Cardiology Microsurgery and Imaging Platform specialize in myocardial ischemia-reperfusion models, novel cardiac arrest,  and aortic constriction models for preclinical trials. This webinar includes a step-by-step surgical procedure using the carotid N-S approach (with short accompanying video) using a Millar SPR-839 1.4F with a mouse model.

Key Topics:   

  • Recommended equipment list: For surgical procedures in mouse model
  • Importance of using PV Loops: A gold standard approach in hemodynamic studies
  • Introduction to PV assessments: Including compliance and inotropy / interpreting the loop
  • Surgical procedure setup: Including preparation tips, equipment setup and connection, overview of the MPVS interface, channel setup, introduction to the PV loop and workflow setup in LabChart 8.
  • Surgical Procedure Walkthrough: Including overview of procedural steps, carotid isolation and cannulation, supporting surgical video footage
  • Post Surgery Calibrations: Walkthrough of cuvette, saline, baseline and alpha calibration with tips for efficiency to support throughput. 
  • Overview of occlusions analysis 
  • Further calibration advice: The importance of SV/CO calibration on conductance measurements with examples of data variance
