PV Loop Research Applications
Pressure-volume (PV) loop studies provide researchers with comprehensive, load-independent data regarding normal and diseased conditions of the heart. With an in-depth view of the complete cardiac cycle, insights can be gained in heart failure models, valvular disease, and basic cardiovascular research. With over 30 different hemodynamic parameters, PV loop data can easily advance research studies to the next level.
PV Loop Studies Deliver Direct
Known as the gold-standard method for measuring direct, real-time, complete cardiac function, Millar's pressure-volume (PV) loop system delivers instant cardiovascular function feedback. PV loop studies provide researchers with comprehensive independent data regarding normal and diseased conditions of the heart by generating the characteristic left or right ventricular pressure-volume (PV) loops.
A single PV loop is created by plotting pressure and volume signals against each other in real time, with one loop representing the complete cardiac cycle. PV loops provide instant cardiovascular function feedback based on its morphology, position, and timing. Only left or right ventricular PV loops can provide beat-to-beat and full diastolic analysis from a single, minimally invasive catheter. Millar offers pressure-volume loop technology for both research and clinical applications.
Cutting-edge PV Loop studies have a wide variety of research applications in both large and small animal models, including:
- Basic cardiovascular research
- Stem cell studies
- LVAD evaluation
- Cardiac hypertrophy
- Heart failure
- Cardiovascular remodeling
- LV/RV coupling
- Valvular assessment
- Pharmacology (rapid drug screening)
- Cardiac resynchronization therapy
- Surgical interventions
- Ischemia/reperfusion studies
- Vascular occlusions

PV Loops: Mouse to Man
Dr. Navin Kapur, Assistant Professor and Assistant Director of the Interventional Cardiology Center at Tufts Medical Center, discusses his experience utilizing PV loop data in cardiovascular applications from mouse to man. Additionally, Dr. Kapur provides perspective on how PV Loops can be used as a tool for the interventional cardiologist and during the evaluation of advanced heart failure.
