Guidelines for Assessing Ventricular Pressure-Volume Relationships in Rodents | AJP-Heart and Circulatory Physiology Podcast In this episode, Deputy Editor Dr. Zamaneh Kassiri (University of Alberta) interviews authors Dr. Oliver H. Wearing (University of British Columbia), Dr. Naomi C. Chesler (University of California Irvine), Dr. Mitchel J. Colebank (University of South Carolina), Dr. Timothy A. Hacker (University of Wisconsin-Madison), Dr. John N. Lorenz (University of Cincinnati), and Dr. Christopher R. West (University of British Columbia) about their new Guidelines in Cardiovascular Research article. This must-read Guidelines article provides a thorough overview of ventricular pressure-volume (PV) measurements in the mouse heart. PV measurements are an invasive method for assessment of heart function, and if done correctly, can provide researchers with valuable information about heart hemodynamics and the relationship between changes in ventricular pressure and volume during a cardiac cycle. The authors discuss PV measurements as the gold standard for assessing cardiac in vivo function. How do PV measurements differ from, and provide a complement to, echocardiography measurements? Listen and find out more.   Oliver H. Wearing, Naomi C. Chesler, Mitchel J. Colebank, Timothy A. Hacker, John N. Lorenz, Jeremy A. Simpson, and Christopher R.
