title: Echocardiographic assessment of pressure volume relations in heart failure and valvular heart disease: using imaging to understand physiology.
abstract: Pressure volume (PV) based analysis, using classic hemodynamic principles, has served as a basis for our understanding of cardiac physiology and disease states for decades. However, PV analysis has been restricted to primarily the basic research setting and for preclinical testing and has not be widely applied in part because of the invasive nature of the procedure and the expertise required to obtain adequate data using the conductance catheter. Development of single beat methodologies that rely on echocardiographic measurements of ventricular volume and Doppler and peripheral estimates of ventricular pressure and timing of the cardiac cycle has enabled broader application of PV analysis. This review explores the physiologic background, basic methodology, and recent and potential future applications of noninvasive PV analysis.
