Right ventricular pressure-volume loop produced with simultaneous
application of three-dimensional echocardiography and high-fidelity
micromanometry in a patient with pulmonary arterial hypertension
Abstract
Accurate assessment of right ventricular (RV) function is drawing a
growing attention. Pressure-volume (PV) loop analysis is the gold
standard method for evaluating RV function; however, it is not widely
employed due to its invasive nature and complexity. The present report
is the first to have drawn a RV PV loop in a patient with pulmonary
hypertension, with a simultaneous recording of RV pressure and volume
using high fidelity micromanometry and 3D echocardiography. This allows
for less invasive and simple assessment of RV function, potentially
promoting better understanding and management of pulmonary hypertension
and other cardiovascular diseases.
