Accurate assessment of right ventricular (RV) function has received a growing attention. Pressure–volume (PV) loop analysis is the gold standard method for evaluating RV function; however, it is not widely employed because of 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 three‐dimensional 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.
