Lemarchand et al 1 address an everyday question in the echocardiography laboratories about the reliability of systolic pulmonary artery pressure (sPAP) estimation in cases of severe tricuspid regurgitation (TR). It is concluded that sPAP is underestimated in cases of massive or torrential TR (TR-V), high right atrial (RA) pressure and ‘V-wave cut-off’sign on echocardiography. The applicability of the simplified Bernoulli equation in patients with TR-V for sPAP estimation is unclear and has not been adequately studied. While some authors alert that sPAP may be underestimated,2 others argue …
