In this exploratory analysis of 35 patients with ischemic cardiogenic shock, we evaluated the correlation between tricuspid regurgitation velocity (TRV) and pulmonary artery catheter-derived pressures. TRV correlated best with pulmonary artery mean pressure ( = 0.54,  = 0.0009), more than with systolic or diastolic pressures. A TRV threshold of 2.3 m/s identified mean pressure >25 mmHg with 81% sensitivity and 62% specificity. These findings suggest that TRV may serve as a non-invasive indicator of elevated pulmonary pressure in critically ill patients when invasive monitoring is unavailable. Further validation in larger, diverse cohorts is needed.
