Use of Handheld Ultrasound to Estimate Right Atrial Pressure in a Pulmonary Hypertension Clinic.

Point-of-care ultrasonography is an invaluable asset for inpatient decision-making. Whether handheld ultrasound can be used in the outpatient management of pulmonary hypertension is unknown. We investigated whether a handheld ultrasound estimate of right atrial pressure correlates with B-type natriuretic peptide (BNP) and clinical outcome over time in outpatients with pulmonary hypertension.
