Bech-Hanssen et al reported the Right Ventricular Dysfunction (RVD) score for evaluating a patient with left ventricular dysfunction. The score correlates with the hemodynamic profile for hypoperfusion and congestion. The authors are from the Sahlgrenska University Hospital and University of Gothenburg.
Patient selection: left ventricular dysfunction
Parameters:
(1) systolic pulmonary artery pressure in mm Hg (measure of right ventricular afterload)
(2) right ventricular end diastolic area divided by body surface area in square meters (measure of right ventricular size in square cm divided by square meters
(3) tricuspid annular plane systolic excursion (TAPSE) in mm
(4) grade of tricuspid regurgitation
(5) inferior vena cava collapsibility in percent (measure of right atrial pressure)
(6) sex
