Pulmonary valve regurgitation (PR) may be classified according to etiology of the regurgitant flow, severity of the disease and chronicity. Based on the etiology of the regurgitant flow, PR may be classified into primary and secondary/ functional types. The severity of the disease may classify into mild, moderate and severe disease. New York Heart Association's (NYHA) functional classification helps to gauge the severity of the heart failure which is a complication of PR. The severity of PR can be assessed by utilizing the American Heart Association and American College of Cardiology (AHA/ACC) staging of valvular heart disease (VHD).
