To the Editor As members of the guideline committee sponsored by the American Thoracic Society on the diagnosis and treatment of pulmonary hypertension in patients with SCD,1 we would like to emphasize several important differences between our guidelines and the pulmonary hypertension recommendations made by Dr Yawn and colleagues.2 We concur that an echocardiogram is an essential part of the evaluation of patients with SCD and unexplained dyspnea and that right heart catheterization is required for diagnosis of pulmonary hypertension.
