To the Editor: Fedullo et al. (Nov. 15 issue)1 provide a concisereview of the pathophysiology, diagnosis, and surgical treatmentof chronic thromboembolic pulmonary hypertension. Because manyof my patients with this disorder have multiple medical problems,they are at high risk for complications from angiography andare not candidates for thromboendarterectomy. Could the authorscomment on the use of magnetic resonance angiography as a noninvasivediagnostic method2,3 and the use of anticoagulants, diuretics,and vasodilators for the treatment (albeit mainly symptomatic)of this disorder?
