Echocardiography Unreliable in Detecting Pulmonary Ailments.
KAMUELA, HAWAII -- Echocardiography miclsassfied pulmonary artery pressure in 37% of pregnant patients with suspected pulmonary hypertension in one study, Dr. Kelly Robinson reported.
The noninvasive test misclassified 8 of 27 patients with heart disease as having pulmonary hypertension when in fact they had normal pulmonary artery pressure on catheterization. It also classified as normal two patients who were diagnosed with pulmonary hypertension when right heart catheterization was performed, she said at the annual meeting of the Pacific Coast Obstetrical and Gynecological Society.
The retrospective review examined charts for pregnant patients with cardiac disease who received both echocardiography and cardiac catheterization during pregnancy The patients, average age 29, underwent echocardiography at an average of 27.4 weeks' gestation and catheterization at an average of 31.7 weeks. Such evaluations are used to diagnose, manage, and determine the severity of pulmonary hypertension during pregnancy, especially in women ...
