Paper Abstract

We have previously described a fiberoptic angioscope for diagnostic use in the right heart and pulmonary arteries. The instrument has a 4 mm 0.D., a proximal flexion control lever, and a 0.8 mm inner channel used to inflate a polyurethane balloon attached to the distal end of the instrument. A conventional xenon light source provides illumination. The instrument is inserted through a right jugular venotomy and passed into the right heart and pulmonary arteries using direct vision and fluoroscopic guidance. The procedure has been performed in 4 patients with pulmonary hypertension suspected to be caused by chronic pulmonary emboli. Chronic emboli were found in two patients and central (resectable) emboli could be distinguished from peripheral ones. The third patient had normal pulmonary arterial intima and a final diagnosis of primary pulmonary hypertension was made. The fourth patient had extrinsic compression of pulmonary arteries by enlarged mediastinal nodes secondary to fibrosing mediastinitis. No complications occurred. We conclude that angioscopy appears to be useful in the diagnostic evaluation of patients with suspected chronic obstruction of the pulmonary arteries.
