The role of transesophageal echocardiography in the management of patients with acute and chronic pulmonary thromboembolism.
Acute and chronic pulmonary thromboembolism carry high mortality. The role of transesophageal echocardiography (TEE), however, has not been well delineated in patients with suspected pulmonary thromboembolism. The aim of the present study was to demonstrate the value of Tee in patients with various clinical manifestations of pulmonary thromboembolic disease. Twelve patients--ten males and two females, age 47-85 years--are presented in whom central pulmonary thromboembolism was found by TEE. Six patients were referred for breathlessness and had moderate to severe pulmonary hypertension (PH) with (3) or without (1) right atrial thrombus or had right heart dilatation (1) or right ventricular myxoma (1) on transthoracic echocardiography (TTE). Thrombolysis (2), surgery (2), and heparin (2) treatment was performed without angiography. All but one patient recovered. Six patients had severe PH by TTE, one of them had a right atrial thrombus. Angiography was done in five patients in whom surgery was considered. Pulmonary thromboendarterectomy was successfully performed in two patients, it was contraindicated in two patients for advanced age or severe left ventricular dysfunction, both patients died during follow-up, and two patients were waiting for surgery.


CONCLUSIONS
TEE has a definite role in the management of patients with acute pulmonary thromboembolism or in pulmonary embolism associated with right-sided intracardiac masses and in the selection of patients with PH for pulmonary thromboendarterectomy.
