For purposes of this survey, readers were asked to assume that they were consulted on a hospitalized middle aged patient who has been diagnosed with stage IV non-small cell lung cancer. The patient has shortness of breath in the absence of an important pleural effusion. There is no endobronchial obstruction and there is no evidence for pulmonary embolism. A CT scan demonstrates a pericardial effusion. Although echocardiography demonstrates a large pericardial effusion with no evidence for tamponade, there is some mild diastolic collapse.

Almost all respondents manage pericardial effusions, and 90% of respondents believed that definitive management of this patient's effusion was appropriate. There were some individual/institutional differences in how definitive management was performed, but over 80% favored either pericardiocentesis or subxiphoid pericardiectomy. Surgical management favored a subxiphoid approach twice as often as a thoracoscopic approach. Few surgeons utilize either pericardioscopy or sclerosis. Most respondents favor tailoring the treatment approach to the degree of symptoms.
