A 44-year-old man was seen in the clinic because of a right atrial mass.
Six years earlier, the patient had been found to have Pneumocystis carinii pneumonia and human immunodeficiency virus (HIV) infection. He had returned to a satisfactory state of health with the use of highly active antiretroviral therapy. He did not have severe disabling symptoms from either the HIV infection or its management.
Ten months before being seen in the clinic, he had an episode of substernal pain that lasted nine hours. An exercise stress test performed at another hospital did not provoke chest pain or ST-segment depression.
