A patient with chronic pulmonary embolism is reported in whom severe dyspnea, massive hemoptysis and pleuritic pain appeared to be precipitated by pulmonary scan. Neither the hemoptysis nor pleurisy had been present previously. It is believed that the procedure aggravated her cor pulmonale, with the development of hemorrhagic changes in previous areas of infarction. Pulmonary scanning is a valuable and generally innocuous procedure in the diagnosis of suspected pulmonary embolism. Serious complications may result, however, from the acute alteration in pulmonary hemodynamics and diffusion induced by such superimposed macroaggregate embolism, especially when the underlying pathology has damaged the pulmonary vascular bed extensively. Under these circumstances, certain recommended precautions should be taken.

    Platypnea-orthodeoxia is a rare syndrome characterized by dyspnea and deoxygenation induced by a change to a sitting or standing from a recumbent position. It is the result of posturally accentuated intracardiac or pulmonary right-to-left shunt leading to arterial oxygen desaturation. Only few...

    Background: Adenosine is widely used for stress-testing in myocardial perfusion imaging. During adenosine infusion, dyspnea is one of the main complaints of patients. The aim of this study was to determine whether dyspnea during adenosine infusion is caused by bronchospasm. Methods: Fifty-four...
