Ascending aortic aneurysm in a man with scleroderma.

Macrovascular involvement in scleroderma has received relatively little attention. We hereby describe a 5.6-cm ascending aortic aneurysm in a 56-year-old man presenting with increased dyspnea, diagnosed with antibody-negative, rapidly progressive diffuse cutaneous scleroderma. The patient had sclerosis and induration of all extremities, face, thorax and abdomen. Other features included Raynaud's phenomenon, arthralgia, dysphagia, dyspnea attributed to pulmonary fibrosis, pericardial effusion, and cardiomyopathy. To the best of our knowledge, there is only one other report to date in the English language of a thoracic aortic aneurysm associated with scleroderma.

Protocol for optimal detection and exclusion of a patent foramen ovale using transthoracic echocardiography with agitated saline microbubbles.

Agitated saline bubble studies in conjunction with echocardiography, in particular transesophageal echocardiography, are currently the principal means in the diagnosis of patent foramen ovale (PFO). We describe techniques and guidelines for the detection and exclusion of a PFO. The potential for misinterpretation of these bubble studies exists and therefore, several false positive and false negative scenarios are illustrated and discussed.
