Review Comparative StudyCoronary CT angiography versus standard of care for assessment of chest pain in the emergency department.
Use of coronary CT angiography (CTA) in the early evaluation of low-intermediate risk chest pain in the emergency department represents a common, appropriate application of CTA in the community. Three large randomized trials (CT-STAT, ACRIN-PA, and ROMICAT II) have compared a coronary CTA strategy with current standard of care evaluations in >3000 patients. ⋯ Together, these trials provide definitive evidence for the use of coronary CTA in the emergency department in patients with a low-to-intermediate pretest probability of coronary artery disease. Clinical practice guidelines that recommend the use of coronary CTA in the emergency department are warranted.

Case ReportsStanford type A aortic dissection with pulmonary arterial intramural hematoma and pulmonary hemorrhage.
A rare complication of a Stanford type A aortic dissection is extension along the pulmonary arteries. We present a case that shows main and right pulmonary artery intramural hematoma and pulmonary hemorrhage in an 80-year-old woman who presented with a type A Stanford aortic dissection. The 11-month follow-up multidetector CT angiogram for this patient showed that the right pulmonary artery had become aneurysmal.
