We report a case of a 39-year-old man with extensive left atrial compression by a dissecting aneurysm of the ascending aorta. Presumably this compression caused hypotension. A dissecting aneurysm of the ascending aorta, limiting left ventricular inflow by left atrial compression, has not been described in English-language medical literature before.

Methods: In 10 consecutive preoperative AAA patients (10 men; mean age 78.8 years, range 69-86), an ECG-gated CTA dataset was acquired on a 40-slice CT scanner using a standard radiation dose.
Rationale And Objectives: Automated detection and quantification of arterial calcifications can facilitate epidemiologic research and, eventually, the use of full-body calcium scoring in clinical practice. An automatic computerized method to detect calcifications in CT scans is presented.
Materials And Methods: Forty abdominal CT scans have been randomly selected from clinical practice.
