Aortic Valve Stenosis

Recent evidence suggests that transcatheter aortic valve replacement (TAVR) is feasible for treating severe aortic valve stenosis (AS) in patients who are considered high risk for elective surgery. However, it is still unclear whether TAVR is a better option than surgical aortic valve replacement for severe AS[…] [ncbi.nlm.nih.gov]

Dissecting Aortic Aneurysm

Herz. 1987 Jun;12(3):187-93. Abstract Real-time color flow mapping by two-dimensional Doppler has now come into widespread use. However, its application via conventional transcutaneous approaches to dissecting aortic aneurysm has some limitations where visualization of the descending aorta is concerned. Its[…] [ncbi.nlm.nih.gov]

Traumatic Aortic Rupture

Abstract This study was undertaken to determine whether direct measurement of mediastinal width or computation of ratios of measurements of easily detectable mediastinal structures is more effective than the subjective impression of "mediastinal widening" in selecting trauma patients for aortography. A group of[…] [ncbi.nlm.nih.gov]
