A Rare Case of Severe Aortic Regurgitation with Silent Ascending Aortic Dissection

Classically, ascending aortic dissection (AD) presents as sudden, severe chest pain that is tearing type and radiates to the back. Herein, we present a rare case of severe aortic regurgitation with silent ascending AD, which had no chest pain symptoms. The aortic valve apparatus probably masked this AD; therefore, it was not detected by echocardiography and during the surgery.

Aortic Arch Obstruction

To evaluate the predictive accuracy of two-dimensional echocardiography in the diagnosis of aortic arch ebstruction, 540 consecutive patients aged 2 days to 15 years (mean 2 months) who underwent subsequent cardiac catheterization and angiography were prospectively studied. At angiography, 51 patients had aortic arch obstruction; of these, 35 had juxtaductal coarctation, 15 isthmic hypoplasia a...

Lower Urinary Tract Obstruction

Lower urinary tract obstruction is defined as partial or complete obstruction of the urinary tract at the level of the urethra and the bladder. The posterior urethral valves are the most common cause, 9 percent of the fetal uropathies. The incidence range is wide, because of different databases show different populations. The most severe obstructive uropathy is in patients with kidney damage, o...

Aortic obstruction: anatomy and echocardiography

Echocardiography is a valuable non-invasive technique for identifying the site and type of aortic obstruction. Knowledge of the morphological details of each type of obstruction is the basis for correct interpretation of the diagnostic images and clinical decisions. This study was undertaken to correlate the echocardiographic images with anatomic specimens of equivalent valvular and supravalvul...
