    Color flow imaging along with injection of agitated saline into a peripheral or central vein may assist in the detection of residual intracardiac shunts or acquired baffle leaks. [journals.lww.com]

Two-dimensional (2D) echocardiography with color Doppler imaging is the current modality of choice to establish the diagnosis of SAS (see Workup). [emedicine.medscape.com]

Right-to-left commissures have worse prognosis in bicuspid aortic than anteroposterior commissures in developing aortic stenosis. Also eccentric orifices have worse prognosis than central orifices in developing aortic stenosis. [pedcard.rush.edu]

Prognosis Although natural history studies have not delineated the annual mortality rate, 2-10% of sudden deaths are reported in untreated individuals with severe left ventricular outflow tract (LVOT) obstruction, including subvalvar aortic stenosis [emedicine.medscape.com]

If postoperative pulmonary hypertension persists, the prognosis is unfavorable, with right ventricular failure occurring commonly ( 65,66 ). [journals.lww.com]

Etiology The rarity of fixed subaortic stenosis in newborns and its absence in the developing heart, its progressive and probably acquired nature have been the subject of several studies (18). [slideshare.net]

Epidemiologic studies suggest that these defects account for nearly 30% (range, 16%–50%) of all cases ( 47,48 ). Communications at the ventricular level can be found in isolation or may be seen in the context of other structural malformations. [journals.lww.com]

Pathophysiology. To maintain cardiac output, right ventricular pressure rises. In severe stenosis, right ventricular end-diastolic pressure may also increase. [elearning.sumdu.edu.ua]

Pathophysiology Obstruction at any level causes increased left ventricular systolic pressure and wall stress and consequent left ventricular hypertrophy. Left ventricular hypertrophy produces subendocardial ischemia and diastolic dysfunction. [mhmedical.com]
