Echocardiographic Assessment of Aortic Valve Stenosis: A …
Echocardiography is the key tool for the diagnosis and evaluation of aortic stenosis. Because clinical decision making is based on the echocardiographic assessment of its severity, it is essential that standards are adopted to maintain accuracy and consistency across echocardiographic laboratories.
Aortic stenosis - Echocardiography, diagnosis, grading, causes, …
Echocardiographic assessment of the severity of aortic valve stenosis relies on peak velocity, mean pressure gradient and aortic valve area (AVA), which should ideally be concordant. In 25% of patients these parameters are discordant (usually aortic valve area <1 cm² and mean pressure gradient <40 mmHg).
Echocardiography is the key tool for the diagnosis and evaluation of aortic stenosis. Because clinical decision-making is based on the echocardiographic assessment of its severity, it is essential that standards are adopted to maintain accuracy and consistency across echocardiographic laboratories.
