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.

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.

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).

Ensure that the management of patients with aortic valve disease is based around contemporary data and optimal echocardiographic assessment. In some situations, this BSE guidance differs from the most recent European or American guidelines (4, 5, 6).

Echocardiography represents the most important diagnostic tool in the evaluation of aortic stenosis. The echocardiographic assessment of its severity should always be performed through a standardized and stepwise approach in order to achieve a comprehensive evaluation.

Valve stenosis is a common heart disorder and an important cause of cardiovascular morbidity and mortality. Echocardio-graphy has become the key tool for the diagnosis and evalu-ation of valve disease, and is the primary non-invasive imaging method for valve stenosis assessment.

2013年12月29日 · In a DI ≤25, there is almost always a severe aortic valve stenosis . Low-gradient aortic stenosis vs . Pseudo stenosis. In an aortic valve stenosis with a low gradient (< 30 mmHg), and poor left ventricular function is to be a valve surface calculated .

2018年1月10日 · Echocardiographic assessment of the severity of aortic valve stenosis (AS) usually relies on peak velocity, mean pressure gradient (MPG) and aortic valve area (AVA), which should ideally be concordant. In 20%-30% of patients, these parameters are discordant (usually AVA <1 cm² and MPG <40 mmHg).
