“…The planimetered AVA indicates the maximal opening area in the systolic phase, whereas the CE-based AVA indicates the average systolic opening of the aortic valve because the VTI is a time-averaged systolic velocity [8]. If the ascending aorta is narrow, pressure recovery phenomenon distal to the stenosis can lead to a measurement error in the CE-based AVA [15,16].…”

Owing to modern epidemiology in Western countries, ageing represents a growing health burden. In general, because of age itself and comorbid conditions, all clinical cardiovascular manifestations have a higher mortality rate and a worse outcome in older people compared with in younger individuals. Diagnosis of the disease in the elderly in an emergency setting is particularly challenging for the practitioner. Age-related cardiovascular changes and comorbid conditions may alter signs, symptoms and adaptation to the disease and response to treatment. Bedside Doppler echocardiography is likely to play a major role in guiding diagnosis, therapeutic strategies and prognosis. The purpose of this review is to appraise the application of echocardiographic examination in helping the clinician facing emergency situations that involve the cardiovascular system in the older population.
