In cases of asymptomatic aortic stenosis where the transvalvular velocity is 4 m/s or higher, the recommended frequency for echocardiographic monitoring is every 0.5 to 1 year. This recommendation is based on the understanding that a transvalvular velocity of 4 m/s indicates moderate to severe aortic stenosis and carries a higher risk of progression. The annual or semi-annual echocardiograms allow for close monitoring of the condition, enabling timely intervention when symptoms arise or if there are significant changes in the echocardiographic findings.

Regular echocardiography is crucial in managing patients with aortic stenosis because the disease can progress rapidly, and asymptomatic patients can have a sudden onset of symptoms due to hemodynamic changes. Following these guidelines helps ensure that any deterioration in the patient's condition can be noted and addressed proactively.
