Valvular heart diseases cause serious health problems in Turkey as well as in Western countries. According to a study conducted in Turkey, aortic stenosis ( AS ) is second after mitral valve disease among all valvular heart diseases. AS is frequently observed in elderly patients who have several cardiovascular risk factors and comorbidities. In symptomatic severe AS , surgical aortic valve replacement ( AVR ) is a definitive treatment. However, in elderly patients with left ventricular dysfunction and comorbidities, the risk of operative morbidity and mortality increases and outweighs the gain obtained from AVR surgery. As a result, almost one‐third of the patients with serious AS are considered ineligible for surgery. Transcatheter aortic valve implantation ( TAVI ) is an effective treatment in patients with symptomatic severe AS who have high risk for conventional surgery. Since being performed for the first time in 2002, with a procedure success rate reported as 95% and a mortality rate of 5%, TAVI has become a promising method. Assessment of vascular anatomy, aortic annular diameter, and left ventricular function may be useful for the appropriate selection of patients and may reduce the risk of complications. Cardiac imaging methods including 2D and 3D echocardiography and multidetector computed tomography are critical during the evaluation of suitable patients for TAVI as well as during and after the procedure. In this review, we describe the role of echocardiography methods in clinical practice for TAVI procedure in its entirety, i.e. from patient selection to guidance during the procedure, and subsequent monitoring.
