In cases of stenosis and insufficiency that occur in the aortic valve, repair or replacement of the valve (aortic valve replacement) is performed in our clinic with an open operation in accordance with the indications of the operation. In addition, TAVI procedure applied to the patient with aortic stenosis without open surgery with the catheter method of inguinality which is a developing method in recent years has been successfully applied by our experienced team trained abroad in our clinic. The TAVI method is recommended for patients who are at high risk to remove open surgery for aortic valve closure. Otherwise, this method can be applied to patients with any disability for open surgery. Patients with advanced elderly, lung, liver, or renal dysfunction in this regard are considered to be at high risk for open surgery before they have undergone other open heart surgery.
