Non-surgical Treatment of Aortic Stenosis (TAVI)

The method shortly called as TAVI (Trans catheter Aortic Valve Implantation); in fact explains the procedure of setting aortic valve by using catheter method without performing open heart surgery. Biologic heart valves are used during this procedure which are used in the valve changing operations both in world and in our country. In TAVI method, this biologic valve is placed inside a stent sheath and when the stent is opened the valve is tightly hold and placed to the region. 2 different techniques can be used during this method: In the first technique, the valve is advanced with the aid of catheter from inguinal to heart like in the angiography applications and placed here bt opening the stent mechanism.

Other technique is applied if there is an occlusion in the arteries at inguinal or abdominal region that will be used to reach to the heart. In this technique, approximately 4-5 cm small incision is performed at chest anterior wall and reached to the end portion of the heart and valve is placed via the catheter advanced from here. In both methods, stopping heart and open operation are not required. The procedure can be performed under local anesthesia without general anesthesia. The patients are taken to coronary intensive care unit after the TAVI procedure.

A blood thinning medication is given to the patient at the moment and the patient is followed in the hospital for 4-5 days under normal patient conditions. The patient is discharged at the end of this period. The patient who has sent to home is coming back to control after a few days of rest and continue to normal life. TAVI method is primarily recommended for high risk patients who cannot handle open surgery for valve placement. Except this, this method can be applied for the patients who have a difficulty for open surgery.

For this subject, especially very old, patients with lung, liver or renal functional disorders or patients with previous open heart surgery history are accepted as high risk patients for open surgery. TAVI method is known to be effective for these patients who are not appropriate for open surgery in terms of extending life span and recovery of the patient’s clinic status.
