What is Transcatheter Aortic Valve Implantation (TAVI/TAVR)?

Transcatheter aortic valve implantation (TAVI) delivers a bioprosthetic aortic valve via catheter without the need for open-heart surgery in patients with severe symptomatic aortic stenosis. It is usually performed through the femoral artery.

Originally reserved for high-surgical-risk and inoperable patients, current evidence shows that TAVI is safe and effective in intermediate- and low-risk patients as well. Indications continue to expand.

The procedure is typically performed under general anesthesia or sedation; hospital stay is significantly shorter than surgical valve replacement. Early mobilization and rapid recovery are key advantages.

Post-TAVI antithrombotic therapy, follow-up of conduction disturbances and regular prosthetic valve function assessment are essential parts of long-term care.

Symptoms

TAVI-eligible aortic stenosis patients typically have:
Dyspnea at rest or with exertion
Chest pain (angina)
Syncope or dizziness
Heart failure symptoms
Reduced exercise capacity

Risk Factors

Vascular complications (bleeding, dissection)
Conduction disturbances requiring permanent pacemaker (5–25%)
Paravalvular leak
Stroke risk (1–3%)
Acute kidney injury (contrast nephropathy)

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Patients with severe aortic stenosis should be evaluated for TAVI
  • New palpitations, syncope or dyspnea after TAVI
  • Leg pain, swelling or bleeding after the procedure

Treatment Methods

01
TAVI procedure (transfemoral, transapical or alternative access)
02
Dual antiplatelet or anticoagulant therapy after the procedure
03
Monitoring of conduction disturbances (ECG and telemetry)
04
Regular echocardiographic assessment of the prosthesis
05
Endocarditis prophylaxis
06
Referral to cardiac rehabilitation

Narrowing of the coronary arteries due to atherosclerosis can cause chest pain (angina) and heart attack.

Heart Failure

Kardiyoloji

Heart failure is a chronic cardiac condition characterized by shortness of breath, leg swelling, and fatigue.

Heart Attack (Myocardial Infarction)

Kardiyoloji

A heart attack is a medical emergency; because heart muscle is lost by the minute, immediate intervention saves lives.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia characterized by an irregular heartbeat and increased risk of stroke.

Heart Palpitations

Kardiyoloji

Palpitations are usually due to benign causes, but underlying cardiac rhythm disorders must be ruled out.

Heart Valve Diseases

Kardiyoloji

Valve stenosis or regurgitation increases the workload of the heart and, over time, can lead to heart failure.

Aortic Aneurysm

Kardiyoloji

Aortic aneurysms are often silent; early diagnosis allows treatment before rupture (a life-threatening tear).
