What is TAVI Prosthetic Valve Dysfunction?

Transcatheter aortic valve implantation (TAVI/TAVR) has become the standard of care for aortic stenosis patients at high surgical risk. Over time, the prosthesis may develop structural valve deterioration, leaflet thickening, thrombosis, paravalvular leak or endocarditis.

Structural valve deterioration typically develops over 5–10 years and presents as restenosis or regurgitation. Other mechanisms include subclinical leaflet thrombosis (HALT), infective endocarditis and stent frame fracture.

Treatment options include anticoagulation, redo surgical valve replacement and — most commonly — valve-in-valve TAVI (a second transcatheter valve implanted inside the existing prosthesis).

Symptoms

Recurrent dyspnea
Reduced exercise capacity
Syncope or presyncope
Anginal chest pain
New heart failure signs
Palpitations
Fever suggesting endocarditis

Risk Factors

Advanced age
Long-standing TAVI prosthesis
Small prosthesis size
Prosthesis thrombosis
Hemodialysis
Diabetes and chronic kidney disease
Previous endocarditis

When to See a Doctor?

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

  • New dyspnea after TAVI
  • Anginal chest pain
  • New murmur
  • Unexplained fever
  • Exercise intolerance
  • Edema or syncope

Treatment Methods

01
Evaluation with TTE and TEE
02
Cardiac CT for stent frame and leaflet analysis
03
Anticoagulation for HALT
04
Valve-in-valve TAVI
05
Surgical valve replacement in selected cases
06
Endocarditis treatment
07
Heart team assessment

Hypertension (High Blood Pressure)

Kardiyoloji

Hypertension is a condition in which blood pressure readings remain above 140/90 mmHg; early treatment helps prevent serious complications.

Coronary Artery Disease

Kardiyoloji

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

Kardiyoloji

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).
