What is Heart Valve Prosthesis Follow-up?

Heart valve prosthesis follow-up is the long-term surveillance of patients implanted with a mechanical or bioprosthetic valve. Mechanical valves require lifelong anticoagulation (warfarin), while bioprosthetic valves generally do not after 3–6 months, but they carry a risk of structural degeneration.

Thromboembolic events and anticoagulation-related bleeding are the main complications in mechanical valves. The INR target depends on valve type and position (usually 2.5–3.5). Bioprosthetic valves may degenerate structurally over time.

The risk of infective endocarditis persists for life with both types. Paravalvular leak, prosthetic valve thrombosis and pannus formation are complications that require monitoring.

Annual echocardiography, INR monitoring (in mechanical valves), endocarditis prophylaxis and patient education are core components of long-term follow-up.

Symptoms

Features of prosthetic valve dysfunction include:
New or worsening dyspnea
Palpitations and irregular heartbeat
Fever (suspected endocarditis)
New or changed murmur
Neurologic symptoms from embolic events

Risk Factors

Poor anticoagulation control in mechanical valves
Dental and invasive procedures (endocarditis risk)
Advanced age and renal failure (accelerated bioprosthesis degeneration)
Pregnancy (difficult anticoagulation in mechanical valves)
Non-adherence to medication and follow-up

When to See a Doctor?

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

  • New dyspnea or exercise intolerance
  • Fever (>38°C) and malaise (endocarditis?)
  • Bleeding on anticoagulant therapy

Treatment Methods

01
Lifelong warfarin in mechanical valves (per INR target)
02
Regular INR monitoring (point-of-care or laboratory)
03
Annual echocardiographic assessment of prosthesis function
04
Endocarditis prophylaxis for dental procedures
05
Reoperation or TAVI-in-TAVI for bioprosthesis degeneration
06
Patient education (medication adherence, diet, warning signs)

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

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