What is Aortic Regurgitation Timing?

Chronic aortic regurgitation (AR) usually progresses asymptomatically; LV remodelling and dysfunction develop over time.

Surgery timing is determined by symptoms, LV ejection fraction (LVEF) and end-systolic diameter (LVESD); aortic valve replacement (AVR) or TAVI in selected patients is recommended.

Symptoms

Asymptomatic in early stages
Effort dyspnoea (DOE)
Orthopnoea, paroxysmal nocturnal dyspnoea
Wide pulse pressure (water-hammer pulse)
Diastolic murmur (Austin Flint)

Risk Factors

Bicuspid aortic valve
Aortic root dilatation (Marfan, Loeys-Dietz)
Hypertension
Infective endocarditis
Aortic dissection (acute AR)

When to See a Doctor?

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

  • Symptomatic AR (DOE, orthopnoea)
  • Severe AR + LVEF <50%
  • LVESD >50 mm or >25 mm/m2 BSA on echocardiography
  • Aortic root dilatation (>50 mm in BAV; >55 mm in tricuspid)

Treatment Methods

01
Surgical AVR (mechanical or biological prosthesis; gold standard)
02
Aortic valve repair (in selected centres; aortic root sparing)
03
TAVI (in selected high-risk surgical patients)
04
Aortic root replacement (Bentall procedure; in dilated root)
05
Annual TTE follow-up (asymptomatic moderate-severe AR)
06
Annual TTE in mild-moderate AR (LV size, function)
07
Vasodilator therapy (in symptomatic non-operative cases)
08
Beta-blocker (Marfan; aortic dilatation prophylaxis)

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).
