What is Chronic Total Occlusion (CTO) PCI?

Chronic total occlusion (CTO) is a 100% occluded coronary lesion of more than 3 months' duration. CTO PCI is a complex intervention that uses antegrade and retrograde approaches, dedicated guidewires, microcatheters, reentry devices and advanced imaging.

Indications for CTO PCI include refractory angina, high ischemic burden, the need to preserve or improve left ventricular function and selected multivessel disease. In experienced centers success rates reach 85–90%.

Complication rates (perforation, dissection, device loss) are higher than for standard PCI, so an experienced operator and multidisciplinary team are required.

Symptoms

Refractory exertional angina
Reduced exercise capacity
Dyspnea
Low ejection fraction
High ischemic burden
Resting angina
Chest pain and atypical symptoms

Risk Factors

Prior myocardial infarction
Long-standing coronary disease
Diabetes mellitus
Smoking
Dyslipidemia
Multivessel disease
Prior failed CTO PCI

When to See a Doctor?

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

  • Angina uncontrolled by medication
  • Detection of high ischemic burden
  • Low EF and heart failure
  • New anginal symptoms
  • Impaired quality of life due to CTO
  • Planning of multivessel PCI

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).
