Chronic Total Occlusion (CTO): Causes, Symptoms & Treatment Options
Introduction
Chronic Total Occlusion (CTO) is a severe type of coronary artery disease (CAD) where a coronary artery is completely blocked for more than 3 months due to plaque buildup. This blockage prevents proper blood flow to the heart, leading to chest pain (angina), fatigue, and shortness of breath.
Despite being one of the most complex cardiac conditions, advancements in interventional cardiology, such as CTO angioplasty, have made it possible to treat these blockages successfully.
Causes of CTO
CTO is primarily caused by atherosclerosis, a condition where fatty deposits build up in the coronary arteries over time. Key risk factors include:
✔ High cholesterol levels
✔ Hypertension (high blood pressure)
✔ Diabetes
✔ Smoking
✔ Obesity
✔ Sedentary lifestyle
✔ Family history of heart disease
Symptoms of CTO
The symptoms of CTO can vary depending on the severity of the blockage. Common symptoms include:
Chest pain (angina) – especially during exertion
Shortness of breath – even with mild activity
Extreme fatigue
Heart palpitations or irregular heartbeats
Dizziness or fainting
Some patients with CTO may not experience noticeable symptoms due to collateral blood vessels that form naturally to bypass the blockage. However, these vessels are often insufficient in maintaining proper heart function.
Diagnosis of CTO
Accurate diagnosis is crucial for determining the best treatment plan. Key diagnostic tests include:
Coronary Angiography – The gold standard test to visualize artery blockages.
Electrocardiogram (ECG) – Identifies irregular heart rhythms.
Stress Test – Measures how the heart responds to exertion.
CT Coronary Angiography – A non-invasive imaging test for arterial blockages.
Treatment Options for CTO
CTO treatment aims to restore blood flow to the heart, relieve symptoms, and improve overall heart function.
1. CTO Angioplasty & Stenting
Minimally invasive procedure
Uses guidewires and catheters to open the blocked artery
A stent is placed to keep the artery open
Fast recovery & minimal hospital stay
2. Coronary Artery Bypass Grafting (CABG)
✔ Recommended for multiple blockages or severe artery disease
✔ Involves bypassing the blocked artery using a graft from another blood vessel
✔ Effective for long-term heart function improvement
3. Medication & Lifestyle Changes
Patients who are not immediate candidates for surgery or angioplasty may be managed with:
Blood thinners, cholesterol-lowering drugs, and beta-blockers
A heart-healthy diet (rich in fiber, low in saturated fats)
Regular physical activity to maintain heart health
