Name of the Procedure:

• Common Name: Coronary Artery Revascularization
• Medical Term: Percutaneous Transluminal Revascularization of Chronic Total Occlusion, Coronary Artery Branch or Coronary Artery Bypass Graft (HCPCS C9607)

Summary

This procedure involves opening a chronically blocked coronary artery using a combination of drug-eluting stents, atherectomy (plaque removal), and angioplasty (using a balloon to widen the artery). It aims to restore blood flow to the heart muscle, executed through minimally invasive techniques.

Purpose

Medical Conditions:

• Chronic total occlusion (CTO) of a coronary artery
• Severe coronary artery disease (CAD) not responsive to medication or other treatments

Goals:

• Improve blood flow to the heart muscle
• Alleviate symptoms such as chest pain (angina) and shortness of breath
• Enhance overall heart function
• Reduce the risk of heart attack

Indications

Symptoms and Conditions:

• Persistent chest pain (angina) despite medication
• Diagnosis of a chronic total occlusion in one of the coronary arteries
• Proven ischemia (reduced blood flow) through diagnostic tests like stress tests or imaging

Patient Criteria:

• Patients with significant symptoms impacting their quality of life
• Inadequate response to other less invasive treatments

Preparation

• Fasting for at least 6-8 hours before the procedure
• Adjustments to medications, especially blood thinners and diabetes medications
• Complete diagnostic assessments like ECG, blood tests, and imaging (CT angiography or MRI)
• Clear instructions from the healthcare team regarding pre-procedure routine

Procedure Description

1. Anesthesia: Administered to ensure patient comfort (local anesthesia along with sedatives, or general anesthesia in some cases).
2. Access Point: A catheter is inserted into a vessel (usually via the groin or wrist) and guided to the site of the blockage.
3. Imaging: Real-time X-rays (fluoroscopy) are used to guide the catheter.
4. Atherectomy: Specialized tools are used to remove plaque buildup from the arterial wall.
5. Angioplasty: A small balloon is inflated at the site of the blockage to widen the artery.
6. Stenting: Placement of a drug-eluting stent to keep the artery open and promote healing.
7. Final Imaging: Confirming the patency (open status) and adequate blood flow through the treated artery.

Tools and Technology:

• Catheters, guidewires, balloon catheters, drug-eluting stents, atherectomy devices
• Imaging technology (fluoroscopy)

Duration

• Typically lasts between 1-3 hours, depending on complexity

Setting

• Performed in a hospital's catheterization lab (cath lab)

Personnel

• Interventional cardiologist
• Nursing staff specialized in cardiology
• Radiologic technologist
• Anesthesiologist (if required)

Risks and Complications

Common Risks:

• Bleeding or bruising at the access site
• Allergic reaction to contrast dyes used in imaging

Rare Risks:

• Damage to the artery or adjacent vessels
• Heart attack, stroke
• Infection
• Renal impairment from contrast dye

Management:

• Immediate medical attention and intervention for any complications

Benefits

• Relief from symptoms like chest pain and shortness of breath
• Improved quality of life and exercise tolerance
• Reduced risk of heart attacks and related complications
• Benefits usually realized within days to weeks

Recovery

• Short hospital stay (typically 1-2 days)
• Instructions on wound care at the catheter entry site
• Gradual return to normal activities, usually within a week
• Follow-up appointments to monitor progress
• Continuing medication regimen as advised by healthcare provider

Alternatives

Treatment Options:

• Medical management with medications
• Coronary artery bypass grafting (CABG)
• Lifestyle modifications and cardiac rehabilitation

Pros and Cons:

• Medications and lifestyle changes are less invasive but may not be sufficient for severe cases.
• CABG might be preferred for complex or multiple blockages, but it is more invasive with a longer recovery time.

Patient Experience

During the Procedure:

• Minimal discomfort due to anesthesia and sedation
• Sensation of pressure or mild discomfort at the access site

After the Procedure:

• Mild pain or soreness at the entry site
• Possible feeling of tiredness or drowsiness from the sedation
• Pain management through prescribed medications
• Comfort measures like keeping the access site clean and avoiding strenuous activities for a few days
