Understanding Laser Angioplasty: A Breakthrough Treatment for Heart Block

Quick Summary

  • Laser angioplasty is a minimally invasive procedure that uses a laser to open blocked arteries.
  • The procedure is performed under local anesthesia and typically takes less than an hour.
  • Laser angioplasty is a safe and effective treatment for blocked arteries and has a success rate of between 85% and 93%.

Laser angioplasty, introduced in the early 1980s, is an innovative technique for managing cardiovascular diseases, such as obstructions and internal damage. It is a laser-assisted procedure to open heart blockages and is used as an adjunctive therapy with traditional percutaneous coronary intervention (PCI). 

Murthy (2013) stated that the procedural success rate of laser angioplasty is between 85% and 93%. For those with a blocked heart artery and who do not want to undergo invasive surgery, laser treatment for heart block is the option. Read on for a detailed overview of the procedure, its benefits and potential risks.

What is Laser Angioplasty?

Laser angioplasty is a minimally invasive medical procedure to treat blockages or narrowed blood vessels. This innovative procedure uses the precision of laser technology to vaporise fat and cholesterol deposits (plaque) and other substances (calcium and cellular wastes) blocking the heart arteries. It removes the blockages from the blood vessels, enabling appropriate blood circulation.

The procedure-associated risks of percutaneous coronary intervention (PCI) encouraged the development of an alternative laser treatment approach for heart block to address the shortcomings. Unlike PCI, where the substances causing the plaque are compressed, laser treatment for heart block vaporises the obstruction. It helps manage untreatable locations and minimises the rate of complications or restenosis (contraction in the diameter of the blood vessel post-PCI).

Who Needs Laser Angioplasty?

Laser treatment for heart block is suitable for people with health conditions that cause narrowing of the coronary arteries while decreasing the blood flow. These include the following:

  1. Coronary Artery Disease (CAD): Laser heart surgery is often considered for individuals with CAD. It is performed when traditional angioplasty or stent placement is not feasible due to heavily blocked arteries.
  2. Severe Arterial Blockages: It may be suitable for individuals with severe atherosclerotic blockages causing angina (chest pain) or increasing the risk of heart attack. It helps restore the blood circulation, relieving the symptoms.
  3. Coronary Artery Calcification: Calcified deposits may require laser angioplasty for effective plaque removal. The procedure helps remove calcium and plaque deposition from the coronary artery.
  4. Concomitant Arterial and Electrical Issues: It is beneficial in cases where both arterial blockages and heart block coexist.

Benefits of Laser Angioplasty

Laser treatment for blocked heart arteries offers the following benefits:

  1. Improved Blood Flow: Laser treatment for heart block restores proper blood flow, alleviating symptoms like chest pain and risk of heart attack.
  2. Precision: Laser treatment for heart block uses high-power ultraviolet pulses. These precisely target and evaporate the plaque, reducing the risk of damage to arterial walls.
  3. Efficacy: It is effective for heavily calcified lesions where traditional angioplasty may be less effective.
  4. Minimally Invasive: It is a laparoscopic procedure requiring minimal to no incision. Reduced invasion reduces the risk of complications associated with open surgeries.
  5. Reduced Scars: Smaller incisions mean less scarring and quicker recovery, unlike open-heart surgery
  6. Shorter Hospital Stays: It facilitates shorter hospital stays and a faster return to daily activities.
  7. Customisation: The laser treatment procedure for heart block can be tailored to your unique blockage removal needs, offering personalised and dedicated treatment options.

How is Laser Angioplasty for a Blocked Heart Artery Performed?

Laser treatment for blocked heart arteries is typically done in the following steps(2):

  1. Catheter Insertion: A flexible tube is inserted into the blood vessels through the chosen entry point. It is then carefully threaded through the vascular system until it reaches the blocked coronary artery.
  2. Guidewire Placement: An even thinner wire is passed through the catheter and into the blocked artery. It helps guide the catheter to the accurate location of the blockage.
  3. Laser Fibre Insertion: Once the catheter is correctly positioned, a laser fibre is passed over the guidewire. It emits high-intensity, focused light energy.
  4. Laser Ablation: The laser is activated, and its energy is directed at the plaque buildup within the artery. It dissolves the plaque, breaking it down into smaller particles. This process opens up the artery, restoring blood flow.
  5. Monitoring: The medical team monitors the progress using fluoroscopy or intravascular ultrasound (IVUS) throughout the procedure. This is done to ensure the blockage is accurately treated.
  6. Completion and Recovery: Once the procedure is successful, the blockage is cleared, and the catheter is carefully removed. Pressure may be applied at the insertion site to prevent bleeding. The patient is then observed for a few hours in a recovery area.

What to Expect After Laser Angioplasty Treatment?

After the surgery, the medical team will closely monitor your vital signs in a recovery area and then shift you to your designated bed.

The recovery time could range from a few days to a few weeks. It depends on your overall health and the complexity of the procedure.

In-Hospital Recovery

  1. Wound Care:  The medical team will care for the wound at the incision point to keep it clean and dry. 
  2. Medications: Your doctor may prescribe painkillers and blood thinners to help manage post-operative pain and prevent complications.
  3. Hospital Stay: It varies from one person to the other. While some may get discharged on the same day, others might stay at the Hospital overnight, depending on their specific condition and procedure complexity.

At-Home Recovery 

  1. Diet: Patients must drink 6-8 glasses of water. It maintains hydration and helps detox your body. Maintain a healthy, balanced diet rich in fibre and nutrients. Avoid food containing saturated fat to prevent cholesterol buildup in your arteries.
  2. Physical Activity: Avoid lifting heavy objects and strenuous physical activities for at least 24 hours post-discharge. It may strain the wound. Exercise regularly as advised by your doctor.
  3. Lifestyle Changes: Avoid smoking and drinking alcohol. If you have high blood pressure and diabetes, monitor them regularly to detect and treat potential complications.

Risk and Complications of Laser Angioplasty

Although laser angioplasty is a safe and effective treatment option, it might have some risks and potential complications:

  1. Bleeding: The catheter insertion site can lead to bleeding or hematoma formation (a bruise that causes blood to accumulate under the skin).
  2. Allergic Reactions: Some patients may suffer allergic reactions to the contrast dye used in the procedure.
  3. Arterial Spasm: Coronary spasms (abrupt contraction of the arteries) may occur during the recovery period after laser treatment for heart block. 
  4. Dissection: The procedure can cause arterial dissection (separating the arterial layers).
  5. Infection: Although minimal, there is a risk of infection at the catheter insertion site.
  6. Restenosis: Rarely after getting laser treatment for heart block, recurrent narrowing of the treated artery (restenosis) can occur.

When is Consultation with a Doctor Needed?


The first follow-up is generally scheduled one week after the surgery. Then, the doctor will likely schedule the appointment every three to six months for the first year (depending on your overall health).

During the assessment, the healthcare practitioner performs a physical examination. They may order a stress test to detect potential worsening of your cardiovascular condition. 

However, consultation with a doctor is essential if any unusual symptoms or concerns arise after laser angioplasty for blocked heart arteries. These include :

  1. Persistent or worsening chest pain with no relief by medications
  2. Unusual bleeding or signs of infection at the catheter insertion site
  3. Sudden onset of severe shortness of breath
  4. Irregular heart rhythms, especially while performing physical activities
  5. Swelling, redness, or warmth at the catheter insertion site

Risks of Delaying Laser Angioplasty

Delaying laser treatment for heart block can entail risks and complications:

  1. The procedure efficacy decreases over time as complex or worsened blockages are challenging to treat.
  2. Arterial blockages worsen, increasing the risk of heart attacks or other cardiovascular events.
  3. Symptoms like chest pain (angina) may become more prominent and intense.
  4. Increased chances of undergoing more invasive and higher-risk techniques like coronary artery bypass grafting (CABG) and pacemaker implantation.
  5. Prolonged reduced blood flow can lead to severe damage or rupture of heart muscle tissue.
