Results: One of the advantages of using laser therapy in cardiovascular diseases is its non-invasiveness. It also reduces the treatment process pain and prevents massive surgical incisions and bleeding throughout the operation. Laser therapy can ensure an alternative method to treat the ischemic region of the heart and creating anastomosis of vessels.

Methods: This paper attempted to represent recent advances in laser therapy in cardiovascular tissue repairs. Three standard techniques have been explicitly described here in cardiovascular tissue repairs by laser.

Furthermore, suitable laser wavelength assortment has to interpret the complexity of the marking assembly in the tissue, as extended wavelengths tend to have more considerable diffusion depth. 6 This article aimed to represent recent advances in laser therapy for cardiovascular tissue repairs. The use of lasers in endoscopic cardiovascular surgeries, repairing heart valves, clogging valve leaks, repairing muscle tissue, and laser sutures during non-invasive operations are particularly noteworthy.

A laser beam can be captivated, reproduced, dispersed, or spread upon a tissue interface. A mixture of these events naturally arises a few times, of which the remaining result marks the laser influence that differs according to the laser specifications. Consistent with the Grotthus-Draper principle, laser energy must be immersed in causing any biotic effect on the tissue. Immersion is the alteration of beaming light force to a changed force form, typically into heat. It is only the beam that is engrossed to yield the anticipated effect on the tissue. The laser beam interface with the tissue has a common role in the laser wavelength, and it parallels the explicit immersion range of the focused chromosphere. 5

Laser is an abbreviation for &#;Light Amplification by Stimulated Emission of Radiation.&#; It has characteristics of monochromaticity, consistency, directivity, short discrepancy, and intensity. 1 With starting to use lasers in medicine and laser analysis findings, a valuable claim of spiral therapeutic and diminish ache was recognized. Still, this skill persisted in provoking satisfaction as a result of bleak considerate machinery and quantity reaction. 2 , 3 Function and efficiency comprehension, unlike trials, were accomplished to control the laser ray effects at the cellular and tissue levels. The laser beam differs from the usual light due to its wavelength, hence called monochromatic. When passed through a prism, laser ray does not split into several colors, unlike conventional beam. Therefore, noting the laser item is vital, with extreme concentration at an assumed wavelength due to which supreme radioactivity is produced, and concentration sprays to zero at other wavelengths other than the extreme. 4

Laser therapy may redevelop tissues, motivates organic role, reduces infection, and lightens discomfort. It&#;s worth and care are increasingly well known in the management of the cardiovascular diseases of numerous varieties.

Globally, cardiovascular diseases are a significant reason for death. Comprising this with all damages of the cardiovascular systems is roughly distinct. The conventional medical model frequently pursues to treat cardiovascular diseases with medications or surgically bypass or reconstruct obstructed vessels by angioplasty. These procedures were demonstrated to be highly worthwhile that protected numerous survivals. However, medication therapy may be expensive and enduring, which brings the risk of side effects with little or nothing for essential well-being and recovery. Similarly, angioplasty or surgical tasks are invasive techniques that involve side effects and threats.

Methods

In this section, we will discuss the methods of performing three main techniques in the treatment of cardiovascular diseases, namely transmyocardial laser revascularization (TMLR), laser vascular anastomosis, and laser angioplasty, and according to the experiences that exist in the field of these measures, we will review their summary.

Transmyocardial Laser Revascularization for End-Stage Ischemic Heart Diseases

In the TMLR procedure, tiny punctures are created in the patient&#;s heart muscles from inside the cavities with lasers to improve the blood flow oxygenation of the tissues from inside the heart instead of obstructed vessels ( ).

Myocardial Punctures (Red Holes) by Laser in the Ischemic Area.

The TMLR is empirically and clinically done by carbon dioxide laser. The principle behind this method is to source the extra arterial blood from the left ventricular cavity into the ischemic region of the myocardium. An insignificant tissue response was meticulously accepted in the recently generated laser conduits. It is shown that the created ducts with a diameter of about 0.2 mm remain open for a long time and perform tissue oxygenation. These results revealed the achievability of durable patency of laser conduits and their possible medical use. 7

Revasculation by coronary artery bypass grafting (CABG) or angioplasty is required, and nothing else is sufficient for patients suffering from ischemic heart disease. Still, where it could not be practical or technically feasible for any reason, myocardial revascularization by laser or TMLR might be suggested.8

Mirhoseini et al made laser canals, using carbon dioxide, in the kinetic and dyskinetic parts of the left ventricular myocardium and instantaneously implemented CABG in all patients and reported acceptable and good results.9,10 In their series, they choose cases with end-stage coronary artery illness, for whom percutaneous coronary intervention and CABG cannot be performed due to diffuse stenosis and small-caliber coronary arteries.11

Various exceptional advantages exist in TMLR:

1. No necessity of extracorporeal circulation.

2. Stress-free work-on and short operating time.

3. Lower costs.

4. Quick body refurbishment.

5. 12

   Effectually affordable.

Subsequent studies on this method have shown that TMLR is more effective in relieving the symptoms of angina pectoris in patients and may not have a favorable effect on other cardiac indices. It has been ruled out that angina is only caused by infarction on the foundation of echocardiography and radionuclide data. The more significant incidence of myocardial infarction (15.0% vs. 8.9%), heart failure (27% vs. 11%), and raised serum creatinine kinase (> IU/L in 50% of patients) after TMLR showed imperative myocardial damage, which has durable complications.13,14

The information gathered from the function of the heart muscles after TMLR is also a little distressing. Echocardiography exhibited that 27% of patients who underwent TMLR had a significant reduction in the left ventricular function related with 11% of the medically cured group (P < 0.). Therefore, echocardiographic observations after TMLR can be a valuable strategy for correct therapeutic results. 15

Laser Vascular Anastomosis

Laser vascular anastomosis has long been considered. Extensive studies have been conducted in this field, and finally, the appropriate technique is performed in research cases. The association between the output and the X-ray time of a carbon dioxide laser was considered along with the laser-tissue response in the initial testing. Inflammation, disturbance, and evaporation of the flexible strands of the aorta could be created in percentage to the laser output if the laser productivity of 100 milliwatt (mW) was nonstop illuminated on the matching point for >10 seconds. The peak laser yield was 20&#;40 MW and 6&#;12 s/mm for vascular anastomosis of lesser-caliber vessels in the margins.16--18Side-to-side, end-to-side, and end-to-end anastomosis at the position of the femoral arteries and veins or the carotid arteries and veins was accomplished by a truncated energy carbon dioxide laser ( ).

(A-D): A Cross-connection Between the Adjacent Channels by Laser Sutures.

The best diameter for vessels to be anastomosed by laser is from 2 to 10 mm. The notched ends of the vessels are attached with Stop-over sutures of 5-0 monofilament suture material to firmly held the vessel edges in place. Sometimes the posterior wall of the femoral artery and its vein was sutured in the conformist procedure by 5-0 suture supplies, and spots of anastomosed by laser were minutely inspected as a controller. The anterior wall was anastomosed by squat energy carbon dioxide (20&#;40 mW) for 6&#;12 s/mm. 19 The concentrated laser ray was utilized and progressed very gradually to the anastomosed line. The distance between break sutures was preserved at no further than 5 mm. 20

Two key facts were considered in finalizing vascular anastomosis. One is situated near the border of the vessels fitted with certain satisfactory stop-over sutures. The distance between break stitches requires to be fewer than 5 mm. An additional one was to emphasize the light ray on the anastomosed route. At this moment, the light ray must be stimulated repetitively, little by little. The Laser beam has to be persistent until the color of the lengthwise anastomosed mark modifies to lead-black or black-brown.21

Laser Angioplasty for Cardiovascular Disease

The practicality of laser angioplasty might be established in the surgical tasks. In surgery, different kinds of lasers are extensively used in the academic world.22-28 An argon laser is used to evaporate the atherosclerotic signs.

Through laser angioplasty, the usage of an angiography scope is unavoidable to detect arterial calcifications. Laser shots are nonstop to remove atherosclerotic plaques under angioscopic supervision until an extensive opening of the vessel thrombus is noticed( ).

Laser Angioplasty to Eliminate Atherosclerotic Plaques.

In laser angioplasty, angiography scope and intravascular ultrasound steerage remain necessary to calculate the physical appearances of the athermanous signs and the arterial wall earlier and once during the laser therapy. Integrating computed tomography and echocardiography images30 during this procedure is very useful in guiding the laser into the right site. Infrequently, the endoscopic ally may illustrate that immediate and far end parts stayed collected of constricted athermanous signs, or the intermediate slice was not obstructed or occupied with renewed tumor. Based on medical experiences, laser angioplasty should be counseled to exclude or decrease the constricted or congested variations of tiny sections among 10 cm in the extent of a marginal pathway and needs a supplementary balloon angioplasty.31

Arteries are thick-walled blood vessels. They carry oxygen-rich blood away from the heart to surrounding organs and cells. When properly functioning, they allow the smooth passage of blood. They are part of the circulatory system and play a vital role in having a healthy heart.

It is important to avoid factors that cause damage to the arterial walls, as this can lead to inadequate blood supply distribution. Clogged arteries can place you at risk for a stroke or myocardial infarction.

Atherosclerosis

Cholesterol and calcium accumulate along the vessel walls, creating plaque in the arteries. The walls narrow from the build-up causing partial to complete blockage. This is called atherosclerosis, often referred to as hardening of the arteries.

In some cases, atherosclerosis is genetically passed down. It is also a naturally occurring consequence of aging. Diet and lifestyle have shown to start and worsen its progression.

Causes of plaque buildup include:

&#; Elevated blood pressure

&#; Elevated cholesterol

&#; Elevated blood sugar

&#; Tobacco use

&#; Alcohol use

&#; Obesity.

&#; Unhealthy eating

&#; Lack of exercise

Peripheral Arterial Disease (PAD)

Peripheral arterial disease is caused by atherosclerosis. Peripheral arteries feed the legs, stomach, arms, and head with nutrient-filled blood. PAD can occur in any blood vessel but it is most common in the lower extremities.

The prevalence of PAD increases with age and can affect both men and women. Its severity can range from asymptomatic to symptomatic. Symptoms of PAD include:

&#; Leg weakness or numbness

&#; Leg pain while walking

&#; Pain or cramping in the buttocks, hips, thighs, feet (less common), or calf muscles (most common)

&#; Hair loss on your legs

&#; Discomfort and in your legs and feet even while resting

&#; Cold legs or feet

&#; Long-lasting sores on your toes, legs, or feet

&#; Poor nail and hair growth

&#; Discoloration of your legs

&#; A weakened dorsalis pedis pulse (on the top of the foot)

&#; Claudication or impaired walking

Note that blockages may still be present with no pain at all.

The care team for the treatment of PAD usually includes your primary doctor, a cardiologist, and a vascular specialist.

Treatment of Peripheral Arterial Disease

Laser atherectomy is recommended for patients who are unable to undergo angioplasty or stenting. It is also recommended for patients with severe narrowing of the peripheral arteries. Some physicians suggest laser atherectomy for diabetic patients.

What Is Laser Atherectomy?

Atherectomy is a minimally invasive, endovascular surgical procedure. It is used in the removal of plaque from inside the arterial vessels.

In peripheral laser atherectomy, a catheter is inserted into the artery and guided to the damaged areas. Laser energy is pulsed, vaporizing the plaque and breaking it down to carbon dioxide and water.

The procedure is done under local anesthesia and takes one to three hours. The patient must lie flat for three to six hours after surgery. Normal activities may begin again 24 to 48 hours after the procedure. Your doctor will provide specific directions for your recovery.

Are You a Candidate for Laser Atherectomy?

Each case differs. An individual evaluation will determine the best course for your situation.
