Transmyocardial Revascularization: A treatment option for Angina Patients (3d animation)
Welcome to our channel Power of Knowledge. In this video you will learn about a medical procedure called transmyocardial Revascularization.
Transmyocardial Revascularization (TMR), also known as transmyocardial laser revascularization (TMLR), is a minimally invasive surgery for severe angina, a condition related to coronary artery disease.
TMR uses special carbon dioxide (CO2) lasers to create tiny channels in the heart muscle, specifically in the left ventricle, which is responsible for pumping oxygenated blood to the body. This procedure helps improve blood flow and reduce angina symptoms.
For patients with advanced heart disease or health issues that make traditional treatments risky, TMR can be a safer and effective alternative. It is also an option for those who have previously undergone coronary artery bypass grafting (CABG) but cannot have another bypass operation.
Procedure Overview:
You'll lie on your back on an operating table, and the doctor will give you anesthesia to make you sleep.
Once the anesthesia starts working, the doctor will make a small cut on the left side of your chest, between your ribs. They'll move your ribs aside to reach your heart.
Using a special CO2 laser guided by a computer, the doctor will create tiny passages in the left part of your heart. The number of passages (around 20 to 40) depends on your condition.
These new passages close up on the outside of your heart, but they stay open inside. They help the heart get more oxygen-rich blood.
The computer-guided laser will work when your heart is resting between beats, which prevents electrical issues.
Since your heart keeps beating during the procedure, there's no need for a machine to help with your heart and lungs.
Studies suggest that TMR encourages the growth of new blood vessels and gets rid of nerve fibers that cause chest pain.
Finally, the doctor will use stitches to close the cut and cover it with a bandage.
Post-surgery Care:
After TMR, you'll go to a recovery room. A nurse will check your vital signs, like your heart rate.
You might feel some pain, tenderness, and bruising where the cut was made. You'll get medicine to help you feel better.
You'll be given instructions on how to care for the cut and how to keep it clean and dry while it heals.
For some time, avoid heavy activities and lifting heavy things more than 10 pounds.
It's important to take all your prescribed medications and make a few lifestyle changes like quitting smoking, regular exercise, staying a healthy weight, and eating well.
You may be able to do your usual activities after about a month. But going back to work might take a couple of months, depending on your job.
Risks and Problems:
Like any surgery, TMR might have some risks, such as bleeding, scarring, infection, allergic reactions to anesthesia, damage to nearby tissues, and the chance of blood clots or DVT.
