Unlike a classic operation, minimally invasive surgery (also known as minimally invasive surgery or minimally invasive surgery) does not involve opening the chest by cutting the sternum. In addition, it does not require stopping the heart or the use of an artificial heart-lung, a pumping device responsible for circulating blood through the body so that it can continue to receive blood rich in oxygen.
The surgeon monitors the heart on a video screen and operates using long-handled instruments including open heart surgical instrument set inserted into small incisions. In some cases, a robotic arm is used. Minimally invasive valve repair and replacement is appropriate in some cases of heart valve disease, but not performed in all hospitals. This type of procedure is also called endoscopic or robotic heart surgery.
Transcatheter Aortic Valve Implantation (ITVA), or Catheter Aortic Valve Implantation, is a valve replacement surgery that aims to treat symptomatic aortic valve stenosis in a different way from the conventional method. On the one hand, rather than opening up the entire chest, AVIA is done through small incisions in the groin or chest. On the other hand, rather than repairing, or removing and replacing the damaged aortic valve, a new valve is implanted directly on it.
The surgeon inserts a collapsible valve into the body using a catheter through a small incision in the groin or chest.
Through ultrasound and x-ray, the catheter is delivered to the right place in the heart, and the new valve is unfolded for proper implantation.
As soon as it is in place, the new valve begins to regulate blood flow.
Typically, patients with AVIT recover faster and stay in hospital for less time after surgery (about three to five days) than those undergoing open heart surgery.
LATI is recommended for people at high risk of complications from open heart surgery. The healthcare team assesses each patient’s symptoms and overall health to determine if the AVI is right for them.
What to expect?
Before the intervention
If you smoke, you are strongly advised to stop at least two weeks before the procedure, as smoking can lead to blood clots and breathing problems.
About a week before the procedure, you will be asked to go to the hospital’s pre-admission unit. You will be explained the risks and benefits of the procedure, and you will have to sign a consent form. Preoperative tests include:
The Electrocardiogram (ECG);
If one or more of the following apply to you, please let your healthcare team know:
You have ever had a reaction to a contrast agent or to iodine, or you have ever suffered from a severe allergic reaction (insect bite, seafood, etc.).
- You have asthma.
- You are allergic to any medicine.
- You have bleeding problems or you are taking medicines to thin the blood (anticoagulants).
- You have a history of kidney problems or diabetes.
- You have one or more piercings in your chest or abdomen.
- Your health has recently changed.
- You are or might be pregnant.
Most patients are admitted to the hospital the day before the procedure. The night before, you will be asked to wash and disinfect your skin. Here are other preparations for the intervention:
To reduce the risk of vomiting while you are under anesthesia, you will be asked to refrain from eating or drinking after midnight the day before the procedure;
The area targeted by the operation will be cleaned with an antiseptic product;
Your chest hair will be shaved, if necessary.
During the intervention
If you are due to have surgery, you will be under general anesthesia and will therefore be asleep throughout the operation.
In a classic procedure, your heart will be temporarily stopped to operate on the defective valve (s). You will be connected to an artificial heart-lung.
The procedure will take at least two hours, depending on the number of valves to be repaired or replaced.
You will regain consciousness in a recovery room or in the intensive care unit.
You will likely stay in the hospital for about a week.
How quickly you will recover from this procedure depends in part on your condition before the surgery.
In the case of minimally invasive surgery, your heart will not be stopped; you will not need an artificial heart-lung; and your hospital stay will likely be shorter and your recovery faster than if you had a conventional operation.
