  • Stenting


Catheterization is a cardiac test done to look at the blood flow by way of coronary arteries, and is done prior to stenting. The process helps cardiologists recognize blockages in arteries, which could lead to atherosclerosis, and study the performance of valves. Catheterization is generally done before a cardiac surgery to get a coronary angiogram or an x-ray image of the arteries. This angiogram makes it simple to identify the condition of a person's heart and focus on problem areas while in the surgery.

What is Catheterization?

In the process of catheterization, individuals have to lie on a table, under an x-ray machine. The groin area, which is often used for the placement of catheter, will then be anesthetized and a cut is made to gain access to a blood vessel. This cut can be used to put in the catheter or a slim tube which is threaded to the artery from your blood vessel. During this process, doctors are led by an imaging screen which shows the position and advancement of the catheter within the body. Once it gets to the heart, the catheter is used to insert a special dye into the arteries. This dye can be viewed in the x-rays and helps cardiologists in taking a more detailed look at the blockages in heart.

What is Stenting?

Stenting is a procedure that comes after catheterization during an angioplasty. It gets its name from a crimped mesh tube referred to as a stent which is put into blocked and narrowed coronary arteries for their dilation which leads to easy flow of blood through them. During coronary stenting, a catheter having a deflated balloon at its tip is put through the cut into the blood vessel. The deflated balloon contains a stent wrapped around it. Upon hitting the specific artery, the catheter is utilized to fill the balloon. While the balloon inflates and helps improve the area within the artery, the stent on the balloon stretches and gets connected to the walls. When the stent is positioned successfully, the balloon is deflated and the catheter is retrieved. The placement of a stent helps to ensure that it'll prevent the artery from getting narrowed or clogged again later on.

Why Do I Need Stenting?

Patients struggling with coronary heart diseases and extreme cholesterol levels resulting in blockage might find stenting very effective and tremendously hassle free when compared with complicated surgical treatments. Occasionally, stents are covered in medicines which are released into the heart to help ease its functioning.

The duration of catheterization isn't more than one hour, but stenting might take around three hours, depending on the intricacies of a case.
