What is PTCA Guidewire and Why Do We Use Them?

Being a surgeon is one of the most demanding jobs in the world. Many don't know this, but handling different surgical tools and equipment is one of the most underrated abilities of a surgeon.

You can find more information on our web, so please take a look.

Surgeons handle an extensive array of surgical tools and instruments throughout their careers, numbering more than 200 in total. This represents a wide range of procedures and techniques that surgeons must possess to cope with the nature of their profession.

Also, medical practitioners must have the necessary skills to choose the best equipment and use them efficiently, as each tool and instrument serves a unique and critical purpose in the surgical process.

The wide range of surgical equipment and tools that are readily available to surgeons serves as a testament to the constant developments in medical technology and the significance of keeping up with the most recent methods and devices.

One such surgical instrument is the PTCA Guidewire, which is specially designed to perform operations on clogged coronary arteries. In this article, we’ll discuss what PTCA Guide wire entails and its many uses in the healthcare sector.

What is PTCA (Percutaneous transluminal coronary angioplasty) Guidewire?

PTCA, or Percutaneous transluminal coronary angioplasty, is a surgical procedure carried out to unclog the flow of blood into the arteries. The PCTA guidewire is a thin, flexible surgical wire designed to carry out the insertion of the catheter into the body.

As the name suggests, surgeons use guide wire as a guide in minimally invasive surgeries to help position and pilot the balloon dilatation catheter through the blood vessels to open up blocked coronary arteries in the body.

A high-quality guide wire guarantees patient safety when treating coronary artery disease.  Also, it saves time and energy when carrying out a surgical procedure. A quality guide wire plays a critical role in performing a successful surgical procedure.

Uses of PTCA guidewire

PTCA Guidewire has several uses, including:

Road guide to the artery

The guide wire is a medical device that serves as a pathway through which the catheter is safely threaded into the coronary artery. In other words, a guide wire allows you to easily gain access to the artery during surgery.

Navigate interventional devices  

Guidewire allows surgeons to easily move interventional devices, such as balloon catheters, stents, and atherectomy to the stenosis.  To medical practitioners, the guide wire is a means to navigate interventional medical devices through the body without causing any internal injuries to the patient.

Navigate through the blocked coronary artery

Because of their flexibility and size, Guidewire allows medical professionals to easily and safely navigate through a blocked or narrowed coronary artery without causing any internal injuries to the patient and restoring blood flow to the heart.

There are types of guidewires PTCA that can be used for coronary intervention. The success of the operation depends on the ability to manipulate the guide wire into and through coronary artery stenosis, as well as the ability of the guide wire as a subsequent device to deliver the track. The ideal guide wire can be easily twisted and manipulated through tortuous coronary arteries without causing trauma, but still provides sufficient rigidity for the delivery of relatively inflexible stents.

Now, almost all PTCA wires are 0.014 inches in diameter. Most operators will choose a general or "workhorse" line for most interventions. Provide "extra support", hydrophilic coating or tapered tip PTCA wire, which can be used for special situations, such as blood vessel bending, calcification and complete occlusion.

1. The PTCA guide wire is made of stainless steel or nitinol center shaft

Nitinol core wire is more resistant to kinking than stainless steel core wire, with a smaller torque response. Various coatings are "sprayed" or "dripped" onto the wires to reduce friction. The strength of the tip varies from wire to wire, resulting in a stiffer or softer spring coil tip.

The length of the core wire taper will also change the characteristics of the wire: if the PTCA guide wire core wire extends to the distal end, this will cause the wire tip to be harder than the core wire rapidly becomes thinner in front of the tip, providing the former with a crossover technical advantage. For chronic complete occlusion, the hydrophilic polymer coating tip reduces friction, making it easier to pass through highly narrow lesions and tortuous anatomical structures. However, this advantage comes at the cost of increasing the risk of line perforation and interlayer.

2. Torque response is an important feature of PTCA guide wire

Torque response refers to the rotation transmission from the operator to the tip of the PTCA guidewire. One-to-one torque response is desirable, and this feature is one of the most important features for doctors when choosing a wire. The core-to-tip structure improves torque control, and the specific taper design also affects the torque response.

It is not uncommon for devices to be challenging to deliver in curved, angled, and calcified blood vessels. In this case, starting with the "extra support" line, or replacing the "main force" line with the same line may also help, because the increased rigidity of the support line may allow the conveying device in situations where the "main force" line cannot be achieved. However, the additional support wire is unlikely to follow the path of the blood vessel and may cause wire bias, further hindering device delivery. In addition, advancing the second wire (the "buddy wire") may help straighten the zigzag section and facilitate the delivery device.

Both of these techniques can significantly correct previously highly angled coronary arteries, leading to the development of so-called "pseudo-lesions". These should not be mistaken for true stenosis. Once the natural blood vessel angle is restored, withdrawing the guide wire at the proximal end of the bend will confirm that these are not true lesions.
