Best PTCA Guide Wires for Coronary Intervention

In this article, we will educate you on how to choose the best guide wire to use for coronary intervention.

Different types of PTCA guide wires can be used for the surgical process known as Coronary Intervention.

The success of the operation is determined by the ability of surgeons to manipulate the PTCA guide wire into the stenosis of the coronary artery as well as the ability of the PTCA guide wire to function as a subsequent device that can track the location of coronary artery stenosis.

Now, virtually all PTCA guide wires have a diameter of 0.014 inches. Most surgeons select a general or "workhorse" line for coronary intervention. They then provide extra support in form of a tapered tip PTCA wire or hydrophilic coating, which can be used in special conditions including calcification, blood vessel bending, or complete occlusion.

Choosing the best PTCA guide wires

Selecting the best PTCA guide wire may be challenging, however, considering certain factors can help you in making a wise choice.

The best PTCA guide wire is made of nitinol center shaft

PTCA guide wires made of nitinol core wires are often more resistant to kinking compared to those made of stainless steel core wires. Thus, Nitinol core wires have a greater core response.

The guide wires made of Nitinol are dripped or sprayed with hydrophilic polymer coatings to reduce friction. The tip of the guide wire is strong making the spring coil tip stiffer.

However, the length of the core wire taper varies and this has a significant impact on the characteristics of the guide wire. If the core of the PTCA guide wire extends to the distal end, it results in the hardened tip of the wire while the core of the wire becomes softer and thinner. In this case, the wire tip has a higher technical advantage.

If there's a complete blockage in a blood vessel, the hydrophilic polymer coatings on the guide wire enable it to pass through tortuous anatomical structures and narrow lesions. Nevertheless, there's an increase in the risk of line perforations.

The best PTCA guide wire has a quick torque response

Torque response is a measure of the transmission of rotation from an operator to the tip of a PTCA guide wire. A quick torque response is preferable, and it's one of the most important factors considered by medical doctors and surgeons before choosing a guide wire.

A guide wire with a quick torque response makes it easier for operators to deliver in calcified, curved, and angled blood vessels, which may be challenging to carry out using a guide wire with a slow torque response.
