Stent or bypass surgery?
Reviewed on July 17, 2026
When exams show significant blockages in the heart's arteries, one of the most common questions is: place a stent or have bypass surgery? Both approaches share the same general goal, which is to improve blood supply to the heart, but they work in different ways and have their own indications. There is no single answer that fits everyone, and the decision is usually made together by a team, considering many details of your case. This article explains, in a general and educational way, the differences between these options.
Two ways to treat blockages
Angioplasty with a stent opens the narrowed artery from the inside, using a catheter and a small metal mesh, without the need for open surgery in most cases. It is a less invasive procedure.
Bypass surgery, or revascularization, creates new paths for blood to go around the blockages, using the patient's own vessels. It is a larger operation, with a longer recovery.
What usually weighs on the choice
The decision takes into account the number and location of the blockages, the presence of diabetes, heart function, age and other health conditions. Each approach tends to be more suitable in certain scenarios.
The patient's preferences and the risks and benefits of each option are also part of the conversation. That is why two cases that seem similar can lead to different decisions.
Still unsure about your case?
Send your exams and your case history and receive a structured, written opinion from an independent specialist physician.
Request a second opinionThe team decision
In many complex cases, the choice between stent and surgery is discussed by a group that brings together different specialists, often called a heart team. This joint assessment helps balance the different points of view.
This format recognizes that there is no automatic decision. The goal is to reach the best recommendation for that specific patient, based on evidence and the team's experience.
Why a second opinion helps
Precisely because it involves delicate choices with no single answer, this is one of the situations where many people feel unsure. Understanding the reasons behind the recommendation makes a difference.
An independent second opinion can review the exams, confirm the proposal or bring another perspective on stent, surgery or medical treatment, helping you decide with more peace of mind.
Frequently asked questions
Is a stent always better because it is less invasive?
Not always. Although it is less invasive, in some scenarios surgery may offer benefits that a stent does not. The best option depends on the combination of factors in your case, assessed by the team.
Can I take part in the decision between stent and surgery?
Yes. Your questions, values and preferences are an important part of the conversation. The team explains the options, risks and benefits, and the decision is ideally shared between you and the professionals.
How do I submit my case for a second opinion on Revidra?
You can upload the catheterization report and your other heart exams through the Revidra platform. An independent specialist reviews the material and returns a structured written opinion about the options of stent, surgery or medical treatment.
