Modern vascular treatments like balloon angioplasty vs stent have made it possible to restore circulation with minimally invasive procedures, as cardiovascular diseases often result from narrowed or blocked arteries that limit blood flow to the heart.
While both aim to open the artery, the difference between stent and balloon lies in how each maintains vessel patency over time. Understanding ballooning vs stenting helps doctors choose the most effective approach for each patient’s condition and long-term heart health.
What Is The Difference Between Stent And Balloon?
While ballooning vs stenting are often performed together, the choice between them involves several critical considerations:
- Procedure Complexity: Balloon angioplasty is a straightforward process of inflating a balloon to widen the artery.
- Longevity of Results: One of the main factors in the Balloon Angioplasty vs Stent comparison is the durability of the results.
- Risk of Restenosis: Restenosis is a key concern when comparing Balloon Angioplasty vs Stent.
- Long-Term Implications: Balloon angioplasty might require repeated interventions if restenosis occurs.
Balloon Angioplasty Vs Stent Which Is Better?
When comparing Balloon Angioplasty vs Stent, the choice depends largely on the patient’s condition and the severity of the artery blockage. The main difference between stent and balloon lies in how each treatment keeps the artery open.
Balloon angioplasty uses a small balloon to widen the artery temporarily, improving blood flow immediately. However, without additional support, the artery might narrow again over time.
In contrast, a stent, a tiny mesh tube, is often placed after balloon angioplasty to keep the artery open for the long term. Modern drug-eluting stents have made this approach more effective, as they reduce the risk of re-narrowing and the need for repeat procedures.
So, Balloon Angioplasty Vs Stent Which Is Better? There isn’t one single answer for everyone. For minor or flexible blockages, balloon angioplasty alone may be enough. But in most cases, stents provide more lasting results and better long-term blood flow, especially for patients with more complex heart conditions.
How Balloon Angioplasty Works?
Balloon angioplasty is a common heart procedure that helps open blocked or narrowed arteries and restore normal blood flow. It’s often used to treat coronary artery disease or Blockage of arteries in legs and is one of the main methods discussed when comparing Balloon Angioplasty vs Stent treatments.
During the procedure, a thin flexible tube called a catheter is inserted through a small cut in the wrist or groin. The doctor carefully guides it through the blood vessels until it reaches the blocked part of the artery. At the tip of the catheter, there’s a small balloon. When the balloon reaches the blockage, it’s gently inflated to push the fatty buildup against the artery walls. This widens the artery and allows blood to flow more easily.
Sometimes, after the artery is opened, the doctor places a small metal mesh called a stent to keep it open. The stent and balloon difference lies in their purpose: the balloon opens the artery, while the stent keeps it open for longer.
In simple terms, both the balloon and stent work to improve blood flow, but each serves a slightly different role. Understanding balloon vs stent helps explain why some patients only need angioplasty, while others may require a stent for lasting support.
Types and Functions of Stents
Stents are small, mesh-like tubes that are placed inside an artery to keep it open after it has been widened by balloon angioplasty.
The choice between Balloon Angioplasty vs Stent often depends on the type of stent used and the specific needs of the patient.
The primary types of stents include:
- Bare-Metal Stents (BMS): The first type of stent developed, bare-metal stents are made from stainless steel or cobalt-chromium alloys. These stents act as a scaffold to keep the artery open after angioplasty. However, they do not address the issue of restenosis, the re-narrowing of the artery due to tissue growth around the stent.
- Drug-Eluting Stents (DES): These stents are coated with medication that is gradually released into the artery wall to prevent scar tissue from forming, which significantly reduces the risk of restenosis.
- Bioabsorbable Stents: Also known as bioresorbable scaffolds, these stents are made from materials that naturally dissolve in the body over time. This innovation is particularly relevant in the Balloon Angioplasty vs Stent discussion, as it offers a solution with potentially fewer long-term complications.
- Dual Therapy Stents (DTS): Combining the benefits of drug-eluting and bioabsorbable stents, dual therapy stents release medication while also gradually dissolving.
These stents aim to offer both immediate support and long-term safety, representing an advanced option in the ongoing Balloon Angioplasty vs Stent debate.
Balloon Angioplasty Pros And Cons
In the Balloon Angioplasty vs Stent evaluation, balloon angioplasty offers several advantages, but it also comes with notable limitations:
Pros:
- Less Invasive: Balloon angioplasty has therefore been considered less traumatic than other interventions such as CABG and it is also associated with shorter hospital stay and a reduced incidence of complications from surgery.
- Immediate Relief: The process offers an immediate end of the pain resulting from coronary artery illness like chest pain or anguish and shortness of breath, something which may otherwise be fatal.
- Simplicity: In cases where the blockage is minor, then angioplasty using the balloon is enough to relieve blockage hence abandoning the use of stents with their complications.
- Versatility: This feature of balloon angioplasty makes it a very versatile tool in cardiovascular interventionist’s arsenal as it can be used to treat blockages in arteries all over the body and not only in the coronary arteries.

Cons:
- Higher Restenosis Risk: If one does not use a stent to contain the artery it can again close up which could necessitate more procedures.
- Temporary Solution: This method does not guarantee to cure the patients with severe or multiple blockages, and the patients may experience a recurrence of the symptoms after the treatment.
- Limited Efficacy in Complex Cases: Even in cases where there are very severe calcium deposits or multiple blockages in the arteries, simple use of the balloon angioplasty may not be enough– that is why the stent is used.
Stents Pros And Cons
Stenting, often discussed alongside balloon angioplasty in the Balloon Angioplasty vs Stent debate, offers a more permanent solution but also comes with its own set of considerations:
Pros:
- Reduces Restenosis: Stents, particularly drug-eluting stents, significantly reduce the risk of restenosis by keeping the artery open and releasing medication that prevents tissue growth.
- Long-Term Efficacy: Stenting provides a durable solution, especially in complex cases or when multiple arteries are affected, reducing the need for repeat procedures.
- Advancements in Technology: The development of bioabsorbable and dual therapy stents has improved patient outcomes by offering temporary support without leaving a permanent implant.
- Broad Applicability: Stenting is effective in a wide range of patients, including those with diabetes or other conditions that make restenosis more likely.
Cons:
- Risk of Stent Thrombosis: Although stenting reduces restenosis, it introduces the risk of stent thrombosis, which can lead to a heart attack if not managed properly with antiplatelet medications.
- Lifelong Medication: Patients with stents often need to take blood-thinning medications for an extended period, which increases the risk of bleeding and other complications.
- Procedure Complexity: Stenting adds complexity to the procedure, with a slightly higher risk of complications during and after the intervention.
- Cost: Stenting, particularly with drug-eluting stents, is more expensive than balloon angioplasty alone, both in terms of the procedure and the ongoing cost of medication.
Conclusion About Balloon vs Stent
Choosing between Balloon Angioplasty vs Stent is one of the most important decisions in treating coronary artery disease. While ballooning offers a less invasive and quicker procedure, it sometimes requires follow-up treatments because of the higher chance of restenosis. On the other hand, stenting provides a more lasting solution.
Understanding the real difference between ballooning vs stenting helps patients choose the treatment that best supports their heart health and long-term recovery.

FAQs
Which is better, balloon angioplasty or stent?
Neither is universally “better” ; it depends on the patient’s condition. Balloon angioplasty is ideal for short or simple blockages and is less invasive, but the artery can narrow again later. Stenting, on the other hand, offers more lasting results by keeping the artery open with a metal mesh. Doctors often combine both to ensure stable blood flow and reduce the chance of re-narrowing.
Why balloon angioplasty without stent?
Sometimes, doctors choose balloon angioplasty without a stent when the blockage is small, in a large artery, or near a branch where placing a stent may be risky. It can also be preferred for patients who can’t take long-term blood-thinning medications. In these cases, the balloon alone can restore enough blood flow safely.
What are the disadvantages of balloon angioplasty?
The main downside of balloon angioplasty is that the artery may narrow again over time, a condition called restenosis. There’s also a small risk of damaging the artery wall or forming a blood clot at the treated site. Because of this, many patients benefit more from adding a stent to keep the artery open longer.
Which type of angioplasty is best?
The best type of angioplasty depends on the type and location of the blockage, as well as the patient’s overall health. For many people, stent-assisted angioplasty gives longer-lasting results. However, for others with mild narrowing or specific conditions, balloon angioplasty alone may be safer and effective. The decision is always personalized by a vascular or heart specialist.
