For most of the last century, fixing a damaged heart valve meant open-heart surgery. Today, a remarkable family of treatments called structural heart interventions can repair or replace valves through small catheters threaded into the heart, often without opening the chest at all. For many patients, especially those who are older or higher risk, these procedures have transformed what is possible.
If your physician has mentioned TAVR or another catheter-based valve treatment, this overview will help you understand what these procedures are, who they are for, and what questions to ask before choosing a path.
What Are Structural Heart Interventions?
Structural heart interventions are procedures that fix problems with the heart's physical architecture, its valves, walls, and chambers, using catheters rather than traditional surgery. A catheter is a thin, flexible tube that an interventional cardiologist guides into the heart, usually through a blood vessel in the leg. Working through that tube, the physician can deliver a new valve, clip a leaking one, or close an abnormal hole, all while the heart keeps beating.
The appeal is straightforward. Because there is no large chest incision and no need to stop the heart, recovery is typically faster and gentler than open surgery. For patients who would face high risk from a major operation, these techniques can offer treatment that once would have been out of reach.
TAVR: Replacing the Aortic Valve Without Open Surgery
The best-known structural heart procedure is TAVR, which stands for transcatheter aortic valve replacement. It treats aortic stenosis, a condition in which the aortic valve, the main outflow valve of the heart, becomes stiff and narrowed. Severe aortic stenosis causes breathlessness, chest pressure, fainting, and, if left untreated, can be life-threatening.
In TAVR, the cardiologist guides a collapsed replacement valve, mounted on a catheter, up to the diseased valve. Once in position, the new valve is expanded and immediately takes over the job of the old one, which is pushed aside. The whole procedure often takes a fraction of the time of open surgery, and many patients go home within a day or two.
TAVR or surgery? It depends.
TAVR was first offered to patients too sick for open surgery, then to those at high risk, and over time to lower-risk patients as well. But it is not automatically the right choice for everyone. The decision between TAVR and surgical valve replacement depends on a patient's age, anatomy, other heart conditions, and how long the valve needs to last. This is a genuine judgment call, and it is exactly the kind of crossroads where a cardiac second opinion is most valuable.
How candidacy is determined
Before any structural heart procedure, you will undergo careful imaging, usually a detailed CT scan of the heart and blood vessels along with an echocardiogram. These images tell the team the exact size and shape of your valve, the condition of the arteries the catheter must travel through, and whether the surrounding anatomy is suited to a device. Two patients with the same diagnosis can have very different anatomy, and that anatomy often decides which approach is safest. A thorough review of these images is one of the most important steps, because a recommendation built on incomplete or hastily read imaging can point a patient toward the wrong procedure.
Most reputable programs make these decisions through a team that includes both interventional cardiologists and cardiac surgeons. That collaborative model exists precisely because no single specialty has the full view. When you seek an outside opinion, you are asking for that same balanced perspective, applied independently to your own case.
Other Structural Heart Procedures
TAVR is the most familiar, but it is part of a larger toolkit. Other structural interventions include:
- Transcatheter mitral and tricuspid repair. For leaking valves on the other side of the heart, devices can be delivered by catheter to clip or reshape the valve and reduce the leak.
- Left atrial appendage closure. For patients with atrial fibrillation who cannot tolerate long-term blood thinners, a small device can seal off the pouch where stroke-causing clots tend to form.
- Closure of holes between heart chambers. Certain congenital openings can be closed with a catheter-delivered device rather than surgery.
Each of these has specific criteria, and matching the right patient to the right procedure is where expertise matters most.
Weighing the Trade-Offs
Less invasive does not always mean better for every individual. Catheter-based valves, for instance, have an excellent track record, but the question of how a particular valve choice will serve a younger patient over many decades is one that deserves careful discussion. Likewise, anatomy sometimes favors a surgical approach. The point is not that one method is superior across the board, but that the choice should be tailored to you.
Recovery is another part of the trade-off worth understanding clearly. Catheter-based procedures generally offer a faster, gentler recovery, often a hospital stay of a day or two and a quick return to normal activity. That is a genuine advantage, particularly for older patients or those with other health problems. At the same time, every device requires lifelong follow-up, including periodic imaging to confirm it continues to function well, and some require specific medications afterward. A sound recommendation accounts not only for the procedure itself but for the years that follow it, including how a chosen valve or device fits into the rest of your life and your other conditions.

Why a Combined Review Matters for Structural Heart Decisions
Few decisions in cardiology benefit more from two viewpoints than the choice between a catheter-based and a surgical approach. That is why WhiteGloveMD reviews every case with a cardiac surgeon and a cardiologist together, a dual-physician Heart Team. The interventional cardiologist understands the catheter-based options in depth; the surgeon understands when an operation is the wiser path. Reviewed together, your case gets a balanced, complete recommendation rather than one shaped by a single specialty's lens.
A second opinion here is not about distrust. It is about making sure that, among an expanding set of impressive options, you are guided to the one that truly fits your heart and your life. See how our review works to understand the process.
