Structural Heart Clinic

The philosophy of the Structural Heart Clinic mirrors the integrated team approach taken by the rest of the departments at the SDHC. Guests of the clinic will receive a multi-disciplinary approach to designing their care plan. They will meet with a cardiothoracic surgeon and an interventional cardiologist in the same office visit.

Heart Valve Procedures

With advanced minimally invasive therapies, our Structural Heart Clinic at South Denver Cardiology arranges care around four different heart valve procedures.  The Transcatheter Aortic Valve Replacement (TAVR) procedure is for patients that need to have their aortic valve replaced because they’ve developed a condition known as severe aortic stenosis, are a poor candidate for surgery and have symptoms related to the bad valve.  MitraClip is a procedure that can help patients with moderate-severe mitral regurgitation, which might not do well with open-heart surgery.  Left Atrial Appendage Occlusion procedures can minimize stroke risk for patients that can’t tolerate being on blood thinners for the long-term. Patent Foramen Ovale (PFO) closure can help reduce future stroke risk in certain patients by closing a hole between the two upper chambers of the heart.

The Structural Heart Clinic allows guests will be able to set up any supporting care, diagnostic testing, or follow up with the same doctors and nurses in the same location.

Aortic Valve Disease

The Structural Heart Clinic at the South Denver Heart Center (SDHC) specializes in the diagnosis and treatment of severe Aortic Stenosis.

This approach to patient care gets everything a guest of the SDHC will need in one place. They will be able to discuss treatment options that may include surgical, medication, or the groundbreaking Transcatheter Aortic Valve Replacement (TAVR) program. TAVR is a procedure that is performed through a catheter that is inserted into the patient’s groin, which provides treatment for patients with aortic stenosis considered too high of a risk for open-heart surgery. The procedure is similar to a cardiac stent. Instead, a stent-like device is deployed across the aortic valve creating a wider opening. TAVR received FDA approval in the fall of 2011. The physicians of the South Denver Heart Center, in collaboration with Colorado Cardiovascular Surgical Associates, can offer their patients this groundbreaking technology.

In this video, Dr. Lee MacDonald, an interventional cardiologist at South Denver Cardiology, discusses aortic valve disease and the use of TAVR.

Mitral Valve Disease

Mitral regurgitation is the most common heart valve disorder in the United States. Mitral regurgitation is a condition when the leaflets of the valve do not close properly, and blood flows backward into the upper chamber. Over time, this condition can not only create symptoms but also produce abnormal heart rhythms, clots, or, in many cases, heart failure. The usual treatment for mitral regurgitation is open-heart surgery to repair or replace the leaky valve. However, surgery is not for everyone. When open-heart surgery is too risky, the MitraClip device may be a good alternative. During this procedure, physicians thread a catheter from the leg to the heart and place a MitraClip device to decrease the backflow of blood. This clip allows the mitral valve to close more completely, helping to restore normal blood flow to the heart. Often, many times patients go home the next day. Multiple studies have shown that the MitraClip has been a safe and effective technique helping many patients who were once considered high-risk surgical patients.

In the video below, learn more about mitral valve disease and the treatment of mitral regurgitation with the MitraClip.



Left Atrial Appendage Occlusion: (Treatment for A-fib patients)

South Denver Cardiology Associates is pleased to offer our patients a new and innovative treatment for non-valvular atrial fibrillation (AFib). Until now, patients with this condition have relied on blood thinners or anticoagulants, such as Warfarin, to help manage their risk of stroke. While active, these medications can cause undesired side effects.

Now there is an alternative – the WATCHMANTM Implant.

This permanent implant may reduce stroke risk for a lifetime in people with AFib not caused by a heart valve problem. What’s more, WATCHMAN can reduce the risk of bleeding that comes with Warfarin (also known as Coumadin®) and eliminates the regular blood tests and food-and-drink restrictions that come along with it.

In a clinical trial, 9 out of 10 people were able to stop taking Warfarin just 45 days after the WATCHMAN procedure.

The one-time procedure is performed by the Cardiologists with South Denver Cardiology. Once implanted, it does not require replacement. The procedure takes about one hour, and patients typically go home the next day.
