Cardiac Clinic Tour: Dr. Scott Lim Extends MitraClip Competence At The University Of Virginia

As many of you know, I’m fascinated with technology.

That said, when I’m invited to see a clinical application of a new heart valve technology, I jump at the opportunity. So, last week, I found myself in a hybrid catheterization laboratory / operating suite at the University of Virginia in Charlottesville, Virginia. Dr. Scott Lim, Associate Professor of Pediatrics and Medicine, Division of Cardiology, was performing a MitraClip procedure.

“We’ve been investigating the MitraClip therapy in select patients as an alternative, less-invasive therapy for mitral regurgitation,” Dr. Lim shared with me. “By clipping the mitral leaflets into a double-orifice configuration we can reduce leakage across the valve – without inducing stenosis.”

 


While the MitraClip is commercially available in Europe, the device has yet to receive FDA approval in the United States. Abbott Laboratories, the manufacturer of the MitraClip, submitted results from its EVEREST trial to the FDA in March, 2010. Reports suggest that FDA approval could occur in 2011. Until then, only 20 MitraClip procedures are performed each month in the United States — under the FDA’s ongoing access protocol.

Thus far, Dr. Lim has performed over 60 MitraClip procedures. That positions him as one of the most experienced interventional cardiologists with this technology. Only Dr. Saibal Kar, at Cedars-Sinai Hospital in Los Angeles, has performed more MitraClip procedures.

As I observed Dr. Lim with his medical team and patients, my assumption about this married, father of two, was confirmed… Dr. Lim is an incredibly nice guy who prefers to be called “Scott” not “Dr. Lim”.

I also found Dr. Lim to be a straight shooter about the opportunities and constraints of this percutaneous technology.

“While the MitraClip appears to be a viable option for mitral regurgitation treatment, I believe we, the physicians, need to ensure that only the right patient gains access to its clinical use at this point in its development. Other patients may be better served by the more traditional, open-heart surgical approaches to treat mitral valve disease.” — Dr. Scott Lim

During the procedure, I continued to learn more about the MitraClip and its unique delivery system. I was intrigued by the way in which Dr. Lim and Dr. Gorav Ailawadi, Assistant Professor of Cardiac Surgery, manipulated the controls of the MitraClip’s delivery system in front of an 8-screen display panel.

During the hour-long procedure, Dr. Lim and Dr. Ailawadi shared the controls of the MitraClip and engaged in a lively discussion about positioning the device in the patient’s beating heart. On their 2nd attempt at ‘clipping’ the mitral leaflets, real-time echocardiogram results illustrated a significant improvement in reducing the patient’s mitral regurgitation.

“With this device, we’re able to evaluate results and then adjust if needed,” Dr. Lim said to me. “On our first attempt, the posterior leaflet wasn’t sitting as it should. So, we repositioned the MitraClip to achieve a better outcome.”

According to reports, the MitraClip delivery system (shown below) offers physicians eight different planes of movement to maneuver the clip through the patient’s vascular system and heart.

“We got a good result today,” Dr. Lim shared with me as the case came to a close. “The patient’s mitral regurgitation decreased from a 3-4 to a 1-2 level. And, we can discharge him tomorrow.”

Thanks to Dr. Lim, Dr. Ailawadi and the entire team at The University of Virginia Health System in Charlottesville for providing me such an incredible opportunity!

Keep on tickin!
