Procedure in Minimally Invasive Mitral Valve Repair is First for the Hospital
BALTIMORE—A team at MedStar Union Memorial Hospital and the MedStar Heart & Vascular Institute in September successfully clipped together the two flaps of a patient’s leaky mitral value using the MitraClip, a device that may soon be approved by the Food and Drug Administration for use in many more patients.
The MitraClip offers a way to repair a mitral valve without open heart surgery. The device is implanted by accessing the patient’s heart through a vein in their groin.
“This is just one of many transformational technologies that MedStar Union Memorial is now able to offer patients,” said John C. Wang, MD, chief of the Cardiac Catheterization Laboratory at MedStar Union Memorial and scientific director for Baltimore Cardiovascular Research. “We have patients that did not have surgical options and are now able to give them a new lease on life.”
Mitral valve regurgitation happens when the heart’s mitral valve doesn’t close tightly, allowing blood to flow backward into the heart. In severe cases left untreated, it can cause heart failure or heart arrhythmias. Symptoms include heart murmur, fatigue and shortness of breath.
In the 50-minute procedure performed Sept. 26, surgeons went in through the 79-year-old patient’s groin and through the inferior vena cava before clipping together the leaflets of the leaky mitral valve using the tiny MitraClip. The patient recovered well, went home the next day and was back at work within a few days.
Harold Dwin, the patient, said he was pleased with the outcome of the procedure and his recovery. He lived with a heart murmur for years before he found himself struggling on a hike at high altitude while on vacation in Idaho. When he returned from the trip, he was diagnosed with severe mitral valve regurgitation and sought out the heart specialists at MedStar Union Memorial Hospital.
“It changed my life enormously,” he said. “I had a serious heart condition that could have been fatal to me eventually.”
Many patients with mitral valve regurgitation are treated with open heart surgery; however some cannot undergo the procedure for various reasons. In Dwin’s case, surgeons thought open heart surgery might disrupt the six cardiac bypasses he had placed a couple decades ago. In those cases, the MitraClip is the less invasive option.
The MitraClip is currently approved for use in patients with degenerative mitral regurgitation. In September, researchers reported in a large clinical trial that the device was very effective in patients with another type of mitral valve problem – functional mitral regurgitation. Far more patients have functional mitral regurgitation than the degenerative type, and the study is expected to lead to FDA approval for the device in patients with the functional type of the disease.
