OR-Live.Com Presents: Early Intervention in the Treatment of Mitral Valve Disease: Clinical Guidelines, Treatment Options &Amp; Patient Benefits
The Cleveland Clinic and Intuitive Surgical, Inc. will present a live webcast on OR-Live.com featuring a roundtable discussion on the treatment of asymptomatic mitral valve disease. Moderator Julie Huang, M.D., staff cardiologist in the Section of Clinical Cardiology, Department of Cardiovascular Medicine; Brian P. Griffin, MD, FACC, staff cardiologist in the Section of Cardiovascular Imaging, Department of Cardiovascular Medicine; A. Marc Gillinov, MD, staff cardiac surgeon; and Tomislav Mihaljevic, MD, staff cardiac surgeon, Department of Thoracic and Cardiovascular Surgery -- all of the Cleveland Clinic Heart and Vascular Institute -- will discuss mitral valve prolapse, treatment options and surgery guidelines for asymptomatic patients. Following this discussion, the panel will conduct a live question and answer session with viewers.
According to the latest guidelines from American Heart Association and American College of Cardiology, select patients qualify for early surgical intervention to treat mitral valve regurgitation. At the Cleveland Clinic, a recognized leader in treatment of valvular heart disease, surgeons are able to repair more than 99% of mitral valve prolapse using da Vinci Mitral Valve Repair, a minimally invasive, sternum-sparing procedure. The procedure is performed using the da Vinci Surgical System, the world's only commercially available robotic platform for complex, minimally invasive surgery.
"Robotically assisted mitral valve repair is the best and least invasive treatment for the majority of patients with a leaky mitral valve," said Dr. Mihaljevic. "Compared to valve replacement, mitral valve repair provides better long-term survival, better preservation of heart function, lower risk of complications, and usually avoids the need for long-term use of blood thinners (anticoagulation)."
About the Condition
In patients who have mitral valve prolapse, the tissue of the mitral valve leaflets and chordae are abnormally stretchy, so that as the heart beats to circulate blood, the mitral valve bows or flops back into the left atrium. Many patients with mitral valve disease are asymptomatic (have no symptoms), even with a leak that is severe. When symptoms develop, they include shortness of breath, fatigue, loss of energy, swelling of the ankles and palpitations (extra or skipped heart beats).
Most patients diagnosed with mitral valve disease do not have any leaking (regurgitation) and do not require surgery. However, in about 10 to 15 percent of people with mitral valve prolapse, there is a substantial leak and, surgery should be considered.
Surgeons can either replace the valve with a mechanical or biological valve, or they can repair it using the patient's own tissue. Studies demonstrate that valve repair, which is facilitated by the da Vinci System, offers patients significant potential advantages over valve replacement. These advantages include reduced risk of surgical complications,(1) a higher long-term survival rate,(2)(3)(4)(5) improved function and strength of the heart,(1) more freedom from re-operation, fewer post-surgical complications,(1) no need for life-long blood thinner medication and a shorter hospital stay.(1)
In the US alone, about 40,000 people have surgery to treat mitral valve regurgitation each year.(6) In 2006, Cleveland Clinic surgeons performed 2,127 valve procedures -- 1,524 primary operations and 603 re-operations, the largest number of valve procedures in the U.S.
According to Drs. Gillinov and Mihaljevic, leaky mitral valves can be repaired rather than replaced in approximately 99% of patients, and nearly 100% of patients receive a minimally invasive procedure if mitral valve prolapse is the cause of the leak.
"When a patient requires isolated mitral valve surgery for a degenerative valve, at Cleveland Clinic we can perform the operation robotically or using other minimally invasive techniques in nearly all cases," Dr. Gillinov said. "We offer several different minimally invasive approaches, including robotically assisted procedures, a small incision on the right chest, or a small incision in the mid-line. Expertise with several approaches enables us to determine the best procedure for each patient, optimizing results."
About the Treatment
During traditional heart valve surgery, a surgeon will make an incision down the center of your sternum (breastbone) to get direct access to your heart. The surgeon then repairs or replaces your abnormal heart valve or valves. While this approach remains in use, today most patients with isolated valve disease can be treated with minimally invasive techniques. Minimally invasive surgery is a type of surgery performed through smaller incisions. This type of surgery reduces blood loss, trauma, and length of hospital stay. There are two types of heart valve surgery: valve repair surgery and valve replacement surgery. Valve repair allows the surgeon to fix your faulty heart valve, often without the use of artificial parts. The advantages of heart valve repair include a lower risk of infection, decreased need for life-long blood thinner medication and preserved heart muscle strength. The mitral valve is the most commonly repaired valve, but the aortic and tricuspid valves may also undergo some of these repair techniques.

About the da Vinci(R) Surgical System
The da Vinci Surgical System is a sophisticated robotic platform designed to enable complex surgery using a minimally invasive approach. The da Vinci System consists of an ergonomic surgeon's console, a patient-side cart with four interactive robotic arms, a high-performance vision system and proprietary EndoWrist(R) instruments. Powered by state-of-the-art robotic technology, the da Vinci System is designed to scale, filter and seamlessly translate the surgeon's hand movements into more precise movements of the EndoWrist instruments. The net result is an intuitive interface with breakthrough surgical capabilities. By providing surgeons with superior visualization, enhanced dexterity, greater precision and ergonomic comfort, the da Vinci Surgical System makes it possible for more surgeons to perform minimally invasive procedures involving complex dissection or reconstruction. This ultimately raises the standard of care for complex surgeries, translating into numerous potential patient benefits, including less pain, a shorter recovery and quicker return to normal daily activities.
