(HealthDay News) --
A new method of repairing leaking mitral heart valves appears safe, a small
study shows.
In the new study, researchers tested a reversible implant called the Percutaneous Transvenous Mitral Annuloplasty (PTMA) system, which is installed via a catheter.
In the heart, the mitral valve controls the flow of blood from the left atrium into the left ventricle (from the upper left chamber into the lower left chamber). A leaking mitral valve causes blood to flow back into the left atrium. This condition can worsen existing heart failure or cause congestive heart failure, according to a news release from the American Heart Association.
Currently, mitral valve repair requires opening the chest and putting the patient on a heart-lung machine. This method increases the risk of heart attack and stroke during surgery, as well as post-surgery risks such as lung problems, irregular heartbeat and infection, the news release noted. Read more…
