MitraClip، a small device inserted into the body، can work miracles to patients suffering from severe heart failures، a recent clinical trial has revealed، as the Technical Times said. Researchers said that patients who used the clip reported fewer symptoms and a significantly improved quality of life. The results were revealed during a medical meeting in San Diego. The clinical trial was also documented in the New England Journal of Medicine. The large clinical trial involved patients from 78 sites across the United States and Canada. Researchers divided volunteers into two groups: one group received transcatheter mitral-valve repair plus medical therapy (device group) while the other group assigned medical therapy alone (control group). All participants were diagnosed with moderate to severe heart failures and do not respond to regular treatment. Researchers report that out of 614 patients، 151 patients from the control group were hospitalized for heart failure after two years. A total of 61 people died within the trial period. Meanwhile، only 92 people from the group assigned to use MitraClip were hospitalized while only 28 died. "It's a huge advance،" stated Dr. Howard Hermann، director of interventional cardiology at the University of Pennsylvania. "It shows we can treat and improve the outcomes of a disease in a way we never thought we could."
