Some bad heart valve operations may soon become a thing of the past. New studies show that it is good and often better if the new valve is placed through the tube into the artery. Don't let the blood pass as it should. Until now, the detection of serious cases required a major operation using the pulmonary machine, and the surgeons pulled out the old valve and sewed into a new one. catheter into the blood vessel and insert into the old valve. But now they are only used for people who have a high or medium risk of dying from surgery. New studies have tested these valves for people with a low risk of surgery, as most patients have, and have found they are good or superior to surgery.
said dr. Joseph Cleveland, a heart surgeon at Colorado University, has no role in research or communication with their supporters. "It's a great thing for patients to avoid big surgery," he said.
The results were published by the New England Journal of Medicine on Saturday and should be discussed at the American College of Cardiology conference in New Orleans. Sunday
In one study, approximately 1
. Based on partial results, researchers estimate that after two years, 6.7 percent of deaths were reported. Surgical groups and 5.3 percent. Other patients
. heartbeat called atrial fibrillation. In the Medtronic study, 17% The recipients of expandable valves later demanded a pacemaker compared to 6 percent. Operations performed by persons.
Previous studies show that the cost of expandable valves costing about $ 30,000 is lower compared to $ 5,000 in surgery. since they require much shorter hospitals and less complications, Cleveland, who is also a member of the Cardiology College, said.
In the United States, aortic valve replacement surgery is decreasing. It is expected that only about 25,000 people will be made this year, and Cleveland expects that in 2021, 20,000 people will be taken. It will drop in half a year and again in half
. as surgical. Catheter-based methods related to the problems of some other heart valves, such as the Mitral valve, have also been developed or tested
