Heart valves are like sluices in the heart that open and let the blood through. However, in the course of life the heart valves wear out. This can lead to calcium deposits. This narrowing prevents the blood from flowing through properly.
If medication does not help sufficiently, the heart valves must be replaced. Sometimes, however, older patients are plagued by several diseases, are weakened and cannot be operated on. Exactly for these patients there is a gentle method to replace the heart valves without opening the chest. "Health Today" takes a closer look and wants to know whether this newer technology delivers what it promises.
