Core official overview

What this condition is

What are heart valve diseases?Heart valve disease happens when one or more of your heart valves don't work well.Your heart has four valves: the tricuspid, pulmonary, mitral, and aortic valves. The valves have flaps that open and close. The flaps make sure that blood flows in the right direction through your heart and to the rest of your body. When your heart beats, the flaps open to let blood through. Between heartb…

One Year Pacing Dependency After TAVR

NCT06756282

Pace maker implantation after the procedure of TAVR can be estimated at 15% of patients. However, some studies have shown that the conduction disturbances after TAVR could resolve over time, and that roughly between one- and two-thirds of…

"Congenital" means that that the problems are present at birth. These defects happen when a fetus's heart doesn't develop normally during pregnancy. Congenital heart defects are the most common type of birth defect.Congenital heart defects can change the way the heart pumps blood. They may make blood flow…
