How CRT works for adults with congenital heart disease

This study follows adults born with a heart condition to see how they do over time, whether they had surgery or not. It aims to learn more about their health journey.

This study looks at how adults with congenital heart disease (a heart problem you were born with) do over time. By reviewing medical records, doctors hope to learn what affects long-term health and help improve care for patients like you.

This trial tests whether a special noninvasive heart “mapping” test done on the body can help improve outcomes for people who need a CRT device. It studies whether mapping before implantation can better guide or predict how well the CRT will work.

This study looks at whether a device called CRT (Cardiac Resynchronization Therapy) can help people with heart failure who have a weak heart pumping strength and a “wide” electrical signal pattern on an ECG. It may help some people feel better and improve heart function, especially if they are not already on the best standard medicines.

This trial evaluates a noninvasive way to assess who should get Cardiac Resynchronization Therapy (CRT), and to check results after implantation. If you fit the heart rhythm and heart pump criteria, the approach may help confirm whether CRT is appropriate for you.

This study tests a new heart scan method to help doctors improve pacemaker treatment for people with heart failure. If you already qualify for a special pacemaker called CRT, this scan may make the treatment work better for you.
