Some people have a heart condition where the wall, called the septum, between the heart's main chambers is too thick. This problem can block blood flow, leading to serious symptoms like chest pain or shortness of breath. This study is testing a new way, called SESAME, to fix it by cutting away extra tissue from the septum.
Adults aged 21 and older with this condition are eligible to participate. Participants will need to stay in the hospital for 2 to 6 days for the procedure. During the procedure, they will be sedated, and doctors will use special tools to remove the excess tissue. After the procedure, there will be three follow-up visits within a year to check on recovery and results.
- Participants: Adults 21+ with specific heart conditions.
- Stay: 2 to 6 days in the hospital.
- Follow-up: 3 visits in 1 year.
