简要总结
Background:
TAVR is a common therapy for people with heart problems. It stands for transcatheter aortic valve replacement, TAVR can be a better option than surgery. But it isn t safe for everyone. It may block the arteries that supply blood to the heart muscle by pushing heart valve tissue outward. Researchers want to study a method that may make TAVR safer. It is known as Bioprosthetic or native Aortic Scallop Intentional Laceration to prevent Iatrogenic Coronary Artery obstruction (BASILICA).
Objective:
To study the feasibility and safety of BASILICA in people at high risk of coronary artery obstruction that complicates TAVR.
Eligibility:
People at least 21 years old whose heart doctors do not think they can have TAVR safely
Design:
Participants will be screened by a team of heart specialists. They will have heart and blood tests. They will answer questions.
Participants will have TAVR using BASILICA.
They will get general anesthesia or they will be sedated.
While using x-rays and echocardiography, doctors will cross and split the aortic valve leaflet using an electrified wire.
A standard TAVR valve will be implanted.
After the procedure, participants will have blood tests and physical exams. They will answer questions. They will have heart tests.
Participants will have a scan within 1 month and after 12 months. They will have heart tests during follow-up visits in the first year.

详细描述
Transcatheter aortic valve replacement (TAVR) is an option to treat aortic valve stenosis or failure of a surgically implanted tissue valve. Sometimes TAVR displaces the diseased aortic valve leaflets outwards, causing life-threatening obstruction of the coronary arteries that supply blood to the heart. This is more common in surgically implanted tissue valves that are designed to achieve the largest aortic valve orifice area. Despite attempts to protect the coronary arteries from obstruction in these patients using coronary stents, the mortality of TAVR-associated coronary artery obstruction remains prohibitively high.
The investigators have developed and tested a technique to tear the existing aortic valve leaflet and enable TAVR in such patients. The procedure is called Bioprosthetic or native Aortic Scallop Intentional Laceration to prevent Iatrogenic Coronary Artery obstruction (BASILICA).
The purpose of this study is to perform BASILICA in patients who have no good options to prevent coronary artery obstruction during TAVR.
