Devices and methods are disclosed for the treatment or repair of regurgitant cardiac valves, such as a mitral valve. An annuloplasty device can be placed in the coronary sinus to reshape the mitral valve and reduce mitral valve regurgitation. A protective device can be placed between the annuloplasty device and an underlying coronary artery to inhibit compression of the underlying coronary artery by the annuloplasty device in the coronary sinus. In addition, the protective device can inhibit compression of the coronary artery from inside the heart, such as from a prosthetic mitral valve that exerts radially outward pressure toward the coronary artery. The annuloplasty device can also create an artificial inner ridge or retaining feature projecting into the native mitral valve region to help secure a prosthetic mitral valve.
A protection device for protecting a coronary artery of a heart from being compressed between a prosthetic mitral valve secured within the mitral valve region of the heart and a mitral annuloplasty tension element extending at least partially through a coronary sinus of the heart over the coronary artery, the protection device comprising:
A method comprising:
The system of claim, wherein the annuloplasty tensioning element is configured to create a retaining feature projecting inwardly into the native mitral valve region when extending at least partially through the coronary sinus and placed under tension, wherein the transcatheter prosthetic mitral valve is configured to be secured to the retaining feature by applying radially outward expansion force on the retaining feature, and the protection member is configured to protect the coronary artery from compression by pressure applied by the expansion force of the prosthetic mitral valve.
