Cardiac Valves

After the first transcatheter aortic valve replacement became a reality in humans in 2002, there has been an explosion in the development of transcatheter devices for the treatment of various heart valve diseases. A variety of different design concepts have collided with each other, and various devices are increasingly being used in clinical care. Specifically, transcatheter treatment of aortic stenosis with transcatheter aortic valve replacement as the primary approach is relatively mature and has gained more clinical evidence, and although this technique still has more complications, corresponding ideas for improvement have been generated. Other valvular diseases with a higher incidence, such as aortic regurgitation, mitral regurgitation, pulmonary stenosis, and tricuspid regurgitation, are still in the process of continuous experimentation. In this chapter, we provide an overview of transcatheter devices for the abovementioned high-incidence heart valve diseases.
