Mitral Valve

The heart's mitral valve is the site of the most surgical valve repairs and valve replacements. After the resounding success of transcatheter aortic valve replacement (TAVR), which now makes up more than 50% of aortic valve replacements, there is wide expectation transcatheter mitral replacements will follow in the next few year. Currently, the most common transcatheter mitral procedure is transcatheter edge-to-edge (TEER) , using the MitraClip or Pascal clip devices. These devices are also being used for transcatheter tricuspid valve repair (TTVR). Other transcatheter mitral repair systems are in trials for minimally invasive annuloplasty and chordae tendineae repair.

X-ray photon trajectory during the simulation phantom study from the side and top views. Due to scattering of the X-rays when they hit the lower end of the patient bed, exposure in mainly to the lower body of the interventional echocardiographer performing transesophageal echocardiography. The green lines are the scattered photon trajectories calculated by Monte Carlo simulation in the study.
