MitraClip (mitral clip) is a medical device used to treat mitral valve regurgitation for individuals who should not have open-heart surgery. It is implanted via a tri-axial transcatheter technique and involves suturing together the anterior and posterior mitral valve leaflets.
Mitral regurgitation (MR), also known as mitral insufficiency or mitral incompetence, is a form of valvular heart disease in which the mitral valve is insufficient and does not close properly when the heart pumps out blood.
The mitral valve may need to be replaced because: [citation needed] The valve is leaky (mitral valve regurgitation) The valve is narrowed and doesn't open properly (mitral valve stenosis) Causes of mitral valve disease include infection, calcification and inherited collagen disease. Current mitral valve replacement approaches include open heart ...
The device fastens together the mitral valve leaflets to improve the heart's blood outflow. The mitral clip has not yet established the same long-term reliability as septal myectomy or alcohol septal ablation, but HCM specialists are increasingly offering the clip as a less-invasive treatment option. [60] [61]
Cardiac magnetic resonance imaging (cardiac MRI, CMR), also known as cardiovascular MRI, is a magnetic resonance imaging (MRI) technology used for non-invasive assessment of the function and structure of the cardiovascular system. [2]
Mitral valve repair is a cardiac surgery procedure performed by cardiac surgeons to treat stenosis (narrowing) or regurgitation (leakage) of the mitral valve. The mitral valve is the "inflow valve" for the left side of the heart. Blood flows from the lungs, where it picks up oxygen, through the pulmonary veins, to the left atrium of the heart.
The Mustard procedure improved an 80% mortality rate in the first year of life to an 80% survival at age 20. Long-term follow-up studies now extend to more than 40 years post-operation [ 4 ] and there are numerous patients thriving in their 50s.
This test can also show leaflet calcification and the pressure gradient over the mitral valve. [32] Severe mitral stenosis is defined as a mitral valve area <1.5 cm 2. [8] Progressive mitral stenosis has a normal valve area but will have increased flow velocity across the mitral valve. [8]
