The Batista procedure (also called a reduction left ventriculoplasty) was an experimental heart procedure that proposed the reversal of the effects of remodeling in cases of end-stage dilated cardiomyopathy refractory to conventional medical therapy. The hypothesis of the operation appears to be that reduction (resection) of marginally viable ...
Mitral valve repair is mainly used to treat stenosis (narrowing) or regurgitation (leakage) of the mitral valve. [citation needed] A mitral balloon valvuloplasty enlarges the valve opening to allow greater oxygenated blood flow into the left ventricle, and since severe mitral regurgitation can be a major complication, degrees of stenosis, regurgitation, and valve anatomical features are taken ...
Because the Dor procedure restores the left ventricle to its correct, elliptical orientation, it results in a mean ejection fraction increase of 12.5%. This number continues to improve over the patient’s lifetime, and patients can expect to live an extra 4–10 years, which is 3.3% longer than CABG alone with virtually no extra risk.
Ventriculectomy, or ventricular reduction, is a type of operation in cardiac surgery to reduce enlargement of the heart from cardiomyopathy or ischemic aneurysm formation. In these procedures, part of the ventricular wall is resected. [1] A Batista procedure is a partial left ventriculectomy that is used to treat advanced heart failure. [1]
Ventricular remodeling may include ventricular hypertrophy, ventricular dilation, cardiomegaly, and other changes. It is an aspect of cardiomyopathy , of which there are many types. Concentric hypertrophy is due to pressure overload , while eccentric hypertrophy is due to volume overload .
Bypass surgery is performed by removing a vein from the arm or leg, or an artery from the chest and replacing the blocked artery in the heart. This allows the blood to flow more freely through the heart. Valve repair is where the valve that is causing heart failure is modified by removing excess valve tissues that cause them to close too tightly.
This vortex rotates clockwise until the isovolumetric contraction of the left ventricle opens the aortic valve and redirects the fluid flow from the apex of the left ventricle to the systemic circulation and the rest of the body. [citation needed] The asymmetry of the mitral valve is very important in the diastolic flow patterns of transmitral ...
Mitral regurgitation is the most common form of mitral valve dysfunction. Today more than 2.5 million Americans are estimated to be affected by mitral regurgitation. This number is expected to double by the year 2030. Every year, 300,000 people worldwide undergo open heart surgery for mitral valve repair, 44,000 people in the US alone. [1]
