2. Batista procedure - Wikipedia

   en.wikipedia.org/wiki/Batista_procedure

   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 ...

3. Ventriculectomy - Wikipedia

   en.wikipedia.org/wiki/Ventriculectomy

   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]

4. Ventricular remodeling - Wikipedia

   en.wikipedia.org/wiki/Ventricular_remodeling

   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 .

5. Mitral valve replacement - Wikipedia

   en.wikipedia.org/wiki/Mitral_valve_replacement

   The mitral valve is a bileaflet valve sited between the left atrium and left ventricle, responsible for preventing blood flowing from the ventricle to the atrium when the heart contracts. It is elliptical, and its area varies from 5.0 to 11.4 cm 2 .

6. Heart valve repair - Wikipedia

   en.wikipedia.org/wiki/Heart_valve_repair

   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 ...

7. Diastolic function - Wikipedia

   en.wikipedia.org/wiki/Diastolic_function

   To better understand diastolic function, it is crucial to realize that the left ventricle is a mechanical suction pump at, and for a little while after, the mitral valve opening. [5] In other words, when mitral valve opens, the atrium does not push blood into the ventricle, instead, it is the ventricle that mechanically "sucks" in blood from ...

8. Coronary artery bypass surgery - Wikipedia

   en.wikipedia.org/wiki/Coronary_artery_bypass_surgery

   The beneficial effects of CABG are clear at the cardiac level. Left-ventricle function is improved and malfunctioning segments of the heart—dyskinetic (moving inefficiently) or even akinetic (not moving)—can show signs of improvement. Both systolic and diastolic functions are improved and keep improving for up to five years in some cases. [37]

9. Mitral stenosis - Wikipedia

   en.wikipedia.org/wiki/Mitral_stenosis

   When the mitral valve area goes less than 1 cm 2, there will be an increase in the left atrial pressures (required to push blood through the stenotic valve). Since the normal left ventricular diastolic pressures is about 5 mmHg, a pressure gradient across the mitral valve of 20 mmHg due to severe mitral stenosis will cause a left atrial ...
