Left Ventricular Aneurysm is a balloon-shaped sac in a part of the left ventricular muscle, which is the lower left chamber of the heart. The sac-like heart muscle cannot contract and cannot contribute to the pumping function of the heart. In addition, clots can form here and rhythm disorders can be seen in the heart. Left ventricular aneurysm repairs are performed with different surgical techniques, depending on the size and characteristics of the aneurysm.
