Left ventricular thrombus is a blood clot in the left ventricle of the heart. LVT is a common complication of acute myocardial infarction (AMI). [ 1 ] [ 2 ] Typically the clot is a mural thrombus, meaning it is on the wall of the ventricle. [ 3 ]
Ischemic cardiomyopathy is a type of cardiomyopathy caused by a narrowing of the coronary arteries which supply blood to the heart. [4] Typically, patients with ischemic cardiomyopathy have a history of acute myocardial infarction, [5] however, it may occur in patients with coronary artery disease, but without a past history of acute myocardial infarction.
It helps form the posterior left ventricular branch or posterolateral artery. The circumflex artery ends at the point where it joins to form to the posterior interventricular artery in 15% of all cases, which lies in the posterior interventricular sulcus .
Left ventricular mass or LVM refers to the mass of the left ventricle of the heart. Left ventricular mass index or LVMi is LVM divided by body surface area . LVM is usually estimated using linear measurements obtained from echocardiography , [ 1 ] but can also be calculated using CT or MRI images. [ 2 ]
A thrombus (pl. thrombi), colloquially called a blood clot, is the final product of the blood coagulation step in hemostasis. There are two components to a thrombus: aggregated platelets and red blood cells that form a plug, and a mesh of cross-linked fibrin protein. The substance making up a thrombus is sometimes called cruor.
Also, blood clots may form on the inside of ventricular aneurysms, and form embolisms. If such a clot escapes from the aneurysm, it will be moved in the circulation throughout the body. If it gets stuck inside a blood vessel, it may cause ischemia in a limb, a painful condition that can lead to reduced movement and tissue death in the limb. [1]
[5] [6] A more technical definition is from the proximal segment to the point where the LAD forms an angle, as seen from a right anterior oblique view on angiography, which is often close to the origin of the second diagonal branch. [7] Distal: from middle segment to apex, [5] [6] or in some cases beyond. [7]
The type of VAD implanted depends on the type of underlying heart disease (e.g. patients with right ventricular failure from pulmonary arterial hypertension may require an RVAD, versus those with left ventricular failure from a myocardial infarction may require an LVAD). The LVAD is the most common device applied to a defective heart (it is ...
