What causes LV thrombus?

What causes LV thrombus?

Left ventricular (LV) thrombus may develop after acute myocardial infarction (MI) and occurs most often with a large, anterior ST-elevation MI (STEMI). However, the use of reperfusion therapies, including percutaneous coronary intervention and fibrinolysis, has significantly reduced the risk.

How is LV thrombus treated?

Intravenous thrombolysis has also been used for treatment of documented LV thrombus. In a report of 16 patients with LV thrombus on echocardiography, urokinase was infused intravenously at a rate of 60 000 U/h for 2–8 days in combination with intravenous heparin (200 units/kg×12 h).

What is LV apical thrombus?

Left ventricular thrombus is a blood clot (thrombus) in the left ventricle of the heart. LVT is a common complication of acute myocardial infarction (AMI). Typically the clot is a mural thrombus, meaning it is on the wall of the ventricle.

What is the difference between blood clot and thrombosis?

A thrombus is a blood clot that occurs in and occludes a vein while a blood clot forms within an artery or vein and it can break off and travel to the heart or lungs, causing a medical emergency.

What are the types of thrombus?

There are 2 main types of thrombosis:

• Venous thrombosis is when the blood clot blocks a vein. Veins carry blood from the body back into the heart.
• Arterial thrombosis is when the blood clot blocks an artery. Arteries carry oxygen-rich blood away from the heart to the body.

What is organization of thrombus?

THE expression ” organisation ” of a thrombus is widely and loosely. used to describe the changes which in the course of time convert it. into living tissue. The same expression is used for changes of a. similar type which occur in pericardial or pleural fibrinous exudates.

Can DOAC be used for LV thrombus?

Hence, DOACs can be considered in patients with LV thrombus. However, large randomized studies comparing the effectiveness of DOACs to warfarin in LVT patients are needed to confirm these findings.

What is left atrial thrombus?

The left atrial thrombus is a well-known complication of atrial fibrillation and rheumatic mitral valve disease and carries a high risk for systemic thromboembolism. They are generally dissolved after a certain period of optimal anticoagulation.

What is the clinical significance of left ventricular thrombus (LVT)?

Left ventricular thrombus (LVT) is a frequent complication in patients with acute anterior myocardial infarction (MI) and in those with dilated cardiomyopathy (DCM). The clinical importance of LVT lies in its potential to embolize.

What is the relationship between lvidd and LV thrombosis?

Patients with LV thrombi had larger LV chamber sizes with LVIDD measurements than patients without LV thrombus (74.0 ± 7.7 mm vs 66.4 ± 9.9 mm; p = 0.0005) in addition to more frequently anteroapical aneurysms (14.3% vs 3.5%; p = 0.05) and a demonstrated trend toward lower EF (17.5 ± 5.5% vs 20.0 ± 6.9%; p = 0.07), respectively.

What is the role of non-contrast echocardiography in the workup of LV thrombosis?

Non-contrast echocardiography (echo) detects LV thrombus based on anatomical appearance. This approach can be straightforward when thrombus is large in size and protuberant in shape, but challenging when thrombus is small or mural. While thrombi can vary in size and shape, it can be intrinsically defined based on avascular tissue composition.

What is thrombus blood clot?

THROMBUS BLOOD CLOT 1- Involves wall of blood vessels, formed elements of blood & blood clotting system. 1- Involves only blood clotting system. 2- composed of platelets and fibrin. 2- composed of fibrin only. 3- may be life-threatening. 3- mostly life saving. 2. THROMBUS – GROSS PATHOLOGY 3. THROMBUS – MICROSCOPIC PATHOLOGY 4.
