What is an Inferobasal aneurysm?
patient with myocardial infarction; inferobasal LV aneurysms. are usually visible in the parasternal long-axis and two-chamber. views appearing as a thinned and hyperechogenic bulged. portion of the myocardial wall.
What is a ventricular pseudoaneurysm?
Left ventricular pseudoaneurysms are false aneurysms that result from contained myocardial rupture, and are a rare complication of myocardial infarction (MI). They should not be confused with left ventricular aneurysms, which are true aneurysms containing all the layers (endocardium, myocardium, and epicardium).
What is Outpouching in the heart?
Aneurysm, cardiac: An outpouching of an abnormally thin portion of the heart wall. Cardiac aneurysms tend to involve the left ventricle because the blood there is under the greatest pressure.
What is a left ventricular aneurysm?
A left ventricular aneurysm forms when a section of the heart muscle in the left ventricle (the chamber of the heart that pumps blood to the body) stretches and become very thin. This often is caused by a heart attack and can leave portions of the heart muscle dead or damaged.
How does ventricular aneurysm occur?
More specifically, a ventricular aneurysm is a blood-filled bulge that occurs as a result of an area of weakened tissue in the heart wall. In most cases, ventricular aneurysms form as a result of damage from a previous heart attack, though they may also be caused by defects present from birth.
Can a ventricular aneurysm rupture?
Ventricular aneurysms usually develop slowly over time and are not prone to ruptures, so they can be effectively treated in many cases with monitoring, medication and lifestyle changes. Larger aneurysms that constrict blood flow out of the heart can lead to congestive heart failure and may require surgery.
What is a true ventricular aneurysm?
[4] Ventricular aneurysms can be true or false aneurysms. [5] A true aneurysm is formed by full-thickness bulging of the ventricular wall. In contrast, a false ventricular aneurysm is formed by the rupture of the ventricular wall, which is contained by the surrounding pericardium.
What is cardiac diverticulum?
Congenital cardiac diverticulum (CCD) is a very rare congenital malformation characterized by a muscular appendix emerging from the left ventricular apex, rarely from the right ventricle or from both chambers, with clinical manifestations ranging from asymptomatic to life-threatening hemodynamic collapse.
What is left ventricular diverticulum?
Cardiac diverticula are rare and typically arise from the left ventricle. Cardiac diverticula are outpouching structures that contain endocardium, myocardium, and pericardium and display normal contraction. 1. Earlier reports have identified a prevalence of 0.4%, or 3 in 750 cases, of cardiac necropsy cases.
