What is left ventricular Akinesis?
The advent of cineventriculography has made it clear that there is a spectrum of motion disturbances involving the left ventricular wall. Akinesis, or lack of wall motion, is one serious complication of myocardial infarction that may have a profound effect on cardiac hemodynamics.
What is the left ventricular apex?
The left ventricular apex is located at the bottom of the left ventricle inferior to both the mitral and aortic valve. It is close to but separated from the right ventricular apex by the interventricular septal wall.
What is ventricular dyskinesia?
Ventricular dyskinesia denotes a segment of the ventricle wall that exhibits a paradoxical, outward movement during systole causing intraventricular “shunting” of blood flow between systole and diastole.
What is Dyskinesis of the heart?
In contrast to akinesia, dyskinesia is characterised by outward movement of a wall segment during systole. Defined in this way dyskinesia includes aneurysm formation; aneurysms, however, show bulging during diastole as well, and a thinner myocardium.
What is mild LV systolic dysfunction?
LV systolic dysfunction was defined as an ejection fraction (EF) of less than 40% by echocardiography. The recovery of LV systolic function was defined as recovery of the EF to a level of 40% or greater and a net increase in EF of 10% or greater.
Is the left ventricle the apex of the heart?
The apex (the most inferior, anterior, and lateral part as the heart lies in situ) is located on the midclavicular line, in the fifth intercostal space. It is formed by the left ventricle.
What is dyskinetic septum?
Septal dyskinesia was defined as either paradoxical septal motion or stretching of the segmental wall during systole. Six patients with septal dyskinesia and LV dysfunction underwent more sophisticated echocardiographic examinations both before and after RFA.
