Aortic stenosis is a heart valve disorder in which the aortic semi-lunar valve opening is narrow.
Which effect could aortic stenosis have on the heart structure and function?
1 )
The tendons of the heart valves are weakened by blood being forced back through the bicuspid/left atrio-ventricular valve into the left atrium.
2 )
The cardiac muscle of the left ventricle wall is thinned by blood leaking out of the left ventricle during ventricular diastole.
3 )
There is less cardiac muscle in the left ventricle and reduced diastolic blood pressure, caused by the smaller blood volume entering the left atrium.
The wall of the left ventricle thickens, leading to an enlarged heart and inability to relax and fill completely during diastole.
