backward flow of blood that occurs when the aortic valve does not close tightly.
narrowing of the aortic valve’s opening when its cusps become stiff and rigid.
invasive, nonsurgical procedure to enlarge a narrowed heart valve using a deflated balloon that is threaded through a peripheral blood vessel into the stenotic valve, then inflated to stretch the opening.
area where the cusps of a cardiac valve con-tact each other.
backward flow of blood that occurs when the mitral valve does not close completely; some-times referred to as mitral insufficiency.
disorder in which the mitral valve does not open sufficiently to facilitate filling of the left ventricle.
disorder in which the mitral valve cusps enlarge, become floppy, and bulge backward into the left atrium.
cluster of symptoms as-sociated with autonomic nervous system dysfunction in which changes in mitral valve tissue layers cause its cusps to distend, stretching the papillary muscles and leading to valvular incompetence.
place on the chest wall where heart pulsations are most strongly felt.
minimally inva-sive technique for replacing a stenotic aortic valve with a balloon catheter, self-expanding stent, and prosthetic valve.
condition in which the aortic valve does not close tightly.
leaking of blood backward through a valve that does not close tightly.
assessment finding characterized as strong radial pulse with quick, sharp beats followed by a sudden collapse of force.
