Chapter 19 - Part 13 - Non-rheumatic Aortic Stenosis and Mitral Valve prolapse

Essentials of Pathophysiology by Carol Porth - 3rd edition
STUDY
PLAY
Non-rheumatic aortic stenosis
-Occurs in 2% of population
-Congenital malformation of aortic valve
-Cardiac aortic stenosis
Non-rheumatic aortic stenosis
Occurs in 2% of population
Non-rheumatic aortic stenosis
Congenital malformation of aortic valve
-There is a bicuspid valve rather than the normal tricuspid valve
-Leads to valve thickening and scarring
Non-rheumatic aortic stenosis
Cardiac aortic stenosis
-Degenerative in the elderly
-Valve becomes very rigid which affects ability to open
2% of population
Non-rheumatic aortic stenosis: Occurs in _________________
Congenital malformation of aortic valve, bicuspid valve, tricuspid valve, valve thickening and scarring
Non-rheumatic aortic stenosis: _______________________
-There is a __________ rather than the normal __________
-Leads to ___________________
Calcific aortic stenosis, becomes very rigid
Non-rheumatic aortic stenosis : __________________
-Degenerative in the elderly
-Valve __________________ which affects ability to open

Mitral valve prolapse
-A common condition but only a few develop problems
-One or both mitral leaflets are enlarged and redundant due
to degeneration of connective tissue
-Prolapse into left atrium, during ventricular systole - causes murmur
+Stress may rupture chordae
+Predisposes to arrhythmias
-Most are asymptomatic
Mitral valve prolapse
A common condition but only a few develop problems
Mitral Valve prolapse
One or both mitral leaflets are enlarged and redundant due to generation of connective tissue
Mitral valve prolapse
Prolapse into left atrium, during ventricular systole - causes murmur
-Stress may rupture chordae
-Predisposes to arrhythmias
Diagnosis of Mitral valve prolapse
Echocardiography
Mitral valve prolapse
Most are asymptomatic
Prolapse into left atrium, ventricular systole, murmur
Mitral valve prolapse: ______________, during __________________ - causes _________
common condition, a few develop problems
Mitral valve prolapse: A _____________but only __________________
asymptomatic
Mitral valve prolapse: Most are ________________
Prolapse into left atrium, may rupture chordae,
arrhythmias
Mitral valve prolapse: ______________, during ventricular systole - causes murmur
-Stress ____________
-Predisposes to ___________
Mitral Valve prolapse:
One or both mitral leaflets are enlarged and redundant due
to degeneration of connective tissue
enlarged and redundant, degeneration of connective tissue
Mitral Valve prolapse: One or both mitral leaflets are __________ due to _________
Mitral valve prolapse with regurgitation
Needs prophylactic antibiotics prior to dental or surgical procedures
prophylactic antibiotics
Mitral valve prolapse with regurgitation: Needs __________ prior to dental or surgical procedures
leaky (regurgitant) prolapsing valves, an infection of the lining of the heart or heart valve
Those with______________ are at increased risk of developing ___________________
