Valvular Disease Flashcards
order of valve progression in heart
tricuspid –> pulmonic –> mitral –> aortic
when do the tricuspid and aortic valves open?
during systole
when do the tricuspid and aortic valves close?
during diastole
where do valve abnormalities usually occur?
on left side of heart
valves with stenosis
very tight and stiff; hard for the blood to get through
what valve often experienced stenosis?
aortic
valves with regurgitation
very loose and floppy; blood flows backward with increased pressures
what valve often experiences regurgitation?
mitral
symptoms of aortic stenosis
–syncope
–light headedness
–chest pain
often asymptomatic
symptoms of mitral regurg
–fatigue
–shortness of breath
no chest pain
where does infective endocarditis usually occur? Why?
tricuspid valve; that is the first valve that comes into contact with infected blood from the bloodstream
what can happen if vegetation breaks loose from the tricuspid valve?
pulmonary embolus
what can happen if vegetation breaks loose from mitral valve?
systemic manifestations; clots/septic emboli
risk factors for infective endocarditis
–prosthetic valve
–pacemaker-associated
–IVDA
symptoms in infective endocarditis
–fever
–chills
–anorexia
–weight loss
–myalgias
–arthralgias
–heart murmur
