Valley Valvular Lesions Flashcards
Mitral stenosis is usually due to?
Rheumatic Fever
Symptoms of mitral stenosis occur when the mitral valve orifice is less than how many cm^2?
2 cm^2
Acute elevations of left atrial pressure will cause pulmonary congestion if pulmonary capillary pressure rises above how many torr?
25 torr
Mitral stenosis will usually result in?
Embolic events and a-fib
Associated with mitral regurgitation is:
reduction in forward stroke volume
Mitral regurgitation has a regurg volume based on what factors?
- mitral valve size
- heart rate
- pressure gradient between the atria and ventricle
Mitral Regurg management involves what?
maintaining or slightly increasing the preload
Aortic stenosis is associated with what stroke volume change?
Maintained stroke volume because of ventricular concentric hypertrophy.
Aortic regurgitation causes:
Volume overload of the left ventricle.
Acute aortic regurgitation presents with a sudden onset of pulmonary edema and what?
hypotension
What is the most common cause of aortic stenosis?
rheumatic valvular disease
How should after load be managed in the hypertrophic cardiomyopathy patient?
increased
