mitral regurgitation

MR is the most common form of:

valvular heart disease

in rheumatic fever, the valves most affected in order are the:

• mitral

• aortic

• tricuspid

• pulmonary

MVP should not be diagnosed in the presence of:

a large pericardial effusion

anterolateral papillary muscle

gets a double blood supply from the left anterior descending (LAD) an left circumflex arteries

posteromedial papillary muscle

has a single blood supply from the RCA and is more likely to become ischemic

what is the most common cause of papillary muscle dysfunction?

scarring of the papillary muscle from CAD or after myocardial infarction (MI)

in bacterial endocarditis, the smallest vegetation visible on echo measures:

2 mm

systolic anterior motion (SAM) of the MV

when the entire closed MV moves anteriorly in systole

normal flow velocities through the MV should not exceed:

1.3 m/s

what type of imaging mode has become the method of choice to assess the degree of MR?

color doppler

mild MR color jet area measurement:

< 20%

severe MR color jet area measurement:

> 40%
