Just came back from routine, yearly exam & shots. The (new) Vet had
bad news...in BOTH my kitties (M 6yr old & F 12yr old) he detected
possible heart murmurs. He (the Vet) didn't give me much info...
Here are a few link that give helpfull information;
Murmurs are blowing, whooshing, or rasping sounds.
They are the result of vibrations caused by abnormal
blood flow patterns. This can happen when a valve
does not close tightly (such as with mitral
regurgitation), when there is an irregularity in the shape
of a heart chamber or one of the great vessels (such as
an aortic aneurysm), or when the blood is flowing
through a narrowed opening or a stiff valve (such as
with aortic stenosis).
A murmur does not necessarily indicate a disease or
disorder, and all heart disorders do not cause murmurs.
Murmurs are classified,("graded") depending on their
ability to be heard by the examiner. The grading is on a
scale with grade I being barely detectable. An example
of a murmur description is a grade II/VI murmur (grade 2
on a murmur scale of 1 to 6).
Also used to describe a murmur is the stage of the
heartbeat when the murmur is heard. Whether the
murmur occurs in the resting stage (diastole) or
contracting stage (systole), whether it is early or late
in the stage, or whether it occurs throughout the
heartbeat, are important clues to the cause of the
murmur. For example, a presystolic murmur is heard just
BEFORE systole and is usually caused by narrowing of
the mitral or tricuspid valve (the valves between the
atria and the ventricles).
Common causes Murmurs:
mitral regurgitation; chronic
mitral regurgitation; acute
Innocent Heart Murmurs
I hope this helps,
