In older dogs with heart murmurs, degenerative mitral valve disease is also the most common cause of a new heart murmur at this age. The mitral valve thickens, making it difficult to close during a heartbeat, resulting in a leak.

What structural heart problems cause a heart murmur?
The heart is composed of four chambers - the left atrium, the left ventricle, the right atrium, and the right ventricle. Blood flows from the right side of the heart through the pulmonary artery to the lungs where it is oxygenated, and then the oxygenated blood goes through the left side of the heart and into the aorta, where it is pumped to the rest of the body. Between each of the chambers and main blood vessels there is a valve that functions to prevent blood flowing back into the chamber as the heart pumps.

no such thing as 'stage 5' heart failure.. what you said initially was she had a 5/6 heart murmur... but that is NOT a symptom of stage 3 or worse heart failure... just that there is something wrong with her heart valves. Does NOT mean she needs any treatment whatsoever, UNLESS a cardiologist deems it necessary sans any outward symptoms (sometimes there are discoveries during an echo that lead cardiologists to initiate therapy early). Heart murmurs are rated on a scale of 1-6, with 1 being barely audible with a stethoscope (NOT audible by me usually), and 6 being such a loud heart murmur one can practically hear it without a stethoscope.

A low resting bpm (heart beats per minute) is considered healthy as it is an indication that the heart is strong and can adequately push blood through the network of arteries and veins without excessive resistance. A high resting bpm suggests that the heart is weak or there are other underlying conditions reducing an effective cardiac cycle. When an abnormality is present in the flow of blood, it makes a sound which is referred to as a murmur. This is distinctly different from the normal rhythm of the heart that you’ll hear through a stethoscope.
