Endocarditis (Heart Lining/Valve Inflammation)

Image for the Heart & Circulation category

In endocarditis, usually bacteria colonise the heart lining and especially the heart valves, forming inflammatory deposits there, so-called vegetations. These damage the valves, produce a heart murmur and can wash small infectious fragments into the circulation; the disease is serious and often runs with persistent or recurrent fever.

Veterinary care required

This condition belongs in veterinary diagnosis and treatment. Compounds are at most supportive.

Priority · vet & management

Clarification belongs urgently with veterinary cardiology: echocardiography (detection of valve vegetations), auscultation, ECG as well as blood count, inflammation values and blood cultures to identify the pathogen. Treatment is by a longer, targeted antibiotic therapy strictly by the vet; complementary feeds have no role here and must in no way replace the antibiotic treatment.

Possible causes

  • · bacteraemia from other foci of infection (e.g. dental, respiratory, wound infections)
  • · pre-damaged heart valves as a target
  • · septic thrombophlebitis or infected venous accesses as an entry point
  • · weakened defences as a favouring factor

Supportive compounds · supplementary feed, not medication

Prevention

Consistently treating foci of infection (teeth, wounds, airways), careful hygiene with venous accesses and early work-up of unclear fever reduce the risk of bacteria colonising the heart valves.

Equiterna's take

Equiterna links endocarditis to the idea that unclear fever plus a new heart murmur should always make one think of the heart — diagnosis via echocardiography and blood cultures as well as the antibiotic therapy remain strictly veterinary.
