1

Feline DCM

- Most common cause = Dietary taurine deficiency
- Spontaneous DCM = rare
- Breeds - siamese / Burmese/ Abyssinian
- Dx + Rx - similar to dogs
- Px - POOR - most present once in heart failure ; can survive if responsive to taurine and live through hospitalization

2

Feline Pericardial Effusion

uncommon in cats, unless manifestation of heart failure

3

Feline Heartworms

CS - ** vomiting** , intermittent cough, increased RR, sudden death

DDX - feline asthma, allergic bronchitis, other causes of vomiting

Test - Rads ( lung pattern )
- Antigen test ( false - due to either male only infection or immature female infection )
- Antibody test ( positive only means an infection occurred once before )
- Ultrasound ( may see worm in pulmonary artery )

Tx - DO NOT give Melarsomine
- Prednisolone ( to help with lung changes )

Px - Guarded ( sudden death) --> fair

4

Feline A-fib

Usually seen in cats with advanced cardiomyopathy

5

HCM/ thromboembolism ( presentation )

males > females
Maine coons and ragdolls
often no CS, no murmur, no arrhythmias, die actually

Cs- mild tachypnea, dyspnea, inability to use back legs, pulmonary edema, pleural effusion

* decompensated cats with CHF = hypothermic

6

HCM ddx:

lower airway dz
other non-cariogenic causes of pleural effusion (idiopathic chylothorax)
hyperthyroid

7

HCM tx

support oxygen

atenolol ( if LV outflow obstruction seen via ECHO )

CHF --> loop diuretics for life +/- pimobendaan

Clopidogrel ( if marked atrial enlargement +/or echo contrast in LA ) ---> prevents thromboembolism
