• RF
• Lateral
• Elevation of the trachea.
• Heart is taller than it should be.
• Marked loss of the caudal cardiac waist with soft
  tissue structure overlying the caudal heart base
  region.
• Upward deviation toward the heart of the caudal
  vena cava.
• Increased cardiophrenic contact.
• Prominent pulmonary vessels.
• DV
• Large soft tissue opacity of the hilar region,
  between the mainstem bronchi, which can be
  followed over to the 3 oclock position (left
  atrium and auricle).

• R/O
• Mitral insufficiency and secondary heart
  enlargement

• Next Cardiac ultrasound

5
10 year old M German Shepherd Civa

• Hx Dog is bradycardic and premature ventricular
  contractions were noted on ECG

10 year old M German Shepherd Civa

• RF
• Mild generalized cardiac enlargement.
• Incidental finding of spondylosis at several
  sites in the thoracic spine.
• R/O
• Dilatative cardiomyopathy
• Pericardial effusion
• Next ECG

8
10 year old cocker spaniel MN Sprocket

• Hx Presented for evaluation of a chronic cough.
  No signs of systemic illness and no heart murmur
  is ausculted. The patient has been treated with
  Furosemide (Lasix), Enalapril (cardiac drug) and
  Hycodan (cough suppressent)

10 year old cocker spaniel MN Sprocket

• RF
• Right ventricular enlargement.
• Trachea is mildly elevated so right atrial
  enlargement may also be present.
• Diffuse mild interstitial lung pattern consistent
  with normal age change.
• Liver is mildly enlarged.
• R/O
• Right sided cardiac enlargement
• Cor pulmonale
• Aquired right-sided cardiac enlargement
  (relatively uncommon)
• Bronchitis

11
6 year old FS Bernese Mountain Dog

• Hx Presented for surgical repair of a cranial
  cruciate ligament rupture. While under general
  anesthesia occasional ventricular pre-mature
  contractions were noted.

13
6 year old FS Bernese Mountain Dog

• RF
• Microcardia and small size of the pulmonary
  vessels.
• Lung fields are over-exposed making evaluation
  more difficult
• RD
• hypovolemia
• R/O
• Dehydration
• Shock
• Addisons disease (hypoadrenocorticism)
• Next ACTH stimulation test

14
4 year old German Shorthair Pointer Autumn

• Hx Has had 2 episodes of mild weakness/collapse
  associated with intense exercise. A persistent
  cough is also reported. A systolic murmur with
  the point of maximal intensity at the aortic
  valve was noted 1 year ago.

16
4 year old German Shorthair Pointer Autumn

• RD
• Mild right-sided cardiac enlargement
• Moderate diffuse interstitial lung pattern with
  bronchial markings (not prominent enough to call
  a broncho-interstitial lung pattern)
• R/O
• Tricuspid valve insufficiency
• Cor pulmonale (increased size of the right heart
  due to pulmonary hypertension)
• Presence of interstitial pattern is non-specific
  and R/O include lungworm infestation,
  interstitial pneumonia and interstitial changes
  due to prior pulmonary disease
• Next
• Echocardiography
• Baermann fecal exam

17
12 year old DSH Tuffy

• Hx Presented for mild ataxia. The owners report
  the cat seems to be breathing rapidly.
  Auscultation of the thorax was unrewarding.

12 year old DSH Tuffy

• RF
• Increased sternal contact of the heart and the
  aorta has a prominent appearance.
• Cardiac silhouette is wider than normal.
• Cranial border is slightly square on the lateral
  view.
• Heart has a Valentine shape.
• The cranial pulmonary vessels are seen and at the
  upper limits of normal size.
• RD
• Hypertrophic cardiomyopathy
• Next
• Echocardiogram

20
6-year old MN DSHFatty Lumpkin

• Hx Presented for evaluation of lethargy and
  increased respiratory rate

22
6-year old MN DSHFatty Lumpkin

• RF
• Cardiac silhouette is partially obscured by
  increased opacity within the thoracic cavity.
• The atrial region of the heart appears wide.
• The trachea is elevated.
• Mild pulmonary vascular congestion is present as
  well as free pleural fluid.
• RD
• Hypertrophic cardiomyopathy
• Congestive heart failure

23
9-year old MN SchipperkeRobbie

• Hx Presented for evaluation of a cardiac murmur.
  The murmur was not present the previous year. It
  is described as a grade 2-3 of 6 systolic murmur.

25
9-year old MN SchipperkeRobbie

• RF
• Caudal mainstem bronchi are elevated and there is
  loss of the caudal cardiac waste.
• In VD the left atrium is visible as a large round
  structure caudal to the mainstem bronchi
  bifurcation.
• The entire trachea is elevated and the caudal
  cardiac margin is elongated.
• In the VD there is mild bulging in the left
  ventricular region.
• RD
• Left atrial and ventricular enlargement
• R/O
• Mitral regurgitation secondary to mitral valve
  endocardiosis

26
12 year old M SalukiLinca

• Hx Presented with a 1 week history of lethargy
  and poor appetite. On PE the abdomen appears
  distended and a fluid wave can be balloted. On
  auscultation the heart sounds are muffled and of
  variable intensity.
