case_images: Radiographs during one of the episodes of tachypnoea and dyspnoea in (a,b) case 1 and
  (c,d) case 2. (a,c) Dorsoventral and (b,d) right lateral radiographs show pulmonary
  oedema consistent with congestive heart failure

case_images: The cat developed the first respiratory episode at 8 months of age and was diagnosed via radiographs with CHF (Figure 1).
case_images: Still images taken at end-diastole from the echocardiographic evaluation of (a-c)
  case 1 and (d-f) case 2: (a,d) four-chamber right-sided parasternal long-axis view;
  (b,e) right-sided parasternal short-axis view at the level of the papillary muscles;
  and (c,f) right-sided short-axis view at the level of the left atrium and aorta

case_images: An echocardiogram showed an HCM phenotype with normal LA size (Figure 2; see Table S1 in the supplementary material).

case_images: Two weeks later, the cat had a short-lasting tachypnoea and paroxysmal SVT episode (Figure 3).

case_images: The cat re-presented with an HR of 320 bpm and recurrent SVT (Figure 4), tachypnoea, signs of cardiogenic shock (subdued mentation, pale-pink mucous membranes and absent femoral pulses with cold extremities) and severely matted fur covering approximately 80% of the abdomen.
