Secondary right atrial thrombosis in three dogs: Antithrombotics therapy and echocardiographic follow‐up

Figures

  FIGURE 1. Echocardiographic images taken before (a, b) and after (c, d) the antithrombotic therapy in Case 1 diagnosed with hyperadrenocorticism and pancreatitis. a: Right parasternal long‐axis view before antithrombotic therapy, showing a thrombus (indicated by the yellow arrow) occupying the right atrium. b: Right parasternal long‐axis view with colour Doppler imaging before antithrombotic therapy, demonstrating the thrombus obstructing the blood flow. c: Right parasternal long‐axis view after antithrombotic therapy on Day 40, illustrating partial resolution of the thrombus after treatment indicated by the yellow arrowhead . d: Right parasternal long‐axis view after antithrombotic therapy on Day 68, which the thrombus in the right atrium had disappeared shown by the yellow arrowhead. RA: right atrium, RV: right ventricle, LA: left atrium, LV: left ventricle.

  FIGURE 2. Echocardiographic and abdominal ultrasound images before (a, b) and after (c, d) antithrombotic therapy in Case 2 diagnosed with acute kidney injury and pancreatitis. a: Left parasternal apical four‐chamber view before antithrombotic therapy. b: Two‐dimensional longitudinal ultrasound with colour Doppler imaging of the aorta before antithrombotic therapy. Yellow arrows indicate a hyperechoic mass representing a thrombus within (a) the right atrium a and (b) aortic lumen. c: Left parasternal apical four‐chamber view after antithrombotic therapy. d: Two‐dimensional longitudinal ultrasound with colour Doppler imaging of the aorta after antithrombotic therapy. The thrombus in the right atrium and aortic lumen had disappeared indicated by the yellow arrowheads. RA: right atrium, RV: right ventricle, LV: left ventricle.

  FIGURE 3. Echocardiographic images taken at left parasternal apical four‐chamber view in Case 3 with diagnosed with hyperadrenocorticism and pancreatitis on Day 1 (a), Day 14 (b), and Day 93 (c). Yellow arrowheads indicate the hyperechoic mass representing a thrombus within the right atrium. Gradual disappearance of the thrombus can be observed. The scan lines were narrowed down to increase the resolution of the image in c.
