Abstract
A 10-year-old golden retriever was presented for the evaluation of exercise intolerance. Physical examination and laboratory tests showed no abnormalities except for mild anaemia. Standard transthoracic echocardiography revealed dilated coronary sinus, raising suspicion of a persistent left cranial vena cava, and the persistency of this anomaly was confirmed by agitated-saline study. Right ventricular echocardiographic parameters did not change significantly, while conventional parameters and global longitudinal strain analysis revealed left ventricular systolic dysfunction. Moreover, post-systolic shortening and early systolic lengthening were detected by two-dimensional speckle tracking echocardiography. This report shows that post-systolic shortening and early systolic lengthening may be useful diagnostic markers indicating regional left ventricular systolic dysfunction. Further studies are needed to elucidate whether persistent left cranial vena cava contributes to left ventricular systolic dysfunction or is an accidental benign finding in dogs.
期刊介绍：
Journal of Small Animal Practice (JSAP) is a monthly peer-reviewed publication integrating clinical research papers and case reports from international sources, covering all aspects of medicine and surgery relating to dogs, cats and other small animals. These papers facilitate the dissemination and implementation of new ideas and techniques relating to clinical veterinary practice, with the ultimate aim of promoting best practice. JSAP publishes high quality original articles, as well as other scientific and educational information. New developments are placed in perspective, encompassing new concepts and peer commentary. The target audience is veterinarians primarily engaged in the practise of small animal medicine and surgery.
In addition to original articles, JSAP will publish invited editorials (relating to a manuscript in the same issue or a topic of current interest), review articles, which provide in-depth discussion of important clinical issues, and other scientific and educational information from around the world.
The final decision on publication of a manuscript rests with the Editorial Board and ultimately with the Editor. All papers, regardless of type, represent the opinion of the authors and not necessarily that of the Editor, the Association or the Publisher.
The Journal of Small Animal Practice is published on behalf of the British Small Animal Veterinary Association and is also the official scientific journal of the World Small Animal Veterinary Association
