Abstract

UEMURA, Akiko et al. Transoesophageal echocardiography-guided hybrid balloon valvuloplasty for severe pulmonic stenosis in small dogs. J. S. Afr. Vet. Assoc. [online]. 2021, vol.92, n.1, pp.1-5. ISSN 2224-9435.  http://dx.doi.org/10.4102/jsava.v92i0.2012.

Pulmonic stenosis (PS) is the most common congenital heart disease in dogs and is commonly seen in small breeds, such as Chihuahuas. Conventional treatments have limitations specific to small dogs, including the invasive nature of open-heart surgery and size limitations in percutaneous balloon valvuloplasty. Here, transoesophageal echocardiography (TEE)-guided balloon valvuloplasty via thoracotomy was performed for three small dogs with PS. The procedure was feasible in all cases, including those for which percutaneous treatment was not an option. Although the procedure is invasive, because of the need for thoracotomy, it is one of the treatment options that may be effective for PS, especially in small dogs, as it allows visualisation of the pulmonary artery lesion without relying on the experience of the surgeon.

Keywords : dog; balloon valvuloplasty; small breed; thoracotomy; transoesophageal echocardiography.
