RESUMO
BACKGROUND: There are limited reports of severe tricuspid valve stenosis in dogs and limited data regarding treatment and outcome. OBJECTIVE: To evaluate clinical signs, echocardiographic features, and outcome of balloon valvuloplasty (BV) in dogs with severe tricuspid valve stenosis (TVS) in which BV was attempted. ANIMALS: Five client-owned dogs with severe TVS. METHODS: Records were retrospectively reviewed and data collected regarding signalment, clinical signs, diagnostic findings, procedures, and outcome. RESULTS: All dogs were Labrador Retrievers. Presenting complaints included episodic weakness/syncope (4/5), abdominal distension (4/5), lethargy (2/5), and exercise intolerance (2/5). The median and range of measurements before BV were as follows: TV mean velocity 1.5 m/s (range 1.4-1.7 m/s); velocity-time integral (VTI) 79.8 cm (42.4-99.1 cm); and TV maximum velocity 2.9 m/s (2.3-3.2 m/s). Measurements (available for 3 of 5 dogs) after BV were as follows: TV mean velocity 1.15 m/s (0.9-1.4 m/s); VTI 44.95 cm (41.4-54.8 cm); and TV maximum velocity 1.15 m/s (1.9-2.3 m/s). The procedure was attempted in all dogs and completed in 4/5 dogs. The largest balloon diameter ranged from 15 mm to 25 mm, and length ranged from 4 cm to 5 cm. Right atrial pressure decreased in 4/5 dogs. All but 1 dog had clinical improvement after BV, but recurrence of clinical signs occurred (2/5). Tricuspid regurgitation worsened in 1 dog culminating in right heart failure and euthanasia. CONCLUSIONS AND CLINICAL IMPORTANCE: BV can be an effective treatment; however, clinical signs can recur. Right heart failure due to worsened TR is a potential complication in dogs with pre-existing moderate-to-severe TR.

La estenosis pulmonar (EP) es un defecto cardíaco congénito relativamente común en perros, puede estar presente solo o en asociación con otros defectos cardíacos congénitos como la displasia tricuspidea (DT). Ambas condiciones pueden conducir a insuficiencia cardíaca derecha. El presente trabajo pretende revisar brevemente la literatura y describir el caso citado de un perro, 10 meses, raza blue heeler que fue atendido con disminución del apetito, aumento del volumen abdominal y disnea. Después del tratamento inicial se realizó examen ecocardiograma, que era compatible con estenosis pulmonar y displasia tricuspídea.
Pulmonic stenosis (PS) is a relatively common congenital heart defect in dogs and may be present alone or in association with other congenital heart defects such as tricuspid dysplasia (TD). Both conditions can potentially lead right heart failure. This paper aims to describe a case of a 10-month old blue heeler dog which was presented with a history of decreased appetite, increased abdominal volume and dyspnea. After the first medical aid, the animal was sent to echocardiogram, which was compatible with pulmonic stenosis and tricuspid dysplasia.
A estenose pulmonar (EP) é uma cardiopatia congênita relativamente comum em cães, podendo estar presente isoladamente ou em associação a outras cardiopatias congênitas, como a displasia de válvula tricúspide (DT). Ambas as condições podem potencialmente levar a insuficiência cardíaca congestiva direita. Esse trabalho tem como objetivo descrever o caso de um cão de 10 meses da raça blue heeler atendido com histórico de hiporexia, aumento de volume abdominal e dispneia. Após o atendimento inicial, o animal foi encaminhado para exame de ecocardiograma que mostrou imagem compatível com estenose pulmonar e displasia de tricúspide.
