ABSTRACT
A 45-days-old mixed-breed female cat was referred to a veterinary specialty hospital for evaluation due to poor general condition, dyspnea of possible cardiac origin, and a heart murmur. The results of the physical examination, thoracic radiography, and echocardiography led to a diagnosis of hypotrophy of the right ventricle, tricuspid atresia, and atrial septal defect. Cardiovascular pathological findings confirmed the clinical diagnosis in addition to the observation of a ventricular septal defect. To the authors' knowledge, this is the first report of tricuspid atresia with atrial septal defect and ventricular septal defect in a cat.

A displasia da tricúspide, associada ou näo à anomalia de Ebstein, näo é das cardiopatias mais freqüentes em cäes (Liu; Tilley6, 1976; Eyster et al.4, 1977; Netter9, 1978; Moise8, 1994). A displasia da tricúspide caracteriza-se pelo espessamento focal ou difuso dos folhetos valvulares, subdesenvolvimento das cordoalhas tendíneas e músculos papilares, separaçäo incompleta dos componentes valvares da parede ventricular, além da agenesia do tecido valvular. Simultaneamente ou näo a esta valvulopatia congênita, pode ocorrer a inserçäo mais baixa do aparelho valvar na parede do ventrículo direito, condiçäo esta conhecida como anomalia de Ebstein (Liu, Tilley6, 1976; Eyster et al.4, 1977; Moise8, 1994). No presente relato, os autores descrevem um caso de displasia da tricúspide associada à malformaçäo de Ebstein, em cäo Weimaraner, macho, de 3 meses de idade, cujo diagnóstico clínico foi estribado no exame físico, eletrocardiográfico, radiográfico e ecocardiográfico. O animal apresentou uma sobrevida de 15 meses após a realizaçäo do diagnóstico, vindo a óbito de forma súbita e natural, e a existência das alteraçöes congênitas foram confirmadas no exame necroscópico
