Estas s\u00e3o imagens de um ecodopplercardiograma realizado em um paciente da ra\u00e7a boxer, de 7 anos de idade, para avalia\u00e7\u00e3o pr\u00e9-anest\u00e9sica de cirurgia eletiva. Apesar de o tutor relatar que seu animal era sadio, ao exame f\u00edsico o cl\u00ednico geral detectou sopro card\u00edaco sist\u00f3lico em foco a\u00f3rtico grau III\/VI, levando a suspeita de uma cardiopatia. Foi ent\u00e3o solicitado pelo nosso parceiro a realiza\u00e7\u00e3o do ecodopplercardiograma sendo poss\u00edvel diagnosticar a estenose valvar a\u00f3rtica de grau moderado.<\/p>\n

Dentre as anomalias cong\u00eanitas vasculares, a estenose a\u00f3rtica \u00e9 uma das mais comuns em c\u00e3es (MAGALH\u00c3ES et al., 2014).<\/p>\n

A estenose a\u00f3rtica (EA)<\/strong> \u00e9 caracterizada por um estreitamento ou redu\u00e7\u00e3o, localizada na dimens\u00e3o do sistema de fluxo causando uma sobrecarga de press\u00e3o (GOODWIN et al., 2010 citado por MAGALH\u00c3ES et al., 2014). \u00c9 um defeito cong\u00eanito que acomete ra\u00e7as grandes (MAcPHAIL, 2013), e parece predispor c\u00e3es da ra\u00e7a Boxer (KIENLE et al., 1994), Golden Retriever (O’GRADY et al., 1989) e Rotweiller (MEURS, 2010 citado por MAGALH\u00c3ES et al., 2014).<\/p>\n

Os sinais cl\u00ednicos de EA podem ser assintom\u00e1ticos ou podem apresentar intoler\u00e2ncia ao exerc\u00edcio, colapso ou s\u00edncope. A falta de sinais cl\u00ednicos n\u00e3o \u00e9 uma raz\u00e3o para retardar a avalia\u00e7\u00e3o diagn\u00f3stica, pois a primeira evid\u00eancia de EA pode ser a morte s\u00fabita (MAcPHAIL, 2013 citado por MAGALH\u00c3ES et al., 2014). O achado f\u00edsico predominante nos animais acometidos com EA \u00e9 sopro sist\u00f3lico, melhor aud\u00edvel na base do cora\u00e7\u00e3o, em casos moderados a graves, pulsos femorais podem ser fracamente vis\u00edveis (KIENLE et al., 1994; OYAMA et al., 2010; MAcPHAIL, 2013 citado por MAGALH\u00c3ES et al., 2014).<\/p>\n

Exames diagn\u00f3sticos incluem o eletrocardiograma, que mostra uma mudan\u00e7a de eixo cranial esquerda ou ectopia ventricular, sendo esses achados normais para a EA (McCONKEY, 2011; MAcPHAIL, 2013 citado por MAGALH\u00c3ES et al., 2014), radiografia tor\u00e1cica, que pode revelar uma silhueta card\u00edaca normal e alargamento do \u00e1trio esquerdo, com amplia\u00e7\u00e3o da aorta ascendente. O exame de ecocardiografia define o diagn\u00f3stico de EA, onde se evidencia espessamento das paredes do ventr\u00edculo esquerdo e insufici\u00eancia card\u00edaca de mitral (McCONKEY, 2011; MENEGAZZO et al., 2012 citado por MAGALH\u00c3ES et al., 2014). A EA deve ser diferenciada de outras condi\u00e7\u00f5es que causam sopro sist\u00f3lico como, por exemplo, tetralogia de Fallot ou estenose pulmonar (GOODWIN, 2002 citado por MAGALH\u00c3ES et al., 2014).<\/p>\n

Terapia com bloqueadores \u03b2-adren\u00e9rgicos como propranolol ou atenolol podem reduzir o risco de morte s\u00fabita, diminuindo a necessidade de oxig\u00eanio do mioc\u00e1rdio e suprimir arritmias ventriculares durante o exerc\u00edcio. O tratamento com furosemida, enalapril pode ser indicado para casos assintom\u00e1ticos. A interven\u00e7\u00e3o cir\u00fargica deve ser considerada para c\u00e3es com hipertrofia ventricular esquerda evidente, sendo feita no in\u00edcio para minimizar as altera\u00e7\u00f5es mioc\u00e1rdicas degenerativas (MAcPHAIL, 2013 citado por MAGALH\u00c3ES et al., 2014).<\/p>\n
