This study comprised 12 hearts of Wied´s black-tufted-ear marmoset, Callithrix kuhlii (Coimbra-Filho 1985), 6 with Wasting Marmoset Syndrome (WMS) and 6 non-affected. Biometry was performed after death. After necropsy, the hearts were weighed, dissected, fixed in 10% formalin solution (pH 7.2), and processed for optical microscopy at 5µm sections stained with Haematoxylin-Eosin. Quantitative analysis was performed by stereological techniques. The statistical differences between the biometrical and stereological parameters were assessed by the Mann-Whitney test. The morphometric results showed that WMS causes a significant reduction in body and cardiac weights, and also in the volume density of vessels in those animals. Further studies are necessary to understand some of the results shown here. Neste estudo, foram utilizados corações de 12 Sagui-de-Wied, Callitrhix kuhlii (Coimbra-Filho 1985), sendo 6 animais afetados pela SEP e 6 animais normais. Após a morte foi realizada a biometria seguida de necropsia. Os corações foram fixados em formol tamponado a 10%, pesados e dissecados, sendo processados através de técnicas histológicas de rotina para microscopia óptica em cortes de 5µm corados por Hematoxilina-Eosina. As análises quantitativas foram feitas com o uso de técnicas estereológicas. As diferenças estatísticas entre os parâmetros biométricos e estereológicos foram avaliadas usando o test Mann-Whitney. Os resultados encontrados através da morfometria mostraram que a SEP causa uma redução significante do peso tanto corporal quanto do músculo cardíaco, e também uma redução no volume dos vasos nestes animais. Novos estudos são necessários para entender alguns dos resultados mostrados aqui
