Description
Summary:Systolic anterior motion (SAM) is a postoperative complication of mitral valve repair, with an incidence of 5–10%. Early recognition of the signs and symptoms of SAM is essential for the management of these patients. This article focuses on the pathophysiology and dynamics of SAM and the treatment strategies described in the literature. The authors present a case study and echocardiographic images illustrating the clinical relevance of the mechanism involved, in order to clarify whether surgical reintervention is necessary. Resumo: O movimento anterior sistólico (SAM) é uma complicação pós cirúrgica da valvuloplastia mitral, sendo a sua incidência de 5-10%. O reconhecimento precoce dos sinais e sintomas de SAM é imperativo no delinear de estratégia terapêutica nesses pacientes. Este artigo foca os principais mecanismos fisiopatológicos do SAM dinâmico e modalidades de tratamento descritas na literatura. Os autores descrevem um caso clínico e as imagens ecocardiográficas captadas ilustrando a relevância clínica do mecanismo envolvido, na tentativa de esclarecer uma questão suscitada: reintervenção cirúrgica necessária?
