OBJETIVO: Mostrar o real valor da ressonância magnética cardíaca (RMC) na avaliação dos portadores de valvopatia aórtica crônica sintomática. MÉTODOS: Foram estudados 70 pacientes, 35 com estenose aórtica (EAo) e 35 com insuficiência aórtica (IAo), com indicação cirúrgica, que realizaram ecocardiograma (ECO) e RMC pré-operatórios para avaliação da função ventricular, volumes e índice de massa ventricular esquerda por meio da cinerressonância. RESULTADOS: Quando comparadas as variáveis do ECO e da RMC, nos grupos da EAo e da IAo não houve diferença estatística entre os dois métodos. Quando comparadas com o tipo de sintoma, as variáveis pelo ECO e pela RMC apresentam o mesmo comportamento. CONCLUSÃO: A RMC apresentou concordância com o ECO na avaliação do volume ventricular esquerdo e fração de ejeção e com a clínica dos pacientes com valvopatia aórtica crônica.

OBJECTIVE: To show the real value of cardiac magnetic resonance imaging (CMRI) in the evaluation of patients with symptomatic chronic aortic valve disease. METHODS: Seventy patients - 35 with aortic stenosis (AoS) and 35 with aortic regurgitation (AoR) with surgical indication, who underwent preoperative echocardiogram (ECHO) and CMRI to assess ventricular function, volumes, and left ventricular mass index using cine magnetic resonance imaging, were studied. RESULTS: No statistically significant difference was observed between the AoS and AoR groups when ECHO and CMRI variables were compared. When compared with the type of symptom, ECHO and CMRI variables showed the same pattern. CONCLUSION: CMRI data were in agreement with ECHO data regarding the assessment of left ventricular volume and ejection fraction, and with the clinical presentation of patients with chronic aortic valve disease.

We report the case of a 57-year-old male patient with severe low back pain during streptokinase infusion administered to treat typical chest pain and elevation of the ST segment in the inferior wall. We reviewed the literature, emphasizing the differential diagnosis, the pathophysiology, and management of the event.
