Three-vessel myocardial bridging: A possible cause of myocardial stunning

The authors report a rare clinical case of myocardial bridging of the three major coronary arteries, which manifested in an unusual way with severe biventricular dysfunction in the context of tachycardia. For the diagnosis, the authors relied on non-invasive multimodality cardiac imaging, including...

Description
Summary:The authors report a rare clinical case of myocardial bridging of the three major coronary arteries, which manifested in an unusual way with severe biventricular dysfunction in the context of tachycardia. For the diagnosis, the authors relied on non-invasive multimodality cardiac imaging, including cardiac magnetic resonance, computed tomography angiography and myocardial perfusion scintigraphy. The implementation of targeted medical and neurohormonal therapy resulted in the recovery of ventricular function and clinical improvement. Resumo: Os autores descrevem um caso clínico raro de bridging miocárdico dos três territórios coronários, que se apresentou de forma invulgar com disfunção biventricular grave em contexto de taquicardia. Para o diagnóstico os autores basearam-se em exames de imagem cardíaca não invasivos, como a ressonância magnética cardíaca, a angiografia tomográfica computorizada e a cintigrafia de perfusão miocárdica. A instituição de terapêutica médica dirigida e neuro-hormonal permitiu a recuperação da função ventricular e a melhoria clínica.
