case_images: A coronary CT angiography with calcium scoring and 3D reconstruction was performed to rule out the possibility of coronary artery disease with minor unstable lesions ( Figure 3 ) since the patient smoked and presented with an acute coronary syndrome evolving to ventricular segmental dysfunction. Therefore, AM surgical resection ( Figure 3 ) was performed without valve replacement and complications.
