Hybrid Transcatheter Approach to an Iatrogenic Left Ventricle–Coronary Sinus Fistula

This clinical case describes a subacute presentation of decompensated heart failure secondary to an iatrogenic left ventricle-to-coronary sinus fistula after sequential mitral valve surgical procedures. Computed tomography was used to select an unconventional hybrid transapical access approach and facilitate successful closure using a vascular plug.
