Septal coronary artery fistula after left bundle branch area pacing assessed by multi‐imaging modalities and shunt volume quantification.

Septal coronary artery fistula is a rare but concerning complication of left bundle branch area pacing (LBBAP). We report the case of an 82‐year‐old man who was indicated for cardiac resynchronization therapy and underwent LBBAP. The patient had no chest symptoms during or after implantation. Postoperative echocardiography demonstrated a new abnormal tunnel inside the interventricular septum (IVS) and shunt flow from the IVS toward the right ventricle. Coronary angiography confirmed a septal coronary artery fistula, which might have been formed by failed deep screw attempts. Since the shunt volume assessed by the Qp/Qs was small, the patient was treated conservatively. [ABSTRACT FROM AUTHOR]
