When we implant leadless pacemaker in patients with contrast agent allergy or poor renal function, the use of sufficient contrast agent is hesitant. Aided by imaging assessment (e.g., intracardiac echocardiography), the procedure may be feasible with a small amount of contrast medium or no contrast medium. In this case, leadless pacemaker implantation was performed at the same time as the transcatheter mitral valve repair, and leadless pacemaker implantation was successful with the use of a very small amount of contrast medium under transesophageal echocardiography guidance.
Keywords: leadless pacemaker; transcatheter mitral valve repair; transesophageal echocardiography.
