[Zero-fluoroscopy transcatheter ablation and CRT-D implantation: new frontiers of electroanatomical mapping systems]

In cardiac resynchronization therapy (CRT) implantation procedures, contrast-induced nephropathy risk and ionizing radiation exposure can be eliminated using electroanatomical mapping system (EAMS). Under EAMS guidance, it is possible to place the left ventricular catheter in the branch of the coronary sinus that presents the latest activation. The use of EAMS allows for both arrhythmic ablation and CRT implantation to be obtained in a single, "zero fluoroscopy" procedure. Here we report two cases of successful arrhythmia ablation and CRT-D implantation with "zero fluoroscopy" in a single procedure.
