64-year-old man implanted with a triple-chamber defibrillator Viva XT CRT-D for idiopathic dilated cardiomyopathy with a left bundle branch block; follow-up 3 months post implant; non-responder patient with unchanged symptomatology (shortness of breath during daily activities); device interrogation reveals 100% of biventricular pacing.64-year-old man implanted with a triple-chamber defibrillator Viva XT CRT-D for idiopathic dilated cardiomyopathy with a left bundle branch b

64-year-old man implanted with a triple-chamber defibrillator Concerto II CRT-D with positioning of a Medtronic 4195 LV lead in a small lateral vein; complex implantation due to the small caliber of the veins + high threshold values + several pacing sites with a phrenic nerve capture.

70-year-old man implanted with a triple-chamber defibrillator Viva XT CRT-D and a Medtronic 4194 LV lead for ischemic cardiomyopathy with a left bundle branch block; follow-up 3 days after implant; LV threshold performed in various pacing configurations (pacing DDD 90 bpm, amplitude decrement, fixed pulse width of 0.4 ms).

62-year-old man implanted with a triple chamber defibrillator Viva Quad XT CRT-D connected to a quadripolar Medtronic 4298 LV lead for ischemic cardiomyopathy with left bundle branch block; the implantation procedure was difficult with few lateral veins of small caliber and a large inferior vein draining the lateral wall; presence of high threshold values in the apical portion of the lateral wall and phrenic nerve stimulation; positioning of a quadripolar lead; LV threshold

81-year-old man implanted with a triple chamber pacemaker Consulta CRT-P with bipolar RV and LV leads for severe ischemic cardiomyopathy with right bundle branch block; routine follow-up; the ECG shows two slightly different patterns of the paced QRS; LV pacing amplitude is set at 3.5 V/0.4 ms in a (distal) tip LV – ring (anode) RV.

64-year-old man implanted with a triple chamber defibrillator Concerto II CRT-D for ischemic cardiomyopathy with left bundle branch block; symptomatic phrenic nerve stimulation; pacing output set at 1.5 Volts/0.4 ms with a minimal margin on the pacing threshold but with no phrenic nerve stimulation; follow-up by remote monitoring; reception of an EGM tracing in the context of an Optivol alert, statistical report indicating a permanent biventricular pacing.

70-year-old man implanted with a triple chamber defibrillator Viva XT CRT-D for severe ischemic cardiomyopathy and left bundle branch block; good response to resynchronization therapy; two endocarditis episodes necessitated the complete removal of the system (first implanted on the left side, then on the right side); complete surgical re-implantation of a defibrillator with 2 coils, a bipolar atrial and RV lead and a bipolar LV lead; routine follow-up.
