Key result
Nonsurgical partial withdrawal of a left ventricular pacing lead using a deflectable catheter successfully eliminated intractable diaphragmatic stimulation while preserving biventricular pacing at 3 months.

Does nonsurgical partial withdrawal of an LV pacing lead eliminate intractable diaphragmatic stimulation while preserving LV pacing?
Nonsurgical retraction of an LV lead using a deflectable catheter can successfully eliminate diaphragmatic stimulation while preserving biventricular pacing.

May enable nonsurgical resolution of diaphragmatic stimulation while preserving LV pacing; leaves open durability and generalizability.
This report describes the nonsurgical elimination of intractable diaphragmatic stimulation by partial withdrawal of a left ventricular (LV) pacing lead (in the coronary venous system) with resultant preservation of LV pacing. The procedure entailed the use of a deflectable catheter in the right atrium for ensnaring the LV lead. At the 3-month follow-up, the absence of diaphragmatic stimulation was associated with a satisfactory LV pacing threshold and dramatic clinical improvement from effectual biventricular pacing.

Herweg et al. (2009) conducted a case report in Intractable diaphragmatic stimulation from a left ventricular pacing lead (n=1). Nonsurgical retraction of a left ventricular lead using a deflectable catheter was evaluated on Elimination of diaphragmatic stimulation and preservation of LV pacing. Nonsurgical partial withdrawal of a left ventricular pacing lead using a deflectable catheter successfully eliminated intractable diaphragmatic stimulation while preserving biventricular pacing at 3 months.
