Surgical thrombectomy with catheter conservation resolves rare LV lead thrombosis in a biventricular ICD patient.
Case Report (n=1)
Surgical thrombectomy with lead conservation and anchoring can be a viable treatment for left ventricular lead thrombosis in patients with biventricular ICDs.
May offer a lead-conserving option for rare LV lead thrombosis; leaves open generalizability and need for prospective validation.
Right cardiac thrombosis is an infrequent complication after pacemaker implant. We report a patient who received a biventricular implantable cardioverter defibrillator, with a large mobile thrombus, adherent to the left ventricular lead. This catheter was partially dislocated, with a large, mobile loop through the right atrium and right ventricle; so the lead thrombus could alternately obstruct the pulmonary valve and the tricuspid valve. We believe that this is the first case of left ventricular lead thrombosis, in which the surgical treatment included thrombectomy with conservation of the catheter that was anchored to the internal right atrial wall in order to limit its great motility, maintaining the contribution to the cardiac resynchronization.

Paino et al. (2008) conducted a case report in Biventricular pacemaker lead thrombosis (n=1). Surgical thrombectomy with conservation of the catheter was evaluated. Surgical thrombectomy with conservation of the catheter was successfully used to treat a rare case of left ventricular lead thrombosis in a patient with a biventricular ICD.
