Dynamic Coronary Artery Compression by Pacemaker Lead

Dynamic coronary artery compression by pacemaker lead.

A 12 year-old girl with corrected transposition (Ltransposition of the great arteries with ventricular inversion) and congenital complete atrioventricular block underwent epicardial pacemaker implantation with a single ventricular lead at 1 week of life. Subsequently, she presented for routine follow-up care in the electrophysiology clinic with no symptomatic concerns. She denied chest pain. He...

Left main coronary artery compression by an enlarged pulmonary artery.

Coronary vein balloon angioplasty for left ventricular pacemaker lead implantation.

OBJECTIVES Retrospective analysis of five cases of coronary vein balloon angioplasty performed to allow insertion of left ventricular pacing leads. BACKGROUND Coronary vein stenoses or an insufficient vessel caliber can preclude transvenous placement of coronary vein leads. METHODS We compared our total patient population (n = 218), in whom we implanted coronary vein leads, to those five pa...

Remnant Pacemaker Lead Tips after Lead Extractions in Pacemaker Infections

Complete hardware removal is recommended in the case of patients with cardiovascular implantable electronic device (CIED) infections. However, the complete extraction of chronically implanted leads is not always achieved. The outcomes and optimal management of CIED infections with retained material after lead extractions have not been elucidated. In this case report, we present five patients wi...

Pacemaker Lead Endocarditis Caused by Achromobacter xylosoxidans

We report the case of a 35-yr-old patient who presented with high fever and chills. He had undergone a patch closure of the ventricular septal defect 18 yr before. One year later, a VVI pacemaker was implanted via the right subclavian vein because of complete heart block. Nine years after that, a new VVI pacemaker with another right ventricular electrode was inserted controlaterally and the old...
