Efficacy and Safety of Transvenous Lead Extraction in the Device Laboratory and Operating Room Guided by a Novel Risk Stratification Scheme.

Objectives: The goal of this study was to evaluate a novel risk stratification scheme to categorize patients on the basis of risk to either an operating room or device laboratory with rescue strategy.

Background: Lead extraction can be complicated by lethal issues such as vascular and cardiac rupture. Currently, the optimal site for lead extraction has not been well established.

Scar quantification by cardiovascular magnetic resonance as an independent predictor of long-term survival in patients with ischemic heart failure treated by coronary artery bypass graft surgery.

Background: Scar burden by late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) is associated with functional recovery after coronary artery bypass surgery (CABG). There is limited data on long-term mortality after CABG based on left ventricular (LV) scar burden.

Methods: Patients who underwent LGE CMR between January 2003 and February 2010 within 1 month prior to CABG were included.
