Epicardial LV lead placement can rarely cause mechanical compression and stenosis of the LAD artery, highlighting the need to consider anatomical distortion such as lateral displacement of the interventricular septum in patients with severe biventricular dilatation.

May warrant coronary proximity caution with epicardial LV leads; hypothesis-generating for septal distortion in severe dilatation.
Implantation of an epicardial left ventricular (LV) lead is a reasonable alternative to a transvenous coronary sinus lead in the case of inadequate coronary sinus anatomy, and is generally considered safe and effective. We report the case of a patient who received an epicardial LV sutureless screw-in lead presenting several months later with a myocardial infarction owing to injury to the left anterior descending (LAD) artery by the epicardial LV screw-in lead.

Krepp et al. (2016) conducted a case report in Alcohol-induced nonischemic cardiomyopathy (n=1). Epicardial left ventricular sutureless screw-in lead placement was evaluated on Left anterior descending artery stenosis and myocardial infarction. Epicardial left ventricular sutureless screw-in lead placement resulted in left anterior descending artery stenosis and myocardial infarction five months post-implantation.
