  • Title: Pacing from the right ventricular septum: is there a danger to the coronary arteries?
    Author: Teh AW, Medi C, Rosso R, Lee G, Gurvitch R, Mond HG.
    Journal: Pacing Clin Electrophysiol; 2009 Jul; 32(7):894-7. PubMed ID: 19572865.
    Abstract:
    BACKGROUND: Pacing from right ventricular (RV) septal sites has been suggested as an alternative to RV apical pacing in an attempt to avoid long-term adverse consequences on left ventricular function. Concern has been raised as to the relationship of the left anterior descending coronary artery (LAD) to pacing leads in these positions. METHODS AND RESULTS: We retrospectively analyzed three cases in which patients with RV active-fixation leads in situ also had coronary angiography. Multiple fluoroscopic views were used to determine the relationship of the lead tip at various pacing sites to the coronary arteries. A lead placed on the anterior wall was in close proximity to the LAD, whereas septal and free wall positioning was not. CONCLUSION: Placement of RV active-fixation leads on the septum avoids potential coronary artery compromise.
