A dilemma in the electrophysiology lab: where is the coronary sinus in a patient with left inferior vena cava with hemiazygos continuation?

Acta Cardiol. 2012 Jun;67(3):343-6. doi: 10.1080/ac.67.3.2160725.

Abstract

Occasionally, electrophysiological interventions are complicated by an unusual or an anomalous cardiovascular anatomy. We report our experience of a case of situs ambiguous and symptomatic heart failure of which anomalous venous anatomy and coronary sinus variation had prevented a successful endocardial placement of a left ventricular lead for cardiac synchronization therapy.
