Biventricular Pacemaker Implantation in an Elderly Patient with Situs Inversus Dextrocardia

Dextrocardia is a rare anomaly having an incidence of 0.83/10.000 (1). Approximately one-third of dextrocardia cases have situs inversus dextrocardia (SID), where cardiac chambersare located in the mirror image of their usual locations. Although other congenital defects may accompany this anomaly, many patients have normally functioning hearts, and when they age, they face common cardiac disorders, namely coronary heart diease and heart failure and require pacemaker implantation. The number of papers reporting biventricular pacemaker implantation in these patients is limited (2). We report a woman with SID who underwent biventricular cardiac pacemaker implantation for advanced heart failure.
