Background: Complete heart blocks underwent to permanent pacemaker placement are a common complication\nof tricuspid valve replacement (TVR). If indicated, endocardial placement of a right ventricular (RV) lead is precluded\nin the presence of mechanical TVR.\nCase presentation: A 20-year-old female patient firstly underwent metallic prosthetic valve operation with tricuspid\nvalve endocarditis in 2014. Three years after the operation, echocardiography revealed dysfunction of the prosthetic\nvalve thus reoperation was decided. In the second operation, the patient underwent a bioprosthesis valve and AV\ncomplete block developed in the postoperative period. Left ventricular ejection fraction (EF) was 45% was found on\nechocardiography. Pacemaker dependence of the patient, it was aimed to place two electrodes into the left\nventricle. Electrodes were placed the target two branches in coronary sinus (CS) and right atrium. Univentricular\nbifocal pacing was enabled to work.\nConclusion: Electrode placement in the CS is a very good alternative to epicardial surgical lead placement in cases\nwhere endocardial lead placement from the right atrium to the RV is contraindicated. In patients with lower left\nventricular EF who will be pacemaker dependent, the insertion of two electrodes into the CS to prevent pacemaker\nis a safe and effective treatment.
